Candidate contour curves for a tracking object in the current frame are determined using a particle filter, based on the existence probability distribution of the tracking object in a frame which is one frame previous to the current frame. To match a candidate curve against a contour image of the current frame, a processing to search for the closest contour to the candidate curves is divided for each knot constituting the candidate contour curve and is executed in parallel by a plurality of processors. Each image data on a search region for each knot to be processed are copied from a contour image stored in an image storage to the respective local memories.
