Abstract
In a system for processing and imaging documents to develop a stream of digital, video bit sets, each related to a different document is a passing array, this system including an arrangement for simultaneously compressing a number of said bit-sets for different document images and sending the results to output, this arrangement as comprising: a preprocessing stage for distributing each said bit set in a pair, of like parallel bit-compression paths, one, a Master path for half the bits in a set, the other a Slave path for the other half as controlled by The Master, with both input to a common buffer, each compression path being adapted to execute a first compression and then a conditional second compression when certain initial factors are indicated and to provide a real-time-compressed output to this buffer; and both said compressions being performed on a single, two pass stage of a Histogram/Compressor printed circuit board.
