A peripheral video-image digitizer card was designed to interface a Texas Instruments Professional Computer to a standard RS-170 video camera, providing real-time digitization and storage of a single video field as a 256 x 256, eight-bit pixel array. This design is intended for the front end of a low-cost PC-based image processing system. The design and construction of the video digitizer system is detailed. Several integrated circuits which make the design of a high-performance digitizing system possible are also described. The digitizing system project was initiated, developed, and successfully completed in the course of one semester of an undergrduate senior laboratory. In addition to providing a number of new digital system hardware and software educational opportunities, the image digitizer establishes the framework upon which future image digitizing and image processing systems are to be built and expanded.
