摘要:
This technology relates to an image processing device and an image processing method capable of collectively encoding a color image and a depth image of different resolutions.An image frame converting unit converts the resolution of the depth image to the same resolution as that of the color image. An additional information generating unit generates additional information including information to specify the color image, or information to specify the depth image, image frame conversion information indicating an area of a black image included in the depth image, the resolution of which is converted, and resolution information to distinguish whether the resolutions of the color image and the depth image are different from each other. This technology may be applied to the image processing device of images of multiple viewpoints, for example.

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.

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. The present disclosure can be applied to image processing devices, for example.

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.
