Abstract
The present invention is a template matching processing device capable of evaluating a similarity degree which supports even a case of intensive morphological change between a design image and a photographic image. In the template matching processing device, matching processing between the design image and the photographic image is performed, a partial design image is obtained by clipping a portion having the highest correlation (step 101), and processing for deforming the photographic image in accordance with the clipped design image (steps 102 to 105) is performed, so that correlation between the deformed image obtained and the design image is taken to be set as the similarity degree.
