PCVision:
    Monochrome Frame Grabber for Analog Area Scan and
    Progressive Scan Cameras

Key features

 

This half-slot PCI-bus card moves images to the host PC in less
than 4 ms, providing an additional 29 ms of free processing time
Onboard 2MB VRAM frame buffer and DMA bus master contribute
to industry's fastest sustained image transfer speed over the
PCI-bus, eliminating unnecessary processor overhead

"real world" applications and demanding cycle times
DMA of Areas of Interest (AOI's) minimize transfer times
Video window allows for the selection of number of pixels per
line and number of lines per image
Onboard 16-bit digital I/O facilitates communication results to
outside world
Non Destructive Overlay support
Up to 4 monochrome RS-170 or CCIR cameras
Supports nonstandard area scan cameras up to 2K x 1K,
interlaced or progressive scan

 

Overview

 

PCVision is a half-slot PCI-bus image capture card designed specifically for price sensitive OEMs
developing machine vision applications. Capable of handling inputs from a large variety of industrial
inspection, identification, and gauging applications, the PCVision board can interface with standard
interlaced (RS-170, CCIR) or progressive scan cameras.

Unique to PCVision is 2MB of onboard VRAM memory for buffering image data between the camera
and host PC system. This feature, not found in other low-cost machine vision boards, allows image
transfers over the PCI-bus that are 10 times faster than competitors, permitting simultaneous data
acquisition and processing. Onboard memory also assures that image information will not be lost
during transfer to system memory.

PCVision supports external trigger, strobes, and frame reset capabilities. A 16-bit digital I/O interface
for communicating results to control devices is built into the board itself.
