摘要： The present technique relates to an image processing device and an image processing method for realizing accurate depth image warping operations on the receiving end when depth images with reduced resolutions are transmitted. A partial resolution converting unit reduces resolutions of parallax images of auxiliary images. A partial conversion information generating unit generates partial conversion information. The parallax images having the resolutions reduced by the partial resolution converting unit and the partial conversion information generated by the partial conversion information generating unit are transmitted to a decoding device. The present technique can be applied to encoding devices that encode glasses-free 3D images, for example.

摘要： The present technology relates to an encoding device and encoding method, and a decoding device and a decoding method whereby the data amount of encoded data of images of multiple viewpoints can be reduced. A low-resolution reference image generating unit performs, in the event of encoding a color image of a viewpoint B having lower resolution than the resolution of a color image of a viewpoint A, different from the viewpoint A, resolution reduction processing to reduce resolution on the image of the viewpoint A so that the resolution of the color image of the viewpoint A agrees with the resolution of the color image of the viewpoint B. An inter prediction unit generates a prediction image of the color image of the viewpoint B with reference to the color image of the viewpoint A after resolution reduction processing. A computing unit and so forth encode the color image of the viewpoint B using the prediction image. The present technology may be applied to a 3D-image encoding device, for example.

摘要： The present technology relates to an image processing device and image processing method whereby prediction efficiency of disparity prediction can be improved. A resolution converting device converts images of two viewpoints or more, out of images of three viewpoints or more, into a packed image, by performing packing following a packing pattern in which images of two viewpoints or more are packed into one viewpoint worth of image, in accordance with a predetermined encoding mode at the time of encoding an image to be encoded which is to be encoded. An encoding device generates a prediction image of the image to be encoded, by performing disparity compensation with the packed image as the image to be encoded or a reference image, and encodes the image to be encoded in the predetermined encoding mode, using the prediction image. The present technology can be applied to encoding and decoding of images of multiple viewpoints, for example.

摘要： The present invention relates to an encoding device, an encoding method, a decoding device, and a decoding method capable of encoding and decoding multi-viewpoint images in accordance with a mode that is compatible with an existing mode.A compatible encoder generates a compatible stream by encoding an image A1 that is a compatible image in units of access units. An auxiliary encoder generates an encoded stream of a multiplexed image of auxiliary images by encoding a multiplexed image of images B1 and C1 that are auxiliary images used when multi-viewpoint images are generated from the compatible image in units of access units. A multiplexing unit transmits the compatible stream, a 3DV Representation Delimiter representing a boundary of a unit, and an encoded stream of the multiplexed image of the auxiliary images. The present technology can be applied to, for example, an encoding device that encodes a 3D image of the multi-viewpoint mode.

摘要： A multiview video decoding apparatus receives and decodes an encoded stream obtained as a result of encoding residual information, 2D images for N views, and depth images for N views, the residual information being the error between synthetic-view images generated using the 2D images for N views and the depth images for N views, and 2D images for (M−N) views at the view synthesis positions of the synthetic-view images. A view synthesizing apparatus generates the synthetic-view images by using the 2D images and depth images for N views decoded by the multiview video decoding apparatus. A residual information compensating apparatus adds the residual information into the generated synthetic-view images. The apparatus may be applied to a system that conducts view synthesis, for example.
