A peripheral card has been designed to interface the 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. The digitizer card is bus-compatible with any Intel 8088 microprocessor based microcomputer e.g. TI-PC or IBM-PC. At present, the TI-PC based image processing system allows for a high resolution four-bit display of the digitized image as sixteen grey levels for the monochrome monitor, or sixteen color-mapped levels on the color monitor. The system is being extended to reconstruct the RS-170 standard monochrome monitor for eight-bit grey level resolution. Further system extensions include eight-bit digitization, storage, and display of true color video by front end interface of the system to a high resolution TI-CCD color camera. The use of lower level languages has allowed for the implementation of software features such as image display and image enhancement algorithms. FFT spatial frequency filtering and small kernel convolution are available for 128 x 128 and 256 x 256 image array sizes, respectively. In addition to providing a number of digital system hardware and software educational opportunities, the applicability of this system will be invaluable as a cost-effective, compact, yet high performance and quantitative image analyzing system.
