CHARACTER RECOGNITION PROGRAM, CHARACTER RECOGNITION APPARATUS, AND CHARACTER RECOGNITION METHOD

PROBLEM TO BE SOLVED: To enable a character string to be accurately recognized by a process of a low load. SOLUTION: Character estimating means "1d" estimates each character of the character string based on image information, and outputs one or more candidate characters as a candidate of its estimation result about each character within the character string. Candidate character string producing means "1e" sequentially produces one or more candidate character strings as the candidate of the character string by extracting and combining candidate characters corresponding to each character within the character string outputted by the character estimating means "1d" one by one with an order of larger frequency of appearance, based on weighted information in which the frequency of appearance of characters included in word registration information in which a plurality of words are registered, is made to corresponded to every character. A character string specifying means "1f" verifies the candidate character string with a word within the word registration information by its produced order, and specifies a word corresponding to the character string from its verification result.
