Title: INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD
Abstract:
An object detecting unit detects a region of an image of an object from a frame image obtained by capturing a moving image (S10). A contour search unit samples pixel values in four diagonal directions in a pixel array, using as a start point a pixel, within the region of the image, of which an observed object of a corresponding element is G (green) (S12, S14). A coordinate point candidate on the contour line of the object is then detected on the basis of a variation in a brightness Y of a sampled pixel, and having performed filtering on the basis of a variation in the brightness of a color component of the object, the contour line is approximated from the distribution thereof (S16, S18, S20). A position information generating unit acquires position information of the object in real space using the center of gravity and size of the image of the object obtained from the contour line (S22, S24).
