摘要:
In disparity-compensated prediction, the precision of prediction vectors is improved even if a prediction method different from disparity-compensated prediction is utilized for blocks around a block to be coded. An image coding apparatus (100) codes a plurality of viewpoint images captured from different viewpoints. The image coding apparatus (100) includes: an imaging-condition information coder (101) that codes information indicating a positional relationship between a subject and cameras which are set for capturing the plurality of viewpoint images; a disparity information generator (104) that generates disparity information on the basis of the information and at least one of depth images corresponding to the plurality of viewpoint images; and an image coder (106) that generates, concerning a viewpoint image to be coded, a prediction vector for a viewpoint image different from the viewpoint image to be coded, on the basis of the disparity information, and that codes the viewpoint image to be coded by using the prediction vector in accordance with an inter-view prediction coding method.
