PURPOSE: To execute the matching with high precision without increasing dictionary capacity by taking an error occurring set the time of the matching of a deformed handwritten character like an inclined character, etc., into consideration.
CONSTITUTION: In a preprocessing part 2, the linearization of the handwritten character inputted from a tablet 1 is executed. In a feature point extracting part 3, feature point extraction processing is executed. In a stroke coding part 4, stroke coding is executed. In a broadly classifying part 5, broad classification using a stroke number is executed. In an intermediately classifying part 6, an inter partial-pattern vector is calculated, and inter partial-pattern vector matching processing is executed. In a partial pattern value matching part 7, a partial pattern Q value is calculated, and in a correction value processing part 12, the partial pattern Q value is corrected by a correction judging part 11 by using the correction value stored in a memory. In a partial pattern stroke code matching part 8, the matching processing of partial pattern stroke code distribution is executed.
