Abstract
A pipelined image processor generates an image of the information contained on first and second portions of a document. The pipelined image processor includes a first pipe for processing information contained on the first portion of the document, and second pipe for processing information contained on the second portion of the document. The pipes receive the output from two camera assemblies which are used for generating an electrical signal in response to information contained on the document, an image digitizer for generating digitized information from the electrical signal by the means for generating an electrical signal. In addition, both pipes also include a resequencer for generating resequenced information from the digitized information, as well as an image processor for generating processed information from the resequenced information. Finally, the first and second pipes include a transposer/compressor assembly for generating transposed and compressed information from the processed information, and a compressed data buffer for storing the transposed and compressed information.
