Method of registering a character pattern into a user dictionary and a character recognition apparatus having the user dictionary
First Claim
1. A character recognition apparatus that inputs a character pattern and recognizes the character pattern, said character recognition apparatus comprising:
- input means for inputting a character pattern to be registered into a dictionary;
warning issuing means for recognizing the input character pattern, for automatically judging whether or not the input character pattern is a suitable pattern to be registered into the dictionary based on a recognition result of the input character pattern and reliability of the recognition result, and for automatically issuing a warning corresponding to the input character pattern in a case that the input character pattern is not a suitable pattern to be registered into the dictionary;
indicating means for indicating whether or not the input character pattern corresponding to the warning should be registered in the dictionary;
registration means for registering the input character pattern together with information indicating that the input character pattern has been registered in spite of the warning in a case that said indicating means indicates that the input character pattern should be registered in the dictionary.

Abstract
In the present invention, an input handwritten character pattern is subjected to character recognition processing, and a recognition reliability of the character as a standard characteristic feature pattern is determined from the recognition result. If the recognition reliability is low, a warning is issued. In response to the warning, a user or operator can decide whether the character pattern should be registered in the user dictionary (106). If it is decided that the character pattern should be registered in the user dictionary, the character pattern is stored in the user dictionary with the information representing that the character pattern has low recognition reliability. When character patterns registered in the user dictionary are displayed on a screen, these characters are displayed in such a manner that it is possible to distinguish characters having low recognition reliability from characters having high recognition reliability. There is also provided a user name index file (5309) for storing information regarding characteristic features of a handwritten character pattern peculiar to a specific user. Furthermore, there is also provided a password input-and-decision part (5103) for making a decision of whether or not allow to access to the user dictionary based on the information of the handwritten character pattern input by a specific user.
