PURPOSE:To improve the accuracy of recognition by executing the recognition processing of the same input character picture unitedly on the basis of plural feature data extracted at different levels. CONSTITUTION:A feature extracting part 4 is controlled by a feature extraction parameter switching part 11 and executes the feature extraction processing of one input character picture on the basis of plural feature extraction parameters P1-P3. The extracted input feature data are stored in an input feature data storing part 5 respectively. A distance calculating part 6 matches a pair of input feature data X1-X3 with reference feature data stored in a reference feature data storage part 7 to calculate the distance and selects every three categories. A weighting processing part 12 sets different weight values to three categories selected by the calculation part 6 in respective data X1-X3. A weight appreciation part 13 arranges the categories in the descending order of weight. A recognition output part 8 selects the category having the maximum weight and outputs the category as a recognized result.
