Abstract

An image processing apparatus for deleting an undesired image from an image includes a scanning part, an image memory for storing an image of a document being scanned, a delete-image memory for storing predetermined standard geometry parameters with respect to a delete image, the standard geometry parameters defining a predetermined configuration of the delete image, a candidate fetching part for fetching a candidate image from the stored image of the document based on the standard geometry parameters, a candidate rotating part for rotating the candidate image, a discrimination part for detecting whether or not the candidate image is a delete image by comparing a configuration of the rotated candidate image with the predetermined configuration of the delete image, a deletion part for deleting the detected candidate image from the stored image of the document if it is detected that the candidate image is a delete image, and an output part for outputting the stored image in the image memory from which the detected candidate image is deleted.
