SILICON VIDEO 642

The SILICON VIDEO® 642M camera system provides 640 by 480 resolution at 204 frames per second (fps). Reducing the number of lines to 4 allows frame rates up to 19,600 fps. Fast frame rates, global shutter, asynchronous reset, and shutter speeds as short as 20 microseconds (1/50,000th of a second) provide sharp images of high speed motion. Example applications include high-speed inspection, particle tracking, kinematics, collision studies, sports analysis, ballistic analysis, and biological image analysis.

This 10-bit progressive scan monochrome camera system includes camera head, PCI interface board, 7 foot interface cable, and control software. The system provides image transfer to computer memory at rates exceeding 100 megabytes per second.

The rugged aluminum camera case is 3.3 cm high by 3.3 cm wide by 4.5 cm deep, which includes the RJ45 connector. Each side of the case has two M2-0.4 screw holes for the ¼-20 tripod mount.

The category 5e, shielded RJ-45 interface cable is flexible and only 6 mm in diameter. It provides data transfer, camera control, and camera power while allowing easy camera positioning in tight spaces.

The PIXCI® SI imaging board provides a real-time interface between camera head and PCI bus. In addition to providing power, camera control, and data transfer, the board has a trigger input to control data capture, and a strobe output to synchronize external equipment.

The XCAP-Lite camera control and capture program is included with the SV642 camera system. XCAP-Lite captures up to 218 frames with 640 by 480 8-bit resolution. The XCAP-Std program, provides Video To Disk capture at 640 x 480 resolution, 8 bits per pixel, 204 fps, to the limit of the computer’s RAID array (more than 8 hours is possible). User-selectable playback rates [slow motion] reveal hidden detail.

Optionally purchase the SV642 camera with an EPIX® imaging computer system which can be optimized to capture for a specified frame rate and time period.

Sequence Capture with SV642 Camera and XCAP Imaging Program
The SILICON VIDEO® 642 camera is designed to capture thousands of images at fast frame rates.

The SILICON VIDEO® 642 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 to the limit of the available computer memory. Capture for up to one minute with 4 GB of computer memory.

The XCAP-STD imaging program offers Video To Disk, which allows sequences of images to be captured directly to as few as two hard disks configured as RAID 0. Using four 500 GB hard drives, 7200 rpm, images can be captured continuously for 8 hours (640 x 480 resolution, 8 bits per pixel, 204 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 overlayed with frame number and time stamp.

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 SV642 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.

FRAME RATE EXAMPLES (8-Bit mode)

Notes: Reduced horizontal resolution (less than 640 pixels / line) increases the number of available frame buffers but does not increase frame rate. Pixel clock frequencies above 66 MHz may reduce image quality.
