Character recognition system employing continuity detection and registration means
Abstract
Abstract A CHARACTER RECOGNITION SYSTEM WHICH DETECTS AND REGISTERS A CHARACTER BASED ON A MEASURE OF THE CONTINUITY OR CONNECTIVITY OF CHARACTER PORTIONS DURING THE SCANNING OF A CHARACTER. EACH CHARACTER IS OPTICALLY SCANNED, CONVERTED INTO ELECTRICAL FORM, AND THEN SERIALLY ENTERED INTO AN ELECTRONIC FLIP-FLOP MATRIX. A PARTICULAR GROUP OF MATRIX FLIP-FLOPS ARE CHOSEN TO SERVE AS A "WINDOW" AND THESE FLIP-FLOPS OPERATE IN CONJUNCTION WITH RESPECTIVE LOGICAL CIRCUITS FOR DETERMINING CHARACTER CONTINUITY FOR EACH PORTION OF A CHARACTER AS IT PROGRESSES THROUGH THE MATRIX. VARYING PRINTING CONTRACTS ARE AUTOMATICALLY HANDLED BY PROVIDING FOR APPROPRIATE MODIFICATION OF THE LOGICAL CIRCUITS WHICH DETERMINE CONTINUITY IN RESPONSE TO THE EXISTING PRINTING CONTRAST.
