Abstract
(EN)
A multi-viewpoint image encoding device (1) is provided with: a standard viewpoint image encoding unit (4); depth image encoding unit (5); a parallax information generating unit (2) that generates information on the parallax between standard viewpoints and non-standard viewpoints on the basis of depth images restored by the depth image encoding device (5), and image capture condition information; and a non-standard viewpoint image encoding unit (3) that receives and encodes non-standard viewpoint images on the basis of the standard viewpoint images restored by the standard viewpoint image encoding unit (4), and the parallax information generated by the parallax information generating unit (2).
