摘要： The present technology relates to an image processing apparatus and an image processing method capable of improving an encoding efficiency of a parallax image using information with regard to the parallax image.A depth correction unit performs a depth weighting prediction process using a depth weighting coefficient and a depth offset based on a depth range indicating a range of a position in a depth direction, which is used when a depth value representing the position in the depth direction as a pixel value of a depth image is normalized, with the depth image as a target. A luminance correction unit generates a depth prediction image by performing a weighting prediction process using a weighting coefficient and an offset after the depth weighting prediction process is performed. A target depth image to be encoded is encoded using a depth prediction image and a depth stream is generated. The present technology can be applied to, for example, an encoding apparatus of a depth image.

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 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.
