PROBLEM TO BE SOLVED: To recognize a crushed character and a blurred character with a high precision. SOLUTION: A normalizing means 2 which performs normalization processing of a binary character pattern, a blurring means 10 which blurs the character pattern after the normalization processing to generate a multi-level character pattern, an observation point extraction means 11 which scans the multi-level character pattern inward from the outside and takes a point, which crosses a zero crossing point where the density of picture elements is increased in the scanning direction, as an observation point to obtain the observation point for feature extraction, a multi-level direction contribution degree extraction means 12 which extracts the degree of contribution in the multi-level direction representing a local shape of the character from each of observation points obtained by the observation point extraction means 11, a feature generation means 5 which generates a feature quantity to be used for character discrimination from degrees of contribution in the multi-level direction obtained by the multi- level direction contribution degree extraction means 12, and a character discrimination means 6 which uses the feature quantity generated by the feature generation means 5 to discriminate the character are provided for the character recognition device.
