PURPOSE:To quicken the processing speed with high recognition accuracy by referencing a matrix dictionary where a standard character mask is described in the same form as a sub-pattern characteristic matrix so as to recognize a character/graphic pattern. CONSTITUTION:The 1st recognizing process offers plural candidate characters to an inputted character/graphic pattern. The 2nd identification process selectionly the character name strings corresponding to a prescribed word in the combined character name strings of candiate characters. The 3rd identifica tion process decides the most suitable candidate word when a prescribed number (ND) of candidate word names exist. In this case, a differential dictionary matrix applies weighting to the distance between the sub-pattern characteristic matrix and the standard characteristic mark. That is, the difference in the both is emphasized. Then the recognition accuracy is improved and the processing speed is quickened.
