A real-time, digital, video processing system offers a flexible means for performing high-speed, on-line, automated product inspection. With the capability to digitize and store a 512 x 512 multi-gray level image in 1/30 second as well as subtract a reference image from a new image in a TV frame time, it is possible to perform high-speed inspection of parts, packages and labels. Such a unit can operate as a stand-alone unit or as a pre-processor for a dedicated or time-shared computer. Design trade-offs and examples of specific applications will be discussed.
