Abstract
An inspection apparatus and method outputs an accurate matching position even if a search image contains a pattern similar to a template. An image search unit includes a relative position comparing unit which compares the relative position of a template in a template selection image with the relative position of a location currently being searched for in a search image and outputs the amount of position mismatch between the relative positions. A matching position determining unit determines a matching position by taking into consideration the amount of position mismatch in addition to search image similarity distribution information.
