1. Installation

Thank you for purchasing imaging products from EPIX, Inc. We are available via email, telephone, or FAX to help with installation or to answer questions about the use of our products.

The PIXCI® A310 frame grabber, for the PCI Express bus, is packed in a static dissipative bag. Prior to opening the bag, place the bag near the computer into which the frame grabber will be installed.

We recommend installing XCAP prior to installing the PIXCI® frame grabber. Please refer to the Software Installation chapter for the XCAP installation directions, then follow the frame grabber installation instructions below. Installing XCAP software, which includes the PIXCI® frame grabber drivers, prior to installing the PIXCI® frame grabber isn't required, but more convenient.

1.1. Instructions

Use of a static free area and a wrist strap connected to the computer or to the static free area is suggested during installation. Walking can generate static electricity. Keep your feet stationary while removing the PIXCI® frame grabber from the anti-static bag. Hold the bag and the computer at the same time, or place the bag on the computer chassis and touch the chassis to dissipate the static charge that may have been created while transporting the frame grabber to the computer.
Power down the computer, and remove the power from all equipment to be connected.
Select a vacant PCI Express slot and remove the metal bracket and screw covering the back panel slot with which it is aligned. Consult the manual for the computer if there is any doubt about which slot is a PCI Express slot.
Remove the PIXCI® frame grabber from the anti-static bag and insert it into the PCI Express slot. Do not use excessive force. If the frame grabber is not lined up with the slot correctly, excessive force can cause damage to the slot and the frame grabber.
Replace the screw to secure the PIXCI® frame grabber in the slot.
Connect the cable(s) between the PIXCI® frame grabber, camera, and power supply. Connect the video source to either the upper BNC connector (for composite monochrome sources) or to all three of the BNC connectors (for component RGB sources; top BNC connector is for Green, middle BNC connector is for Red, and bottom BNC connector is for Blue). If using a video source that requires a separate sync signal, connect the sync signal to the 15-pin DB15 connector. The pinout of the DB15 connector is described in section 2 of this manual.
Power up the camera and computer.
Install (if not done previously) and run the XCAP application software, following the instructions in the Software Installation and the Getting Started with XCAP chapters. In case of problems, refer to the In Case of Trouble chapter.

1.2. Computer

The size and the number of images that can be stored in memory on the motherboard is a function of the amount of memory that can be spared by the operating system. The amount of memory requested by XCAP by default depends on the operating system. If more memory is required for image sequences, the ''Driver Assistant'' (via the menubar's PIXCI®, PIXCI® Open/Close) can be used to request additional frame buffer memory. Some operating systems may require up to 2 gigabytes to operate efficiently.

The PIXCI® frame grabbers can capture and store full resolution images to computer memory (RAM) on a PCI Express motherboard. The PIXCI® frame grabbers have been tested at sustained data rates of 700 megabytes per second, and burst rates of 1000 megabytes per second for an x4 slot and x4 frame grabber. Wider PCI Express slots may be used for the PIXCI frame grabbers, but note that some x16 slots (e.g. motherboards using the 915 chip set) will only operate in x1 or x16 capability, resulting in slower data rates. Each PCI Express slot on a motherboard may exhibit different performance characteristics. If the motherboard manufacturer doesn't indicate the slot which supports the highest bandwidth, try all slots.

EPIX, Inc. is an Intel approved, value added reseller and can assemble computer based imaging systems including camera(s), RAID video to disk systems, power supplies, monitors, and cables that have been tested to specific sustained data rates prior to shipment.

2. Connectors

The PIXCI® A310 frame grabber has four connectors which are accessible through the bracket that mounts the frame grabber to the computer chassis. From the top of the bracket to the bottom, the connectors are: BNC1, BNC2, BNC3, and J1. Silkscreen labels identify each connector on the PIXCI® A310 frame grabber. The PIXCI® A310 frame grabber also has one 10 pin header, which can be found on the front surface of the frame grabber.

2.1. BNC Connectors

BNC1: An analog video input connector. BNC1 should be used for monochrome video sources, and for the Green signal of component RGB sources. By default, the video signal on BNC1 is used to generate the video sync signals. The analog video input signal level should be 1 volt peak to peak with the video portion positive and the sync tips negative. The minimum composite video input signal that can be amplified to provide 0 through 255 grey levels is 0.5 volts peak to peak. The maximum composite video input signal is 2 volts peak to peak. The input is terminated in 75Ω to ground.
BNC2: An analog video input connector. BNC2 should be used for the Red signal of component RGB sources. The technical specifications of the signal at BNC2 are otherwise similar to the specifications of the signal at BNC1.
BNC3: An analog video input connector. BNC3 should be used for the Blue signal of component RGB sources. The technical specifications of the signal at BNC3 are otherwise similar to the specifications of the signal at BNC1.

2.2. DB15 Connector

The connector is a female 15 pin D-Subminiature connector (TE Connectivity PN 1-1734530-3). Eight pins are used for external inputs. Five pins are connected to ground. Two pins are reserved for possible future use.

3. Software Installation

XCAP-Plus, XCAP-Std, XCAP-Ltd, and XCAP-Lite are easy to install by following the instructions below.

3.1. For Windows 8/10/11/ 32/64-Bit

Administrator privileges are required to complete the installation procedure.

Install Files:
1. If XCAP is provided on a CD or DVD:
  1. If your computer is set to allow automatic execution of a loaded CD/DVD, the CD/DVD's interactive index program will be executed automatically. Otherwise, execute the index program, from a Command Prompt (i.e. Windows Terminal), or via the Windows ''Start'', ''Run'':
```
    > Z:SETUP       (replace Z with drive letter for your CD/DVD)
```
  2. Select ''Setup PIXCI(R) Imaging Software'' and ''XCAP Imaging Application for Windows 10/8/7/Vista/XP/2000 32-Bit'' or ''XCAP Imaging Application for Windows 11/10/8/7/Vista/XP 64-Bit''. Click ''OK''.
  3. Follow the installation program's directions, such as to select an installation directory. The default installation directory is nominally C:\Program Files\EPIX\XCAP, or C:\Program Files(x86)\EPIX\XCAP for installation of 32-bit XCAP on 64-bit Windows, but depends on the current Windows' CSIDL settings.
2. If XCAP is provided via the internet:
  1. Download:
```
ftp.epixinc.com/software/xcap_v38/XCAPWIN32.EXE (for 32-bit XCAP for Windows)
```
    or
```
ftp.epixinc.com/software/xcap_v38/XCAPWIN64.EXE (for 64-bit XCAP for Windows)
```
    from the EPIX, Inc. ftp site.
  2. Execute the downloaded program, from a Command Prompt (i.e. Windows Terminal), or via the Windows ''Start'', ''Run'':
```
> XCAPWIN32.EXE     (for 32-bit XCAP for Windows)
```
    or
```
> XCAPWIN64.EXE     (for 64-bit XCAP for Windows)
```
  3. Follow the installation program's directions, such as to select an installation directory. The default installation directory is nominally C:\Program Files\EPIX\XCAP, or C:\Program Files(x86)\EPIX\XCAP for installation of 32-bit XCAP on 64-bit Windows, but depends on the current Windows' CSIDL settings.
  4. The downloaded .EXE file may be deleted.
3. The installation procedure creates a new program group, containing XCAP and several .TXT files. The *.TXT files contain these installation instructions, a list of distributed files, corrections or additions to this manual, or other up-to-date information. The PCITIPS.TXT file provides the PCI Configuration Tips, with tips for resolving hardware and software conflicts. The installation procedure also, optionally, creates a desktop shortcut for XCAP.
Install Authorization Key (for XCAP-Plus, XCAP-Std, and XCAP-Ltd):
1. XCAP-Plus, XCAP-Std, and XCAP-Ltd are provided with an USB authorization key. XCAP-Lite is provided with a software Activation ID Code.
  The Blue (older) or Green (newer) authorization USB key has the size and shape of a USB thumb drive (4 to 6&times1.6×0.8 cm) with a standard USB-A 4-pin connector. If provided, connect the authorization key to a USB port.
  
  The authorization key must remain attached, to the USB port while XCAP is running. If the authorization key is missing, or disconnected while XCAP is running, then XCAP-Plus, XCAP-Std or XCAP-Ltd, will behave similar to the XCAP-Lite version; selected image processing and analysis tools will not be operational.
2. Upon first use, XCAP will prompt for configuration as per the authorization key (including installation of drivers), or the software Activation ID Code.
  Subsequently, use Change Setup under Utility, Program Setup within XCAP, to change XCAP's configuration as per the authorization key or the software Activation ID Code.
Install PIXCI® Frame Grabber Driver:
1. The PIXCI® frame grabber's driver may be installed in response to the Windows Device Manager's prompts (it will prompt once after detecting a newly installed card) and pointing the Device Manager to Drivers\Win8 or Drivers\Win10 for Windows 8/10 32-Bit, or Drivers\Win8x64, Drivers\Win10x64, or Drivers\Win11x64 for Windows 8/10/11 64-Bit within the chosen installation directory. Or may be installed during XCAP's installation (such as via the XCAPWIN32.EXE or XCAPWIN64.EXE installer). Or may be installed by the Driver Assistant feature within XCAP.
  Alternately, the PIXCI® frame grabber's driver can be installed as follows.
2. Open the Windows Device Manager by right-clicking on the lower left corner of the screen and select ''Device Manager''. In the Device Manager look for an entry with a yellow exclamation mark that is labeled ''PCI Device'' or ''Multimedia Controller'' or ''Coprocessor'' or ''Unknown Device''. Double-click on the entry and then click the ''Update Driver...'' button. In the ''Update Driver Software'' window that pops-up, select ''Browse my computer for driver software''; in the ''Search for driver software in this location'' enter path Drivers\Win8 or Drivers\Win10 for Windows 8/10 32-Bit, or Drivers\Win8x64, Drivers\Win10x64, or Drivers\Win11x64 for Windows 8/10 64-Bit and 11 64-Bit, within the chosen installation directory (typically C:\XCAP or C:\Program Files\EPIX\XCAP or C:\Program Files(x86)\EPIX\XCAP), and click ''Next''. A window reports ''Windows has successfully updated your driver software.'' click ''Close'' and restart Windows.
3. Alternately, using the Windows Explorer, highlight file EPIXXCW2.INF within Drivers\Win8 or Drivers\Win10 for Windows 8/10 32-Bit, or highlight file EPIXXCW6.INF within Drivers\Win8x64, Drivers\Win10x64, or Drivers\Win11x64 for Windows 8/10 64-Bit and 11 64-Bit, within the chosen installation directory, right-click and select ''Install'', and restart Windows.
Restart Windows. (Note that using Windows' Shutdown instead of Restart may delay Windows' recognition of these changes until the second subsequent shutdown!)
XCAP is now ready to run, by clicking the optional shortcut, or by clicking ''Start'', ''Programs'', ''XCAP Imaging'', and finally ''XCAP for Windows''.

3.2. Windows 8/10/11 32/64-Bit Esoterica

3.2.1. Windows 8/10/11 32/64-Bit - Frame Grabber Driver Installation Details

The PIXCI® frame grabber's driver consists of files:

    EPIXXCW2.INF
    EPIXXCW2.CAT
    EPIXXCW2.SYS

for Windows 8/10 32-Bit, or files:

    EPIXXCW6.INF
    EPIXXCW6.CAT
    EPIXXCW6.SYS

for Windows 8/10/11 64-Bit. Driver files for different versions of Windows, although with the same file name, may have different digital signatures as required by each version of Windows.

The PIXCI® frame grabber driver is installed by the Windows Device Manager, or by Driver Assistant within XCAP.

Installation copies the driver files and creates registry entry:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW2

for Windows 8/10 32-Bit, or

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW6

for Windows 8/10/11 64-Bit. Most values within the registry entry are set by the Device Manager and should not be modified. The value:

    PIXCI   =  -IM <memorysize>  ...

may be created upon installation, added or modified by XCAP, or can be added or modified manually (i.e. via the Registry Editor (REGEDIT)); its component value(s) are Driver Configuration Parameters, as described below.

3.2.2. Windows 8/10/11 32/64-Bit - Frame Buffer Memory Allocation

Under Windows 8/10 32/64-Bit and 11 64-Bit, frame buffer memory must be allocated during Windows' initialization.

Use of the Driver Assistant within XCAP, provides convenient configuration of frame buffer memory allocation. The following information allows manual configuration, correcting problems, or integration with an OEM's procedures.

The requested frame buffer memory size must be specified in the Registry entry described above, using an entry named ''PIXCI'', such as:

    PIXCI         =  "-IM <memorysize>"

replacing the ''<memorysize>'' with the desired memory size in KiBytes. If no frame buffer memory size is specified, a default size of 32768 KiBytes is used. Windows must be restarted for the new specification to take effect. Note that using Windows' Shutdown instead of Restart may delay Windows' recognition of these changes until the second subsequent shutdown!

Optionally,

    "-MB <memory_partition_size>"

specifies that the requested

    "-IM <memorysize>"

is to be allocated in blocks or partitions of the stated size. Requesting memory partitioned into blocks may allow receiving more memory that would be available as a single block. However, (a) Each frame buffer must be completely contained within a partition, and (b) The maximum number of partitions is 256 under 32 bit operating systems, the maximum number of partitions is 256 under 64 bit operating systems. Systems with very high resolution cameras using large frame buffers should choose the partition size carefully, so as to minimize the unusable memory remaining, smaller than a frame buffer, at the end of each partition.

For the PIXCI® CL3SD and SI2, which have on-board frame buffer memory, memory reserved by the -IM parameter is needed as a DMA buffer (approximately 1 MiByte) and optionally for support of time stamping of captured frames as specified by the ''-MU'' parameter (see PIXCI® Driver Esoterica) specifies use of frame buffer memory for that purpose. Currently, 64 bytes are needed for each frame buffer's capture status.

Windows 8/10 32/64-Bit and 11 64-Bit limits the maximum amount of allocatable frame buffer memory, dependent upon what other devices are installed, the total computer memory size, and other factors. Under Windows 8/10/11 32-Bit, the amount of memory that Windows may grant during startup is typically limited to 1024 MiByte, but not more than half of the computer memory size. Under Windows 8/10/11 64-Bit, the amount of memory that Windows may grant during startup has not yet been determined, but is probably similar to the limit for Windows Vista 64-Bit: the smaller of 6 GiByte or one half of the computer memory size.

Windows may provide less frame buffer memory than was requested. If no memory could be allocated, the PIXCI® frame grabber will not be available, stating ''Can't allocate frame buffer memory''. Otherwise, within XCAP, the number of available frame buffers can be checked under PIXCI®, PIXCI® Video Setup, Resolution. As the frame buffer memory is allocated once during Windows initialization; the contents of frame buffers are retained as XCAP is closed and restarted, but lost if Windows is restarted.

3.2.3. Windows 8/10/11 32/64-Bit - Forceful Frame Buffer Memory Allocation

As described above, frame buffer memory allocated by EPIXXCW2.SYS for Windows 8/10 32-Bit, or EPIXXCW6.SYS for Windows 8/10/11 64-Bit, during Windows startup may be limited to a small percentage of total computer memory. Under Windows 8/10 32-Bit, the amount of memory that Windows may grant during startup is typically limited to 1024 MiByte, but not more than half of the computer memory size. Under Windows 8/10/11 64-Bit, the amount of memory that Windows may grant during startup has not yet been determined, but is probably similar to the limit for Windows Vista 64-Bit: the smaller of 6 GiByte or one half of the computer memory size. Some computer and/or Windows configurations may have lower limits.

A larger frame buffer memory can be obtained by limiting the amount of memory recognized by Windows, and then instructing EPIXXCW2.SYS for Windows 8/10 32-Bit, or EPIXXCW6.SYS for Windows 8/10/11 64-Bit, to explicitly use a section of memory without allocating it from Windows.

Use of the Driver Assistant within XCAP, provides convenient configuration of forceful frame buffer memory allocation. The following information allows manual configuration, correcting problems, or integration with an OEM's procedures.

Use the Windows' BCDEDIT utility to create a copy of the ''{CURRENT}'' boot entry, set the new entry use limit memory usage via ''truncatememory'', and changing the new entry's description.
Typical commands are:
```
    BCDEDIT  /enum
```
to list current entries and obtain the current entry's description,
```
    BCDEDIT  /copy  {current}  /d  "CURRENT_ENTRY_DESCRIPTION [PIXCI=##M NT=##M"
```
to create a new entry with modified description and boot prompt including a reminder of the amount of memory provided to Windows and to the PIXCI® imaging card,
```
    BCDEDIT /enum  /v
```
to get the ID of the new entry, and:
```
    BCDEDIT /set <new_entry_id> truncatememory <memory_size>
```
to limit the Windows memory size to <memory_size>, in bytes.
Also using BCDEDIT change the timeout selection to be greater than 0:
```
    BCDEDIT /timeout 30
```
Otherwise the boot configuration options will not be shown when Windows starts.
Edit the registry entry:
```
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW2
```
for Windows 8/10 32-Bit, or
```
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW6
```
for Windows 8/10/11 64-Bit. On the ''PIXCI'' field add:
```
    -IA <image_memory_adrs_in_KiByte>
    -IM <size_of_image_memory_in_KiByte>
    -MB <image_memory_partition_size_in_KiByte>
    -BH <size_of_BIOS_hole_below_4GiB_in_KiByte>
```
In practice, all four fields are on the same line.
The -MB partition size specifies the size into which image memory is partitioned for the sake of virtual memory management: (a) Each frame buffer must be completely contained within a partition, (b) A value of 0 specifies that the entire image memory is to be handled as one partition, and (c) The maximum number of partitions is 256 under 32 bit operating systems, the maximum number of partitions is 256 under 64 bit operating systems. For most systems, a value of 8192 or 16384 is suggested; though the value need not be a power of two. Systems with very high resolution cameras using large frame buffers should choose the partition size carefully, so as to minimize the unusable memory remaining, smaller than a frame buffer, at the end of each partition.

When using more than 1 or 2 GiBytes of image memory, it may be necessary to append:
```
    -MU 0x01
```
to the ''PIXCI'' field, conserving system memory mapping resources by not mapping the image memory directly into the application program's space. It may also be necessary to append:
```
    -MU 0x03
```
which additionally conserves system resources by mapping memory only on demand.
Be careful that the -IA address is equal to (or above) the specified ''truncatememory'' limit - including exact base2 to base10 conversions! Likewise, be certain that the -IA plus -IM values do not exceed the amount of memory available!

On a computer populated with 4 or more GiBytes of memory, some of the memory directly below the 4 GiByte address overlaps other hardware resources such as BIOS, memory mapped I/O, PCI configuration space, etc.^[1] and is unavailable to either the operating system or for use as frame buffers. The usable frame buffer memory is therefore reduced by the amount by which the -IA address up to the -IA address plus -IM size overlap the 4 GiByte address minus -BH size up to the 4 GiByte address. The -BH size may be set to 0 (or not specified) if the computer has significantly less than 4 GiBytes of memory.

On computers with Intel vPro Technology, computer memory between the 768 MiByte and 1024 MiByte addresses may be reserved; the -IA address should not be lower than the 1024 MiByte address.
Restart Windows, using the newly added boot selection. Note that using Windows' Shutdown instead of Restart may delay Windows' recognition of these changes until the second subsequent shutdown!

For example, for a computer with 1 GiByte of memory, allocating 256 MiByte for Windows and the remainder for frame buffer memory, use:

    BCDEDIT /set NEW_ENTRY_ID truncatememory 268435456

and use:

    PIXCI = -IA 262144 -IM 786432 -MB 8192

in the registry entry. Note that 262144 is 256×1024, and 786432 is (1024-256)×1024.

Note that if this memory allocation method is used, program access to image data may be slower. Thus, the video display rate (and image processing) may be slower, but the video capture rate (such as sequence capture) is not adversely affected. This method of memory allocation is primarily used for video rate acquisition of long sequences, followed by off-line analysis or saving of the sequence.

3.2.4. Windows 8/10/11 32/64-Bit - Authorization Key - Manual Installation

The default installation directory is nominally C:\Program Files\EPIX\XCAP, or C:\Program Files(x86)\EPIX\XCAP for installation of 32-bit XCAP on 64-bit Windows, but depends on the current Windows' CSIDL settings.
2. If XCAP is provided via the internet:
  1. Download:
```
ftp.epixinc.com/software/xcap_v38/XCAPWIN32.EXE (for 32-bit XCAP for Windows)
```
    or
```
ftp.epixinc.com/software/xcap_v38/XCAPWIN64.EXE (for 64-bit XCAP for Windows)
```
    from the EPIX, Inc. ftp site.
  2. Execute the downloaded program, from a Command Prompt (i.e. Windows Terminal), or via the Windows ''Start'', ''Run'':
```
> XCAPWIN32.EXE     (for 32-bit XCAP for Windows)
```
    or
```
> XCAPWIN64.EXE     (for 64-bit XCAP for Windows)
```
  3. Follow the installation program's directions, such as to select an installation directory. The default installation directory is nominally C:\Program Files\EPIX\XCAP, or C:\Program Files(x86)\EPIX\XCAP for installation of 32-bit XCAP on 64-bit Windows, but depends on the current Windows' CSIDL settings.
  4. The downloaded .EXE file may be deleted.
3. The installation procedure creates a new program group, containing XCAP and several .TXT files. The *.TXT files contain these installation instructions, a list of distributed files, corrections or additions to this manual, or other up-to-date information. The PCITIPS.TXT file provides the PCI Configuration Tips, with tips for resolving hardware and software conflicts. The installation procedure also, optionally, creates a desktop shortcut for XCAP.
Install Authorization Key (for XCAP-Plus, XCAP-Std, and XCAP-Ltd):
1. XCAP-Plus, XCAP-Std, and XCAP-Ltd are provided with an USB authorization key. XCAP-Lite is provided with a software Activation ID Code.
  The Blue (older) or Green (newer) authorization USB key has the size and shape of a USB thumb drive (4 to 6&times1.6×0.8 cm) with a standard USB-A 4-pin connector. If provided, connect the authorization key to a USB port.
  
  The authorization key must remain attached, to the USB port while XCAP is running. If the authorization key is missing, or disconnected while XCAP is running, then XCAP-Plus, XCAP-Std or XCAP-Ltd, will behave similar to the XCAP-Lite version; selected image processing and analysis tools will not be operational.
2. Upon first use, XCAP will prompt for configuration as per the authorization key (including installation of drivers), or the software Activation ID Code.
  Subsequently, use Change Setup under Utility, Program Setup within XCAP, to change XCAP's configuration as per the authorization key or the software Activation ID Code.
Install PIXCI® Frame Grabber Driver:
1. The PIXCI® frame grabber's driver may be installed in response to the Windows Device Manager's prompts (it will prompt once after detecting a newly installed card) and pointing the Device Manager to Drivers\Win7 for Windows 7 32-Bit or Drivers\Win7x64 for Windows 7 64-Bit within the chosen installation directory, or may be installed during XCAP's installation (such as via the XCAPWIN32.EXE or XCAPWIN64.EXE installer), or may be installed by the Driver Assistant feature within XCAP.
  Alternately, the PIXCI® frame grabber's driver can be installed as follows.
2. Open the Windows Device Manager by clicking ''Start'', ''Control Panel'', ''System & Security'', ''System'', and ''Device Manager''. In the Device Manager look for an entry with a yellow exclamation mark that is labeled ''Multimedia Controller'' or ''Coprocessor''. Double-click on the entry and then click the ''Update Driver...'' button. In the ''Update Driver Software'' window that pops-up, select ''Browse my computer for driver software''; in the ''Search for driver software in this location'' enter path Drivers\Win7 for Windows 7 32-Bit, or Drivers\Win7x64 for Windows 7 64-Bit, within the chosen installation directory (typically C:\XCAP or C:\Program Files\EPIX\XCAP), and click ''Next''. A window asks ''Would you like to install this device software?''; click ''Install''. A window reports ''The software for this device has been successfully installed'' and ''The hardware you installed will not work until you restart your computer''; click ''Finish'' and restart Windows.
3. Alternately, using the Windows Explorer, highlight Drivers\Win7\EPIXXCW2.INF for Windows 7 32-Bit or Drivers\Win7x64\EPIXXCW6.INF for Windows 7 64-Bit within the chosen installation directory, right-click and select ''Install'', and restart Windows.
Restart Windows.
XCAP is now ready to run, by clicking the optional shortcut, or by clicking ''Start'', ''Programs'', ''XCAP Imaging'', and finally ''XCAP for Windows''.

