摘要

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.

1. A moving picture encoding method for dividing each frame constituting a depth map moving picture into processing regions each having a predetermined size and performing predictive encoding for each of the processing regions while using motion information when a texture moving picture corresponding to the depth map moving picture is encoded, the method comprising:
a depth map reference frame list generating step of generating a depth map reference frame list which is a list of reference frames to be referred to when a predicted picture is generated; a texture motion information setting step of setting motion information used when the texture moving picture corresponding to a processing region is encoded as texture motion information; a depth map motion information setting step of setting depth map motion information representing a region on a reference frame corresponding to the processing region, the depth map motion information setting step setting the texture motion information as the depth map motion information if an index value which is included in the texture motion information and which designates a reference frame on a texture reference frame list which is a list of reference frames used when the texture moving picture is encoded is less than the size of the depth map reference frame list; and a predicted picture generating step of generating the predicted picture for the processing region in accordance with the set depth map motion information.
