摘要： The present technique relates to an image processing device and an image processing method for realizing accurate depth image warping operations at the receiving side when depth images with reduced resolutions are transmitted. A parallax image generating unit reduces the resolutions of parallax images B1′ and C1′. A boundary information generating unit generates boundary information about the parallax images B1′ and C1′. A multiplexing unit transmits a multiplexed stream containing the parallax images B1′ and C1′ with the reduced resolutions and the boundary information. The present technique can be applied to encoding devices that encode glasses-free 3D images, for example.

摘要： The present technique relates to an image processing device and a method that can improve encoding efficiency in multi-viewpoint encoding. A reference image index allocation unit alternately allocates a reference image index referred by a motion estimator/compensator to predict an image to be processed to a referable image in a view direction and to a referable image in a time direction. In allocation, the reference image index allocation unit refers to time information and view information of the reference image accumulated in a decoded picture buffer, information such as a sequence parameter set and a slice header from a syntax processing unit, and the like.

摘要： The present technology relates to an encoding device, an encoding method, a decoding device, and a decoding method capable of suppressing the amount of information without degrading the image quality of an image of a viewpoint that is used when the compatibility is secured in a case where a multi-viewpoint image is encoded. A compatible encoder generates a compatible stream by encoding an image A1 that is a compatible image. An image converting unit lowers the resolution of images B1 and C1 that are auxiliary images. An auxiliary encoder generates an encoded stream of the auxiliary image by encoding the auxiliary image of which the resolution is lowered. A multiplexing unit transmits the compatible stream and the encoded stream of the auxiliary image. The present technology can be applied to, for example, an encoding device that encodes a 3D image of the multi-viewpoint mode.

摘要： The present technique relates to an image processing device and an image processing method for realizing high-precision image generation of predetermined viewpoints by using depth images on the receiving end when the depth images with reduced resolutions are transmitted.A parallax image resolution increasing unit increases the resolution of each of the parallax images of auxiliary images having half the resolution of a compatible image. A parallax image warping unit generates parallax images of virtual viewpoints by performing a warping operation on the parallax images of the auxiliary images with the increased resolutions based on the positions of the virtual viewpoints. A smoothing unit corrects the parallax values of the occlusion regions in the parallax images of the virtual viewpoints. The present technique can be applied to decoding devices that decode 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.
