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.
