Abstract

The present invention reduces the encoding amount required by information encoding for predicted image generation during the predictive encoding of a video. A reference frame list, namely a list of reference frames for reference during the generation of a predicted image, is generated. Movement information used during the encoding of a textured video that corresponds to a processing region is set as texture movement information. Depth-map movement information, which represents a region on a reference frame that corresponds to the processing region, is set. At such time, if the index value that specifies the reference frame included in the texture movement information is smaller than the size from the reference frame list, the texture movement information is set as the depth-map movement information. A predicted image that corresponds to the processing region is generated on the basis of the depth-map movement information that has been set.

Description

technical field [0001] The present invention relates to a moving picture encoding method, a moving picture decoding method, a moving picture encoding device, a moving picture decoding device, a moving picture encoding program, a moving picture decoding program, and a recording medium. [0002] This application claims priority based on Japanese Patent Application No. 2012-154066 for which it applied to Japan on July 9, 2012, The content is used here. Background technique [0003] Conventionally, there is known a free-viewpoint image in which a user can freely designate the position and direction of a camera in a photography space (hereinafter, referred to as a viewpoint). Since the user specifies an arbitrary viewpoint in a free viewpoint image, it is impossible to save the image for all its possibilities. Therefore, a free-viewpoint image is composed of information groups necessary to generate an image of a specified viewpoint. A free-viewpoint image can be expressed using...

AI Technical Summary

Problems solved by technology

However, in this method, the mark needs to be encoded for each region, so there is a problem that the amount of code increases accordingly

In addition, in order to share motion information, the corresponding entries in the reference picture list must be the same time and the same type of reference frame, there are also problems that there are few regions where motion information can be shared, and the amount of code required to encode motion information increases.
