Low- Profile Video Capture for the PCI Bus

The PIXCI® SV5L digitizes analog video and transfers the digitized video through the PCI bus at full video rate. Video sources that use standard formats (NTSC, RS-170, PAL, CCIR, and S-Video) are supported. As a PCI bus master, the PIXCI® SV5L board transfers image data without using the host computer’s processor. Images may be transferred, at full or reduced frame rates, to computer memory for processing and/or analysis by the host computer’s processor(s), to the S/VGA system for display, or to other targets on the PCI bus such as disk controllers (real time video to disk).

The PIXCI® SV5L and XCAP software can capture video sequences to the computer’s hard drive. Live images may be displayed on the computer’s monitor during image capture. Up to eight PIXCI® SV5L boards in one computer can capture simultaneously from multiple video sources.

ACQUISITION — The PIXCI® SV5L provides 3-input video multiplexer signal selection from two mini-BNC and one S-Video input. Programmable gain, hue, brightness, saturation, and contrast adjustments can condition the video signal.

A unique digital genlock circuit ensures precise synchronization of every image. The PIXCI® SV5L imaging board genlock subsystem accepts video timing from a VCR.

SCALING AND CROPPING — The captured image can be cropped in single pixel increments, and then scaled down to as few as 4 pixels by 1 line. Horizontal and vertical scaling is performed in real-time by interpolation, providing a high quality representation of the original image.

OPTIMIZED IMAGING SYSTEMS – With data transfer directly into the host’s memory at video rates, the imaging potential of the PIXCI® SV5L is limited only by the host computer and peripherals. A high quality computer, graphics card, camera, lighting, and lens are recommended for best results. EPIX, Inc. can supply high quality imaging components to complement the PIXCI® SV5L, as well as complete, customized systems for machine vision, motion analysis, image storage and transmission, and other imaging or video applications. Example applications include automated inspection, motion analysis, microscopy, medical imaging, robotics, laser beam analysis, object tracking, multimedia, and print quality inspection.


Board & Description Order Code



The PIXCI® SV5 offers 2 BNC and 1 S-Video multiplexed inputs.



The PIXCI® SV5A offers 3 multiplexed BNC inputs. All other features are identical to the PIXCI® SV5.



The PIXCI® SV5B offers 1 BNC input and 1 Loop Thru BNC output. The S-Video and trigger connectors are removed to allow for a low-profile PCI form factor with an optional low-profile bracket. All other features are identical to the PIXCI® SV5.



The PIXCI® SV5L offers 2 Mini BNC and 1 S-Video multiplexed inputs. The trigger connector has been removed to allow for a low-profile PCI form factor. A full-height bracket is optional. All other features are identical to the PIXCI® SV5.



The PIXCI® SV5S offers 2 BNC and 1 S-Video multiplexed inputs. Adds additional circuitry that separates the vertical sync. from the video signal. All other features are identical to the PIXCI® SV5.



XCAP - Menu-driven, interactive program for the PIXCI® imaging boards allowing capture, display, viewing, processing, printing, analysis, measurements, loading, and saving of imagery. Includes a script language for customization and automating tasks. XCAP is available for Windows.

XCLIB - "C" libraries for accessing the PIXCI® imaging boards. Supports DOS, Windows, and most popular "C" compilers.

PXIPL - "C" library of image processing and analysis routines, for use with XCLIB.

MUX — The multiplexer selects the video source, for the Programmable Gain, from either the S-Video input connector or from one of the two (composite video) mini-BNC connectors. The multiplexer may be switched during vertical blanking.

Programmable Gain — Compensates for reduced amplitude in the analog signal input. Gain can be programmed from 0% to more than 200%.

Luminance A/D — Provides analog to digital conversion of NTSC, RS-170, CCIR, PAL, and the luminance (Y) component of S-Video sources.

Chrominance (Color) A/D — Provides analog to digital conversion of the color (C) component of S-Video.

Decoder — Separates the Y/C components. Generates the U/V color difference signals.

Digital Genlock — Automatic synchronization circuitry for precise digitization. Accommodates video sources which have variable timing, such as video tape recorders. Generates the pixel clock for transferring image data to the PCI bus interface.

Scaling, Cropping — Interpolation is used to scale images to as small as 1/14 of their original size.

Temporal Scaling — Image sequences may be captured at full or reduced frame rates.

(Optional) Trigger I/O — One TTL input and one TTL output can be used for synchronization with external events.
