CHARACTER STRING SENSING DEVICE, CHARACTER EVALUATING DEVICE, IMAGE PROCESSING DEVICE, CHARACTER STRING SENSING METHOD, CHARACTER EVALUATION METHOD, CONTROL PROGRAM, AND RECORDING MEDIUM

摘要

Reduction of a processing load, and shortening of a processing time, is realized by performing character string sensing processing on an image. A character string sensing device senses a character string including at least one character from an image. The character string sensing device includes a character information storage unit in which an evaluation value, expressing difficulty of false sensing of the character, is stored in each character. The character string sensing device also includes a search sequence determining unit that determines a search sequence of each character based on the evaluation value of each character included in a keyword input to the character string sensing device as the character string to be sensed. The evaluation value is stored in the character information storage unit. A character search unit searches each character included in the keyword according to the determined search sequence.
