PROBLEM TO BE SOLVED: To efficiently and accurately discriminate a document in the case of discriminating the document by utilizing characters inside the document. SOLUTION: A template preparation part 1101 prepares a template for which the pixel value of pixels for which each pixel forming a binary image for which a reference character string image to which a minimum value filter applied is binarized and the pixel forming the binary image of an input character string image corresponding to the pixel are both black pixels are the black pixel. A noise cut image extraction part 1102 cuts out the pixel value of a template part from the input character string image and extracts a noise cut image for which noise components are eliminated from the input character string image.
