Document processing system and equipment.

摘要

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. The encoding of the continuously moving documents is accomplished by a plurality of fixed dies, electronically controlled hammers, and an ink bearing ribbon interposed between the documents and the fixed dies. Scanning and digitizing of the documents is effected by continuously transporting the documents across the focal plane of stationary scanner where the documents are repetitively scanned in a single axis, two scanners being employed to permit scanning and digitization of both sides of a particular document in a single pass through the transport mechanism. The system includes apparatus for visually displaying an image which corresponds to a plurality of stored digital values, the apparatus including an image memory and circuitry enabling the display to be partitioned into discrete portions of variable sizes. Additionally, circuitry is provided which allows image rotation, mirror imaging and discrete video attribute selection within each portion of the display. 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.
