ABSTRACT:
A video data compression system and method for use in minimizing the amount of data necessary to store and recall a black and white video image. An image is obtained by vertically scanning a selected document. The image is then represented by a series of consecutive vertical scans identifying particular sections or cells of the image as black or white. A plurality of consecutive scans are then temporarily stored and analyzed horizontally. Analysis circuitry is utilized to identify certain consecutive black or white sections of the image, repetitions of previous sections of the image or repetitions of certain selectable patterns within the image. The coded output of the analysis circuitry is then stored and may be utilized to reconstruct the image.
