When a character image to be recognized is inputted, each stroke is converted into direction data. The partial pattern dictionary is searched by using the attained direction data and divides the character image to be recognized into a single or plurality of partial patterns. The partial pattern composition dictionary is searched by using the partial patterns attained in the above-described way. A dictionary character is thus attained as the result of recognition.