3.4. Windows 7 32/64-Bit Esoterica

3.4.1. Windows 7 32/64-Bit - Frame Grabber Driver Installation Details

The PIXCI® frame grabber's driver consists of files:

    EPIXXCW2.INF
    EPIXXCW2.CAT
    EPIXXCW2.SYS

for Windows 7 32-Bit, or files:

    EPIXXCW6.INF
    EPIXXCW6.CAT
    EPIXXCW6.SYS

for Windows 7 64-Bit. Driver files for different versions of Windows, although with the same file name, may have different digital signatures as required by each version of Windows.

The PIXCI® frame grabber driver is installed by the Windows Device Manager, or by Driver Assistant within XCAP.

Installation copies the driver files and creates registry entry:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW2

for Windows 7 32-Bit, or

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW6

for Windows 7 64-Bit. Most values within the registry entry are set by the Device Manager and should not be modified. The value:

    PIXCI   =  -IM <memorysize>  ...

3.4.2. Windows 7 32/64-Bit - Frame Buffer Memory Allocation

Under Windows 7 32/64-Bit, frame buffer memory must be allocated during Windows' initialization.

The requested frame buffer memory size must be specified in the Registry entry described above, using an entry named ''PIXCI'', such as:

    PIXCI         =  "-IM <memorysize>"

Optionally,

    "-MB <memory_partition_size>"

specifies that the requested

    "-IM <memorysize>"

Windows 7 32/64-Bit limits the maximum amount of allocatable frame buffer memory, dependent upon what other devices are installed, the total computer memory size, and other factors. Under Windows 7 32-Bit, the amount of memory that Windows may grant during startup is typically limited to 1024 MiByte, but not more than half of the computer memory size. Under Windows 7 64-Bit, the amount of memory that Windows may grant during startup has not yet been determined, but is probably similar to the limit for Windows Vista 64-Bit: the smaller of 6 GiByte or one half of the computer memory size.

3.4.3. Windows 7 32/64-Bit - Forceful Frame Buffer Memory Allocation

As described above, frame buffer memory allocated by EPIXXCW2.SYS for Windows 7 32-Bit, or EPIXXCW6.SYS for Windows 7 64-Bit, during Windows startup may be limited to a small percentage of total computer memory. Under Windows 7 32-Bit, the amount of memory that Windows may grant during startup is typically limited to 1024 MiByte, but not more than half of the computer memory size. Under Windows 7 64-Bit, the amount of memory that Windows may grant during startup has not yet been determined, but is probably similar to the limit for Windows Vista 64-Bit: the smaller of 6 GiByte or one half of the computer memory size. Some computer and/or Windows configurations may have lower limits.

A larger frame buffer memory can be obtained by limiting the amount of memory recognized by Windows, and then instructing EPIXXCW2.SYS for Windows 7 32-Bit, or EPIXXCW6.SYS for Windows 7 64-Bit, to explicitly use a section of memory without allocating it from Windows.

Use the Windows' BCDEDIT utility to create a copy of the ''{CURRENT}'' boot entry, set the new entry use limit memory usage via ''truncatememory'', and changing the new entry's description.
Typical commands are:
```
    BCDEDIT  /enum
```
to list current entries and obtain the current entry's description,
```
    BCDEDIT  /copy  {current}  /d  "CURRENT_ENTRY_DESCRIPTION [PIXCI=##M NT=##M"
```
to create a new entry with modified description and boot prompt including a reminder of the amount of memory provided to Windows and to the PIXCI® imaging card,
```
    BCDEDIT /enum  /v
```
to get the ID of the new entry, and:
```
    BCDEDIT /set <new_entry_id> truncatememory <memory_size>
```
to limit the Windows memory size to <memory_size>, in bytes.
Also using BCDEDIT change the timeout selection to be greater than 0:
```
    BCDEDIT /timeout 30
```
Otherwise the boot configuration options will not be shown when Windows starts.
Edit the registry entry:
```
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW2
```
for Windows 7 32-Bit, or
```
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW6
```
for Windows 7 64-Bit. On the ''PIXCI'' field add:
```
    -IA <image_memory_adrs_in_KiByte>
    -IM <size_of_image_memory_in_KiByte>
    -MB <image_memory_partition_size_in_KiByte>
    -BH <size_of_BIOS_hole_below_4GiB_in_KiByte>
```
In practice, all four fields are on the same line.
The -MB partition size specifies the size into which image memory is partitioned for the sake of virtual memory management: (a) Each frame buffer must be completely contained within a partition, (b) A value of 0 specifies that the entire image memory is to be handled as one partition, and (c) The maximum number of partitions is 256 under 32 bit operating systems, the maximum number of partitions is 256 under 64 bit operating systems. For most systems, a value of 8192 or 16384 is suggested; though the value need not be a power of two. Systems with very high resolution cameras using large frame buffers should choose the partition size carefully, so as to minimize the unusable memory remaining, smaller than a frame buffer, at the end of each partition.

When using more than 1 or 2 GiBytes of image memory, it may be necessary to append:
```
    -MU 0x01
```
to the ''PIXCI'' field, conserving system memory mapping resources by not mapping the image memory directly into the application program's space. It may also be necessary to append:
```
    -MU 0x03
```
which additionally conserves system resources by mapping memory only on demand.
Be careful that the -IA address is equal to (or above) the specified ''truncatememory'' limit - including exact base2 to base10 conversions! Likewise, be certain that the -IA plus -IM values do not exceed the amount of memory available!

On a computer populated with 4 or more GiBytes of memory, some of the memory directly below the 4 GiByte address overlaps other hardware resources such as BIOS, memory mapped I/O, PCI configuration space, etc.^[2] and is unavailable to either the operating system or for use as frame buffers. The usable frame buffer memory is therefore reduced by the amount by which the -IA address up to the -IA address plus -IM size overlap the 4 GiByte address minus -BH size up to the 4 GiByte address. The -BH size may be set to 0 (or not specified) if the computer has significantly less than 4 GiBytes of memory.

On computers with Intel vPro Technology, computer memory between the 768 MiByte and 1024 MiByte addresses may be reserved; the -IA address should not be lower than the 1024 MiByte address.
Restart Windows, using the newly added boot selection.

For example, for a computer with 1 GiByte of memory, allocating 256 MiByte for Windows and the remainder for frame buffer memory, use:

    BCDEDIT /set NEW_ENTRY_ID truncatememory 268435456

and use:

    PIXCI = -IA 262144 -IM 786432 -MB 8192

in the registry entry. Note that 262144 is 256×1024, and 786432 is (1024-256)×1024.

Install Authorization Key (for XCAP-Plus, XCAP-Std, and XCAP-Ltd):
1. XCAP-Plus, XCAP-Std, and XCAP-Ltd are provided with a printer port authorization key or an USB authorization key. XCAP-Lite is provided with a software Activation ID Code.
  The printer port authorization key is black and approximately the size and shape of a printer's parallel port connector (5.5×4.5×1.6 cm), but with two 25-pin connectors. If provided, connect the authorization key to any printer port. If a printer cable was attached to the printer port, reconnect the printer cable to the back of the authorization key; the authorization key will not affect normal printer operation.
  
  Do not connect the printer port authorization key to a 25-pin serial (RS-232) port, or to any other interface that happens to use the same style connector; the authorization key will not function, might be permanently damaged, and the warranty will be void!
  
  The Blue (older) or Green (newer) authorization USB key has the size and shape of a USB thumb drive (4 to 6&times1.6×0.8 cm), with a standard USB-A 4-pin connector. If provided, connect the authorization key to a USB port.
  
  The authorization key must remain attached, to the printer port or USB port as appropriate, while XCAP is running. If the authorization key is missing, or disconnected while XCAP is running, then XCAP-Plus, XCAP-Std or XCAP-Ltd, will behave similar to the XCAP-Lite version; selected image processing and analysis tools will not be operational.
  
  XCAP and its printer port authorization key is supported on Intel i386 platforms. XCAP and its Blue USB authorization key is supported on Intel i386 and x86-64 platforms. XCAP and its Green USB authorization key are supported on Intel i386 and x86-64 platforms as well as ARM aarch64 and armv7l platforms.
2. Upon first use, XCAP will prompt for configuration as per the authorization key (including installation of drivers), or the software Activation ID Code.
  Subsequently, use Change Setup under Utility, Program Setup within XCAP, to change XCAP's configuration as per the authorization key or the software Activation ID Code.
Install PIXCI® Frame Grabber Driver:
1. The Driver Assistant within XCAP, provides convenient installation of the PIXCI® driver.
Configure Graphics Display:
1. Configuring the graphics display to TrueColor or DirectColor modes (using XWindows terminology), or to 24 or 32 bit modes (using graphic display hardware terminology) is suggested for higher quality, and quicker display of images and overlay graphics.
  Within XCAP, the current graphics display configuration can be checked under Utility, Linux Info, X11.
XCAP is now ready to run, by executing^[3] ''xcap'', or by clicking the optional shortcut.

3.7. Linux Esoterica

3.7.1. Linux 2.6.x, 3.x, 4.x, 5.x - Manual Installation

Use of the Driver Assistant within XCAP provides convenient installation of the:

pixci_i386.ko        (32 bit driver for Intel i386)
pixci_x86_64.ko      (64 bit driver for Intel x86-64
pixci_armv7l.ko      (32 bit driver for ARM armv7l)
pixci_aarch64.ko     (64 bit driver for ARM aarch64)

drivers in most circumstances. The following information allows manual installation, correcting problems, or integration with an OEM's procedures.

Use pixci.sh (and the pixci.rc implied by pixci.sh) files to install the required pixci_i386.ko, pixci_x86_64.ko, pixci_armv7l.ko, or pixci_aarch64.ko driver, configuring Linux to automatically load the driver upon execution and during subsequent reboots:
```
    pixci.sh install
             <absolute path of directory containing pixci.rc>
             <absolute path of directory containing pixci*.ko>
```
The pixci.rc loads pixci_i386.ko, pixci_x86_64.ko, pixci_armv7l.ko, or pixci_aarch64.ko with Driver Configuration Parameters taken from /etc/default/pixci (re-read each time the driver is loaded).
Optionally, for Linux ''tty'' style access to the serial ports of Camera Link compatible PIXCI® cards from third party applications, the pixcitty_i386.ko, pixcitty_x86_64.ko, pixcitty_armv7l.ko, or pixcitty_aarch64.ko drivers can be installed with:
```
    pixcitty.sh install
                <absolute path of directory containing pixcitty.rc>
                <absolute path of directory containing pixcitty*.ko>
```
and its implied pixcitty.rc.
The optional pixcitty_*.ko is NOT needed for access to the Camera Link serial port via XCLIB's proprietary API, nor is it needed by XCAP.
Optionally, for Linux ''Video for Linux (V4L2)'' style access to the video from third party applications, the pixciv4l_i386.ko, pixciv4l_x86_64.ko, pixciv4l_armv7l.ko, or pixciv4l_aarch64.ko drivers can be installed with:
```
    pixciv4l.sh install
                <absolute path of directory containing pixciv4l.rc>
                <absolute path of directory containing pixciv4l*.ko>
```
and its implied pixciv4l.rc, with ''V4L2'' configuration parameters taken from /etc/default/pixciv4l (re-read each time the driver is loaded).
The optional pixciv4l_*.ko is NOT needed for access to captured images or video via XCLIB's proprietary API, nor is it needed by XCAP.

In some circumstances, it may be necessary to avoid use of pixci.sh and pixci.rc (and the implied use of Linux' /etc/rc for automatically loading of drivers during boot), and instead manually load the driver when needed.

Run, as appropriate:

insmod pixci_i386.ko    [ "PIXCIPARM=<driver_config_parameters>" ]
insmod pixci_x86_64.ko  [ "PIXCIPARM=<driver_config_parameters>" ]
insmod pixci_armv7l.ko  [ "PIXCIPARM=<driver_config_parameters>" ]
insmod pixci_aarch64.ko [ "PIXCIPARM=<driver_config_parameters>" ]

using PIXCIPARM= to specify any optional Driver Configuration Parameters described below. For example:

insmod pixci_i386.ko    "PIXCIPARM=-IM 8192 -DM 1"
insmod pixci_x86_64.ko  "PIXCIPARM=-IM 8192 -DM 1"
insmod pixci_armv7l.ko  "PIXCIPARM=-IM 8192 -DM 1"
insmod pixci_aarch64.ko "PIXCIPARM=-IM 8192 -DM 1"

Some versions of insmod do not accept quoted spaces in the Driver Configuration Parameters; an underscore (i.e. ''_'') may be used instead of a space. For example:

insmod pixci_i386.ko PIXCIPARM=-IM_8192_-DM_1

To use the Driver Configuration Parameters as last set by XCAP's Driver Assistant and stored in /etc/default/pixci:

    insmod pixci_i386.ko PIXCIPARM=$(grep pixci.driver.parm= < /etc/default/pixci | sed -e "s/driver.pixci.parm=//"  -e "y/ \\\/__/")

Run:

    cat /proc/devices

and note the major device number which is assigned to the pixci block device. Run:

    rm -f /dev/pixci
    mknod /dev/pixci c <major_device_number> 0
    chmod 666 /dev/pixci

If embedding these commands into a shell script:

    rm -f /dev/pixci
    mknod /dev/pixci c $(awk "\\$2==\"PIXCI(R)\" {print \\$1}" /proc/devices) 0
    chmod 666 /dev/pixci

automatically ''reads'' and incorporates the major device number.

Optionally, for Linux ''tty'' style access to the serial ports of Camera Link compatible PIXCI® cards run, as appropriate:
```
insmod pixcitty_i386.ko      [ <tty_config_parameters> ]
insmod pixcitty_x86_64.ko    [ <tty_config_parameters> ]
insmod pixcitty_armv7l.ko    [ <tty_config_parameters> ]
insmod pixcitty_aarch64.ko   [ <tty_config_parameters> ]
```
The
```
    /dev/ttySPIXCI0
    /dev/ttySPIXCI1
    ...
```
nodes for the first, second, etc. cards are created automatically.
The ''tty'' configuration parameters are described in pixcitty.df. For example:
```
insmod pixcitty_i386.ko      DEFAULT_BAUDRATE=9600
insmod pixcitty_x86_64.ko    DEFAULT_BAUDRATE=9600
insmod pixcitty_armv7l.ko    DEFAULT_BAUDRATE=9600
insmod pixcitty_aarch64.ko   DEFAULT_BAUDRATE=9600
```
The optional pixcitty_*.ko driver is used in addition to, and installed after, the corresponding pixci_*.ko driver. The optional pixcitty_*.ko is NOT needed for access to the Camera Link serial port via XCLIB's proprietary API, nor is it needed by XCAP.
Optionally, for ''Video for Linux (V4L2)'' style access to the video from third party applications, run, as appropriate:
```
insmod pixciv4l_i386.ko      [ <v4l_config_parameters> ]
insmod pixciv4l_x86_64.ko    [ <v4l_config_parameters> ]
insmod pixciv4l_armv7l.ko    [ <v4l_config_parameters> ]
insmod pixciv4l_aarch64.ko   [ <v4l_config_parameters> ]
```
The:
```
    /dev/video*
    ...
```
nodes for the first, second, etc. cards are created automatically.
The ''V4L2'' configuration parameters are described in pixciv4l.df. For example:
```
insmod pixciv4l_i386.ko      STREAM_MODE=1  STREAM_BUFFERS=12
insmod pixciv4l_x86_64.ko    STREAM_MODE=1  STREAM_BUFFERS=12
insmod pixciv4l_armv7l.ko    STREAM_MODE=1  STREAM_BUFFERS=12
insmod pixciv4l_aarch64.ko   STREAM_MODE=1  STREAM_BUFFERS=12
```
The optional pixciv4l_*.ko driver is used in addition to, and installed after, the corresponding pixci_*.ko driver. The optional pixciv4l_*.ko is NOT needed for access to captured images or video via XCLIB's proprietary API, nor is it needed by XCAP.
For PIXCI® SV2, SV3, SV4, SV5, SV5A, SV5B, and SV5L frame grabbers, drivers other than those provided by EPIX, Inc. may have been installed during Linux's configuration. See http://will.freehosting.net/bttv-HOWTO.html, section 5.1 for information on removing the drivers. In brief, use:
```
    lsmod
```
for a list of currently installed modules and remove any named videodev, i2c, i2c-char, tuner, msp3400, bt878, or bttv by using rmmod.

3.7.2. Linux 3.x, 4.x, 5.x - Frame Buffer Memory Allocation

Under Linux, frame buffer memory must be allocated during the driver's installation.

The requested frame buffer memory size must be specified in the Driver Configuration Parameters, described above, using parameter

    "-IM <memorysize>"

replacing the ''<memorysize>'' with the desired memory size in KiBytes. If no frame buffer memory size is specified, a default size of 4096 KiBytes is used under 32 bit Linux. 32768 KiBytes is used under 64 bit Linux.

Optionally,

    "-MB <memory_partition_size>"

specifies that the requested

    "-IM <memorysize>"

Linux limits the maximum amount of allocatable frame buffer memory, dependent upon what other devices are installed, the computer's total memory size, and other factors. Installing the driver immediately after booting Linux improves the likelihood of being able to allocate large amounts of memory.

Linux may provide less frame buffer memory than was requested. If no memory could be allocated, the PIXCI® frame grabber will not be available, stating ''Can't allocate frame buffer memory''. Otherwise, within XCAP, the number of available frame buffers can be checked under PIXCI®, PIXCI® Video Setup, Resolution. As the frame buffer memory is allocated once during the driver's initialization; the contents of frame buffers are retained as XCAP is closed and restarted, but lost if the driver is uninstalled or Linux is restarted.

For the nVidia TK1 (ARM Cortex-A15), the nVidia TX1/TX2 (ARM Cortex-A57), the nVidia Nano (ARM Cortex-A57) and the Boundary Devices NITROGEN6 (ARM imx6) (but not the nVidia Xavier or Xavier NX), the amount of frame buffer memory that can be allocated is limited by the kernel's ''coherent pool'' size. For these embedded systems, the memory is split into various special purpose pools - unlike a typical desktop system. For the TK1, TX1, TX2, increasing the ''coherent pool'' size requires editing the /boot/extlinux/extlinux.conf file and setting the ''vmalloc'', ''CMA'', and ''coherent-pool'' parameters. For the NITROGEN6, increasing the ''coherent pool'' size requires editing the /6x_bootscript.txt file and setting the ''coherent-pool'' parameter, followed by compilation of /6x_bootscript.txt via a Boundary Devices tool, and replacement of the /6x_bootscript file. Values for ''coherent-pool'' and other parameters must take into account all devices and requirements of the system.

3.7.3. Linux 2.6.x, 3.x, 4.x, 5.x - Forceful Frame Buffer Memory Allocation

As described above, frame buffer memory allocated by pixci_i386.ko or pixci_x86_64.ko during its installation may be limited to a small percentage of the computer's total memory.

A larger frame buffer memory can be obtained by limiting the amount of memory recognized by Linux, and then instructing pixci_i386.ko or pixci_x86_64.ko to explicitly use a section of memory without allocating it from Linux.

Edit /boot/grub/grub.conf (renamed to /boot/grub/menu.lst on some systems), restricting Linux to use no more than a set amount of memory: by copying an existing configuration group, adding mem=XXM (where XX is the memory size in MiByte) to the ''kernel'' line, and changing the prompt name. For example, changing:
```
    title Fedora Core (2.6.5-1.358)
        root (hd0,0)
        kernel /vmlinuz-2.6.5-1.358 ro root=LABEL=/ rhgb quiet
        initrd /initrd-2.6.5-1.358.img
```
to
```
    title Fedora Core (2.6.5-1.358) + PIXCI
        root (hd0,0)
        kernel /vmlinuz-2.6.5-1.358 ro root=LABEL=/ rhgb quiet mem=64M
        initrd /initrd-2.6.5-1.358.img
```
When booting, the modified ''title'' provides a reminder of the modified configuration being selected.
Change the Driver Configuration Parameters. Add:
```
    -IA <image_memory_adrs_in_KiByte>
    -IM <size_of_image_memory_in_KiByte>
    -MB <image_memory_partition_size_in_KiByte>
    -BH <size_of_BIOS_hole_below_4GiB_in_KiByte>
```
In practice, all four fields are on the same line.
The -MB partition size specifies the size into which image memory is partitioned for the sake of virtual memory management: (a) Each frame buffer must be completely contained within a partition, (b) A value of 0 specifies that the entire image memory is to be handled as one partition, and (c) The maximum number of partitions is 256 under 32 bit operating systems, the maximum number of partitions is 256 under 64 bit operating systems. For most systems, a value of 8192 or 16384 is suggested; though the value need not be a power of two. Systems with very high resolution cameras using large frame buffers should choose the partition size carefully, so as to minimize the unusable memory remaining, smaller than a frame buffer, at the end of each partition.

Be careful that the -IA address is equal to (or above) the specified ''mem='' limit - including exact base2 to base10 conversions! (i.e. for mem=64M, the smallest valid value of -IA is 65536, not 64000!). Likewise, be certain that the -IA plus -IM values do not exceed the amount of memory available!

On a computer populated with 4 or more GiBytes of memory, some of the memory directly below the 4 GiByte address overlaps other hardware resources such as BIOS, memory mapped I/O, PCI configuration space, etc.^[4] and is unavailable to either the operating system or for use as frame buffers. The usable frame buffer memory is therefore reduced by the amount by which the -IA address up to the -IA address plus -IM size overlap the 4 GiByte address minus -BH size up to the 4 GiByte address. The -BH size may be set to 0 (or not specified) if the computer has significantly less than 4 GiBytes of memory.

On computers with Intel vPro Technology, computer memory between the 768 MiByte and 1024 MiByte addresses may be reserved; the -IA address should not be lower than the 1024 MiByte address.
Reboot, using the newly added configuration.

For example, for a computer with 1 GiByte of memory, allocating 256 MiByte for Linux and the remainder for frame buffer memory, use:

    mem=256M

in grub.conf (or menu.lst), and use:

    -IA 262144 -IM 786432 -MB 8192

in the Driver Configuration Parameters. Note that 262144 is 256×1024, and 786432 is (1024-256)×1024.

Forceful frame buffer memory allocation is not available for pixci_aarch64.ko on the nVidia/ARM TX/TX21/Cortex-A57.

Forceful frame buffer memory allocation is not available for pixci_armv7l.ko on the nVidia/ARM TK1/Cortex-A15.

Forceful frame buffer memory allocation is not available for pixci_armv7l.ko on the Boundary Devices/ARM NITROGEN6/imx6.

3.7.4. Linux 2.6.x, 3.x, 4.x, 5.x - Authorization Key - Manual Installation

Use of the Driver Assistant within XCAP, provides convenient installation of the authorization key's driver(s).

The following information allows manual installation, correcting problems, or integration with an OEM's procedures.

3.7.4.1. Printer Port and USB Blue Authorization Keys

For manual installation, correcting problems, or integration with an OEM's procedures, installation instructions are provided in text file hardlock/INSTALL within the XCAP installation directory. Alternately, see the hardlock/drv/src_i386/Makefile for compiling the parallel port key driver under the current kernel, the hardlock/drv/pinst shell file for installing the parallel port key driver, and the hardlock/sbin/dinst shell file for installing the USB key daemon, all within the XCAP installation directory.

The parallel port key driver is needed under 2.4.x, 2.6.x, 3.x, 4.x, and 5.x i386 kernels even if the parallel port version of the key isn't used. Parallel port keys are not supported under newer x86-64 kernels; the hardlock/drv/src_x86_64/Makefile and related files are provided for legacy systems.

The printer port and Blue USB authorization key and drivers are not supported on ARM platforms.

3.7.4.2. USB Authorization Green Keys

From the XCAP chosen installation directory:

    > /usr/local/xcap

copy the:

    keylok/i386/z95_keylok.rules

or:

    keylok/x86_64/z95_keylok.rules

file to:

    /etc/udev/rules.d/

Or, execute:

    keylok/klinst keylok/i386

    keylok/klinst keylok/x86_64

Reboot Linux.

3.8. For older versions of Linux

See the XCAP Reference Manual for detailed installation instructions.

