By a program stored in a computer program product for tracking a photographic subject, a computer executes a template matching step of performing template matching upon each frame of an input image with each of a plurality of template images and extracting a plurality of regions whose similarities with each of the template images are the highest from within the input image, a classification step of classifying the extracted regions into regions that are to be used for specifying a photographic subject position within the input image and another region, on the basis of the mutual distances between the extracted regions within the input image, a specification step of specifying the photographic subject position, on the basis of the positions of the regions that have been classified by the classification step as the regions that are to be used for specifying the photographic subject position within the input image, and a photographic subject tracking step of tracking the movement of the photographic subject over the image consisting of a plurality of frames, by tracking the photographic subject position between frames.
