Abstract
There is provided a subject tracking apparatus. An obtainment unit obtains first and second shot images, and depth direction distance information in a plurality of regions in each of the first and second shot images. A specifying unit specifies a subject to be tracked in the first and second shot images based on the distance information of the first and second shot images. The specifying unit specifies a region of the subject to be tracked in the second shot image corresponding to a region of the subject to be tracked in the first shot image by comparing histograms of the distance information of the first and second shot images.
