ABSTRACT:
In the present invention, a specific region in which the edge of the document is specified as the exterior edge is discriminated for the presence of an image, and images separated from the exterior edge of an area positioned on the interior side of the interior edge of said specific region are discriminated as unnecessary images and erased. Also, in the present invention, images including parts adjacent to the edge of a document within a read image are examined and intersections of the edges and outlines of the images are discriminated, and unnecessary images of user fingers are discriminated from necessary images such as headers and the like and erased. Also, in the present invention, images directly adjacent to the exterior side and interior side of the document edges can be discriminated as unnecessary images by focusing on the hands of a user holding the book document and covering a part of the document at the exterior side, and recognizing similarities in pixel density.
