Claim 11:
12. A non-transitory computer readable medium, configured to store a computer software and to perform a character recognition method, the character recognition method comprising:
according to a plurality of vector distances to be identified between a vector of an image of character to be identified and a plurality of vectors of a plurality of registered character images of a plurality of registered characters, determining that the image of character to be identified corresponds to a matching character of the plurality of registered characters, and storing a matching vector distance between the vector of the image of character to be identified and a vector of the matching character;
calculating an average value of a plurality of historical vector distances of a plurality of historical character images of the matching character, and multiplying the average value by a parameter to generate a vector distance threshold;
when it is determined that the image of character to be identified corresponds to the matching character and the matching vector distance is less than the vector distance threshold, updating a data of the matching character which is stored according to the image of character to be identified, and updating the plurality of historical vector distances by storing the matching vector distance as one of the plurality of historical vector distances of the matching character; and
when it is determined that the image of character to be identified corresponds to the matching character and the matching vector distance is not less than the vector distance threshold, not updating the data of the matching character which is stored, and not updating the plurality of historical vector distances of the matching character.
