PROBLEM TO BE SOLVED: To track an object in a more simple, quick and stable manner. SOLUTION: A flatness determination part 51 determines whether an input image is a flat image, based on dispersion of pixel values of pixels in respective regions of the input image. When the input image is not flat, a tracking part 52 detects movement between frames of the input image to detect an object to be tracked from the input image. When the input image is flat, the tracking part 53 extracts feature quantities of features from the input image, generates an object map indicating the likeness of the object in respective regions of the input image from the feature quantities and detects the object from the input image by using the object map. Since the object is detected by a different tracking method according to whether the input image is flat, the object can be more stably tracked. This invention is applicable to an imaging apparatus.
