PURPOSE: To improve a character recognition speed by forming plural recognition parts and exclusive dictionary parts corresponding to respective recognition parts and dividing and storing reference patterns in these dictionary parts.
CONSTITUTION: The recognition parts are constituted of plural recognition processors 10W50 and the dictionary parts are formed dividedly and independently in each processor. A character pattern separated in each character by a character separating part is simultaneously inputted to the plural processors 10W50 to execute the recognition processing of the character. Namely, respective processors 10'50 extract the features of the input character pattern, match the extracted features with the contents of respective dictionaries 11W51 and output proposed categories and the similarity of the categories to the input character. A final decision part 60 rearranges the proposed categories in the descending order of similarity and sorts the categories. If the similarity of the 1st proposed category is larger than a threshold value K1 and the similarity of the 1st and 2nd proposed categories is larger than a threshold value K12, the 1st proposed category is outputted as the recognized result.
