ABSTRACT:
A hand-written character recognition apparatus with a personal dictionary preparation function has a character recognition unit for comparing an input hand-written character data with a registered standard dictionary to recognize a most similar character pattern, and a display unit for selecting and displaying a display font corresponding to the recognized character pattern, so that a personal peculiar character or simplified character inputted can be recognized. When a personal dictionary is to be registered, the character to be registered is inputted by hand-writing, the character recognition unit compares the input hand-written character data with the standard dictionary to recognize a similar character pattern, and the recognized character code of the standard dictionary is selected as the character code to be registered. When the personal dictionary is to be prepared, a personal pattern input frame which permits simultaneous input of a plurality of personal hand-written character patterns is provided, and the input personal patterns are allotted to one character code to be registered. When the personal character pattern is to be prepared and registered, similarity between the input personal pattern and the registered dictionary pattern is checked, a stability index indicating a degree of stability of recognition of the personal pattern is calculated based on the similarity, and the stability index is displayed.
