ABSTRACT:
A character recognizer includes a memory for storing low resolution data of a group of characters to be recognized in an image and a memory for storing high resolution data of the group of characters. Wide range image data for the characters stored in the high resolution memory is selected on the basis of narrower range image data for corresponding characters stored in the low resolution memory. Character recognition is performed according to the selected character image data.