3.9. PIXCI® Driver Esoterica

The various Driver Configuration Parameters for all operating systems are summarized below.

The Driver Configuration Parameter string may contain any of the following parameters, separated by spaces, in any order. Each parameter's flag is followed by a number, whose value is interpreted as hexadecimal if preceded by ''0x'' or ''0X'', octal if preceded by ''0o'' or ''0O'', binary if preceded by ''0b'' or ''0B'', and is otherwise interpreted as decimal.

-BH n

If n≠0, the amount of memory space, in KiByte, directly below the 4 GiByte address which overlaps other hardware resources such as BIOS, memory mapped I/O, PCI configuration space, etc. and is unavailable to either the operating system or for use as frame buffers.^[5] The usable frame buffer memory is therefore reduced by the amount by which the -IA address up to the -IA address plus -IM size overlap the 4 GiByte address minus -BH size up to the 4 GiByte address. Only used with forceful image frame buffer allocation, under Windows NT, 2000, XP, XP(x64), Vista 32/64-Bit, 7 32/64-Bit, 8/10 32/64-Bit, 11 64-Bit, Linux 32 Bit, and Linux 64 Bit. Default: 0.

-BS n

If n≠0, per-frame buffer capture status is maintained. If n=0, per-frame buffer capture status is not maintained. Also see the -MU parameter. Default: 1.

-CL n

If bit 0x01 is set, Power over Camera Link (PoCL) is maintained after the PIXCI® frame grabber is closed and later reopened by software. Only selected versions of Camera Link PIXCI® frame grabbers support PoCL; older versions apply PoCL whenever the frame grabber is powered on; newer versions disable PoCL when the PIXCI® frame grabber is closed by software - subject to this option. Setting bit 0x01 will also disable running of ''data path'' startup diagnostics. Default: 0.

-CQ n

Size of queue for video capture enqueue/capture/dequeue services, i.e. pxd_quSnap and pxd_quLive. Queue size is low 10 bits of value (i.e. 0 through 1023) plus, if bit 0x8000 set, the current number of frame buffers (as per the size of frame buffer memory versus the current video resolution). The requested value is forced to the next highest power of 2 and forced to be no smaller than 2; however this behavior is subject to change. Under Windows 95, 98, and ME, the maximum value is 2. Default: 0.

-DM n

A bit map selecting which of the PIXCI® frame grabbers present should be used. The i'th bit of the bit-map selects the i'th board found, sequentially, on the PCI, PCIe, or ExpressCard bus(es). The relationship between bit i and the order of motherboard slots is motherboard, BIOS, and OS dependent and can not be specified or queried via XCAP.

For example, 0x01 selects the first board, 0x04 selects the third board, and 0b1001 selects the first and fourth board.

For the PIXCI® E1DB, E4DB, E4G2-2F, E4TX2-2F, E8CAM, E8DB, e104x4-2f, ECB2, EL1DB, ELS2, SI2, and SV7 frame grabbers which contain two independent functional units within a single physical board, and for the PIXCI® E4G2-F2B, E4TX2-F2B, and e104x4-f2b frame grabbers which contains three independent functional units within a single physical board, and for the PIXCI® E4G2-4B, E4TX2-4B, e104x4-4b, and SI4 frame grabbers which contain four independent functional units within a single physical board: Under Windows 2000, XP, XP(x64), Vista 32/64-Bit, 7 32/64-Bit, 8/10 32/64-Bit, 11 64-Bit, Linux 32 Bit, and Linux 64 Bit, each functional unit is handled as an independent frame grabber and may be opened and closed independently. Under other operating systems, the first functional unit (i.e. half, third, or quarter) must be opened before latter functional units of the same physical board. A bit map of 0b1101 selects the first half of the first physical PIXCI® E1DB, E4DB, E4G2-2F, E4TX2-2F, E8CAM, E8DB, e104x4-2f, EL1DB, ECB2, ELS2, SI2, or SV7 frame grabber and both halves of the second physical PIXCI® E1DB, E4DB, E4G2-2F, E4TX2-2F, E8CAM, E8DB, e104x4-2f, EL1DB, ECB2, ELS2, SI2, or SV7; 0b11111001 selects the first and fourth quarter of the first physical PIXCI® E4G2-4B, E4TX2-4B, e104x4-4b, or SI4 frame grabber and all quarters of the second physical PIXCI® E4G2-4B, E4TX2-4B, e104x4-4b, or SI4. Default: 0x01, except under a Windows Plug & Play O.S. where the default is a bitmap of all functional units of the first physical board.

-IA n

If n≠0, the physical address of memory, in KiByte, at which image frame buffers are assumed to start. Only used with forceful image frame buffer allocation, under Windows 95, 98, ME, NT, 2000, XP, XP(x64), Vista 32/64-Bit, 7 32/64-Bit, 8/10 32/64-Bit, 11 64-Bit, Linux 32 Bit, and Linux 64 Bit. Default: 0.

-IM n

Requested size, in KiByte, to be reserved for the entire image frame buffer memory. Default: 32768 KiByte under Windows NT, 2000, XP, Vista 32-Bit, 7 32-Bit, and 8/10 32-Bit, 32768 KiByte under Windows XP(x64), Vista 64-Bit, 7 64-Bit, 8/10 64-Bit, 11 64-Bit, and Linux 64 Bit, 4096 KiByte for others.

For the PIXCI® CL3SD and SI2 which have on-board frame buffer memory, memory reserved by this parameter is needed for DMA buffers (approximately 1 MiByte). Memory reserved by this parameter is also, optionally, used for support of recording per-frame buffer capture status, as specified by the ''-MU'' parameter. Currently, 64 bytes are needed for each frame buffer's capture status. Default: 4096 KiByte.

-I2C n

Bit rate of the I²C or other two wire serial bus used within some PIXCI® frame grabbers. Specifies an upper bound for the bit rate; actual bit rate is dependent on characteristics of the computer system and is typically slower. Value of 0 selects predefined, board-dependent, default values.

Particularly useful for use with SILICON VIDEO® 10C6, 10M6, 1281M, 1281C, 1310, 1310C, 15C5, 1C45, 1M45 2112, 2112C, 2KS-C, 2KS-M, 5C10, 5M10, 642M, 642C, 643M, 643C, 9C10, 9M001, 9M001C, 9T001C, WGA-C, and WGA-M cameras; these SILICON VIDEO® camera heads use a I²C or similar two wire serial bus to control camera head features.

Does not affect the serial baud rate of Camera Link compatible frame grabbers.

Default: 0.

-LX n

If bit 0x20 is set, a high resolution kernel timer (i.e. ''do_gettimeofday'' for earlier kernels or ''getnstimeofday'' for kernel 5.x and later) is used for time stamping video events instead of ''jiffies'' and ''HZ''; however, the high resolution timer incurs additional overhead. Only used with Linux 32 Bit and Linux 64 Bit. The new -.TI option supersedes this option.

If bit 0x80 is set with non forceful memory allocation, frame buffer memory below 4 GiByte is requested; on 64 bit systems with more than 4 GiByte of memory, this allows allows use of 32 bit PCI cards. Option is quietly ignored for kernels that don't support the necessary feature(s).

Only used under Linux. Other bits to be described. Default: 0.

-MB n

If n≠0, the image frame buffer memory, of size specified by ''-IM'', is split into partitions of this size, in KiByte. Depending on operating system and ''-IA'' parameters, this may imply that each partition is individually allocated, so that a larger, total amount of memory can be allocated. Or that the contiguous memory is treated as individual partitions for the sake of the operating system and processor's virtual memory management, which could not otherwise ''map'' the entire frame buffer memory at once. In either case, (a) A single frame buffer can't extend across partitions, (b) The partition size should be a multiple of the frame buffer size so as to maximize the number of buffers and minimize wasted space, and (c) A maximum of 256 partitions is supported under 32 bit operating systems, a maximum of 256 partitions is supported under 64 bit operating systems. Default: 0.

-MH n

If n≠0, the amount of lower memory, in KiByte, to pass over before allocating the requested image frame buffer memory. This may be necessary for use with some graphics display or network interface cards which, a) May be allocating memory later than the PIXCI® driver, and b) May require memory with lower addresses. Only used with non-forceful image frame buffer allocation, under Windows NT, 2000, XP, XP(x64), Vista 32/64-Bit, 7 32/64-Bit, 8/10 32/64-Bit, and 11 64-Bit. Default: 0 KiByte under Windows NT, 2000, XP, Vista 32-Bit, 7 32-Bit, and 8/10 32-Bit; 512 KiByte under Windows XP(x64), Vista 64-Bit, 7 64-Bit, 8/10 64-Bit, and 11 64-Bit.

-MO n

Reserved for future use. Default: 0.

-MU n

If bit 0x01 is not set, the frame buffer memory is not mapped directly into the application's address space. If bit 0x02 is set, the frame buffer memory is not permanently mapped into the driver's address space. These options minimize use of the operating systems memory management resources, but may increase overhead in accessing frame buffer memory. These options are typically required when using very large amounts of frame buffer memory (typically, more than 1 or 2 GiByte under Windows NT, 2000, XP, Windows NT, 2000, XP, XP(x64), Vista 32/64-Bit, 7 32/64-Bit, 8/10 32/64-Bit, and 11 64-Bit or more than a few hundred MiByte under Windows 95/98/ME), but are not currently supported for all Video Format Configurations.

If bit 0x04 is not set, the frame buffer memory is not cleared after allocation, minimizing delay, particularly when using several GiBytes of frame buffer memory.

If bit 0x08 is not set, a portion of frame buffer memory is reserved for recording each per-frame buffer's capture status, such as stamping the time of capture. Use of frame buffer memory for capture status may not be supported when using forceful image frame buffer allocation. If bit 0x08 is set, memory is allocated dynamically from the operating system for recording each frame buffer's capture status. The amount of space reserved, or the amount of space allocated, is proportional to the number of frame buffers. The dynamic memory allocation option is not available under Windows 95, 98, or ME; and the per-frame buffer status is discarded upon closing the PIXCI® frame grabber(s).

If bit 0x20 is not set, a portion of frame buffer memory is reserved for serial data buffers used in conjunction with Camera Link serial communication. (For the PIXCI® CL3SD which has on-board frame buffer memory, a small static buffer is used in place of frame buffer memory). If bit 0x20 is set, memory is allocated dynamically from the operating system for serial data buffers. The dynamic memory allocation option is not available under Windows 95, 98, or ME.

If bit 0x40 is set, the frame buffer memory and memory used for recording per frame buffer's capture status is cleared (i.e. set to zero) whenever the capture format resolution, bit depth, bit packing, or color space options are changed. This is intended so that display of the contents of the frame buffer(s), under the new format but before a new image is captured, will show a black image (or green for YUYV formats) rather than ''garbled'' pixel data. This option is ignored when using forceful image frame buffer allocation, or for frame grabbers with on-board frame buffer memory.

Default: 0x01 under Windows 95, 98, ME. 0x28 under Linux 32 Bit and Linux 64 Bit prior to kernel 4.x; 0x29 for kernel 4.x and later. 0x29 under Windows NT, 2000, XP, XP(x64), Vista 32/64-Bit, 7 32/64-Bit, 8/10 32/64-Bit, 11 64-Bit.

-PO n

If n≠0, the polling period, in µseconds, for driver features that are not driven by an interrupt. Ignored under Tenberry DOS4GW DOS extender. Default: 5000 µseconds.

-QP n

The XCAP normally installs a bimodal interrupt handler so that XCAP interrupts are handled in both real and protected modes. The Tenberry DOS4GW DOS extender included with Watcom C/C++ does not have all of the features (DPMI services) required by XCAP, the Tenberry DOS4GW Professional DOS extender must be used. Alternately, if n≠0, an assigned auxiliary interrupt number (not IRQ number!) within Tenberry's range of auto pass-up interrupts: 0x08 to 0x2E. Only used with the Tenberry DOS4GW DOS extender. Default: 0.

-QS n

If n≠0, allow sharing the frame grabbers' assigned hardware interrupt with other devices. IRQ sharing is possible problem for cards using the older PCI bus w. IRQ pins, but not for cards using PCI Express and its Message Signaled Interrupts (MSI). Ignored under Tenberry DOS4GW DOS extender. Default: 1.

-QU n

If n≠0, utilize the frame grabbers' hardware interrupts. For PIXCI® A, A110, A310, CL1, CL2, CL3SD, D, D24, D32, D2X, D3X, D3XE, E1, E1DB, E4, E4DB, E4G2-2F, E4G2-4B, E4G2-F2B, E4TX2-2F, E4TX2-4B, E4TX2-F2B, E8, E8CAM, E8DB, e104x4-2f, e104x4-4b, e104x4-f2b, EB1, EB1-PoCL, EB1mini, EC1, ECB1, ECB1-34, ECB2, EL1, EL1DB, ELS2, SI, SI1, SI2, SI4, SV4, SV5, SV5A, SV5B, SV5L, SV7, and SV8 frame grabbers, the interrupt may be disabled if the polling period (-PO) is small relative to a field's period. For PIXCI® SV2 and SV3, disabling the interrupt will adversely affect all capture modes other than snap. For PIXCI® D, D24, and D32, the interrupt may be disabled only if the interrupt is not shared. For all PIXCI® frame grabbers operated under Tenberry DOS4GW DOS extender, use of hardware interrupts is required. Disabling use of interrupts is intended primarily for diagnosing interrupt conflicts, and is not recommended. Default: 1.

-SB n

Size of serial data buffers, in bytes, for PIXCI® frame grabbers supporting Camera Link cameras. Currently, the driver rounds the specified value to a power of 2. Default: 1024 bytes.

-SX n

Serial options, for PIXCI® frame grabbers supporting Camera Link cameras. If bit 0x01 is set, serial framing errors are ignored. Default: 0.

-SM n

Total amount of memory, in KiByte, on the computer system. This parameter and value is currently ignored by the PIXCI® driver, but used by XCAP's Driver Assistant in conjunction with -IM and -IA to note the ''context'' under which the -IM and -IA values were set.

Default: 0.

-XM n

If n≠0, reserve the proportionate share of image frame buffer memory for frame grabbers not opened by the first application, for use with other frame grabbers opened later. If 0, all image frame buffer memory is shared amongst the frame grabbers opened by the first application. Affects PIXCI® frame grabbers other than CL3SD and SI2, which have on-board frame buffer memory. Default: 1.

-SV5 n

Setting bit 0x02 enables compatibility with 430FX PCI controllers. Setting bit 0x04 enables compatibility with VIA/SIS PCI controllers. Only used with PIXCI® SV5, SV5A, SV5B, SV5L. Default: 0.

-TI n

If n=0, time stamping video events is disabled.

Under Linux: If n=1, the ''jiffies'' and ''HZ'' are used for time stamping video events. If n=2, the high resolution kernel timer (i.e. ''do_gettimeofday'' for earlier kernels or ''do_getnstimeofday'' for kernel 5.x and later) is used for time stamping video events. If n=3, the ''get_jiffies_64'' is used for time stamping video events.

Under Windows 95, 98, and ME: If n=1, the ''Get_Last_Updated_System_Time'' is used for time stamping video events.

Under Windows NT: If n=1, the ''KeQuerySystemTime'' is used for time stamping video events.

Under Windows 2000, XP, XP(x64), Vista 32/64-Bit, 7 32/64-Bit: If n=1, the ''KeQuerySystemTime'' is used for time stamping video events. If n=2, the ''KeQueryPerformanceCounter'' is used for time stamping video events. If n=3, the ''KeQueryInterruptTime'' is used for time stamping video events. If n=4, the ''KeQueryTickCount'' is used for time stamping video events.

Under Windows 8/10 32/64-Bit and 11 64-Bit: If n=1, the ''KeQuerySystemTime'' is used for time stamping video events. If n=2, the ''KeQueryPerformanceCounter'' is used for time stamping video events. If n=3, the ''KeQueryInterruptTime'' is used for time stamping video events. If n=4, the ''KeQueryTickCount'' is used for time stamping video events. If n=5, the ''KeQuerySystemTimePrecise'' is used for time stamping video events.

Each option has various advantages and disadvantages, as described by the operating system's documentation. Default: For backward compatibility, time stamping as per -WT or -LX is used.

-WT n

If bits 0x05 are set to 0x01 or to 0x05, alternate methods of Windows NT resource allocation are used, avoiding problems seen on some motherboards where the same resources are assigned to multiple frame grabbers. Only used with Windows NT.

If bit 0x20 is set, a high resolution kernel timer is used for time stamping video events. Windows documentation states that use of this timer incurs additional overhead. Only used with Window NT, 2000, XP, XP(x64), Vista 32/64-Bit, 7 32/64-Bit, 8/10 32/64-Bit, and 11 64-Bit. The new -TI option supersedes this option.

If bit 0x80 is set, frame buffer memory below 4 GiByte is requested; on 64 bit systems with more than 4 GiByte of memory, this allows allows use of 32 bit PCI cards, and/or allows allows use of 32 bit applications. Only used with Window XP, XP(x64), Vista 64-Bit, 7 64-Bit, 8/10 64-Bit, and 11 64-Bit.

if bit 0x100 is set, the driver applies a patch so that the frame grabber can be opened after Windows awakes from sleep or hibernation modes. Only used with Vista 32/64-Bit, 7 32/64-Bit, 8/10 32/64-Bit, and 11 64-Bit.

If bit 0x200 is set, the driver does not use IOCTL ''DIRECT'' mode.

If bit 0x1000 is set, the driver implements a work-around so that Windows sleep or hibernation does not adversely affect the operation of older PIXCI® frame grabbers

Only used under Windows. Other bits to be described. Default: 0x20.

4. Getting Started with XCAP

This chapter will guide the user through the initial steps common to most applications using the PIXCI® frame grabber: capturing, viewing, examining, and saving images. This guide is not intended to discuss every feature of every window in XCAP, only the most important features to ''get up and running''.

Following the previous instructions:

The PIXCI® frame grabber has been installed.
The camera has been connected to the PIXCI® frame grabber.
The XCAP software has been installed.
For XCAP-Plus, XCAP-Std, or XCAP-Ltd, but not XCAP-Lite or XCAP-Viewer, the authorization key has been installed on a USB port, or, for older systems, installed on the parallel port.
Under Windows, the graphics display has been set for 16 bits (minimum required), or 24 or 32 bits (preferred), per pixel. Under Linux, the graphics display has been set to DirectColor or TrueColor.
The PIXCI® driver for current version of Windows or Linux has been installed.
The computer has been rebooted so that the installed driver and the modified graphics display settings (if any) have taken effect.

4.1. Start XCAP

Under Windows, start XCAP by clicking:

    Start (on the Windows Taskbar)
    All Programs (skip for Windows Vista & earlier)
    XCAP Imaging
    XCAP for Windows

Under Linux, start XCAP by executing:

    xcap

Or, start XCAP via its desktop shortcut.

The XCAP Main Window appears.

4.2. Open PIXCI® Frame Grabber

XCAP is normally configured to automatically open the PIXCI® frame grabber for use and show the PIXCI® Image Viewer window.

Alternately, in the XCAP Main Window, click:

    PIXCI®
    PIXCI® Open/Close

A dialog window appears.

Clicking:

    Open

opens the PIXCI® frame grabber for use, removes the Open/Close dialog.

Upon opening selected PIXCI® frame grabbers, XCAP may display a Camera & Format dialog listing various compatible cameras. Simply click:

    .. select camera from list ..
    OK
    Open

Opening the PIXCI® frame grabber creates a PIXCI® Image Viewer window showing the first PIXCI® frame buffer, creates a Capture & Adjust dialog with commonly used video capture adjustments, and creates a Shortcuts Toolbar for accessing the most commonly needed features.

The following windows are now active:

The Main Window, which has options for reconfiguring the PIXCI® frame grabber, and has features independent of the PIXCI® frame grabber, such as loading images into image buffers unrelated to video capture hardware.
The PIXCI® Image Viewer window, from which the PIXCI® frame buffers are captured, viewed, examined, processed, measured, and saved, with a status bar below the image with cursor coordinates, video frame rate, and other information.
The PIXCI® Shortcut Toolbar, with shortcuts for the most commonly needed features relating to the PIXCI® frame grabber and its frame buffers. The Shortcuts may appear within the PIXCI® Image Viewer window, to the left of the image, rather than a separate window.
A Capture & Adjust dialog, with commonly used video capture adjustments.

XCAP may have been configured for one or more variations, such as, (a) Automatically opening, or not opening, the PIXCI® frame grabber and displaying the PIXCI® Image Viewer, (b) Eliminating the Main Window with its menus integrated into the PIXCI® Image Viewer window, (c) Configuring the Shortcuts and/or Capture & Adjust features to be attached to the PIXCI® Image Viewer window rather than detached in their own windows, (d) Selecting whether the Shortcuts and/or Capture & Adjust features appear automatically, or only when:

    Capture
    Shortcuts

    Capture
    Adjustments

are clicked, or (e) Removing the status bar to increase the screen area available for image display. These variations allow custom configuration of XCAP, but do not affect the functionality of the Shortcuts or Adjustments features.

4.3. PIXCI® A310 Video Configuration

The PIXCI® A310 defaults to the RS-170 monochrome video format, capturing full video resolution. These defaults can be adjusted as follows.

4.3.1. Video Format

From the Main window, click:

    PIXCI®
    PIXCI® Video Setup
    Format

Select an alternate video format, and click:

OK

Or, from the Main window, click:

    PIXCI®
    PIXCI® Open/Close
    Close (if open)
    Camera & Format
    .. select video format from list ..
    OK
    Open

4.4. Capturing Images

Once the PIXCI® frame grabber is opened for use, images can be captured from the PIXCI® Image Viewer, by clicking:

    Capture
    Snap

    Capture
    Live

The Snap captures a single image into the current frame buffer, while Live continuously captures images into the current frame buffer and continuously updating the image shown on the graphics display.

The Live mode can be used to adjust the camera's focus, aperture, and position. The Live mode can be halted by clicking:

    Capture
    UnLive

A Live followed immediately by Unlive has the same effect as Snap.

If the current video resolution and frame buffer memory size allows more than one frame buffer, clicking:

    Capture
    Adjustments

provides the:

    Current (Frame) Buffer:   0

which may be incremented or decremented at any time, whether in Live or UnLive mode. The window reached by clicking:

    Capture
    Adjustments

has convenient buttons that duplicate the Snap, Live, and UnLive features.

As three of the most commonly used operations, the Snap, Live, and UnLive are also available in the Shortcuts Toolbar, as two shortcuts with a graphic of camera; one for snap and the other for live/unlive. The Shortcuts also allow changing the current frame buffer, as four shortcuts with the graphic of a book's pages; switch to the first frame buffer, to the next frame buffer (e.g. current buffer +1), to the previous frame buffer (e.g. current buffer -1), and to the last frame buffer. The relative position of these shortcuts changes depending on whether the Shortcuts Toolbar is standalone window or within the PIXCI® Image Viewer window, and depending on the graphic display resolution and size of the windows; hovering the mouse over the shortcuts will explain the use of each.

4.5. Examining Images

4.5.1. Altering How the Image is Displayed

The PIXCI® Image Viewer can be moved and resized, using standard techniques (drag the window's title bar, drag the window's corner, etc). By default, the captured image is displayed with resizing, so that the entire image fits within the Image Viewer.

For many engineering and scientific applications, examination of individual pixel values is critically important. Resizing the image may ''hide'' defective pixels; resizing an image with interlace jitter may turn odd/even line striping into bars of striping.

To view pixels without resizing artifacts, from the PIXCI® Image Viewer, click:

    View
    Display
    Resize: None (Image Pixel = Display Pixel)

Each image pixel is now displayed as exactly one graphics display pixel. Of course, depending upon the image resolution, graphics display resolution, and window size, the entire image may not fit. If the image doesn't fit, then (a) Scroll bars appear, allowing the viewed portion of the image to be panned and scrolled throughout the entire image, and (b) Moving the mouse with right button held over the displayed image causes panning or scrolling (if there is more image to be seen in the direction the mouse is moving).

For high resolution displays and lower resolution images, using:

    Resize: Pixel Replication/Decimation

will provide a more pleasing display; duplicating pixel values to fill the display while still avoiding resizing artifacts.

