PURPOSE:To stably extract features even when the deformation of a characteristic is executed by detecting the edge point, branch point and intersection of a fine line character and replacing the branch point to the edge point based on the black point position information of the periphery of the detected branch point. CONSTITUTION:Multi-value character string data 1 are converted to the binary value of a white point and a black point by an optical processing part and the segment to individual characters is executed by a pre-treatment part 11. Character data 3 are inputted to a feature extracting part 17 composed of a fine line part 12 and a 8-near point data preparing part 13, a singular point detecting part 14, a branch point converting part 15 and a segment feature extracting part 16, the feature of the character data 3 is extracted and a feature 8 effective to a decision is outputted to a deciding part 18. The deciding part 18 determines a category to which the character data 3 belongs based on the feature data.
