PROBLEM TO BE SOLVED: To provide a character recognition technology adaptive to an imaged image of low contrast, and combining reduction in data processing quantity necessary for character recognition with adaptivity to the variety of a character string. SOLUTION: For the whole part of a character string image constituted by including a plurality of character areas, character segmentation position candidates as the candidates of the boundary of the character areas are determined (A), and the character segmentation position candidates are made to correspond to the boundary of the plurality of character areas and the character candidate areas as the candidates of the plurality of character areas can be determined, and the area arrangement candidates expressed as the combination of the character candidate areas are determined (B), and image recognition is performed for each of the character candidate areas, and the optimal area arrangement candidate is selected from among the area arrangement candidates based on the result of the image recognition (C), and a character string constituted of characters recognized by the image recognition (C) for the character candidate areas corresponding to the optimal area arrangement candidate is output as a recognized result character string.
