Video Frame Processor is a stand alone unit capable of digitizing, storing, processing and displaying image information from TV camera and having a provision to communicate this data with Personal Computer. Its special feature is 'On-line' subtraction of incoming image data. The video signal can be fed to this unit for digitizing and storing the information. The video signal is digitized on line using Flash A/D converter and stored in static Random Access Memory. The memory is read out in TV format so as to display the stored information on Standard TV Monitor. Internal Synchronizing Signals get automatically stored in the absence of external signals to display the stored image.

An important feature of this instrument is its differencing capability of video rate (10 MHz). Incoming TV frame is subtracted point by point from the stored frame so as to display on line difference image. This high speed difference image is achieved due to the provision of Look Up Tables (LUT). The stored image (or the difference image) can be further processed by using in built image processing functions like Gamma Correction, Contrast Enhancing, Gray Scale Windowing, Contrast Stretching and Video Inversion. This system can be coupled to an IBM PC/XT/AT System by standard serial or parallel communication port for further processing.
