SILICON VIDEO® 643
High Speed & Low Cost
The SILICON VIDEO® monochrome 643M and color 643C cameras provide 640 by 480 resolution at 211 frames per second (fps). Reducing the number of lines to 2 allows frame rates up to 26,636 fps. Fast frame rates, global shutter, asynchronous reset, and shutter speeds as short as 10 microseconds (1/100,000th of a second) provide sharp images of high-speed motion. Example applications include high-speed inspection, particle tracking, kinematics, collision studies, sports analysis, ballistics, and plant or animal motion analysis. Images can be captured at fast frame rates and can then be played-back at slow display rates to reveal previously undetected details. Individual frames can be extracted from a sequence for further analysis or measurement.
The rugged aluminum camera case is 48.5mm high by 38.4mm wide by 20.8mm deep. Each side of the case has two M3-0.50 tapped holes for attaching the ¼-20 tripod adapter or for mounting. The flexible, category 5e, shielded RJ-45 interface cable provides image data transfer, camera control, and camera power while allowing camera positioning in tight spaces. Multiple cabling options are available, see the SILICON® VIDEO Cable page for more details.
This progressive scan camera connects to the PCI Express bus thru the PIXCI® SI1 (one camera), PIXCI® SI2 (two camera), or PIXCI® SI4 (four camera) imaging board. In addition to providing power, camera control, and data transfer, the PIXCI® SI boards have a trigger input and a strobe output to synchronize external equipment.
Also available is the SV643 camera with an EPIX® imaging computer system that can be configured to capture for a specified frame rate and time period. The SILICON VIDEO® 643 camera is available from EPIX, Inc., or from an authorized EPIX® Distributor.

FEATURES
Sequence Capture with SV643 Camera and XCAP Imaging Program
The SILICON VIDEO® 643 camera is designed to capture thousands of images at fast frame rates.
XCAP-Lite, included with camera purchase, will capture for a maximum of one second at full resolution, 8 bits per pixel, and maximum frame rate. Images must be saved individually.
The XCAP-LTD program captures and saves sequences for more than 2 minutes into 8 GBytes of available memory (computer must have approximately 10 GBytes of installed memory).
The XCAP-STD imaging program offers Video To Disk, which allows sequences to be captured uncompressed directly to a single fast hard drive or solid state drive. With 2 TB of storage space, images can be captured continuously for 8 hours (640 x 480 resolution, 8 bits per pixel, 211 fps). Longer durations are possible.
The XCAP program is optimized for capturing
image sequences. The Capture
Rate & Mode window allows selection of sequence length and interval rate. Linear and Circular sequences
are offered. A Linear
Sequence is a simple capture of a preset number of frames. A Circular
Sequence offers continuous capture until an event stop. The Capture
Event window offers different conditions that can start, modulate, or stop sequence capture. Events
include (among others) Date & Time,
RS-232 Signal, or a Mouse Click.
Images can be overlaid with frame number and time stamp. XCAP offers 16 different time stamp formats (below).
The Display Rate window provides automatic playback at rates easily selected by the user. A sequence can be displayed once, or can be displayed continuously. Display can progress from beginning to end or in reverse. A subset of frames, extracted from the complete sequence, can be displayed or saved.
XCAP compliments the SV643 camera with sequence capture, display, processing, analyzing, and saving operations. Select which version is best for your application by reviewing the description at the XCAP product page.
