PROBLEM TO BE SOLVED: To provide a character recognition dictionary creation method and its device for discriminating similar characters with less computational complexity by selecting the small number of features making contribution to identification out of the original features, and a character recognition method and its device thereof, and a storage medium in which the character recognition dictionary creation program and the character recognition program are stored. SOLUTION: By applying a genetic algorithm to the feature selection, and altering generation to the gene having a rate of the recognition beyond a fixed value with a degree of conformance in reduction ratio of the features, the small number of features with high recognition capability can be obtained. Moreover, the feature of the recognition dictionary is acquired by the feature number stored in the detailed recognition dictionary in the detailed recognition, so that the character recognition system with high accuracy and the small dictionary capacity can be obtained.
