IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING PROGRAM

PROBLEM TO BE SOLVED: To provide an image processing apparatus that extracts a difference between images in a plurality of figures by taking positional displacement of images into consideration, targeting only the images inside the frame of the figures.SOLUTION: Image acceptance means of an image processing apparatus accepts images of a plurality of figures; division means divides images accepted by the image acceptance means into frame images and images within the frame; mapping means maps the images within the frame of the figures divided by the separation means; processing means performs extraction processing on an image of a difference at least between images within the frame mapped by the mapping means; and output means outputs the image of the difference subjected to the extraction processing by the processing means.
