PROBLEM TO BE SOLVED: To provide a means for separating and creating an image showing each character from an image where printed characters and hand written characters are mixed. SOLUTION: An edge image data creating section 1112 acquires image data showing the image where the printed characters and hand written characters are mixed, and extracts an edge region of the image. A dynamic-threshold binary image data creating section 1113 extracts a region where the lightness of the image changes discontinuously with dynamic-threshold binarizing processing. A hand-written character removed image data creating section 1114 extracts, as an image region showing the printed characters, the overlap part of the regions extracted by the edge image data creating section 1112 and dynamic-threshold binary image data creating section 1113. A hand-written character image data creating section 1115 extracts, as an image region showing the hand written characters, the difference between the regions extracted by the edge image data creating section 1112 and hand-written character removed image data creating section 1114.
