PROBLEM TO BE SOLVED: To provide a character recognition device for appropriately setting character candidate areas when performing character recognition processing on a grayscale image.SOLUTION: In respect to an object image being a grayscale image, a character height-direction range being a range in a character height direction perpendicular to a character width direction, in which a character string exists, is detected, and character width-direction ranges being ranges in a character width direction, in which individual characters of the character string exist, are detected also. Further, a character center candidate area is determined for each character of the character string, as an area including a center of the character height-direction range in the character height direction and including a center of the character width-direction range in the character width direction, and a plurality of rectangular character candidate areas each of which has an intersection between diagonal lines at each point in the character center candidate area are set. Character recognition processing is performed on respective parts of the plurality of character candidate areas of the object image to obtain, for each character of the character string, respective character recognition results for the plurality of character candidate areas, and a character identification result for each character of the character string is settled. |
