  • Patent number: 5325195
    Abstract: A video normalizer corrects for irregularities characteristic of video display monitor screens, so as to provide accurate and consistent light levels and color intensities. The normalizer is especially useful for computer controlled editing of video data for the graphics industry. The video normalizer includes a photo sensor for measuring the monitor light output at various locations on the monitor CRT screen, and digital circuitry for providing a correction value for each portion of the monitor screen, with the correction value being applied to the output of a conventional colorgraphics board (video display card) which drives the monitor.

  • Patent number: 4777486
    Abstract: A video image processing system and method for encoding and storing a video image in a bit map array. The system receives a raster scan video signal which it converts into an analog luminosity signal. Then, during each of a preselected repeating sequence of raster scan cycle periods, it encodes a corresponding preselected portion of the information in the analog luminosity signal as a binary value and stores the value in a bit map memory array. As a result, the video image is encoded and stored over a plurality of raster scan cycle periods.
