"DOCUMENT PROCESSING SYSTEM AND EQUIPMENT" ABSTRACT OF THE DISCLOSURE A document processing system including a digital image capture system, character recognition circuitry, document encoding systems, endorsers, audit trail printers and an in-line microfilm record system enable documents to be read, endorsed, encoded, digitally imaged, filmed and sorted in a single continuous pass through the document processor by way of a modular transport system. Video data compression apparatus and method are employed for use in minimizing the amount of data necessary to store and recall a black and white video image. An image initially obtained by vertically scanning a selected document is 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 being 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 utilized to reconstruct the image.