For cameras that don't have square pixels (i.e. aspect ratio), after selecting:

    Resize: None (Image Pixel = Display Pixel)

    Resize: Pixel Replication/Decimation

the displayed image's aspect ratio may not appear correct; the aspect ratio can't be corrected without some form of resizing or resampling! To display the image with the correct aspect ratio, choose:

    Resize: To Window & Aspect Ratio

4.5.2. Zoom, Mirror, Flip

To magnify the displayed image, from the PIXCI® Image Viewer, click:

    View
    Zoom, Pan, Scroll
    Zoom On

The magnification factor can be adjusted with:

    Zoom Ratio

Or, if

    Zoom Interact

is enabled, magnification can be increased or decreased by clicking on the image. When magnified, only a portion of the image is visible. As described above, the viewed portion may be panned and scrolled through the entire image with the scroll bars, or by moving the mouse over the image with right button held.

Alternately, to use ''spot'' magnification in XCAP-Plus, XCAP-Std, or XCAP-Ltd, from the PIXCI® Image Viewer, click:

    Examine
    Pixel Magnifier

The magnification factor can be adjusted with:

    Magnification

The ''spot'' size and shape can be adjusted with:

    Magnifier Size
    Square
vs  Circle

The ''spot'' position can be moved interactively by clicking:

    Coord<=>Cursor

A cursor now appears over the image window; clicking the mouse on the image window moves the cursor to that position, and spot magnifier to be centered on that position.

To re-orient the displayed image on to its side or top, or to mirror the displayed image, from the PIXCI® Image Viewer, click:

    View
    Flip & Mirror

and select an up, down, left or right orientation and select one of two mirror options.

4.5.3. Numeric Pixel Values

To examine numeric values of pixels as a table, from the PIXCI® Image Viewer, click:

    Examine
    Pixel Peek

A table of pixel values for a portion of the image appears, showing pixel values in the neighborhood of the displayed X and Y coordinates. The portion of the image numerically displayed can be moved by using the scroll bars, or by entering new X and Y coordinates.

The portion of the image which is numerically displayed can also be moved interactively by clicking:

    Coord<=>Cursor

A cursor now appears over the image window (the Pixel Peek window may have to be moved to the side so that both the pixel peek window and the image viewer window can be seen); clicking the mouse on the image viewer window moves the cursor to that position, and repositions the numerically displayed portion of the image to be centered at that position.

To examine pixel values as a two-dimensional graph, click:

    Examine
    Pixel Plot

and

    Controls
    Where
and Plot Row
or  Plot Column

A graph of pixel values for a line (column) of the image appears, showing pixel values along the line (column) at the displayed Y (X) coordinate. The selected line (column) of the image can be moved interactively by clicking:

    Coord<=>Cursor

A cursor now appears over the image window; clicking the mouse on the image window moves the cursor to that position, and repositions the displayed line (column) to that Y (X) coordinate.

4.6. PIXCI® A310 Video Adjustments

4.6.1. Video Resolution

Reducing the video resolution (the number of pixels captured per line and column) allows capturing more video frames in a given size of frame buffer memory.

From the PIXCI® Image Viewer, click:

    Capture
    Adjustments
    Res(olution)

Click:

    Set Video Window

and draw the new desired area to be captured by left clicking and dragging over the displayed image. Click:

OK

to accept the new capture resolution. Note: Changing the capture resolution will destroy any images previously captured in the frame buffers! The

    Capt(ure)
    Frame Buffers

shows the number of frame buffers available with the current selections.

For interlaced video formats, the resolution can also be switched from interlaced or frame mode (e.g. 480 lines images at 30 Hz for RS-170), to non-interlaced or field mode (e.g. 240 line images at 60 Hz for RS-170). Setting

    Field/Frame Mode: Frame at Frame

captures in frame mode, setting

    Field/Frame Mode: Field at Field

captures in field mode.

4.6.2. Saving the Video Configuration and Adjustments

The selections under the Main Window:

    PIXCI® Video Setup

and under the PIXCI® Image Viewer:

    Adjustments

are automatically saved when the PIXCI® frame grabber is closed, or XCAP is exited. When the PIXCI® frame grabber is next opened, clicking (from the XCAP Main Window):

    PIXCI®
    PIXCI® Open/Close
    Camera & Format

Choose:

    Open w. last used Video Setup

to use the previous video setup, or choose:

    Open w. default Video Setup

to start anew with the default video format, resolution, and video input.

4.7. Saving Images

To save a captured image, from the PIXCI® Image Viewer, click:

    File
    Save Image

Choose a file format, such as:

    TIFF
    BigTIFF
    BMP
    FITS
    JPEG/JFIF
    Portable Map
    X/Y Binary
    X/Y ASCII

The JPEG/JFIF and Windows BMP formats have near-universal support among graphics and imaging applications, with support for 8 bit monochrome and 24 bit RGB color; JPEG/JFIF provides ''lossy'' compression, with adjustment for image quality versus file size. The TIFF format has near-universal support among imaging applications supporting a wide variety of pixel formats and bit depth; TIFF is suggested for saving and reloading an image into XCAP, and suggested for exporting images to other applications. The BigTIFF format is variation of TIFF allowing file sizes larger than 4 Gbyte; however it is not commonly supported. Both TIFF and BigTIFF offer options for lossless compression. The FITS format is commonly used within the astronomy community.

The X/Y Binary and X/Y ASCII export raw pixels, left to right, top to bottom, with no excess information such as dimensions, bit depth, date, format, etc; these are useful for exporting images to a spreadsheet (X/Y ASCII), or to your own program in which the image's dimensions are assumed and can simply read a 2-D array of values. The Portable Map also exports raw binary pixels, left to right, top to bottom, but with minimal information, such as dimensions, at the start of the file.

After selecting a file format, enter a file name:

    File Name:  xx.tif

and click

OK

to save the image. Or, use the:

    Browse

button to access the standard Windows or Linux File Dialog, click

    Accept

to accept the filename selected by browsing, and click

OK

to save the image.

4.8. Capturing an Image Sequence

To capture an image sequence into the frame buffers:

    Capture
    Sequence Capture
    Video to Frame Buffers

select:

    Start/End All Buffers

to capture into all of the frame buffer memory,

    Capture Video Fastest

to capture each video frame (rather than intentionally skipping frames),

    Linear Sequence

to capture into each frame buffer once, then stop (rather than capturing continuously, reusing frame buffers until explicitly stopped),

    Event Free

to capture without waiting for additional events, and and click:

    Record

The VideotoFrameBuffers captures into frame buffer memory; to request more frame buffer memory and a thereby a longer sequence use the

    Driver Assistant

A variety of Sequence Capture features are available, providing tradeoffs between capture rate vs. convenience vs. total number of images captured. The Video to Frame Buffers captures sequences directly into pre-configured frame buffer memory, and can support the maximum frame rate. The Video to Virtual Memory captures and copies sequences into host computer (virtual) memory which is conveniently allocated as-needed, but may not support maximum frame rate capture for all cameras on all computers. The Video to Disk File captures and copies sequences into a disk file in an efficient, internal format (after capture the sequence can be saved in a standard format), but frame rate is limited by the bandwidth of the computer and disk subsystem.

The Video to Image Files captures and copies sequences directly into standard format image files, but with more overhead than the Video to Disk File feature. Optionally, each captured image can also be saved offsite directly to an FTP URL. Optionally, the HTTP server (i.e. web server) feature of XCAP allows access to the sequence of images - as they are being captured - via an internet web browser.

4.9. Saving Image Sequences

To save a captured image sequence, from the PIXCI® Image Viewer, click:

    File
    Save Image Sequence

Choose a file format, such as:

    One TIFF w. Sequence
    One AVI/DIB w. Sequence
    One AVI/MJPG w. Sequence
    One BigTIFF w. Sequence
    One FITS w. Sequence
    One Portable Map w. Sequence
    One X/Y Binary w. Sequence
    One X/Y ASCII w. Sequence
    Sequence of BMP's
    Sequence of BigTIFF's
    Sequence of FITS's
    Sequence of JPEG/JFIF's
    Sequence of TIFF's
    Sequence of Portable Map's
    Sequence of X/Y Binary's
    Sequence of X/Y ASCII's

The One TIFF, One BigTIFF, One FITS, One Portable Map One X/Y Binary, and One X/Y ASCII w. Sequence save the entire image sequence into a single file, with similar utility as described above for the corresponding file format.

The One AVI/DIB and One AVI/MJPG w. Sequence save the entire image sequence as one Windows AVI file using a ''DIB'' or a ''MJPG'' codec, respectively; essentially multiple BMP or multiple JPEG/JFIF formated images, respectively, with the same supported bit depth and compression options described above.

The other options save each image as an individual file.

Only the One TIFF q. Sequence format and the Sequence of ... formats are available in XCAP-Lite.

After selecting any of the ''One .. w. Sequence'', file formats, enter a file name:

    File Name:  xx.tif

and click:

OK

to save the image(s). Or, use the:

    Browse

button to access the standard Windows or Linux File Dialog, click:

    Accept

to accept the filename selected by browsing, and click:

OK

to save the image(s).

If using any of the ''Sequence of ..'' file formats, enter a file name pattern:

    File Name:  xx???.tif

where the ''?'' characters will be replaced by a numerical index, (enter sufficient ''?'' characters as per sequence length; three ''?'''s are sufficient for 1000 images) and click:

OK

to save the image(s).

5. XCAP Software Guide

XCAP is a family of sophisticated, interactive, imaging programs specifically designed to support the PIXCI® series of frame grabbers, but also able to process and analyze images from other imaging sources. Several versions of XCAP are available: XCAP-Plus, XCAP-Std, XCAP-Ltd, XCAP-Lite, and XCAP-Viewer. All versions share the same user interface and menu structure, but selected features in XCAP-Std, XCAP-Ltd, XCAP-Lite, and XCAP-Viewer are not operational. XCAP is distributed on CD/DVD, or downloadable from the EPIX, Inc. website. After installation, a 12 character activation or ID code^[6] is entered to configure XCAP as either XCAP-Plus, XCAP-Std, XCAP-Ltd,^[7] or XCAP-Lite; or, lacking a valid activation or ID code, configured as XCAP-Viewer.

XCAP-Std is an interactive, imaging program designed for scientific, industrial, and machine vision applications. XCAP-Std supports the PIXCI® frame grabber, providing video format and resolution configuration; continuous (live), video rate sequence, and triggered capture; and single or sequence, zoomed or resized, display. The image frame buffers of PIXCI® frame grabbers can be loaded, examined, processed, analyzed, measured, printed, annotated, and saved.

XCAP-Std also allows loading, analyzing, modifying, and saving a pre-existing image or image sequence with size, pixel depth, and color space independent of the PIXCI® frame grabber's configuration; XCAP-Std can be used with pre-existing images even when the PIXCI® frame grabber is not present. XCAP-Std can also acquire images from TWAIN compliant devices.

XCAP-Plus provides extra, advanced, features in addition to all of the capabilities of the XCAP-Std, such as support for specialized, optional, hardware.

XCAP-Ltd is a simplified version of XCAP-Std. XCAP-Ltd provides the same image acquisition and PIXCI® frame grabber control capabilities, the same image display features, and the same image loading, examining, printing, and saving of single image or sequences of images. Only minimal image processing, measurement, analysis, and scripting features are functional. XCAP-Ltd can be used with pre-existing images even when the PIXCI® frame grabber is not present.

XCAP-Lite is a much simplified version of XCAP-Std. XCAP-Lite provides similar image acquisition and PIXCI® frame grabber control capabilities, video format and resolution configuration; continuous (live), video rate sequence, and triggered capture; and single or sequence, zoomed or resized, display. XCAP-Lite also provides some of the image loading, examining, printing, and saving features, but minimal processing, measurement, analysis, and scripting features are functional. XCAP-Lite allows loading and saving single images, as well as image sequences in TIFF format.

XCAP-Viewer allows browsing through the dozens of processing, measurement, analysis, and graphics features provided in XCAP-Plus, XCAP-Std, XCAP-Ltd, or XCAP-Lite. XCAP-Viewer can load and display pre-existing single images. The PIXCI® frame grabber can't be operated with the XCAP-Viewer version.

As XCAP-Plus, XCAP-Std, XCAP-Ltd, XCAP-Lite, and XCAP-Viewer share many common features, this manual typically refers to all versions as XCAP, except where explicitly differentiated.

The XCAP features are organized into two major types of windows, the Main Window and one or more Image Viewer Windows.

For each image, or sequence of images, an Image Viewer Window shows that image, or a selected image of that sequence, and via its menu bar allows viewing, examining, processing, analyzing, or drawing upon that image (sequence). The Image Viewer Window associated with the PIXCI® frame grabber's frame buffers also provides features for capturing new images. There can be multiple Image Viewer Windows for the same image (sequence), allowing, for example, viewing the image both magnified (i.e. zoom) and unmagnified, or simultaneous viewing of different images of a sequence.

The Main Window allows creating new image (sequences), and thus new Image Viewer Windows, either by loading a new image from file, explicit specification of the new image's dimensions, or by opening the PIXCI® frame grabber for use. Video setup for the PIXCI® frame grabber, such as modifying the video resolution or color space, are also in the Main Window; these features may close and re-create the PIXCI® frame grabber's Image Viewer Window. The Main Window also provides features not directly associated with an image (sequence), such as scripts, RS-232 device control, and features to customize XCAP.

5.1. The Main Window

The XCAP main window provides a menu bar with File, Images, Scripts, Utility, PIXCI®, and Help features.

5.1.1. Main Window - File

The main window's File allows loading of pre-existing images into new image buffers, displaying attributes about pre-existing images, and acquiring images from TWAIN compliant devices.

The Load New Image and Load New Image Sequence creates a new image buffer (sequence) with dimensions, pixel depth, and color space matching a specified AVI (Audio Video Interleaved), BigTIFF (Tagged Image File Format extended for large file sizes), BMP (Bitmap), FITS (Flexible Image Transport System), JPEG (Joint Photographic Exports Group), PBM/PGM/PBM (Portable Bit/Gray/Pixel Map), TIFF (Tagged Image File Format), VIF (Video Frame Files - Video to Disk) or multimedia format file(s), and loads the image(s) from the file(s). This feature, and the image buffer (sequence) created, is unrelated to the PIXCI® frame grabber's frame buffers. After creation and loading, the new image (sequence) is displayed, processed, and analyzed in a new instance of The Image Viewer Window, described below. Using wild cards, the Load New Image can also load multiple image files - each to their own new image buffer.

The Load New Image can also load images directly from an Internet URL.

The Image File Info displays information about a specified AVI, BigTIFF, BMP, FITS, JPEG, PBM/PGM/PPM, TIFF, or VIF format file without loading the image. The information displayed includes the image's dimensions, pixel depth, color space, palette option, and other file format specific information.

The TWAIN Select Source and TWAIN New Acquire allow using XCAP as a TWAIN Application, acquiring images from TWAIN compliant imaging devices (TWAIN Sources). The TWAIN Select Source allows selecting which TWAIN Source is to be used, and the TWAIN New Acquire allows acquiring one image from the TWAIN Source.

The Window List displays a list of active windows belonging to XCAP; selecting a window causes that window to appear, if previously hidden, and/or to appear over other windows (subject to the priority of selected windows to always appear ''on top'').

5.1.2. Main Window - Images

The main window's Images allows creating new image buffers and activating any existing image windows that may not be on-screen.

The New Image creates a new image buffer, or sequence of image buffers, with specified dimensions, pixel depth, color space, and palette. This feature, and the image buffer created, is unrelated to the PIXCI® frame grabber's frame buffers. After creation, the new image is displayed in a new instance of The Image Viewer Window, as described below.

Underneath New Image are listed all existing image windows, whether for PIXCI® frame grabber frame buffers, or for independent image buffers. (The image window for PIXCI® frame grabber frame buffers appears only after the PIXCI® frame grabber has been opened for use, see below). An image window which has been closed and is thereby off-screen can be reactivated by clicking the image window's name.

5.1.3. Main Window - Scripts

The main window's Scripts provides features for recording and playing scripts. A script recording contains most of the user's interactions with the windows of XCAP; playing the script duplicates the original actions.

Some user actions are not recorded. Using the mouse to drag the cursor or other graphic across an image is not recorded as these actions are highly dependent upon image content (such as the typical scenario of dragging the cursor until it is positioned next to an artifact in a captured image), would likely be inappropriate to other captured images, and recording each mouse ''step'' would consume a significant amount of disk space. Instead, after positioning the cursor interactively the user can record the final position by clicking the appropriate numeric cursor coordinates. Similarly, the activation of a feature with shortcut keys or shortcut icons is not recorded; instead features can be activated via the non-shortcut alternative, which is recorded.

A recorded script is in a human readable form and can be altered with any common editor capable of handling ASCII text, allowing scripts to be modified or combined. A selected script may be executed automatically after XCAP starts, this feature is set in Utility, Program Setup, Startup Script.

The Load Tool Bar provides one or more user-defined tool bars of shortcuts, each shortcut represented by an icon which, when clicked, executes a user-specified script. Each shortcut may also specify an optional keyboard key which, when pressed, also executes the user-specified script.

The Script Remote Control allows using XCAP as a hidden, off-screen, ''black box''; any end-user application that can manipulate text files, can also remotely control XCAP.

5.1.4. Main Window - Utility

The main window's Utility provides an assortment of features that are of secondary importance; features that allow fine tuning of XCAP, or features needed in relatively few circumstances.

The Black Board allows customizing XCAP, creating non-procedural programs, and collecting data. The black board allows inter-connecting the numeric and text field of other windows; computed results, such as center-of-mass, may be written onto the black board - parameters for other features, such as the coordinates of a displayed grid, may be extracted from the black board - combining these automatically repositions the grid as the center of mass is recomputed! Other features allow computed values (similar to a spreadsheet), ''push''ing buttons, timed updates, creating a report to file or an RS-232 port, collecting data, and graphing the black board's contents.

A Message Log window lists warnings and errors that arise from performing various operations. By default, the message log window appears automatically when a message is added, and disappears a few seconds later. Auto appearance, auto hide, and audible clicks can be disabled (from the message log window's menu bar). The menu-bar's Message Log allows explicit activation of the message log window.

The Program Setup shows information about the installed XCAP components, such as their revision level, and sets various configuration options. For versions of XCAP that require an authorization key, it also shows the ID of the key required by the instant copy of XCAP.

The Program Setup allows specifying the name of a script to be executed when XCAP starts, whether warning pop-up windows (if any) are to be shown, whether previously saved settings are to be loaded, and other similar initial or terminal conditions.

The Program Setup also enables user-defined translation of XCAP labels and messages for use in non-English speaking countries.

The Windows Info displays information about the current Windows environment, such as memory usage and the graphics display system's features, as reported by Windows.

The Linux Info displays information about the current Linux environment, such as memory usage and the graphics display system's features, as reported by Linux. The Java Info displays information about the status of Java, under which XCAP runs. Both of these features are primarily of use in resolving questions submitted to EPIX, Inc. Technical Support.

The Window Style allows setting some characteristics of XCAP windows, such as color or character size and font. Some characteristics of window style are instead controlled by the Windows Control Panel.

The Audio Clip (only under Windows) allows recording and playing short audio ''clips''.

The RS-232 Terminal allows ''raw'' communication with a camera or other device connected via the computer's RS-232 port. The RS-232 Terminal is designed specifically for device control, including options to communicate with byte values, rather than as a common ''terminal emulator''. XCAP may also provide more convenient, camera-specific ''smart'' controls, provided after a camera-specific frame grabber is opened, via the Capture - Adjustments.

The I/O Port Peek & Poke allows controlling arbitrary devices accessible via I/O port peeks and pokes. This feature must be used with caution; peeking or poking arbitrary ports will cause computer malfunction! This feature is only available under Windows 95, 98, and ME.

The Screen Capture allows capturing the current graphics display screen, saving the graphics to a file, or printing the graphics. The Screen Capture also allows capturing numeric and textual parameters into a text file, suitable for loading into a spreadsheet or other programs.

The Volpi intralux dc-1100 and Illumination Technologies 3900 provide support for controlling these light sources through their RS-232 ports.

The Birger EF232 provides support for controlling the Birger EF232 RS-232 Lens Mount.

The Fujinon CCTV Lens provides support for controlling Fujinon CCTV Lenses that follow the Fujinon C10 Protocol.

The Directed Perception Pan-Tilt Unit provides support for controlling the Directed Perception Pan-Tilt Units.

The Sagebrush Pan-Tilt Gimbal provides support for controlling the Sagebrush Pan-Tilt Gimbals that follow the Sagebrush 2.0 Protocol.

The EPIX® SILICON VIDEO® 20C-CL, EPIX® SILICON VIDEO® 20M-CL, EPIX® SILICON VIDEO® 1514CL, and EPIX® SILICON VIDEO® 1820CL provide support for configuring the EPIX® SILICON VIDEO® 10C-CL, SILICON VIDEO® 10M-CL, SILICON VIDEO® 20C-CL, SILICON VIDEO® 20M-CL, SILICON VIDEO® 1514CL, and SILICON VIDEO® 1820CL cameras via a virtual ''COM'' port (under Windows), a virtual ''ttyS'' device (under Linux), or a Camera Link Serial API DLL (i.e. a clserXXX.DLL, under Windows). These are provided for configuring the camera when using a frame grabber other than an PIXCI® frame grabber, leaving configuration of the frame grabber to its software. When using a PIXCI® frame grabber, the alternative PIXCI® - Open/Close is recommended as it provides integrated controls for both camera and frame grabber.

5.1.5. Main Window - PIXCI®

The main window's PIXCI® allows initiating access to the PIXCI® frame grabber and provides configuration options. Actual operation of the PIXCI® frame grabber is performed through the PIXCI® image viewer window's menu-bar.

The PIXCI® Open/Close allows opening access to, or closing access to, the PIXCI® frame grabber. Once open, the model, and submodel or preset camera & format selection, as appropriate, of the PIXCI® frame grabber is available via the Board Info button. After opening, the contents of the PIXCI® frame grabber's image frame buffer(s) are displayed in a new instance of The Image Viewer Window, along with a tool bar of PIXCI® Image Viewer - Capture - Shortcuts and a status bar of Image Viewer - View - Status Bar are shown as described below.

The PIXCI® Video Setup allows configuring the video format, video resolution and other, model specific, video characteristics. For the PIXCI® SV2, SV3, SV4, SV5, SV5A, SV5B, and SV5L models, the PIXCI® Video Setup allows selecting NTSC, RS-170, NTSC/S-VIDEO, CCIR, PAL, or PAL/S-Video formats, allows selecting the video window size, capture resolution, and other video acquisition characteristics.

For the PIXCI® SV7 models, the PIXCI® Video Setup allows selecting NTSC, RS-170, CCIR, or PAL formats , allows selecting the video window size, capture resolution, and other video acquisition characteristics.

For the PIXCI® SV8 models, the PIXCI® Video Setup allows selecting NTSC, RS-170, NTSC/S-VIDEO, CCIR, PAL, or PAL/S-Video formats, allows selecting the video window size, capture resolution, and other video acquisition characteristics.

For the PIXCI® A310 model, the PIXCI® Video Setup allows selecting Video 720x480i 60Hz (RS-170), Video 720x480i 60Hz RGB, Video 720x576i 50Hz (CCIR), Video 720x576i 50Hz RGB, Video 1920x1080i 60Hz, Video 1920x1080i 60Hz RGB, Video 1920x1080i 50Hz, Video 1920x1080i 50Hz RGB, Video 1920x1080p 60Hz, Video 1920x1080p 60Hz RGB, Video 1920x1080p 50Hz, Video 1920x1080p 50Hz RGB, Video 1280x720p 50Hz, Video 1280x720p 50Hz RGB, Video 1280x720p 60Hz, Video 1280x720p 60Hz RGB, RS330 720x480i 60Hz, RS343 875i 60Hz, RS343 875i 60Hz RGB, SVGA 800x600 60Hz, SVGA 800x600 60Hz RGB, SXGA 1280x1024 60Hz, SXGA 1280x1024 60Hz RGB, VGA 640x480 60Hz, VGA 640x480 60Hz RGB, XGA 1024x768 60Hz or XGA 1024x768 60Hz RGB formats, allows modifying the PLL, A/D, and sync processor parameters to accommodate other video formats, allows selecting the capture resolution, and selecting other video acquisition characteristics. For the PIXCI® A110 model, the PIXCI® Video Setup is similar, but does not allow selecting RGB formats.

