摘要

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