An apparatus and method for recognizing a presented character are provided. The apparatus includes a scanner for extracting black and white information from a document in the form of an analog electrical signal. The analog electrical signal is converted into a three bit binary number by a multi-level quantizer to consequently form three weighted data field geometric configurations consisting of rows of binary signals, which binary signals are stored in a storage area in three data field arrays. A selected one of a plurality of progression word detectors detects in a sequential fashion a plurality of binary progression words or progressions by decoding predetermined combinations of the binary words from all the field arrays. The combinations of binary words represent overlapping neighborhood dependent areas from the data field array. A progression detector circuit detects the predetermined combinations of the detected progressions by means of multiplexers which group predetermined combinations of the detected progressions and binary counters which keep track of the progression times and stores the fact that a progression occurs in the proper progression.

Character recognition system

A method and apparatus for generating display enabling signals representative of unprocessed and processed data streams obtained from a character recognition system for improved identification of minimal quality read signals. The apparatus is operative to generate the display enabling signals concurrently or separately through time as to the unprocessed and processed data streams. The apparatus has the additional capability of being able to operate in a real time state or a delay time state where indefinite display is required.
