ABSTRACT:
Even if a margin area, which did not exist in an original image, is present around a document area in a document acquired by printing the original image, an accurate layout comparison between the scanned image of the printed document and the original image can be performed as follows. An original image serving as a comparison target image is input, and block information about a block included in the original image is extracted. It is determined whether the size of the original image is a predetermined size. When the size is not a predetermined size, block information about the block included in the original image mapped to a predetermined size is created and registered. When a comparison source image is input, block information about a block included in the comparison source image is extracted. Subsequently, two pieces of the block information of the comparison source and target images are compared.
