ABSTRACT:
An image processing system and image judgment method able to suitably judge whether or not an image includes an image of a predetermined subject to be captured as the image and a program run in the image processing system are provided. Edges of a captured image are enhanced, and an evaluation value Ev concerning intensities of edges and/or amounts of edges included in the captured image is acquired based on values of pixels included in this edge enhanced image. It is judged whether or not the captured image includes an image of a predetermined subject FG based on this acquired evaluation value Ev. It becomes possible to accurately judge if the captured image includes an image of the predetermined subject FG. Further, it is also possible to judge if the image of that subject FG is suitable for a predetermined purpose (for example a template use image of biometric authentication) in accordance with the evaluation value Ev.
