Abstract: There is provided a depth information generating apparatus. A first generating unit generates first depth information on the basis of a plurality of viewpoint images which are obtained from first shooting and which have mutually-different viewpoints. A second generating unit generates second depth information for a captured image obtained from second shooting by correcting the first depth information so as to reflect a change in depth caused by a difference in a focal distance of the second shooting relative to the first shooting.