For the PIXCI® CL1, CL3SD, D, D24, D32, D2X, D3X, and D3XE models, fewer options are provided, as these frame grabbers are each customized to specifically support one camera, or a related group if cameras. For the PIXCI® CL2, E1, E1DB, E4, E4DB, E4G2-2F, E4G2-4B, E4G2-F2B, E4TX2-2F, E4TX2-4B, E4TX2-F2B, E8, E8DB, e104x4-2f, e104x4-4b, e104x4-f2b, EB1, EB1G2, EB1-PoCL, EB1G2-PoCL, EB1mini, miniH2B, miniH2F, miniH2x4F, mf2280, EC1, ECB1, ECB1-34, ECB2, EL1, and EL1DB models, which provide universal support for Camera Link cameras, fewer options are provided. For the PIXCI® E8CAM, ELS2, SI, SI1, SI2, and SI4 models, which support SILICON VIDEO® cameras, fewer options are provided. For all of these, a different camera can be selected, if available, via PIXCI® Open/Close, Camera & Format.

The current video setup is automatically saved when access to the PIXCI® frame grabber is closed, and reloaded when the PIXCI® frame grabber is later opened. The PIXCI® Export Video Setup and PIXCI® Import Video Setup may be used to explicitly save or reload the current video setup, such as to choose amongst several favorite setups, or to export the current video setup to the XCLIB library.

The PIXCI® Status shows the PIXCI® frame grabber's current status, such as the state of the general purpose (formerly referred to as an external TTL) trigger input(s) and output(s), the number of elapsed video fields, the board's model, submodel or preset camera & format selection, as appropriate, and configured image memory size.

The PIXCI® Serial Terminal allows ''raw'' communication with a camera connected to the serial port on selected models of the PIXCI® frame grabber. For many cameras, XCAP includes more convenient, camera-specific ''smart'' controls, provided after a camera-specific frame grabber is opened, via the Capture - Adjustments.

The PIXCI® Connections provides, as appropriate for the specific model of PIXCI® frame grabber, a map of the board's connections, connectors, option jumpers, and adjustments.

The PIXCI® Camera Info provides a list of cameras and video formats supported by XCAP and various PIXCI® frame grabbers. The PIXCI® Camera Info also allows viewing a non-operational Capture - Adjustments window (i.e. the ''Control Panel'', which provides integrated control of both frame grabber and any supported camera).

The PIXCI® TWAIN Sourcery (only under Windows) allows using XCAP, in conjunction with the ''XCAP Sourcery'' TWAIN driver, as a component of a ''smart'' TWAIN Source, allowing other applications to capture images from the PIXCI® frame grabber, while XCAP provides frame grabber controls, camera controls, and, optionally, image preprocessing.^[8] The PIXCI® TWAIN Sourcery should not be confused with TWAIN New Acquire; the former allows XCAP to provide image data to other, TWAIN compliant applications; the latter allows XCAP to accept image data from other TWAIN compliant sources. The TWAIN New Acquire should never be used to attempt to acquire image data from the PIXCI® TWAIN Sourcery!

The PIXCI® Image-Pro Sourcery (only under Windows) allows using XCAP, in conjunction with the ''XCAP Sourcery'' Image-Pro driver, as a component of a ''smart'' video source, allowing Image-Pro to capture images from the PIXCI® frame grabber, while XCAP provides frame grabber, camera controls, and, optionally, image preprocessing.^[8]

5.2. The Image Viewer Window

Each image buffer (sequence), or frame buffer (sequence), is displayed in an image viewer window, which is the focus of activity for examining, processing, or analyzing that image buffer (sequence). The image viewer window provides a menu bar with File, View, Examine, Modify, Measure, Draw, AOI, and Help features. The image viewer window associated with the PIXCI® frame grabber's frame buffer(s) also provides a Capture feature.

5.2.1. Image Viewer - File

The image viewer window's File allows saving, loading, or printing the image, shows information about the image's dimensions, pixel depth and color space, and allows closing the image viewer window.

The Load Image and Save Image allow saving or loading the image in a variety of file formats. The Load Image, unlike the Load New Image described above, loads an image file into the current image buffer, resizing and/or color converting to fit the image buffer's existing dimensions, pixel depth, and color space. The Load Image can also load images directly from an Internet URL.

For image viewer windows associated with an image buffer sequence, the Save Image Sequence and Load Image Sequence allow saving or loading multiple images of the sequence as a numbered sequence of image files, or as a single AVI, BigTIFF, FITS, PBM/PGM/PPM, or TIFF format image file with multiple images. Save Image can also save images directly to an FTP URL.

The E-Mail Image allows directly e-mailing the image, in a variety of file formats, from within XCAP.

The Print Image allows printing the image; either via the operating system's built-in image printing feature(s) which typically supports a wide variety of printers, or via EPIX® imaging drivers which support only the most popular printers, but providing precise control of print options.

The Image Attributes shows the image's (or image sequence's) dimensions, pixel depth, and color space.

The Duplicate Image and Duplicate Image Sequence allows creating a new image buffer and copying the current image, or creating a new sequence of image buffers and copying the current image sequence, respectively, in one step. It optionally allows copying the image's (or image sequence's) current appearance, as modified by the palette and graphics, instead of the underlying image (or image sequence).

The BlackBoard Image allows copying the image's pixel values into the Black Board.

The Close Viewer closes the window, but does not destroy the image (sequence). The Close & Dispose of Image closes the window and destroys the image (sequence). The image viewer window associated with the PIXCI® frame grabber's frame buffer(s) does not provide a Close & Dispose of Image; an image viewer window is available whenever the PIXCI® frame grabber is open for use.

5.2.2. Image Viewer - View

The image viewer window's View provides options governing the appearance of the displayed image.

The Shortcuts allows activating or deactivating a tool bar of icons providing shortcuts for accessing often used features, and is described under Image Viewer - View - Shortcuts.

The Status Bar allows activating or deactivating a small status bar with current information, and is described under Image Viewer - View - Status Bar.

The Menu Bar allows activating or deactivating the menu bar; when deactivated, clicking the mouse right-click button allows restoring the menu bar.

For image viewer windows associated with the PIXCI® frame grabber's image frame buffer(s), the Adjustments allows setting common adjustments, as suitable for the model of the PIXCI® frame grabber in use, and is described under PIXCI® Image Viewer - Capture.

The Full Screen allows displaying the image in the full graphics display screen without the menu bar, centered with black border (if needed), and with little or no window ''frame'' around the image. The previous display mode can be restored via a mouse right-click.

The Always-On-Top allows forcing the image viewer window, and its subwindows, to always be ''above'' other windows; subject to the other windows' also requesting Always-On-Top, and the whims of the host operating system. This option is typically useful only when XCAP is being used in combination with other applications, such as in conjunction with the PIXCI® TWAIN Sourcery or PIXCI® Image-Pro Sourcery feature. The Always-On-Top feature is only supported under Windows.

The Refresh forces the displayed image to be redrawn once; normally manual refresh is not needed, but occasionally, when the image was (partly) covered and uncovered by other window(s), the displayed image might ''forget'' to be updated.

For images composed of index pixels and palette, the Image's Palette allows manipulating the image's attached palette; for images of other types, the Image's Palette is not selectable. For all images, the Viewer's Palette allows manipulating a palette which is not attached to the image. Either can be used for contrast enhancement, adjustment of black level and gain, or, for monochrome images, false coloring. Either, or neither, of the palettes can be selected for use under Display.

For image sequences, the Sequence Play allows ''playing'' the sequence, image by image, at a selected rate.

The Sequence Thumbnails window shows each image of a sequence as a small ''thumbnail'' image, allowing compact presentation and review of the entire image sequence. Clicking on a thumbnail can select that image for display by the image viewer window.

The Cursor allows activating a cursor over the image, which may be positioned via coordinates, or by left clicking the mouse on an image feature.

The Display allows selecting how the image is displayed: (a) No resizing so there is a one to one relationship between an image pixel and a displayed graphics display pixel and is the quickest, although the entire image may not fit within the window and must therefore be panned and scrolled, (b) Resize by nearest neighbor which is relatively quick, or (c) Resize by bilinear interpolation which may produce better results for continuous tone images, but is slower. For the resize modes, the aspect ratio can also be modified. The Display allows selecting which palette, if any, is to be used during display and during file loads and saves. An option to display only even lines, or only odd image lines, allows avoiding interlace artifacts during display. For the image viewer window associated with the PIXCI® frame grabber's frame buffer(s), the Display provides additional features, identical to the Live Options described below.

The Zoom, Pan, Scroll allows magnifying the displayed image, panning and scrolling to view different portions of the image under magnification. For image sequences, a specific image of the sequence can be selected for display. In addition to panning and scrolling via explicit coordinates and via scrollbars, holding the right mouse button and moving the mouse over the image also implements panning and scrolling. Optionally, the left or right mouse button can be used to increase magnification (i.e. zoom-in) or decrease magnification (i.e. zoom-out).

The Flip & Mirror allows flipping and mirroring the displayed image so that the top is displayed to the top, left, right, or bottom.

Each image buffer (sequence) may have several simultaneously active viewers, allowing, for example, viewing the same image buffer both magnified and unmagnified. The Launch 2nd Viewer creates a second image viewer window into the same image buffer (sequence), with the same features as the original image viewer window.

5.2.3. Image Viewer - Examine

The image viewer window's Examine provides options to examine the image.

The Pixel Peek allows numeric display of the pixel values in the vicinity of the image cursor — within a single image, or across a sequence of images, or of a multi-image stack. The feature also graphically displays each pixel's value or trends.

The Pixel Peek & Poke allows numeric display and modification of individual pixel values. The Pixel Peek & Poke also allows precise, single pixel, image editing.

The Pixel Plot displays a two-dimensional graph of pixels values along a selected image line or column, of all image lines or columns, of an image pixel as it varies across an image sequence, of rows or columns as they vary across an image sequence, or of a multi-image stack. The recent trends of pixel values can also be shown, as an fading ''echo,'' to help visually evaluate the fluctuations of live video or the effects of camera adjustments. Features attached to the graph show specific pixel values and descriptive statistics such as lowest value, highest value, mean value, and standard deviation.

The Pixel Plot 3D displays the numeric values of pixels as as a three-dimensional graph — from a single image or from a multi-image ''stack'' — with the image X and Y coordinates composing two dimensions, and the pixel values composing the third dimension.

The Pixel Magnifier allows enlarging an area of the displayed image, with an effect similar to using a magnifying lens. Optionally, contrast and other enhancements can be applied to the magnified area.

The SMPTE VITC allows searching the image for valid SMPTE Vertical Interval Time Codes and displaying the decoded codes.

5.2.4. Image Viewer - Modify

The image viewer window's Modify provides image processing operations which modify the image, modify each image (independently) in a sequence (typically named ''Sequence ...'') or modify one or more images in a sequence by combining data from across multiple images (typically named ''... Sequence ).''

The FFT provides Fast Fourier Transforms and Discrete Fourier Transforms. The Sequence FFT does the same on each image of a sequence. The Src+Dst FFT does the same with distinct source and destination images.

The HSB Tweak provides hue, saturation, and brightness adjustments within the HSB color space. While Arithmetic and other operations can optionally use the HSB color space to, for example, multiply all saturation values by a constant, the HSB Tweak allows adjusting selected portions of the HSB space, such as adjusting the brightness of red pixels with high saturation. The Sequence HSB Tweak does the same on each image of a sequence. The Src+Dst HSB Tweak does the same with distinct source and destination images.

The Interlace & Flicker provides line and pixel shuffling operations. The Sequence Interlace & Flicker does the same on each image of a sequence. The Src+Dst Interlace & Flicker does the same with distinct source and destination images.

The Tile Sequence allows forming a grid of reduced images from an image sequence.

For image copy and other image processing operations utilizing a distinct source and destination, the image viewer window from which the operation is selected is always the modified destination; an image (or sequence) associated with a different image viewer window can be selected as the unmodified source.

5.2.5. Image Viewer - Measure

The image viewer window's Measure provides features for image measurement and analysis, including user-defined coordinate systems and mapping intensities into user-defined units.

The Intensity Calibration allows creating a mapping (correspondence) from monochrome image pixel values into user-defined units, for example from grey level into brightness, or grey level into density of material.

The Spatial Calibration allows creating a mapping (correspondence) from pixel X,Y coordinates into a user-defined H,V coordinate system. The H,V coordinates may be translated, scaled, and/or rotated with respect to X,Y coordinates.

The Histogram computes and displays a graph of an image's histogram.

The Histogram Pair computes and displays a graph of the histogram of difference of a pair of images.

The Mass & Moments computes and displays various moments of an image.

The Ruler overlays a ruler on the image, with user-defined length, width, and tick marks, all based on the H,V coordinate system. Multiple rulers can be overlaid on each image.

The Protractor overlays a protractor on the image, with user-defined radius, arc, and tick marks, all based on the H,V coordinate system. Multiple protractors can be overlaid on each image.

The Cartesian Reticle overlays a Cartesian coordinate reticle on the image, based on the H,V coordinate system. Multiple Cartesian reticles can be overlaid on each image.

The Polar Reticle overlays a polar coordinate reticle on the image, based on the H,V coordinate system. Multiple polar reticles can be overlaid on each image.

The Distance & Angle Crosshairs provides spatial calibration and measurement of absolute position, relative position, length and angles. While these capabilities are also available elsewhere in Image Viewer - Measure and Image Viewer - Draw, the Distance & Angle Crosshairs collects chosen features to provide a single window with the equivalent of a so-called ''Video Crosshair Overlay & Measurement'' system.

The Shape Analysis provides descriptive statistics about the shape of elliptical, rectangular, or polygonal regions.

The Blob Analysis identifies image blobs, based upon thresholding the image into foreground and background, and provides descriptive statistics about the blobs found.

The Particle Tracking provides identification and tracking of particles (blobs) over a sequence of images. Individual particles are detected based upon a thresholded (bi-level) image. In one method, multiple image occurrences of a common particle are identified across a sequence of images by position extrapolation and verification. In a second method, vectors of particles that are close together are compared and expected to yield consistent magnitude and direction. In a third method, which requires the fewest setup parameters, common particles are grouped by nearest neighbor. For any method, the particle's trajectories are displayed and reported.

The SubPixel Edger overlays a line or curve tool on the image, analyzes the pixel values under the line or curve finding edges or lines to subpixel accuracy, and displays the position of the edges or lines both graphically, on the image, and numerically.

The Ellipse Fitter overlays an elliptical pattern of subpixel edger tools on the image, and computes a best-fit elliptical curve from the edges found.

The Correlation Finder correlates, or matches, a kernel image over a larger image, showing the coordinates of, and displaying a box around, the best match(es).

5.2.6. Image Viewer - Draw

The image viewer window's Draw provides features for drawing graphics and text over the image. One or more of: line, circle with aspect ratio correction, rotated rectangle, rotated ellipse, arc of circle with aspect ratio correction, arc of rotated ellipse, annulus, arc of annulus, rectangular frame, list of points, polygon, polyline (connected line segments not closed into a polygon), Bezier curve, or Bezier region (Bezier curve closed to form region), rotated text, and arrow may be overlaid over the image (non destructive) or written into the image. The individual menu items such as Text, Line, Rectangle, etc. allow quick drawing of graphics or text. The Graphic Manager permits drawing the same graphics or text, but in addition manages a list of graphic or text objects, including loading and saving of the graphic or text objects.

The Image Overlay feature allows overlaying a second image, containing graphics on a ''transparent'' background, over the current image.

The Paint Brush feature allows interactive ''painting'' onto the image with selectable color, patterns, and ''brush'' shapes.

The Paint Fill feature allows filling (flooding) an image region with ''paint'' of selectable color and patterns, using specified pixel values as the boundary terminating the ''filling''.

5.2.7. Image Viewer - AOI

The image viewer window's Aoi allows defining areas of interest (AOI) and regions of interest (ROI) upon which future image processing, measurement, analysis, print, load, and save features will operate. As used in XCAP, an ''AOI'' is a rectangular area with sides parallel to the image axis, while an ''ROI'' is of arbitrary shape, such as an ellipse or rectangle which may be rotated with respect to the image axis, or an arbitrary path or polygon. The image print, load, save, and many other features only allow use of an AOI; selected image processing, measurement, analysis and other features also allow use of an ROI.

The Set AOI defines the default area of interest and color space upon which future image processing, printing, load, and save features will operate.

The Set ROI defines the default region of interest and color space upon which future image measurement, analysis, and other selected features which accept an ROI will operate.

The Set Full Image quickly sets the default area of interest and region of interest to the image's full dimensions, and the default color space to the image buffer's natural color space, without entering the Set AOI or Set ROI window.

The AOI/ROI Manager maintains a list of often used areas of interest (AOI) and regions of interest (ROI).

Within each of the image processing, measurement, analysis, print, load, and save features a different AOI (or ROI, if applicable) can be selected, temporarily overriding the default AOI (or ROI). Within the feature, the new AOI (or ROI) can be specified numerically or interactively drawn, or an AOI (ROI) previously defined within the AOI/ROI Manager can be selected.

5.2.8. Image Viewer - View - Shortcuts

A tool bar of icons provides shortcuts for accessing often used features of The Image Viewer Window. Selected shortcuts can also be activated by key clicks when the tool bar window has the ''input focus'' (i.e. that window's title bar is highlighted). The shortcuts provided are:

Switch to first buffer of sequence (Key HOME).
Switch to next buffer of sequence (Key PAGE UP).
Switch to previous buffer of sequence (Key PAGE DOWN).
Switch to last buffer of sequence (Key END).
Copy image to new image buffer.
Adjust palette.
Activate or deactivate zoom (i.e. magnification).
Peek at numeric pixel values.
Activate or deactivate cursor overlay.
Draw a two-dimensional plot of line or column of pixel values.
Draw a histogram of pixel values.
Select: (a) Resizing of the image to fit The Image Viewer Window with correct aspect ratio, (b) No resizing so that there is a one to one relationship between an image pixel and a graphics display system's pixel thereby avoiding resizing artifacts (although the entire image may not fit within the window and must therefore be panned and scrolled, and the displayed aspect ratio will be incorrect for images whose aspect ratio differs from the graphic display system's aspect ratio), or (c) Resize the image via pixel decimation or replication thereby avoiding resizing artifacts (although the displayed aspect ratio will be incorrect for images whose aspect ratio differs from the graphic display system's aspect ratio).

The first four shortcuts appear only for The Image Viewer Window's which access a sequence of images.

The shortcuts may either be attached and part of The Image Viewer Window, or may be detached into its own window, as set by Display under Image Viewer - View.

5.2.9. Image Viewer - View - Status Bar

A status bar provides information about the image resolution, current cursor coordinates, current buffer of a sequence, and other similar information. The information to be shown can be selected by Display under Image Viewer - View.

5.2.10. PIXCI® Image Viewer - Capture

The image viewer window associated with the PIXCI® frame grabber's image frame buffer(s) has Capture which provides for capturing images from the PIXCI® frame grabber and other features associated with the PIXCI® frame grabber. Any additional image viewer windows created by Launch 2nd Viewer do not provide Capture, but only view, modify, examine, and/or draw the frame buffers.

The Snap captures and displays a single image. The Live continuously captures and displays images; the UnLive terminates the Live mode, displaying the last captured image.

The First Buffer switches to the first buffer of the frame buffer sequence, the Last Buffer switches to the last buffer of the frame buffer sequence, the Next Buffer switches to the next buffer of the frame buffer sequence, and the Previous Buffer switches to the previous buffer of the frame buffer sequence.

The Adjustments allows setting common adjustments, as suitable for the model of the PIXCI® frame grabber in use. For the PIXCI® SV2, SV3, SV4, SV5, SV5A, SV5B, and SV5L models, the Adjustments allows selecting the video input connection (N/A for PIXCI® SV5B) and adjusting the gain, black level, hue, and saturation.

For the PIXCI® SV7 model, the Adjustments allows selecting AGC and adjusting the gain, black level, hue, and saturation.

For the PIXCI® SV8 model, the Adjustments allows selecting AGC and adjusting the gain, black level, hue, saturation, and sharpness.

For the PIXCI® A110 and A310 models, the Adjustments allows adjusting the analog gain and offset, and the digital gain and offset. Less frequently used, and more esoteric, adjustments may be found under PIXCI® Video Setup, described above. For the PIXCI® CL1, CL3SD, D, D24, D32, D2X, D3X, and D3XE models, the Adjustments provide camera specific controls.

For the PIXCI® CL2, E1, E1DB, E4, E4DB, E4G2-2F, E4G2-4B, E4G2-F2B, E4TX2-2F, E4TX2-4B, E4TX2-F2B, E8, E8DB, e104x4-2f, e104x4-4b, e104x4-f2b, EB1, EB1G2, EB1-PoCL, EB1G2-PoCL, EB1mini, miniH2B, miniH2F, miniH2x4F, mf2280, EC1, ECB1, ECB1-34, ECB2, EL1, and EL1DB models, the Adjustments provide camera specific controls. Or, for ''Generic Camera Link'' mode, the Adjustments allow configuring the PIXCI® frame grabber's video resolution, trigger modes, bit depth, color space, etc. so as to be consistent with the camera.

For the PIXCI® E8CAM, ELS2, SI, SI1, SI2, and SI4 models, the Adjustments provide camera specific controls.

The Adjustments also provide duplicate features to Snap, Live, UnLive, select the frame buffer, and set the video window size. A duplicate menu item to access Adjustments is provided under Image Viewer - View.

The Shortcuts activates or deactivates the PIXCI® Image Viewer - Capture - Shortcuts, described below. A duplicate menu item to access Shortcuts is provided under Image Viewer - View.

The GIO Event Capture provides single or sequence image capture, each image triggered in conjunction with the frame grabber's general purpose (formerly referred to as an external TTL) input and output signals.

The Sequence Capture features allow capturing a timed sequence of images. The Sequence Capture features may be started by an event (trigger), run continuously until stopped by an event, or each individual image may be captured in response to an event. Events include mouse clicks, time of day, and the frame grabber's general purpose (formerly referred to as external TTL) inputs; when used with general purpose input events the Sequence Capture differs from GIO Event Capture in that the latter provides more options and higher accuracy and repeatability for the manipulation of the general purpose inputs and outputs in response to video timing. A time stamp feature allows recording the time that each image was captured, and either overlaying the time nondestructively or permanently marking the image with the time.

A variety of Sequence Capture features provide tradeoffs between capture rate vs. convenience vs. total number of images captured.

The Video to Frame Buffers captures sequences directly into pre-configured frame buffer memory, and can support any video rate or bandwidth.

The Video to Virtual Memory captures and copies sequences into convenient dynamically allocated host computer (virtual) memory, but may not support high video rate or bandwidth sequence capture for all cameras on all computers.

The Video to Disk File captures and copies sequences into a disk file in an efficient, internal format; after capture the sequence can be saved in a standard format.

The Video to Image Files captures and copies sequences directly into standard format image files, but may not obtain as high video rate capture as the Video to Disk File feature.

The Waterfall Display displays a chosen line of the frame buffer, in a ''waterfall'' fashion, updating the screen once per field, or as often as the host computer's speed allows. This feature is primarily intended for adjusting line scan type cameras. The waterfall display is intended only for viewing; it can't be analyzed, and can be saved only as a side effect of Screen Capture.

The Video to StreamStor (only under Windows) allows recording and playing video to and from Boulder Instruments StreamStor High-Speed Disk Recorders, allowing recording at video rate with almost all cameras and resolutions. The Video to StreamStor is provided only in the XCAP-Plus version.

The RGB Merge allows interpreting and viewing three monochromatic frame buffers as a single color (e.g. RGB) image, with adjustments for registration and coloring.

The Quad Pixel Merge allows interpreting and viewing four monochromatic frame buffers, each one captured after shifting the image sensor by ½ pixel horizontally and vertically, as a single high resolution image.

The Frame Average allows performing recursive, continuous, averaging of live video frames (or fields) and viewing the live result.

The Live Options combines the View - Display options, above, with additional choices governing Live mode. During Live mode, the PIXCI® frame grabber can: (a) Capture continuously into the specified frame buffer, however the image shown on the graphics display may contain portions from different video frames, (b) Snap, display on the graphics display, and repeat, however the image capture and display rate will be slower, or (c) Alternate capturing into the specified frame buffer and the last frame buffer (dual buffering). On host computers with insufficient PCI bandwidth to simultaneously capture into host computer memory and display from host computer memory to the graphics display, option (b) reduces the required bandwidth by approximately half.

