Abstract: High coding efficiency is achieved when disparity-compensated prediction is performed on an encoding (decoding) target picture using depth information representing a three-dimensional position of an object in a reference picture. A correspondence point on the reference picture is set for each pixel of the encoding target picture. Object depth information which is depth information for a pixel at an integer pixel position on the encoding target picture indicated by the correspondence point is set. A tap length for pixel interpolation is determined using reference picture depth information for a pixel at an integer pixel position or an integer pixel position around a fractional pixel position on the reference picture indicated by the correspondence point and the object depth information. A pixel value at the integer pixel position or the fractional pixel position on the reference picture indicated by the correspondence point is generated using an interpolation filter in accordance with the tap length.

Abstract: A bit amount necessary to code information for generating a predicted picture when predictive encoding is performed on a moving picture is reduced. A reference frame list, which is a list of reference frames to be referred to when a predicted picture is generated, is generated. Motion information used when a texture moving picture corresponding to a processing region is encoded is set as texture motion information. Depth map motion information representing a region on a reference frame corresponding to the processing region is set. At this time, the texture motion information is set as the depth map motion information if an index value designating a reference frame included in the texture motion information is less than the size of the reference frame list. The predicted picture for the processing region is generated in accordance with the set depth map motion information.
