PURPOSE:To obtain a dictionary for recognition of hand-written characters which is suitable for a user, by synthesizing deformed patterns of characters and selecting the character pattern resembling hand-written characters of the user from them the registering its feature vectors in the dictionary for recognition of hand-written characters. CONSTITUTION:In the learning mode operation, a dictionary retrieving part 11 retrieves the dictionary similarly to the normal mode. If the recognition result is rejected, the operation is performed as follows; a control part 7 displays an input character pattern and a message to an operator on a display device 6, and the operator discriminates a character in accordance with the displayed input pattern and inputs its character code from a key input device 3. This character code is sent to a recognizing part 4 and is given to a dictionary register part 13 through the dictionary retrieving part 11. If there is one candidate character for the input character pattern and the recognition result is rejected because the distance between its feature vectors exceeds the allowable error range of the candidate character, the dictionary register part 13 combines feature vectors of the input character pattern with the key-inputted character code, etc. and registers additionally the result in a dictionary memory 14.
