Claim 1:
2. An information processing method comprising steps of:
determining whether or not a character string of candidate characters obtained by executing a first character recognition process for an image matches with a word of a word dictionary;
generating a plurality of character string patterns based on the candidate characters obtained by executing the first character recognition process for the image;
determining whether or not at least one of the generated character string patterns match with at least one of predefined arrangement patterns of character types; and
in a case where it is determined that the character string of the candidate characters does not match with the word of the word dictionary and where it is determined that at least one of the generated character string patterns match with at least one of the predefined arrangement patterns, executing at least one second character recognition process in which character type limitation corresponding to each of the matched at least one of the predefined arrangement patterns is performed.
