Multiview video decoding apparatus and multiview video decoding method

Abstract

Even when an error occurs, disturbance of the decoded image can be sufficiently suppressed. A multi-view video decoding device (100) for decoding a video stream including coded first video information of a first viewpoint and coded second video information of a second viewpoint includes a decoder for decoding the video stream. part (120), an error detection part (130) that detects an error from a moving image stream, and an error image repair part (140) that repairs the detected error, and the error image repair part (140) has: a decoding control part (142 ), when an error is detected in the first encoded image information contained in the first moving image information, the decoding unit (120) is controlled so that the second moving image information scheduled to be decoded after the first encoded image information decoding of the included second encoded image information; and a restoration processing unit (143) for repairing detected errors using decoded image information generated by decoding the second encoded image information.

Description

technical field [0001] The present invention relates to a multi-view video decoding device for decoding a video stream in which video information from multiple viewpoints is coded for stereoscopic viewing, and in particular to decoding video information from one viewpoint with reference to video information from another viewpoint A multi-view video decoding device for encoded video streams. Background technique [0002] As one of techniques for compressing and encoding moving image information, an encoding technique based on the MPEG (Moving Picture Experts Group) standard is known. In recent years, MPEG2, MPEG4, MPEG4 AVC, and the like are known as major MPEG standards that have spread. [0003] The main feature of these compression techniques is to encode the difference between a picture to be coded (hereinafter referred to as a picture to be coded) and a picture that has already been coded and reconstructed (hereinafter referred to as a reference picture). Specifically,...

Problems solved by technology

However, if the right-eye image at the same time is decoded after the left-eye image, the right-eye image cannot be used for error correction.

[0022] As described above, in the above-mentioned prior art, it is impossible to select an image more suitable for repairing errors, and it is impossible to sufficiently suppress disturbance of a decoded image.
