ABSTRACT:
An improved apparatus and method of recognizing a character is disclosed. The side frame structures of characters or figures are discriminated by left and right margin detectors and corresponding left and right side frame recognition circuits. A final character discrimination circuit synthesized both the results of a conventional character recognition unit and the frame recognition circuits, and permits discrimination between similarly shaped characters.
