<P>PROBLEM TO BE SOLVED: To quickly detect an object even when a detection target object is projected on an image in various dimensions in an object detection method for detecting a specific type of object from an image expressed with two-dimensionally arrayed pixels, for example, the head of a human being or the face of a human being. Ž<P>SOLUTION: This object detection method includes: an image group generation step S21 for generating an image group configured of an original image and one or more thinned-out images by thinning out pixels configuring an object detection target original image by a prescribed rate, or for step-by-step thinning out the pixels configuring the original image by a prescribed rate; and a step-by-step detection step 24 for detecting a specific type of object from the original image by successively repeating processes ranging from an extraction process for making a filter acting on a relatively narrow region act on a relatively small image to an extraction process for making a filter act on a relatively wide region on a relatively large image.