The Lens Control - Birger EF232 allows controlling the aperture and focus of a compatible lens via a Birger EF232 Lens Mount. Both manual aperture and focus control, through the GUI, as well as automatic aperture and focus control, in response to the image intensity and sharpness, are provided.

5.2.11. PIXCI® Image Viewer - Capture - Shortcuts

A tool bar of icons provides shortcuts for accessing often used features of the PIXCI® frame grabber, and is an extension of the Image Viewer - View - Shortcuts described above. Selected shortcuts can also be activated by key clicks when the tool bar window has the ''input focus'' (i.e. that window's title bar is highlighted). The shortcuts provided are:

Switch to first buffer of frame buffer sequence (Key HOME).
Switch to next buffer of frame buffer sequence (Key PAGE UP).
Switch to previous buffer of frame buffer sequence (Key PAGE DOWN).
Switch to last buffer of frame buffer sequence (Key END).
Snap single image (Key S).
Toggle between:
- Live mode - continuously capture and display images (Key L), and
- Unlive mode - cease continuously capturing and displaying (Key U).
Duplicate image.
Adjust palette.
Activate or deactivate zoom (i.e. magnification).
Activate or deactivate cursor overlay.
Select: (a) Resizing of the image to fit The Image Viewer Window with correct aspect ratio, (b) No resizing so that there is a one to one relationship between an image pixel and a graphics display system's pixel thereby avoiding resizing artifacts (although the entire image may not fit within the window and must therefore be panned and scrolled, and the displayed aspect ratio will be incorrect for images whose aspect ratio differs from the graphic display system's aspect ratio), or (c) Resize the image via pixel decimation or replication thereby avoiding resizing artifacts (although the displayed aspect ratio will be incorrect for images whose aspect ratio differs from the graphic display system's aspect ratio).
Peek at numeric pixel values.
Draw a two-dimensional plot of line or column of pixel values.
Draw a histogram of pixel values.
Acquire sequence.
Display sequence.

The shortcuts may either be attached and part of The Image Viewer Window, or may be detached into its own window, as set by Display under Image Viewer - View.

5.3. Other Features

Other useful features of XCAP are associated with many, or all, of its windows.

Most windows of XCAP provide fields for numeric entry. Typically, to the right of the numeric entry field are two up/down or left/right buttons. Left clicking a button allows incrementing or decrementing the numeric value. Left clicking within a button's shaded area yields larger increment or decrement values, depending on the distance from the opposite button.

Right clicking the numeric field, either button, or the area between buttons, yields an options menu. The options menu typically provides the following:

Selecting the base to which integer numbers are displayed, or the format and precision to which non-integer numbers are displayed.
Changing the increment and decrement values to be applied when the buttons are left clicked. Selecting whether the increment or decrement is added or subtracted, whether a percentage up or down, or is the number of ''steps'' unique to that numeric field.
Activating a ScrollPad (a miniature scroll bar which overlays the displayed number) allowing adjustment of the numeric value with mouse clicks and drags.
Selecting units and range for display of angles, such as 0 to 360 degrees, -180 degrees to +180 degrees, 0 to 2pi radians, or -pi to +pi radians.
Selecting units for display of temporal intervals, such as milliseconds, seconds, minutes, or hours.
Selecting units for display of lengths, such as millimeters, centimeters, meters, inches, or feet.
Selecting units for display of frequencies, such as Hertz, kiloHertz, megaHertz, or the corresponding period in seconds, milliseconds, or microseconds.
Selecting units for display of memory sizes, such as bytes, kilobytes, megabytes, gigabytes, or IEC kibibytes, IEC mebibyte, IEC gibibyte, etc.
Selecting units for display of temperature, such as Fahrenheit, Celsius, or Kelvin.
Connecting the field to receive new content from a specified cell of the Black Board, or connecting the field to transmit its content to a specified cell of the Black Board.
Providing a larger Big Field in which to view or enter a number.
Providing an Expression field in which a mathematical expression can be entered and evaluated to a numeric value.
Providing editing controls such as Cut, Copy, Paste, and Delete.

Numeric fields which only display computed results, text entry fields, and text display fields, may provide some of the above options — accessed by right clicking the field.

Some numeric fields may have an associated, explicit, ''slider'' control in addition to the implicit ScrollPad. Right clicking the slider allows enlarging a portion of the slider's range for finer control.

Various windows of XCAP provide fields for entry of text, or file and path names. Right clicking the field yields an options menu. The options menu typically provides the following:

Connecting the field to receive new content from a specified cell of the Black Board, or connecting the field to transmit its content to a specified cell of the Black Board.
Providing a larger Big Field in which to view or enter text.
Providing a history of previously used values, allowing convenient reuse without retyping.
Providing editing controls such as Cut, Copy, Paste, and Delete.
Automatically generating a unique file name representing the current date and time (for files to be saved or created).

Various windows of XCAP provide fields for entry of pixel colors. Typically, the color can be entered numerically, and a small color ''swatch'' appears next to the color entry field, showing the selected color. Right clicking the swatch activates a color cylinder from which new colors may be selected by mouse clicks.

Various windows of XCAP provide a drop-down list selection field. Right clicking the selection field yields an options menu which in turn provides a Search feature. The Search allows convenient searching through a long list of selections. Selected drop-down list selection fields may have an explicit, adjacent, Search button to access the same service.

For drop-down list selection fields used to select a serial ''COM'' port (for Windows) or ''ttyS'' device (for Linux), right clicking the selection field yields an options menu which in turn provides a Refresh feature which updates the list based on the operating system's currently installed ports or devices.

Editing of numeric and text fields follows standard conventions. In brief, mouse click once or use left/right arrow keys to position the caret - characters are inserted at the caret as typed. Double mouse click to highlight all text or single click and drag to highlight a portion of text - a Delete or Backspace removes the highlighted text, a character replaces the highlighted text, and the left/right arrow keys cancel the highlight mode.

Hovering the mouse over a numeric, text, list selection, checkbox, radio button, button, or other control will cause the associated Tool Tip, if any, to pop-up; the Tool Tip will automatically disappear. The Tool Tip can also be displayed by right-clicking on the control for its options menu, which in turn provides a Tool Tip feature; the Tool Tip must be explicitly closed. The Big Field, Expression, and Search features also display the Tool Tip.

The user interface can be navigated without a mouse by using Tab and Shift-Tab to shift input focus, arrow keys and PgUp/PgDn to scroll, arrow keys to select tabs and list items, Enter to select choices and push buttons, and Alt-Tab (under Windows) or Ctrl-Alt-Tab (under Linux) to select a Window.

Optionally, if XCAP is intended to be used solely in conjunction with a TWAIN compliant application or with Image-Pro, many of the menu features of the Main Window and the PIXCI® Image Viewer Window may be removed so as to provide a simplified appearance (see Utilities - Program Setup). The same option also removes several PIXCI® Image Viewer - Capture - Shortcuts and adds shortcuts duplicating features of the PIXCI® - TWAIN Sourcery and Image-Pro Sourcery.

Notes: (A) For XCAP-Lite, the PIXCI® frame grabber is assumed installed and open for use, otherwise XCAP-Lite provides the same features as XCAP-Viewer. Use of XCAP-Plus, XCAP-Std, or XCAP-Ltd with missing authorization key provides the same features as XCAP-Lite. Use of XCAP without activation code, or never having been configured for an authorization key, provides the features of XCAP-Viewer.
(B) The Save, Import, and Export Graphic features are not available in XCAP-Viewer, XCAP-Lite, or XCAP-Ltd.
(C) For XCAP-Viewer, images may not be saved; images may not be loaded directly from an Internet URL. For XCAP-Lite, Save Image Sequence is only available in TIFF format; images may not be loaded directly from, or saved to, an Internet URL; and does not support image ''stack'' options.
(D) For XCAP-Lite, the Sequence Capture to Image Files only supports TIFF format.
(E) The maximum amount of frame buffer memory is dependent on a the characteristics of the PIXCI® imaging card, the operating system, and of XCAP software. The PIXCI® CL3SD and SI2 have on-board frame buffer memory, other PIXCI® imaging cards use computer based frame buffer memory. The PIXCI® CL1, CL2, D, D24, D32, D2X, D3X, SI, SV2, SV3, SV4, and SV5 are designed to access up to 4 GB of computer memory. The PIXCI® A110, A310, D3XE, E1, E1DB, E4, E4DB, E4G2-2F, E4G2-4B, E4G2-F2B, E4TX2-2F, E4TX2-4B, E4TX2-F2B, E8, E8CAM, E8DB, e104x4-2f, e104x4-4b, e104x4-f2b, EB1, EB1G2, EB1-PoCL, EB1G2-PoCL, EB1mini, miniH2B, miniH2F, miniH2x4F, mf2280, EC1, ECB1, ECB1-34, ECB2, EL1, EL1DB, ELS2, SI1, SI4, SV7, and SV8 are designed to access up to 16 EiByte of computer memory (a theoretical limit, as no currently available computer system provides 16 EiByte of memory). For XCAP-Lite, a maximum of 256 MiByte of computer based frame buffer memory is supported (but allows one full resolution image buffer w/out size restriction). On 32 bit systems, XCAP-Plus, XCAP-Std, and XCAP-Ltd support up to 4 GiBytes of computer based frame buffer memory. On 64 bit systems, XCAP-Plus and XCAP-Std supports up to 16 EiByte of computer based frame buffer memory; XCAP-Ltd supports up to 8 GiByte of computer based frame buffer memory. The maximum available computer based frame buffer memory is also limited by the computer hardware, configuration, and memory used by the operating system and other applications.
(F) Camera specific controls provided for cameras supported by PIXCI® E8CAM, ELS2, SI, SI1, SI2, and SI4, and for many digital cameras supported by PIXCI® CL1, CL2, CL3SD, D, D24, D32, D2X, D3X, D3XE, E1, E1DB, E4, E4DB, E4G2-2F, E4G2-4B, E4G2-F2B, E4TX2-2F, E4TX2-4B, E4TX2-F2B, E8, E8DB, e104x4-2f, e104x4-4b, e104x4-f2b, EB1, EB1G2, EB1-PoCL, EB1G2-PoCL, EB1mini, miniH2B, miniH2F, miniH2x4F, mf2280, EC1, ECB1, ECB1-34, ECB2, EL1, and EL1DB; the 'PIXCI® Camera Info' feature shows the specific, customized, support provided for each camera.
(G) For XCAP-Lite and XCAP-Viewer, the Palette feature does not include save, load, import, or export, nor the ''Extract Bright/Dark Reference'' features.
(H) The Save Data feature is not available in XCAP-Viewer.
(I) For XCAP-Lite and XCAP-Viewer, the Pixel Plot feature does not include statistics, save, export, or multi-image ''stack'' or ''plank'' options. For XCAP-Viewer, the Pixel Plot feature does not include printing.
(J) For XCAP-Ltd, XCAP-Lite, and XCAP-Viewer, the Modify, Set feature does not include non-rectangular regions.
(K) For XCAP-Ltd, XCAP-Lite, and XCAP-Viewer, the Measure features do not include calibration.
(L) For XCAP-Ltd, XCAP-Lite, and XCAP-Viewer, the Line Profile is limited to straight lines.
(M) Subject to the amount of frame buffer memory versus image resolution yielding more than one frame buffer.
(N) Software implemented White Balance and Color Corrections (in contrast to a camera's feature) is provided for SILICON VIDEO® and other selected cameras; XCAP-Lite provides automatic, continuous, white balance (AWB) only for SILICON VIDEO® cameras.

6. Getting Started with XCLIB

The optional XCLIB C/C++ library allows controlling the PIXCI® frame grabber from ''C/C++'' programs. Under Windows, the XCLIB library can also be accessed by any programming environment able to call functions within a DLL; such as VB.NET, C#, LabView, Matlab, and Python. Under Linux, the XCLIB library can also be accessed by any programming environment able to call functions within a Shared Object (SO); such as LabView, Matlab, and Python.

The XCLIB library is designed to be a component which is called by the user's application, rather than an application template with pre-selected and limited customizability. In other words, the XCLIB library forces the fewest possible architectural choices upon the user's application. Under Windows the XCLIB library is composed of ''C'' functions within a DLL and can be used from non-MFC, MFC, C#, or even ''console'' applications. With one optional exception, the XCLIB library does not create any windows or dialogs of its own; rather it allows displaying imagery into a window provided by the user.

This quick introduction focuses primarily on XCLIB library functions themselves; programming environment, operating system issues, and compilation instructions are addressed in the XCLIB Reference Manual and in the example programs provided with the XCLIB library. Nor is this introduction intended to cover every XCLIB library function or to provide complete programs; rather it is intended to provide the ''feel'' of XCLIB library programming, without the complications of user interfaces and application specific functionality.

Alternatives to use of XCLIB are available. The Media Foundation Frame Server (DirectShow) driver for PIXCI® frame grabbers provides a Windows Media Foundation, Media Source driver to control PIXCI® frame grabbers and retrieve video and image data. The Video for Linux Driver (V4L2) for PIXCI® frame grabbers provides a Linux standard V4L2 API to control PIXCI® frame grabbers and retrieve video and image data.

6.1. XCLIB Architecture Overview

The XCLIB library has two series of functions. The Simple C Functions (SCF), whose names start with pxd_, suffice for most application programs. This introduction only discusses the SCF functions.

Frame buffers are preallocated by the library, and selected by ordinals 1, 2, etc. The number of frame buffers is dependent on the camera resolution and the total memory size reserved for frame buffers. Under Windows and Linux, the reserved memory size can easily be set in XCAP application's Driver Assistant, or by following the installation instructions.

Functions to snap a video field or frame (such as pxd_goSnap, discussed below) capture the next video field or frame following its invocation. In other words, the function ''arms'' the PIXCI® frame grabber to capture the next video field or frame into a frame buffer. This is in contrast to having the frame grabber consume resources continuously capturing everything, and having a hypothetical snap function retrieve the last field or frame captured. This hypothetical behavior can be obtained in XCLIB using pxd_goLivePair (also discussed below) or similar functions, but it is not the behavior of the snap function.

6.2. The Simplest XCLIB Program

The following code captures an image into the first frame buffer with the frame grabber and camera in the default mode:

    #include "xcliball.h"
        ...
    pxd_PIXCIopen("",           // driver configuration parameters: use default
                  "Default",    // video format name: use default as per specific frame grabber
                  "");          // video setup file exported by XCAP: none
    pxd_doSnap(0x1,             // select PIXCI(R) unit 1
               1,               // select frame buffer 1
               0);              // default timeout
    pxd_PIXCIclose();

For a shorter program, under Windows and Linux (but not DOS) the:

    pxd_PIXCIclose();

may be eliminated, but for the sake of robustness and portability including the pxd_PIXCIclose is recommended.

A note on syntax for users of languages other than C/C++. A string of characters in C/C++ is denoted by " characters; a "" represents the empty string. XCLIB doesn't expect the " characters. Use whatever syntax is required by the current language to provide the characters shown within the "" characters.

For PIXCI® A310 frame grabber, the pxd_PIXCIopen parameter ''RS-170'' selects the RS-170 format. Some of the other choices are ''CCIR'', ''Video 1920x1080i 60Hz'', ''Video 1920x1080i 50Hz'', ''Video 1920x1080p 60Hz'', ''Video 1920x1080p 50Hz'', ''Video 1280x720p 50Hz'', ''Video 1280x720p 60Hz'', ''Video 1280x720p 60Hz RGB''. ''Video 720x480i 60Hz RGB'', ''Video 720x576i 50Hz RGB'', ''Video 640x480i 60Hz RGB'', ''Video 768x576i 50Hz RGB'', ''Video 1920x1080i 60Hz RGB'', ''Video 1920x1080i 50Hz RGB'', ''Video 1920x1080p 60Hz RGB'', ''Video 1920x1080p 50Hz RGB'', and ''Video 1280x720p 50Hz RGB''.

The pxd_PIXCIopen parameter ''Default'' selects one of the above formats as coded into the PIXCI® frame grabber's EEPROM.

Or, after configuring the XCAP application to the desired format, a video setup file can be exported and its path name specified as the third parameter to pxd_PIXCIopen.

A slightly longer program that does something useful with the captured image:

    #include "xcliball.h"
        ...
    pxd_PIXCIopen("", "Default", "");
    pxd_doSnap(0x1, 1, 0);
    pxd_saveTiff(0x1,           // select PIXCI(R) unit 1
                 "image.tif",   // pathname
                 1,             // select frame buffer 1
                 0, 0,          // upper left X, Y AOI of buffer
                 -1, -1,        // lower right X, Y AOI of buffer,
                                // -1 is an abbreviation for the maximum X or Y
                 0, 0);         // reserved
    pxd_PIXCIclose();

which saves the captured image to a file. Or:

    #include "xcliball.h"
        ...
    pxd_PIXCIopen("", "",  "/user/application/myVideoSetup.fmt");
    pxd_doSnap(0x1, 1, 0);
    {
        void *buf = malloc(  pxd_imageXdim()    // horizontal resolution
                           * pxd_imageYdim()    // vertical resolution
                           * sizeof(short));

        pxd_readushort(0x1,         // select PIXCI(R) unit 1
                       1,           // select frame buffer 1
                       0, 0,        // upper left X, Y AOI of buffer
                       -1, -1,      // lower right X, Y AOI of buffer,
                                    // -1 is an abbreviation for the maximum X or Y
                       buf,         // program buffer to be filled
                       pxd_imageXdim() * pxd_imageYdim(),
                                    // size of program buffer in short's
                       "Grey");     // color space to access
        .. process data ..
        free(buf);
    }
    pxd_PIXCIclose();

which copies the captured image into a program buffer. Both pxd_saveTiff and pxd_readushort allow saving or reading from an area of interest (AOI) of the captured image. The latter example also shows use of a video setup file exported by the XCAP application. (Use of a solidus (''/'') instead of reverse solidus (''\'') is allowed by all operating systems and avoids any complications of C/C++ treating the latter as a special character).

The XCLIB library provides data conversions, ''unsigned char'' versus ''unsigned short'', as necessary, as well as color space conversions. Thus, pxd_readushort will work with 8, 10, or 12 bit pixels, enlarging 8 bit pixels to unsigned shorts (right justified). And the similar pxd_readuchar also works with 8, 10, or 12 bit pixels, truncating 10 or 12 bit pixels to unsigned chars (keeping the most significant bits).

Similarly, these functions convert color spaces as needed; in the example above, correct grey level data is provided regardless of whether the captured image is monochrome or RGB.

The XCLIB-Lite library does not provide data size or color space conversions. For data size and color space dependent access to pixel data the pixel size, resolution and color space can be queried:

    ..
    pxd_doSnap(0x1, 1, 0);
    {
        void *buf = malloc(  pxd_imageXdim()    // horizontal resolution
                           * pxd_imageYdim()    // vertical resolution
                           * (pxd_imageBdim()>8? sizeof(short): sizeof(char))
                                                // bit depth
                           * pxd_imageCdim());  // number of color components

        if (pxd_imageBdim() <= 8)
            pxd_readuchar(0x1, 1, 0, 0, -1, -1, buf,
                          pxd_imageXdim() * pxd_imageYdim() * pxd_imageCdim(),
                          pxd_imageCdim()==1? "Grey": "RGB");
        else
            pxd_readushort(0x1, 1, 0, 0, -1, -1, buf,
                          pxd_imageXdim() * pxd_imageYdim() * pxd_imageCdim(),
                          pxd_imageCdim()==1? "Grey": "RGB");
        .. process data ..
        free(buf);
    }

In practice, most application programs are designed for a specific camera and resolution, and the above code can be simplified by using only the relevant pxd_readuchar or pxd_readushort.

6.3. XCLIB Error Detection

Every real application should check for errors. Most XCLIB library functions return an integer value, with values less than 0 indicating an error. The pxd_mesgErrorCode function provides a textual description for each error:

    int     r;
    r = pxd_saveTiff(0x1, "image.tif", 1, 0, 0, -1, -1, 0, 0);
    if (r < 0) {
        // For Windows GUI
        MessageBox(NULL, pxd_mesgErrorCode(r)), "XCLIB Error", MB_OK|MB_TASKMODAL);
        // For Windows Console, DOS, Linux
        printf("XCLIB Error: %s\n", pxd_mesgErrorCode(r));
    }

In addition, the pxd_mesgFault provides a detailed report for errors occurring during pxd_PIXCIopen and video capture functions.

    int     r;
    r = pxd_PIXCIopen("", "Default", "");
    if (r < 0)
        pxd_mesgFault(0x1); // select PIXCI(R) unit 1

Under Windows, the pxd_mesgFault pops up a dialog. Under DOS or Linux it displays error information to ''stderr''.

Hereafter, for the sake of brevity and clarity, error checking will not be shown.

Any of the predefined format names can be selected as the second parameter to pxd_PIXCIopen using, for example:

    pxd_PIXCIopen("", "RS-170", "");
or
    pxd_PIXCIopen("", "CCIR", "");

Using:

    pxd_PIXCIopen("", "Default", "");

selects one of the above selections, as coded into the PIXCI® A310 frame grabber's EEPROM. If no selection is coded, the capture resolution is set for 888 pixels per line by 888 lines.

To capture an AOI of the camera's field of view so as to obtain more frame buffers within a given amount of memory:

Using XCAP, configure the desired format and resolution.
Use:
```
    PIXCI®
    PIXCI® Export Video Setup
```
to save the video setup to a specified file name.
Use:
```
    pxd_PIXCIopen("", "", "/user/application/myVideoSetup.fmt");
```
to open XCLIB with the same video setup. The third parameter can be a fully qualified path name or a file name; if the latter, the standard operating system default determines what directory (folder) is expected to contain the file name. (Use of a solidus (''/'') instead of reverse solidus (''\'') is allowed by all operating systems, and avoids any complications of C/C++ treating the latter as a special character).
Alternately, the pxd_videoFormatAsIncluded allow switching the video setup without re-opening XCLIB, as well as compiling the video setup file into the application. See the XCLIB Reference Manual for more information.

6.5. More Video Capture Modes

The:

    pxd_doSnap(...);

is the easiest function for capturing single images; the programmer specifies the buffer and the function returns when the capture is completed.

Other capture functions return immediately, allowing the application to proceed with other tasks without having to utilize multiple execution threads. The:

    pxd_goSnap(0x1, // select PIXCI(R) unit 1
               1);  // select frame buffer 1

initiates capture of a single video field or frame into the specified buffer, the:

    pxd_goLive(0x1, // select PIXCI(R) unit 1
               1);  // select frame buffer 1

initiates continuous capture of each video field or frame into the specified buffer, the:

    pxd_goLivePair(0x1, // select PIXCI(R) unit 1
                   1,   // select frame buffer 1
                   2);  // select frame buffer 2

initiates continuous captured of each video field or frame into alternate buffers, the:

    pxd_goLiveSeq(0x1               // select PIXCI(R) unit 1
                  1,                // select start frame buffer 1
                  pxd_imageZdim(),  // select end as last frame buffer
                  1,                // incrementing by one buffer
                  pxd_imageZdim(),  // once per buffer
                  1);               // advancing to the next buffer after each frame

initiates capture at video rate of ten fields or frames into ten buffers, and finally the:

    pxd_goLiveSeq(0x1               // select PIXCI(R) unit 1
                  1,                // select start frame buffer 1
                  pxd_imageZdim(),  // select end as last frame buffer
                  1,                // incrementing by one buffer
                  0,                // for ever
                  1);               // advancing to next buffer after each 1 frame

initiates continuous capturing of video fields or frames at video rate into a ''ring'' composed of all frame buffers.

For use along with capture functions that run in the ''background'' are functions to monitor their progress. For example:

    pxd_goSnap(0x1, 1);
    for (;;) {
        if (!pxd_goneLive(0x1, 0))
            break;
        .. do some useful work while waiting..
    }

is one method of checking whether the previous pxd_goSnap is done. Or,

    pxbuffer_t  last = -1;

    pxd_goLivePair(0x1, 1, 2);
    for (;;) {
        if (pxd_capturedBuffer(0x1) == last)
            continue;   // nothing new captured yet
        last = pxd_capturedBuffer(0x1);
        .. process last captured image ..
    }

continuously captures into a pair of buffers, processing each video field or frame as the next is being captured and can also be used with pxd_goLiveSeq().

