Claim:
1. An image processor for detecting a position of a given target of a subject shot with a camera, the image processor comprising: a depth image acquisition portion adapted to acquire a depth image representing, on an image plane, a distance of the subject from the camera in a depth direction as a pixel value; and a matching portion adapted to adjust a size of a template image prepared for the target in accordance with a position of the template image and the distance of the subject represented by the depth image in the depth direction, evaluate the matching of the picture of the subject based on the pixel value within an area corresponding to the template image on the depth image or the image shot with the camera, identify the picture of the subject, the target, based on the matching evaluation result, generate position information thereof, and output that information, wherein: the depth image acquisition portion acquires depth images of a plurality of resolutions, and the matching portion evaluates the matching of the subjects in each of the depth images of one of the resolutions by restricting the evaluation to the subjects existing within a range of the distance in the depth direction associated with one of the resolutions.
