Claim One:
1. An image inspection apparatus for determining whether a test image is a copy of an original image, comprising: an image group generation unit that receives the original image to determine one or more types of image transform, and transforms the original image according to the determined types of image transform to generate an original image group; a spatial color difference computing unit that transforms a color space of the generated original image group, and calculates first spatial color differences between the original image and images in the original image group to provide color difference data obtained from the calculated spatial color differences; an image inspection unit that receives the test image and the original image group to calculate second spatial color differences between the test image and the images in the original image group, and compares the second spatial color differences to the color difference data to generate a comparison result; and an inspection result output unit that outputs the comparison result.