Of course, many applications prefer to avoid ''polling'' for status within a loop. The XCLIB library also provides asynchronous notification of both:

A field has arrived from the camera (whether PIXCI® frame grabber was instructed to capture it or not), and
A field or frame has been captured.

In Windows these notifications take the form of an ''Event'', in DOS these notifications take the form of a callback function, and in Linux these notifications take the form of a ''signal''. For example, under Windows:

    HANDLE event = pxd_eventCapturedFieldCreate(0x1);   // select PIXCI(R) unit 1

Thereafter, any thread waiting upon the event will be notified whenever a field has been captured by pxd_goSnap, pxd_goLive, pxd_goLivePair, pxd_goLiveSeq, or by the pxd_goLiveTrig discussed below.

The pxd_goLivePair or pxd_goLiveSeq start the video engine to continuously and automatically fill the ring of frame buffers; the application monitors progress and must read data from a frame buffer before being overwritten by the video engine. An alternative approach is to queue empty frame buffers which are to be filled by the DMA engine:

    pxbuffer_t  last = -1;
    pxd_quLive(0x1, 1); // add buffer 1 to video engine queue
    pxd_quLive(0x1, 2); // add buffer 2 to video engine queue
    for (;;) {
        if (pxd_capturedBuffer(0x1) == last)
            continue;   // nothing new captured yet
        last = pxd_capturedBuffer(0x1);
        .. process last captured image ..
        pxd_quLive(0x1, last);  // re-add buffer to video engine queue
    }

The application monitors progress and must read data and re-queue each frame buffer; if no frame buffer is queued the video engine skips capture of a frame. Both approaches share the same performance - video, bus, and CPU efficiency; they differ as to what is captured when the application falls behind its processing of image data.

6.6. PIXCI® A310 Triggered Capture

Cameras used with the PIXCI® A310 frame grabber free-run; continuously exposing and sending fields or frames to the frame grabber. Triggering consists of selecting a field or frame to capture; the camera does not support adjusting the exposure in response to a trigger.

A simple trigger example using the general purpose level sensitive inputs, is:

    int odata;
    odata = pxd_getGPIn(0x1,    // select PIXCI(R) unit 1
                        0);     // reserved
    while (odata == pxd_getGPIn(0x1, 0))
        ;                       // wait for trigger
    pxd_doSnap(0x1, 1, 0);

which waits until any of the general purpose inputs have changed, then snaps the next field or frame arriving from the camera.

Or,

    int odata = pxd_getGPIn(0x1, 0);    // save current G.P inputs
    pxd_goLive(0x1, 1);                 // capture continuously
    pxd_setGPout(0x1, 0x01);            // set output flag that we are ready
    while (odata == pxd_getGPIn(0x1, 0))
        ;                               // wait for trigger
    pxd_setGPout(0x1, 0x02);            // set output flag that we saw the trigger
    pxd_goUnLive(0x1);                  // terminate continuous capture
    while pxd_goneLive(0x1, 0))         // wait for capture to cease
        ;
    pxd_setGPout(0x1, 0x04);            // set output flag that we are done

This variation captures the field or frame which was being sent while the trigger was received; the former example captures the field or frame following the trigger. It also demonstrates use of the general purpose outputs for ''handshaking'' with any external equipment.

Both of these examples depend on the application responding to the general purpose input in a timely manner, and both consume time in wait loops. Neither is a significant problem under single-tasking DOS, but can be a problem under multi-tasking Windows or Linux depending upon how much latency the application allows and what other tasks are running.

Alternately, the pxd_goLiveTrig described in the XCLIB Reference Manual performs the same function as the latter example including use of general purpose output ''strobes'', but returns immediately leaving the trigger capture running in the ''background''. It also provides minimal latency and additional options for delaying the capture following the trigger by a specified number of fields or frames.

Triggering can also be done using the general purpose edge sensitive trigger:

    int ocnt = pxd_getGPTrigger(0x1, 0);        // save current trigger count
    while (ocnt == pxd_getGPTrigger(0x1, 0))    // wait for change
        ;
    pxd_doSnap(0x1, 1, 0);                      // snap

    int ocnt = pxd_getGPTrigger(0x1, 0);        // save current trigger count
    pxd_goLive(0x1, 1);                         // capture continuously
    while (ocnt == pxd_getGPTrigger(0x1, 0))    // wait for change
        ;
    pxd_goUnLive(0x1);                          // terminate continuous capture
    while pxd_goneLive(0x1, 0))                 // wait for capture to cease
        ;

For applications which prefer to avoid ''polling'' for status within a loop, XCLIB also provides asynchronous notification of the general purpose trigger. As for video field notifications, in Windows these notifications take the form of an ''Event'', in DOS these notifications take the form of a callback function, and in Linux these notifications take the form of a ''signal''. For example, under Windows:

    HANDLE event = pxd_eventGPTriggerCreate(0x1, 0, 0);   // select PIXCI(R) unit 1

Thereafter, any thread waiting upon the event will be notified upon the general purpose trigger, and can then do a pxd_goSnap or pxd_goUnLive, as appropriate.

6.7. PIXCI® A310 Triggered Sequence Capture

As described above, cameras used with the PIXCI® A310 free-run; continuously exposing and sending fields or frames to the frame grabber. Triggering consists of selecting a field or frame on which to start or end capture.

For example:

    int odata;
    odata = pxd_getGPIn(0x1,        // select PIXCI(R) unit 1
                        0);         // reserved
    while (odata == pxd_getGPIn(0x1, 0))
        ;                           // wait for trigger
    pxd_goLiveSeq(0x1               // select PIXCI(R) unit 1
                  1,                // select start frame buffer 1
                  pxd_imageZdim(),  // select end as last frame buffer
                  1,                // incrementing by one buffer
                  pxd_imageZdim(),  // for this many captures
                  1);               // advancing to next buffer after each 1 frame
    while pxd_goneLive(0x1, 0))     // wait for capture to cease
        ;

which waits until any of the general purpose inputs have changed, then fills the frame buffers with fields or frames at video rate.

Or,

    int odata = pxd_getGPIn(0x1, 0);
    pxd_goLiveSeq(0x1               // select PIXCI(R) unit 1
                  1,                // select start frame buffer 1
                  pxd_imageZdim(),  // select end as last frame buffer
                  1,                // incrementing by one buffer
                  0,                // for ever
                  1);               // advancing to next buffer after each 1 frame
    while (odata == pxd_getGPIn(0x1, 0))
        ;                           // wait for trigger
    pxd_goUnlive(0x1);
    while pxd_goneLive(0x1, 0))     // wait for capture to cease
        ;
    printf("Most recent captured buffer: %d\n", pxd_capturedBuffer(0x1);

which continuously captures until the trigger arrives, leaving the frame buffers filled with video fields or frames that predate the trigger.

Or,

    int         odata = pxd_getGPIn(0x1, 0);
    pxvbtime_t  fieldcount;
    pxd_goLiveSeq(0x1               // select PIXCI(R) unit 1
                  1,                // select start frame buffer 1
                  pxd_imageZdim(),  // select end as last frame buffer
                  1,                // incrementing by one buffer
                  0,                // for ever
                  1);               // advancing to next buffer after each 1 frame
    while (odata == pxd_getGPIn(0x1, 0))
        ;
    fieldcount = pxd_videoFieldCount(0x1);  // get current value of field counter
    while (pxd_videoFieldCount(0x1) < fieldcount+(pxd_imageZdim()/2)*pxd_imageIdim())
        ;
    pxd_goUnlive(0x1);
    while pxd_goneLive(0x1, 0))     // wait for capture to cease
        ;
    printf("Most recent captured buffer: %d\n", pxd_capturedBuffer(0x1);

which continuously captures until the trigger arrives, waits for half of the frame buffers to be filled following the trigger, then terminates capture. The captured result is half of the frame buffers predate the trigger and half postdate the trigger.

8. In Case of Trouble

If problems are encountered during operation of the PIXCI® frame grabber, an error message may appear in the center of the XCAP main window, or a Message Log window may appear in the upper-right corner of the XCAP main window containing an error message, or if using XCLIB an error message window may appear. If using the XCLIB library, display of the error message is under control of the user's application. To help resolve any problems, it is recommended to first read the frequently asked questions (FAQ) posted on the support page of the EPIX, Inc. website. The FAQ addresses several of the most commonly encountered problems. Highly detailed computer configuration tips are available by selecting PC Configuration Tips from the Help menu in the XCAP main window.

Third party applications using XCLIB may choose not to display error messages. So as to assist providing technical support, error messages describing a fault on open of the PIXCI® frame grabber are automatically logged to the Windows Event Log (for Windows 2000 and later) or the Linux syslog.

Below are listed all of the potential errors that may be encountered, along with a brief description of the error and brief summary of how to resolve the error condition.

The specified DPMI operation code failed. Only occurs under DOS.

Driver/Library Interface Phase Error! (NN:NN:NN)!

Contact EPIX, Inc. Technical Support.

Driver access denied: ... !

For Linux. The driver module appears to be installed (and is listed by ''lsmod''), but the /dev/pixci node may not exist, have the wrong major or minor numbers, or have the wrong permissions. Generally, occurs only when alternate methods or scripts (other than those provided by EPIX, Inc.) have been used to install the driver.

Driver installed ... version is incompatible with library ... !

Self explanatory.

Driver installed ... is wrong version - requires ... !

Deprecated. Self explanatory.

Driver not installed - requires ... or frame grabber not installed!

Generally self explanatory.

Note that on Windows systems supporting Plug & Play (i.e. other than Windows NT), the driver will only be installed if a PIXCI® frame grabber is detected. Use the Windows' Device Manager (run ''devmgmt.msc'') to distinguish whether a PIXCI® frame grabber isn't installed versus the driver not installed. Error can also occur on Windows 2K and later if using a newer V3.8.1 driver with an older DLL, as the driver was modified to pass Microsoft's ''style'' checks; a driver registry option provides for backward compatibility.

On Linux, the driver is installed during boot. When compiled with current default options, the driver remains installed regardless of whether the PIXCI® frame grabber is detected. Compiled with backward-compatible options, the driver will remain installed only if a PIXCI® frame grabber is detected; run ''lspci'' to distinguish whether the driver wasn't installed upon boot versus a PIXCI® frame grabber isn't installed.^[8]

8.2. Run-Time Error Messages

The following error messages are reported when a fault occurs during operation of the PIXCI® frame grabber.

Invalid frame buffer number! (.../...)!: A frame buffer number, larger than the current number of frame buffers, was specified for capture. Most likely an error by application software.
Unable to record frame buffer status & time stamp! (buffer/s=NN/NN)!: The frame buffer memory is not writable from the interrupt handler. Typically occurs when using forceful memory allocation. Set the ''Per Frame-Buffer Status: Use System Memory'' (in PIXCI®, PIXCI® Open/Close, Advanced) option.
Video not captured! (Image Adrs FIFO)!: Contact EPIX, Inc. Technical Support.
Video not captured! (PCI Bus Error NN)!: During video capture via DMA, the PCI Express bus logged an error. Contact EPIX, Inc. Technical Support.
Video not captured! (PCI FIFO Overflow)!: The bandwidth provided by the PCI Express bus is insufficient for capturing video-rate data. Updating the computer's firmware and BIOS, trying a different PCI slot, and disabling power conservation features in BIOS may increase the bandwidth provided by the bus. Reduce the horizontal capture resolution, reduce the capture bit depth, or, if capturing 10 bits per pixel, enable use of bit-packing, to decrease the bandwidth required.

10. Glossary

Active Video

Portion of an analog video signal which contains information on intensity and color; i.e the viewable portion.

By analogy, the term may be used with digital video signals: the portion of signal(s) containing useful pixel values as indicated by the ''Line Valid'' and ''Frame Valid'' signals.

AOI

Area of interest. An area of an image subject to modification, loading, saving, printing, etc. Typically, within EPIX® imaging software, when used in conjunction with, or contrasted against, the term ''ROI'': an AOI is rectangular, with sides parallel to the image axis while an ROI is any other closed geometric shape or orientation. However, there is no industry standard for use of AOI vs ROI, and within EPIX® imaging software various camera specific controls typically follow the conventions of each camera's manufacturer.

An AOI is sometimes referred to as a ''window'' within the image, but is not to be confused with a ''window'' or ''dialog'' of a Graphical User Interface, such as Windows^tm, Java^tm, or GTK.

Analog Camera

A video camera which outputs pixel intensities (imagery) and timing or synchronization information as one or more continuously varying electrical signals. A camera with analog output might contain an analog sensor or a digital sensor.

Analog Gain

Amplification of the analog pixel intensity signal so as to modify the resulting pixel values. Ideal analog gain would multiply the pixel intensity by a constant without addition of noise. In practice, analog gain adds a random noise component which is independent of pixel intensity, and adds a random noise component which increases, perhaps non-linearly, for higher pixel intensities. Typically, both noise components increase for higher levels of gain.

In contrast to ''Digital Gain'', use of analog gain on dim pixel intensities will, typically, produce an image with both greater contrast and greater continuous tonality, albeit with increased levels of random noise.

Aperture (Lens)

The opening, often of adjustable diameter, through which light enters into the camera.

Area of Interest

See ''AOI''.

Area Scan

A method of image acquisition which uses a two-dimensional array of photo sensitive elements or a two-dimensional photo sensitive surface.

Aspect Ratio

The ratio of a pixel's width to height, or the ratio of an image's width to height; the two are not equivalent, but can be related given the image's horizontal and vertical resolution. Image analysis and measurement is simplified by having square pixels - the real world distance represented by a given number pixels is the same whether extended horizontally or vertically. An image might consist of square pixels but with different horizontal and vertical resolution; resulting in a non-square image aspect ratio, but is still convenient for image analysis and measurement.

Authorization Key

Small device which must be connected to a computer, typically via the parallel port or USB port, to enable use of software protected against unauthorized duplication.

AVI (.AVI)

The Audio-Video Interleaved, multi-media, image file format specified by Microsoft for use with Windows. Can contain sequences of images within a single file. AVI 1.0 files may be as large as 4 GiByte, however, some programs may not be able to read AVI 1.0 files larger than 2 GiByte. AVI 2.0 files may be larger than 4 GiByte.

Back Focus (Adjustment)

A mechanical adjustment within a camera to change the distance from the lens' back mounting flange to the image sensor. Adjustment may be required if, due to manufacturing tolerances, a lens set to a given object distance does not focus on an object at that distance. Adjustment may also be required when switching between visible and infrared illumination.

Back Porch

The portion of an analog video signal which follows the rising edge of the horizontal sync and precedes the active video.

Bayer Pattern

A 2×2 mosaic of red, green, green, and blue filters:

          . . . .
    ...  R  G  R  G  ...
    ...  G  B  G  B  ...
    ...  R  G  R  G  ...
    ...  G  B  G  B  ...
          . . . .

which cover the photosites of some CCD or CMOS image sensors. There are four possible alignments of the mosaic with the image's upper left photosite; a particular alignment is often referred to as ''Bayer Phase''. A color RGB image is constructed by interpolating the pixel values derived from photosites under the various filters.

BigTIFF

An extension to the Tagged Image File Format (TIFF) for saving digital images and image sequences; BigTIFF files may be as large as 16 EiByte (2⁶⁴ bytes). BigTIFF is not as widely supported as the TIFF format.

Bit

The smallest, fundamental, unit of binary data.

Bits per Pixel

Number of bits assigned to represent grey intensity (or level), or luminance and chrominance intensity (or level), information in a single pixel. Indirectly, the number of different discrete levels that represent the variations of such information. For example, 8 bits per pixel yields 256 distinct grey levels.

For color pixels, the number of bits may refer to the number of bits per color component, or to the total number of bits for all components; ''16 bit RGB'' may refer to an older S/VGA standard that provides low quality color by using 5 or 6 bits for red, blue, and green, or may refer to high quality color using a total 48 bits per pixel and providing 65536 intensity levels for each of red, green, and blue.

BGR Color

Same as ''RGB Color'', with the order changed to blue, green, and red.

Black Level (Control)

Same as ''Brightness (Control)''.

BMP (.BMP)

The BitMaP image file format specified by Microsoft for use with Windows for saving graphics and digital images.

Brightness (Control)

A parameter to modify the image's brightness - the average pixel value. Typically, a brightness control modifies the image by adding or subtracting a constant from (digital) pixel values or (analog) pixel intensities.

Buffer

RAM or other memory used to store data. See ''Image Buffer'', ''Frame Buffer''.

Capture

To convert a field or frame of video into pixel values stored in a frame buffer.

Camera Link

A standard for a high performance serial data interface using an 11 pair conductor cable and the MDR 26-pin connector, or the smaller SDR 26-pin connector, intended for the connection of digital cameras to frame grabbers. Camera Link utilizes the Channel Link interface and chips for transmission of pixel data and video timing, and utilizes LVDS for transmission of serial data and other signals. The cable length is limited to 10 meters; however, some cameras operating with higher pixel clock rates may specify a shorter maximum length; some thinner or more flexible cables may also specify a shorter maximum length. The cable may be effectively extended by use of a repeater.

The Base Configuration uses one Channel Link chip, one MDR or SDR 26-pin connector, and can transfer 24 pixel bits per clock, such as 8×1, 8×2, 8×3, 10×1, 10×2, 12×1, 12×2, 14×1, 16×1 monochrome or Bayer color, and 8×3 RGB color. The Medium Configuration uses two Channel Link chips, two MDR or SDR 26-pin connectors and can transfer 48 pixel bits per clock, such as 8×4, 10×3, 10×4, 12×3, 12×4 monochrome or Bayer color, and 10×3, 12×3 RGB color. The Full Configuration uses three Channel Link chips, two MDR or SDR 26-pin connectors and can transfer 64 pixel bits per clock, such as 8×8 monochrome or Bayer color. The 80-Bit Configuration (formerly referred to as Expanded Configuration, Extended Configuration, Full Plus Configuration or Deca Configuration), uses three Channel Link chips, two MDR or SDR 26-pin connectors and can transfer 80 pixel bits per clock, such as 8×10 or 10×8 monochrome or Bayer color.

The standard provides for four trigger/control signals, ''CC1'', ''CC2'', ''CC3'', and ''CC4''.

Camera Link DLL

A standardized API (Application Program Interface) that provides serial transport functions; i.e. to send a string of characters (bytes) or receive a string of characters (bytes). The standard does not specify how strings (bytes) are to be formatted into commands or responses; each camera manufacturer, or each camera, specifies its own syntax and semantics. Camera Link DLLs are assigned clserXXX.DLL names, where ''XXX'' is a unique frame grabber identifier or frame grabber manufacturer identifier. The Camera Link DLL for PIXCI® frame grabbers is named clserEPX.DLL.

Camera Link Lite

A standard for a high performance serial data interface using a 7 pair conductor cable and SDR 14 pin connector, intended for the connection of digital cameras to frame grabbers and can transfer 10 pixel bits per clock, such as 8×1 or 10×1 monochrome or Bayer color. The standard provides for a single trigger/control signal, ''CC1''.

CCIR

Consultative Committee International Radio. The European video standard for monochrome television transmission which specifies 625 lines per frame, divided into two interlaced fields, and a 25 Hz frame rate.

Channel Link

A standard for a high performance serial data interface using a 9 or 11 conductor cable and operating at speeds of 840 to 1848 megabits per second, developed by National Semiconductor which provides Channel Link interface chips.

Chroma Key

A rule for combining two video signals, or two images, based on the color of one image, such as: The output signal/image is taken from signal/image A, except where A contains the chroma key value, where the output is taken from signal/image B, allowing signal/image A and B to be overlaid, with A's chroma key pixels effectively transparent.

Clamping (in Analog Video)

The process of restoring a DC reference level which was removed to make an AC coupled signal. Without a known DC reference level, an analog video waveform can't be digitized correctly.

Clipping

Limiting a signal or numeric value, such as pixel intensity to not be below a limit and/or not be above a limit. For example: Eight bit pixel values are limited to be between values 0 and 255, inclusive; a pixel intensity greater than the intensity which corresponds to value 255 must be limited to value 255. Clipping pixel values introduces non-linear errors; non-linear errors cause problems with color correction, PRNU and DSNU correction, intensity based image measurements, and other features.

C-Mount Lens

A lens specification in which the mounting threads are 1 inch diameter with 32 threads per inch, and a distance of 17.526 mm from the lens' back mounting flange to the image sensor. The similar ''CS-Mount'' lens specification has the same mounting threads but with a distance of 12.526 mm from the lens' back mounting flange to the image sensor.

CMY Color

Color space composed of three components: cyan, magenta, and yellow. CMY and RGB are easily related: cyan is the complement of red, magenta the complement of green, and yellow the complement of blue. Alternately, red is the complement of cyan, green the complement of magenta, and blue the complement of yellow.

CMYK Color

Color space composed of four components: cyan, magenta, yellow, and black. The ''natural'' color space for printing and graphic arts, as so-called ''four color'' material is printed using combinations of cyan, magenta, yellow, and black inks.

Color Temperature

The spectrum of illumination produced by an ideal blackbody which is at a specified temperature in degrees Kelvin. Often used synonymously with Correlated Color Temperature which is the color temperature of a black body whose perceived color is most closely matched by a whitish illuminate, as judged by a human observer. Lower temperature illuminators such as tungsten lamps at 2800°K to 3000°K radiate more reddish (lower energy) wavelengths, higher temperature illuminators such as cool white fluorescent lamps at 4100°K to 4300°K radiate more bluish (higher energy) wavelengths. The color temperature of natural illumination - sunlight on planet Earth - varies depending on the season, time of day, and degree of cloud cover; typical values are 5000°K for sunrise & sunset daylight, 6500°K for noon daylight, and 7500°K for overcast daylight.

Color Camera, One Chip

A color camera with a single solid state imaging sensor in which the sensor's photosites are covered with different colored filters. Typically a pattern of red, green, and blue filters is used. Each color pixel is created by combining values from three or more adjacent photosites. Contrast to ''Color Camera, Three Chip''.

Color Camera, Three Chip

A color camera with three solid state imaging sensors in which through the use of filters or other optical means, each sensor is exposed to a narrow color band of the full field of view. Typically, the sensors are exposed to reddish, greenish, and bluish colors (as typical filters are wideband and admit colors other than pure red, green, and blue). Each color pixel is created by combining one value from corresponding photosites of each of the three imaging sensors. Contrast to ''Color Camera, One Chip''.

Color Gamut

Color range attainable by a display monitor or other media. The color gamut of a display monitor is dependent on the CRT's phosphor coating, or the LCD's filters and illuminant. A printed image's color gamut is dependent on the inks and paper.

Color Key

See ''Chroma''Key"''.''

Color Lookup Table

An association between each possible value of an index pixel and (typically) an RGB color.

Composite Video

Analog video signal which combines active video, sync, and blanking into a single waveform. Examples include RS-170, NTSC, PAL, CCIR, and RS-343.

Compression

Reduction in the size of a image, usually in conjunction with being saved to disk or transmitted. See Lossy Compression and Lossless Compression.

Contrast

A measure of the relative intensity differences within an image. A low contrast image may be dark (e.g. a foggy night), or bright (e.g. a foggy day); a high contrast image has both bright and dark areas. Typically, the difference between an image's lightest and darkest grey level value.

Contrast (Control)

A parameter to modify the image's contrast - the difference between the brightest and darkest pixels. Typically, a contrast control modifies the image by multiplication of (digital) pixel values, or (analog) pixel intensities, with a constant.

Instead of multiplying pixel values (V) by a constant (C):

V*C

which leaves the 0 value pixel unchanged, image processing algorithms may instead use:

    (V-(M/2))*C + (M/2)

where (M) is the maximum pixel value and leaves mid-value pixels unchanged. In this context, the former equation may be referred to as ''Gain'' and the latter as ''Contrast''. In other contexts, ''Gain'' and ''Contrast'' are synonyms.

Controlled (Video) Mode

A camera mode in which the camera is normally quiescent; that is, not continuously and autonomously exposing photosites and outputting the corresponding pixel values. Upon receiving an external trigger signal or command, the camera exposes and outputs a specified number of images, typically one, and resumes its quiescent state. The ''Controlled (Video) Mode'' allows synchronizing the camera's exposure to an external event, such as when an object obstructs a photoelectric sensor. The ''Controlled (Video) Mode'' also allows synchronizing two or more cameras, by use of a common external trigger signal. Contrast to ''Free-Run (Video) Mode''.

