摘要： Based on a representative depth determined from a depth map corresponding to an object in a multi-viewpoint video, a transformation matrix is determined which transforms a position on an encoding target image, which is one frame of the multi-viewpoint video, into a position on a reference viewpoint image from a reference viewpoint which differs from the viewpoint of the encoding target image. A representative position is determined which belongs to an encoding target region obtained by dividing the encoding target image. A corresponding position which corresponds to the representative position and belongs to the reference viewpoint image is determined by using the representative position and the transformation matrix. Based on the corresponding position, synthesized motion information assigned to the encoding target region is generated from motion information for the reference viewpoint image, and a predicted image for the encoding target region is generated by using the synthesized motion information.

摘要： When one frame of multiview videos is encoded, each of encoding target regions obtained by dividing an encoding target image is encoded while motion information for a reference viewpoint image from a reference viewpoint other than a viewpoint of the encoding target image is used to perform prediction between different viewpoints. According to information, which indicates a corresponding region on the reference viewpoint image for the encoding target region, and the motion information for the reference viewpoint image, temporary motion information for the corresponding region is determined. Disparity information assigned to a region from the reference viewpoint, which is indicated by the temporary motion information, with respect to the viewpoint of the encoding target image, and the information which indicates the corresponding region are utilized to perform transformation of the temporary motion information, so as to generate motion information for the encoding target region.

A disparity predicted image and a motion predicted image are generated based on the determined information items. A corrective predicted image is generated based on the inter-viewpoint reference information and the inter-frame reference information. The predicted image is generated from the disparity predicted image, the motion predicted image, and the corrective predicted image.
