Abstract: When multiview images are encoded, a first viewpoint-synthesized image for an encoding target region is generated by using a reference viewpoint image from a viewpoint other than that of the encoding target image and a reference depth map for the reference viewpoint image. A second viewpoint-synthesized image for reference pixels is generated by using the first viewpoint-synthesized image, where the reference pixels are a set of already-encoded pixels, which are referred to in intra prediction of the encoding target region. An intra predicted image for the encoding target region is generated by using a decoded image for the reference pixels and the second viewpoint-synthesized image.

Abstract: 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.

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.

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.

Abstract: The image encoding apparatus encodes while predicting an image between different views using a reference image encoded for a view different from a processing target image, and a reference depth map for an object of the reference image when a multiview image of plural different views is encoded. A view-synthesized image is generated for the entire encoding target image using the reference image and the reference depth map.

Information is encoded to indicate the prediction unit. An encoding section performs predictive encoding on the encoding target image for every encoding target block, while selecting a predicted image generation method when the prediction for every encoding target block as the prediction unit has been selected.

A first prediction region and a second prediction region, which are reference regions for the encoding target image, are set. A predicted image is generated based on the weighting coefficients, and a first primary-predicted image and a second primary-predicted image which are obtained based on the first and second prediction regions.

Abstract: When decoding code data of a video wherein each frame that forms the video is divided into a plurality of processing regions, each processing region is subjected to predictive decoding, a provisional decoded image obtained by provisional image decoding utilizing a low-resolution prediction residual is generated, and a final decoded image is generated by updating decoded values of the provisional decoded image. Additionally, when dividing each frame that forms a video into a plurality of processing regions and subjecting each processing region to predictive encoding in which a high-resolution prediction residual is subjected to downsampling to generate a low-resolution prediction residual, a subsampled prediction residual is generated by a subsampling process which subjects only part of pixels of the high-resolution prediction residual to sampling, and the subsampled prediction residual is determined to be the low-resolution prediction residual.