In ''Controlled (Video) Mode'' some cameras can overlap exposure of the next frame with output of the current frame, yielding the same frame rate as in free-run mode (assuming that the exposure period isn't longer than the output period). In other cameras, the exposure and output are sequential; the frame rate decreases as the exposure increases, and a frame rate near that of free-run mode is achieved only as the exposure period approaches zero.

Different camera manufacturers use various synonyms, such as ''Frame on Demand Mode'', ''Triggered (Video) Mode'', ''External Triggered (Video) Mode'', ''External Sync (Video) Mode'', ''Single Shot (Video) Mode'', ''Controlled (Video) Mode'', or ''Async Shutter (Video) Mode''.

CRT

Cathode Ray Tube. An older technology for display monitors and televisions, using an electron gun, magnetic or electrostatic deflection, and phosphors, coating the display surface, that fluoresce when struct by the electron beam.

CS-Mount Lens

See ''C-Mount Lens''.

Digital Camera

A camera which outputs pixel intensities (imagery) and timing or synchronization information as discrete data.

Digital Gain

Modifies pixel values by multiplying, or scaling, the digital pixel value by a constant. Any noise in the pixel values is scaled up, or down, in the same proportion as the original pixel values.

Digital gain can make a dim image more pleasant to view, but can't introduce additional grey levels or colors. For example (assuming 8 bit pixels), a very dim grey level image whose pixel values range from zero through four can be scaled by 64. The result will have high contrast - both dark and bright pixels - but still have only 5 different grey levels and lack continuous tonality.

Contrast to ''Analog Gain''.

Digitize

To convert an analog signal into discrete values. Sometimes used as synonym for Capture, as in ''to digitize an image''.

Dongle

Same as Authorization Key.

DSNU

Dark Signal Non-Uniformity. A camera or sensor's variation of values from pixel to pixel, other than random noise, with no illumination. The pattern of variation is typically unique to each camera or sensor. Some cameras correct DSNU within the camera, other cameras expect DSNU to be corrected outside of the camera. See also ''FPN''.

DSP

Digital Signal Processor. Component which executes computations and gives instructions to manipulate data, specifically designed to operate on signals and images, in contrast to general purpose processors.

EISA Bus

Extended Industry Standard Architecture Bus. Faster successor to the ISA bus. A ISA board will function correctly in an EISA slot.

EMI

Electromagnetic interference.

Equalization Pulses

Two groups of pulses used in some analog video signals which occur before and after serrated vertical sync pulses. Equalization pulses occur at twice the normal horizontal scan rate to insure correct 2:1 interlacing.

Even Field

See ''Interlace''.

Exposure (Period)

The duration of time that a sensor's photosites are sensitive to, and integrating the intensity of, light so as to affect the image intensity. Often a synonym for ''Shutter (Period)'' when used in the context of a camera with digital sensor.

ExpressCard/34

A style of peripheral card used on laptop computers. An ExpressCard/34 host supports both PCIExpress and USB 2.0; a specific ExpressCard/34 typically uses one or the other. See PCI-Express Interface.

Actual throughput on most computers is approximately 190 MByte/sec.

The PIXCI® ECB1-34 is an ExpressCard/34 card, using the PCIExpress x1 interface.

ExpressCard/54

A style of peripheral card used on laptops. An ExpressCard/54 host supports both PCIExpress and USB 2.0; a specific ExpressCard/54 typically uses one or the other. See "PCI-Express Interfaces" .

Actual throughput on most computers is approximately 190 MByte/sec.

An ExpressCard/54 host accepts both ExpressCard/54 and ExpressCard/34 cards.

The PIXCI® EC1, ECB1, and ECB2 are ExpressCard/54 cards, using the PCIExpress x1 interface.

File System

The partitioning and sharing of raw disk space into volumes, directories (folders), and multiple files, by the host operating system. Limits on the number of files and their sizes are imposed by the operating system.

File System	Max # of Files	Max File Size (bytes)

Windows FAT16	512 per folder	2³²-1

Windows FAT16 w.	512 per folder	2³¹-1
DOS, Win 95/98/ME

Windows FAT32	65534 per folder	2³²-1

Windows NTFS	2³²-1 per volume	2⁴⁴ - 64*1024

Under Windows FAT16 and FAT32, the maximum number of files per folder (directory) is reduced when long file names (i.e. larger than 8.3) are used. Under Windows NTFS, using 300,000 or more long file names per folder decreases performance.

Under Linux, there are 10 or more varieties of file systems, each with unique limits.

The maximum number of files is significant when capturing video to multiple files, one per image. The maximum file size is significant when capturing video with multiple images in a single file.

FITS (.FTS)

The Flexible Image Transport System file format. An image file format popular in the scientific - particularly astronomy - communities.

Flat Field Correction (FFC)

Correction of an image for the effects of a sensor or camera's photo response non-uniformity and/or fixed pattern noise. See ''FPN'', ''PRNU'', and ''DSNU''. Also known as Non-Uniform Correction (NUC), or Per-Pixel Normalization.

Free-Run (Video) Mode

A camera mode in which the camera is continuously and autonomously exposing photosites and outputting the corresponding pixel values. The exposing and outputting of pixel values continues regardless of whether a frame grabber is connected, or whether the connected frame grabber is in capture mode. Contrast to ''Controlled (Video) Mode''.

Different camera manufacturers use various synonyms, such as ''Continuous (Video) Mode'', ''Internal Sync (Video) Mode'', ''Auto (Video) Mode'', or ''Live (Video) Mode''.

FPN

Fixed Pattern Noise. Used to describe the effects due to ''DSNU'', or used to describe the effects due to both DSNU and ''PRNU''.

Frame

For frame versus field: see ''Interlace''.

Frame Buffer

An ''Image Buffer'' dedicated to receive video fields or frames from a camera at video rate, or from which video fields or frames are sent to a display device at display rate. An Image Buffer physically attached to the video capture or display hardware. Or, an Image Buffer in computer memory for video capture or display hardware supporting DMA; typically dedicated for purpose and pre-reserved so as to avoid allocation or configuration overhead as each video field or frame arrives from the camera or as each video field or frame is to be sent to the display device.

Frame Buffer Memory

A memory for one or more Frame Buffers. Often reconfigurable - enlarging the memory or reducing the image size allows fitting more Frame Buffers and thus more video frames (images) can be captured without incurring the overhead of copying the image data elsewhere.

Frame Valid

A Camera Link signal indicating which scan lines correspond to valid pixel values, and which is the first and last scan line of each image. Other cameras with digital output may also have a ''Frame Valid'' signal, or may have a ''Vertical Blanking'', ''Vertical Sync'', ''V-Sync'', or similar signal for the same (possibly logically inverted) purpose.

Front Porch

The portion of an analog video signal that follows the start of the horizontal blank and precedes the horizontal sync pulse.

Gain (Control)

See as ''Contrast (Control)''.

Gamut

See ''Color Gamut''.

Genlock

To recover and use the original horizontal and vertical timing control signals from an analog video signal.

Genlock (Video) Mode

A camera mode in which the camera is continuously exposing photosites and outputting the corresponding pixel values, with the cycles synchronized to an external signal or video waveform.

Typically, a camera in genlock video mode can only operate at, or near, a specific frame rate; a slower external signal or video waveform ''genlock input'' will either be ignored or corrupt the video output. In contrast, a camera in ''Controlled (Video) Mode'' can operate at various frame rates, from zero up to the camera's designed maximum rate.

Global Reset, Rolling Shutter

Or, ''Rolling Shutter, Global Reset''. A mechanism within some CCD or CMOS sensors in which all photosites start exposing at the same time, but stop exposing at different times. Intended for use with a mechanical shutter or a strobe light to freeze motion. When used without a mechanical shutter and with ''normal'' lighting, the image will darker on one side (typically the top), and brighter on the opposite side (typically the bottom).

Global Shutter

A mechanism within some CCD or CMOS sensors in which all photosites are exposed at the same time. Use of the term ''Global Shutter'' with an ''Interlaced'' camera is ambiguous; all photosites of both fields may be exposed at the same time, or only the photosites of each field may be exposed at the same time.

Different camera manufacturers use various synonyms, such as ''Free-Run Shutter'' (but is not to be confused with ''Free-Run (Video) Mode'').

Gray

Alternate spelling for ''Grey''.

Grey

Alternate spelling for ''Gray''.

Grey Level Image

An image in which each pixel has component value, interpreted as luminance and rendered as black, white, and, optionally, shades of grey. See also ''Monochrome''.

Halftoning

Conversion of a grey level image so as to be representable by (typically) a printer that only prints black (over white), or white (over black). Conversion of a multi-toned color image so as to be representable by (typically) a printer that only prints three, four, or perhaps eight colors (over white).

HDD

Hard Disk Drive.

HDMI Display

A display/monitor using the High-Definition Multimedia Interface to connect to a display controller.

Horizontal Blanking

The portion of the analog video signal when brightness is suppressed at the end of a scan line during which the electron beam retraces from right to left on a CRT-based video monitor.

By analogy, the term may be used with digital video signals as a synonym for the complement of ''Line Valid''.

Horizontal Sync

A pulse contained within horizontal blanking of an analog video signal which synchronizes hardware with the start/end of each line of each frame.

By analogy, the term may be used with digital video signals as a synonym for the complement of ''Line Valid''.

HSB Color

Color space composed of Hue (e.g. red, yellow, orangish-red, etc.), Saturation (degree of dilution with white), and Brightness (level of intensity). The HSB color space is modeled upon human perception of color; in contrast to, for example, ''RGB Color'', which is derived from technical methods used to encode and reproduce color.

Image

A rectangular grid of pixels.

Image Buffer

RAM or other memory used to hold an image or images.

Image Frame Buffer

See ''Frame Buffer''.

Image Sequence

A linear group of images, usually time indexed.

Interlace

Use of (typically) two fields, one termed ''odd'' and the other ''even'', to scan a video frame, each field representing alternate scan lines from the imaging sensor. An interlaced system decreases perceived flicker of live video by increasing the field update rate and originated with the earliest broadcast television systems. But captured and thus static images may show horizontal banding or show the subject material as a ''ghost'' due to each field being exposed at different times and the subject having moved between exposures. Contrast to ''Progressive Scan''.

Some cameras are designed to expose all scan lines of the sensor at the same time, eliminating temporal shifts between fields, but output the scan lines in interlace format so as to maintain compatibility with display and capture devices, these are often called ''Progressive Exposure and interlaced Output''.

Interrupt

Technique used to determine when a device requires attention, by having the device alter the processor's execution in a controlled manner. Contrast to ''Polling''.

IR-Cut Filter

An optical filter which blocks light of infrared (IR) wavelengths, passing other wavelengths. Most CCD and CMOS sensors are inherently sensitive to near-infrared, as well as visible, wavelengths. Lack of an IR-cut filter with a monochrome camera shifts the tonal balance of the image but increases sensitivity, and has (roughly) equal arguments for and against its use. Lack of an IR-cut filter with a single chip color camera using a Bayer pattern sensor will cause, unless the illumination contains little or no infrared, ''washed out'' color, as the typical Bayer pattern color filters all pass infrared wavelengths.

Some cameras contain a built-in (perhaps removable) IR-cut filter between the sensor and the lens. Other cameras do not contain an IR-cut filter, allowing a filter, if desired, to be attached to the end of the lens farthest from the sensor.

Most SILICON VIDEO® color cameras contain an optional IR-cut filter between the sensor and the lens - within the back focus adjustment ring. The filter can be removed by replacing one back focus adjustment ring with another.

IR Filter

An optical filter which passes light of infrared (IR) wavelengths, blocking other, including visible, wavelengths. Not to be confused with an ''IR-Cut Filter''.

ISA Bus

Industry Standard Architecture Bus. The original 8 or 16 bit peripheral bus of the IBM PC.

JPEG (.JPG)

The Joint Photographic Experts Group file format. An industry standard file format used to save digital images. A widely used file format as it is not company or product specific. Most often uses - and to many people, it implies - lossy compression, although optional features also support lossless compression.

Line Valid

A Camera Link signal indicating which pixel clocks correspond to a valid pixel value, and which is the first and last pixel of each scan line. Other cameras with digital output may also have a ''Line Valid'' signal, or have a ''Horizontal Blanking'', ''Horizontal Sync'', ''H-Sync'', or similar signal for the same (possibly logically inverted) purpose.

Line Scan

A method of video acquisition which uses a one-dimensional array or line of photo sensitive elements. Color line scan cameras may have three, closely spaced, parallel one-dimensional arrays or lines of photo sensitive elements, one for each RGB color; or may have two, closely spaced, parallel one-dimensional arrays or lines of photo sensitive elements, the two lines covered by a ''Bayer'' mosaic of color filters; or may have a single array or line of photo sensitive elements, with every third pixel covered by a red, green, or blue filter. A two-dimensional image is ''built up'' by moving the sensor relative to the object being imaged.

Lossless Compression

Any image compression method in which the decompressed image is an exact copy of the original image, bit for bit.

Lossy Compression

Any image compression method in which the decompressed image is not an exact copy of the original image, bit for bit. The quality of lossy (de)compression varies from images which, to most observers, appear identical to the original image, to images that are almost identical except for a few artifacts, to images which are obviously and grossly distorted.

LVDS

Low Voltage Differential Signalling. Also known as RS-644, an EIA standard for differential signalling format for binary data. Capable of higher speeds over greater distance as compared to RS-422.

LVTTL

Specifically: Low Voltage TTL. Generally: Single-ended signalling format for binary data using levels of 0.0 and +3.3 volts (nominal). TTL is intended for high speed signalling between integrated circuits on the same or adjacent boards, although may be used at slower speeds over several feet. Also referred to as ''3.3V TTL''.

Mapping

A correspondence between one set of objects to another; often one set of numbers to another. Often used to describe a rule to convert measured units to real world units. For example, fractional inches on a map to miles, or a number of pixels to inches.

Monochrome

In general: An image or other visual representation using a single color, or shades of a single color. Typically, in the context of digital imaging: An image using only black, white, and, optionally, shades of grey.

A ''grey level image'' is monochrome.

An image composed of RGB pixels, each pixel having identical red, green, and blue values, can be referred to as a monochrome image or a ''colorless color'' image. As can an image using any other color space (such as ''HSB Color'' or ''YCrCb Color'') in which each pixel value resolves to black, white, or a shade of grey.

Monochrome Video

A video mode which has one component, usually luminance, producing a monochrome image.

Multiplexor

A device or component which steers one of several input signals to its output as directed by a control input. Also spelled Multiplexer.

PC/AT Bus

The ISA Bus, 16 bit version. Capable of transferring two to four megabytes per second.

PCI Bus

The Peripheral Component Interconnect Bus. A 32 or 64 bit wide bus operating at 33 or 66 MHz capable of transferring 132, 264, or 528 million bytes per second (or approximately 125.88, 251.77, or 503.54 megabytes per second). Actual throughput on most computers is approximately 100 to 110 MByte/sec. for 32 bit 33 MHz PCI, and approximately 480 MByte/sec. for 64 bit 66 MHz PCI.

The PIXCI® A, CL1, CL3SD, D, D24, D32, D2X, D3X, SI, SV2, SV3, SV4, SV5, SV5A, SV5B, and SV5L are 32 bit PCI cards. The PIXCI® CL2 is a 64 bit PCI card.

PCI-X Bus

A 64 bit wide bus operating at 133 MHz. The ''PCI-X Bus'' is not the same as ''PCI-Express Interfaces''.

PCI-Express 1.1 Interface

A four wire serial interface capable of a raw bidirectional data rate of 2.5 GBits per second (x1 link), 10 GBits per second (x4 link), 20 GBits per second (x8 link), or 40 GBits per second (x16 link). Actual throughput varies, depending in part on the Packet Payload size implemented by the motherboard.

Approximate Throughput (Gbits per Second)

Lane Width	Payload size (bytes)
	16	128	256

x1	1.7	1.7	2.0
x4	6.8	7.0	7.8
x8	13.7	14.0	15.7
x16	27.4	28.0	31.4

Also referred to as ''PCI-Express Gen 1'' or ''PCIe Gen 1''.

Actual throughput on most computers is approximately 190 MByte/sec. for PCI-Express 1.1 x1 cards, approximately 777 MByte/sec. for PCI-Express 1.1 x4 cards, and approximately 1600 MByte/sec. for PCI-Express 1.1 x8 cards.

The PCI-Express Interface specification allows operating a card using a lower lane width in a slot supporting a higher lane width, such as using a x1 card in a x4 slot, resulting in x1 bandwidth. However, the higher lane width slot need not support all lower lane bandwidths; for example, typical computers (circa 2008) with x16 slots might operate a x4 card but only provide x1 bandwidth, not the desired x4 bandwidth.

The PIXCI® A110, D3XE, E1, E1DB, EB1, EB1-PoCL, EL1 (Rev. 6 and earlier), EL1DB (Rev. 6 and earlier), ELS2, SI1, SI2, SV7, and SV8 are PCI-Express 1.1 x1 cards. The PIXCI® A310, E4, E4DB, and SI4 are PCI-Express 1.1 x4 cards. The PIXCI® E8, E8CAM, and E8DB are PCI-Express 1.1 x8 cards.

PCI-Express 2.0 Interface

A four wire serial interface capable of a raw bidirectional data rate of 5.0 GBits per second (x1 link), 20 GBits per second (x4 link), 40 GBits per second (x8 link), or 80 GBits per second (x16 link). Actual throughput varies, depending in part on the Packet Payload size implemented by the motherboard.

Also referred to as ''PCI-Express Gen 2'' or ''PCIe Gen 2''.

Actual throughput on most computers is approximately 448 MByte/sec. for PCI-Express 2.0 x1 cards, and approximately 1011 MByte/sec. for PCI-Express 2.0 x4 cards.

The PCI-Express Interface specification allows operating a card using a lower lane width in a slot supporting a higher lane width, such as using a x1 card in a x4 slot, resulting in x1 bandwidth. The specification also allows operating a card designed for PCI-Express 1.x in a slot supporting PCI-Express 2.0, and vice versa, resulting in the lower of the two bandwidths.

The PIXCI® E4G2-2F, E4G2-4B, E4G2-F2B, e104x4-2f, e104x4-4b, e104x4-f2b, EL1 (Rev. 7 and later), and EL1DB (Rev. 7 and later) are PCI-Express 2.0 x4 cards. The PIXCI® EB1G2 and EB1G2-PoCL PCI-Express 2.0 x1 cards. The PIXCI® E4TX2-2F, E4TX2-4B, E4TX2-F2B, miniH2x4F, and mf2280 are PCI-Express 2.0 x4 devices. The PIXCI® miniH2B and miniH2F are PCI-Express 2.0 x1 cards or M.2 E-Key/M-Key PCIe x1 gen2 cards. The PIXCI® miniH2x4F and mf2280 are M.2 M-Key PCIe x4 gen2 cards.

PCX (.PCX)

An image file format specified by Zsoft for saving S/VGA graphics.

Photosite

The light sensitive cells that compose a solid state imaging sensor.

Pixel

Short for picture element. The fundamental unit of digital imaging. The smallest unit of an image with homogeneous intensity and color. The numeric representation of an intensity and color. Sometimes used interchangeably with ''photosite'' to refer to the light sensitive cells that compose a solid state imaging sensor.

Pixel Binning

To combine pixel values, typically by summation, creating a smaller image. Binning by a factor of ×2 horizontally and vertically yields an image with ¼ the number of pixels, with pixel at coordinates (x,y) in the binned image corresponding to the sum of pixels at (x×2+0,y×2+0), (x×2+0,y×2+1), (x×2+1,y×2+0), and (x×2+1,y×2+1) in the original or potential image. Contrast to ''Pixel''Subsampling"''.''

Pixel Clock

An oscillator, timing circuit, or externally provided signal which is used to sample (i.e. partition) a video signal scan line into pixels. For analog signals, the scan line can be sampled more or less often, with a larger or smaller pixel clock frequency, to provide higher or lower resolution; cameras outputting analog video typically do not provide a pixel clock signal along with the analog scan line. For digital signals, the scan line must be sampled at a precise frequency and phase; cameras outputting digital signals typically provide a pixel clock signal to control sampling of the digital scan line.

Separately, a pixel clock is used to control the timing and readout within cameras using digital sensors. For some cameras the pixel clock frequency is adjustable; a higher or lower pixel clock frequency provides faster or slower frame rates with corresponding side effects, such as shorter or longer exposure limits, greater or lesser levels of fixed pattern noise, photo response non-uniformity, and random noise. For cameras with an adjustable pixel clock outputting digital signals, a higher or lower pixel clock frequency also affects the maximum length of the electrical cable connecting the camera and frame grabber.

Pixel Subsampling (Decimation)

To retrieve or utilize fewer pixels than are otherwise available, creating a smaller image. Subsampling by a factor of ×2 horizontally and vertically yields an image with ¼ the number of pixels, with pixel at coordinates (x,y) in the subsampled image corresponding to pixel (x×2,y×2) in the original or potential image. Contrast to ''Pixel Binning''.

Pixie

One component value of a pixel. A monochrome pixel contains one pixie, a color pixel typically contains three or four pixies. For example, an RGB pixel is composed of green, red, and blue pixies.

PoCL (POCL)

Power over Camera Link. An enhancement to the Camera Link specification that allows providing power to the camera (12V 4W maximum in Base mode, 12V 8W maximum in other modes) over the Camera Link cable.

Photo Response Non Uniformity. A camera or sensor's variation in gain from pixel to pixel. The pattern of variation is typically unique to each camera or sensor. Some cameras correct PRNU within the camera, other cameras expect PRNU to be corrected outside of the camera. See also ''FPN''.

Progressive Scan

A camera in which all scan lines of the imaging sensor are exposed at the same time and output in order. Contrast to ''Interlace''.

Pseudo-color

A technique that assigns a color to each grey level, or blocks of grey levels, of a monochrome image, helping visualize patterns of intensities.

RGB Color

Color space composed of three components: red, green, and blue. The ''natural'' color space for video hardware, as most video monitors use red, green, and blue phosphors or filters, and most video cameras use red, green, and blue filters. RGB color, by itself, is not colorimetric calibrated; the perceived intensity of a given RGB value varies on different hardware. Often abbreviated to ''RGB''.

ROI

Region of Interest. An area of an image subject to modification or analysis. See ''AOI''.

Rolling Shutter

A mechanism within some CCD or CMOS sensors in which each line or column of photosites are exposed at different, or overlapping times. Has the same effect as a mechanical slit shutter; an opaque material containing a transparent slit which is moved across the sensor in a direction orthogonal to the length of the slit. A rolling shutter is best used to image stationary, or slowly moving objects; an image of a rapidly moving object - particularly an object moving parallel to the movement of the slit - will be distorted.

Saturated

The combination of lighting, aperture, and camera sensitivity is such that the pixel value is at its maximum and remains at the maximum value after the light intensity is reduced by an amount which would normally cause a drop in pixel value.

Saturation

The degree of vividness, strength, or purity of a color. The degree to which a color has not been weakened by mixture with white.

Scan Line

The (almost) horizontal line scanned by the electron beam in a CRT-based video monitor, and the corresponding line scanned by a vidicon-based (or similar) video camera. For cameras with digital sensors that serialize pixel data, a scan line is a sequence of pixel values, typically from a horizontal row, of sensor's photosites.

However, many digital cameras may serialize the light sensor's photosites in other than left-to-right and top-to-bottom order. For example, a camera might output the left-most pixel of a row followed by the middle pixel of a row, continue with each pair of neighboring pixels within the row, and continue in the same fashion with each row. Or a camera might output a pixel of the top row, a pixel of the bottom row, continue with each pair of neighboring pixels within those rows, and continue with each pair of rows inward toward the middle. The number of possible serialization order permutations is quite large. With such cameras, the term ''Scan Line'' may either refer to pixel values from one line of the sensor, or to a ''line'' of values output by the camera during one ''Line Valid''.

Shutter (Period)

The duration of time that a sensor's photosites are sensitive to, and integrating the intensity of, light so as to affect the image intensity.

Some cameras may have a mechanical shutter or electronic shutter (e.g. LCD) mechanism passing light for a ''Shutter (Period)'', separate from the sensor's integration control. The sensor's integration control (if any) may then be distinguished as ''Exposure (Period)''.
