Abstract
A character recognition system employs a "hashing" technique of imaged pixels wherein a digital image constituting an array of pixels is divided into a series of sub-arrays. The sub-array digital signal patterns themselves correspond directly to addresses in associated system memories. Each memory address indicates a predetermined set of the possible characters. There is an apparatus for combining the list of possible characters so that signals corresponding to only one character are output.
