Abstract:
1. A depth estimation apparatus for generating, for each of plural scenes, a depth map using a set of multi-focus images which correspond to the scene and have different focuses, the depth map showing a depth for each of first regions included in the scene, the depth estimation apparatus comprising: a processor; and a non-transitory computer-readable medium having stored thereon a program that, when executed by said processor, causes said depth estimation apparatus to function as: a cost value computing unit configured to compute, for each of the scenes, a cost value for each of the first regions using the set of multi-focus images corresponding to the scene, the cost value of each first region indicating a difference between a blur amount corresponding to the respective first region and a standard blur amount determined for each of distances in a depth direction; a depth map generation unit configured to generate an initial depth map that is a depth map of the scene by estimating a depth of at least one of the first regions based on the cost value of the respective at least one first region; a motion estimation unit configured to estimate the motion of the at least one first region based on the cost value of the respective first region computed by said cost value computing unit; and a depth compensation unit configured to compensate, based on the estimated motion of the at least one first region, depth information included in the initial depth map of a scene to be processed, with depth information included in another scene.
