Mux (ERROR FIELD- (nm'a BUFFER FULL F/F) (MEM. saacutsruNzzcsi-m) Mar. 18, 1975 [57 ABSTRACT An optical character recognition system is arranged to process format conditioning documents which designate the locations of data fields on data documents to be read. Those portions of the data documents outside the data fields which are designated by the conditioning document are rendered invisible to the system, thereby permitting the system to process only data which may be located in the midst of other'printed matter.
  • a fine line adjustment capability permits the system to reposition the document as necessaryto locate a data field which is not located precisely as had been indicated by the format conditioning document.
  • the system is thus automatically adaptable to any data format without requiring specialized programming.
  • the system samples successive vertical slices of data characters being optically scanned and reassembles the slices electronically for purposes of recognition.
  • the position of each slice is analyzed in order to predict the position, relative to the photo-sensitive array, of the next slice.
  • This permits reliable system adaptation to a data line which is fully or partially skewed relative to its document page. Failure to recognize one or more data characters during scan of a line results in successive automatic re-scans of that line with automatic increase of detection sensitivity during each rescan to permit characters of relatively light print to be recognized.
