Abstract
A character recognition apparatus, for use with an input character pattern and a dictionary of stored character patterns that are blocked into categories, all the patterns having a quantifiable format, in which a judging circuit performs a comparison of the patterns based on the quantifiable format and determines whether the quantified difference exceeds a threshold value in order to determine whether the input and stored character patterns match. The threshold is reduced, as lower mismatch quantities are found for a given character, and when a comparison exceeds the threshold, thereby indicating a mismatch, a new stored character is examined. As among all stored characters that have passed the threshold test, the one with the lowest mismatch quantity is selected as the recognized character.
