Abstract
A target object detection section detects the region of an image of a target object from a frame image captured as a moving image. A contour search section samples the values of pixels in four diagonal directions in a pixel array, using as a start point a pixel of which the corresponding element targets G (green) for observation in the region. The contour search section then detects coordinate point candidates on a contour line of the target object on the basis of changes in luminance Y of the sampled pixels. The contour search section filters the coordinate point candidates based on luminance changes in the color component of the target object. The contour search section causes the distribution of the coordinate points to approximate the contour line. A position information generation section acquires position information regarding the target object in the real space using the gravity center and size of the target object image obtained from the contour line.
