Abstract
A character recognition method and apparatus realizes high-speed character recognition by using small capacity memories. A character in an original image is read as an input character pattern in an image input process. An n-th calculator 109 in a similarity calculation unit 6 inputs the input character pattern into an input pattern memory 110 and compares the input character pattern with a standard character pattern (.phi..sub.m : m=0,M) stored in a dictionary memory 101 sequentially, thus calculating similarities between the input character pattern and the respective standard character patterns. If a CPU 1 issues a similarity calculation request instruction while an n-th calculator 109 is operating, another one of the calculators in a standby status is used so that another similarity calculation can be performed while simultaneously avoiding access conflict in the memory 101.
