A second obtaining unit obtains a reference image defocus amount map and a search image defocus amount map. An extracting unit extracts a feature from each of the reference image, the search image, the reference image defocus amount map, and the search image defocus amount map. A correlation calculating unit performs correlation calculation regarding a feature of the reference image and the search image and feature of the reference image defocus amount map and the search image defocus amount map. A tracking result calculating unit calculates a tracking result including a position of the tracking target object by using a result of the correlation calculation.
