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.
