Patent ID: 8254689

Claim:
A character recognition processing method, comprising: extracting, by using a computer, a feature vector for an input character from a reading result of said input character; calculating, by using the computer, distances between said feature vector for said input character and vectors including average vectors stored in a system dictionary storing, for each character, said average vector of said feature vectors and distribution information, and feature vectors stored in a user dictionary storing, for each character, said feature vector; extracting, by using the computer, a top predetermined number of character codes in an ascending order of the calculated distances; obtaining, by using the computer, second distribution information for said character codes, which are extracted from said user dictionary and included in said top predetermined number of character codes; calculating, by using the computer, for each of said top predetermined number of character codes, a second distance with said feature vector for said input character, by using, for said character codes, which are extracted from said user dictionary and included in said top predetermined number of character codes, said second distribution information, and by using, for said character codes, which are extracted from said system dictionary and included in said top predetermined number of character codes, the corresponding distribution information in said system dictionary; and identifying, by using the computer, a character code whose second distance is shortest.
