1. A depth information generating apparatus comprising at least one processor and/or at least one circuit which functions as:
a first generating unit configured to generate first depth information on the basis of a plurality of viewpoint images which are obtained from a first shooting and which have mutually-different viewpoints, wherein the first shooting is live view shooting; and
a second generating unit configured to generate second depth information for a captured image obtained from second shooting, which is a still image shooting at different timing than the first shooting, by correcting depth indicated by the first depth information so as to reflect a change amount in depth caused by a difference in a focal distance of the second shooting relative to the first shooting, and
wherein the change amount in depth is based on a change in zoom position occurring between the first shooting and the second shooting.
