摘要

The disclosed multi-view image coding/decoding device first obtains depth information for an object photographed in an area subject to processing. Next, a group of pixels in an already-coded (decoded) area which is adjacent to the area subject to processing and in which the same object as in the area subject to processing has been photographed is determined using the depth information and set as a sample pixel group. Then, a view synthesis image is generated for the pixels included in the sample pixel group and the area subject to processing. Next, correction parameters to correct illumination and color mismatches in the sample pixel group are estimated from the view synthesis image and the decoded image. A predicted image is then generated by correcting the view synthesis image relative to the area subject to processing using the estimated correction parameters.
