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.
