Claim 0:
1. A character recognition method, comprising:
determining that an image of character to be identified corresponds to a matching character of a plurality of registered characters according to a plurality of vector distances to be identified between a vector of the image of character to be identified and a plurality of vectors of a plurality of registered character images 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 by a processor;
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 by the processor;
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 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 by the processor; and
not updating the data of the matching character which is stored and not updating the plurality of historical vector distances of the matching character 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 by the processor.
