To enhance accuracy of handwritten-printed character discrimination in a character recognition process, and to reduce a processing time for character recognition and also enhance accuracy of the character recognition. A gradation distribution of an image character is analyzed (S4), the character color of the image character is analyzed (S5), a gradation ratio between a turning point of a character stroke and the character stroke other than the turning point is analyzed (S6), contrast at an edge of the character stroke is analyzed (S7), the vertical size and center position of the image character are analyzed (S8), the character size of the image character and pitch are analyzed (S9), the first to sixth scores that quantify the respective analysis results are aggregated to discriminate whether the image character is handwritten or printed (S10), and the recognition target item is checked to determine whether it includes both handwritten and printed characters (S11). This makes it possible to enhance accuracy of handwritten-printed character discrimination, which leads to reducing a processing time for character recognition and enhancing accuracy of the character recognition. |
