Abstract: A document processing system comprising an image capture subsystem for capturing selected image metrics and at least one image rendition from a plurality of documents and for determining if at least one of the selected image metrics for any of the at least one image rendition does not successfully compare against preselected image quality metric threshold values. An image quality flag is generated for any of the at least one image rendition if it does not successfully compare, and a record entry for each imaged document having at least one flagged image rendition is created in an image quality flag file. An image index file for individually accessing the image renditions is modified to include a reference to the corresponding image quality flag file record entry The document processing system may optionally compare selected document metrics against preselected document metrics in a similar manner.

Abstract: An image quality assurance method for identifying image defects in a plurality of previously-imaged documents, where each previously-imaged document includes at least one image rendition stored in at least one image rendition file according to type of image rendition. The image renditions are analyzed to provide selected image metrics, the latter of which are compared against preselected image quality metric threshold values. An image quality flag is generated for any image rendition if at least one of the selected image metrics for that image rendition does not successfully compare against the preselected image quality metric threshold values. A record entry is created in an image quality flag file for those documents having at least one flagged image rendition, the record entry including information about the selected image metrics of the at least one flagged image rendition for that imaged document.

Image defects in a plurality of imaged documents can be identified by examining the record entries in the image quality flag file.

Abstract: A method for identifying image data bits, especially where the image data is to be reliably co-identified with collateral document has been disclosed. Such “identification-bits” should be carried with the image data through various stages of processing, so the image's identity can be maintained at each processing station, and can be transferred to a downstream processing station. A salient object hereof is to identify image data; especially with “sync bits”.

Abstract: An electronic document-imaging arrangement wherein imaging means generates imaging-bits representing a given document and transfers these bits on a "per-document basis" to various successive electronic processing stages and, finally, to a data base storage unit (DBS); this arrangement also including a tag stage for creating tag bits unique for each such imaged document; these tag bits to be transferred with the imaging bits for each document to each such processing stage that handles the imaging bits, on a per document basis, and finally to DBS interface means for final matching and removal of the tag bits.

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; andboth said compressions being performed on a single, two pass stage of a Histogram/Compressor printed circuit board.

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.

Abstract: A pipelined image processor is disclosed which contains a diagnostic apparatus which, under normal processing conditions, is coupled to and is in communication with resequencer, image processor, and transposer/compressor assemblies contained within the pipelined image processor. The diagnostic apparatus of this invention causes a diagnostic test pattern to be sent to the re-sequencer and image processor entities of the pipelined image processor and monitors the response thereof. This response is then used to detect faults which have occurred in these entities.
