Abstract
An inspection image is assumed to contain many abnormalities when a reference image and an inspection image are misaligned. It has been impossible to determine whether the abnormalities are attributed to the inspection image. An image inspecting apparatus includes: a print alignment portion that aligns a print position of a reference image with a print position of an inspection image; an abnormality detector that detects an abnormality in the inspection image based on a difference between the reference image and the inspection image after print positions are aligned; and a print alignment result evaluator that evaluates a print position alignment result from aligning a print position of the reference image with a print position of the inspection image including an abnormality detected based on dispersion of the difference included in an evaluation region around an edge calculated from a printout image included in the reference image.
