The present technique relates to an image processing apparatus, an image processing method, and a program capable of obtaining a vector with a high degree of prediction accuracy as a prediction vector. A prediction vector generation unit generates a prediction vector of a deviation vector representing deviation of a target block, which is a processing target in a depth image having depth information about parallax as a pixel value for each pixel of a color image, with respect to another picture different from a picture of the target block. The prediction vector generation unit generates the prediction vector in accordance with a vector prediction method which is different depending on whether the target block is an occlusion block including an occlusion portion that does not include any corresponding point in another picture. The present invention can be applied to, for example, a case of generating a prediction vector of a parallax vector used to generate a prediction image for encoding and decoding of a depth image about parallax.

The present invention relates to a playback device, a playback method, and a program, which enable a 3D content to be played by determining which stream of a basic stream and an extended stream is a left image stream in the event of displaying a 3D image for example. In the event that the value of view_type is 0, of the data stored in a DPB 151, data obtained by decoding a Base view video packet which is identified by PID=0 is output to an L video plane generating unit 161. The value 0 of the vie and w_type represents that a Base view video stream is an L view stream. In this case, data obtained by decoding a Dependent view video packet which is identified by a PID other than 0 is output to an R video plane generating unit 162. The present invention can be applied to a playback device compatible with the BD-ROM standard.

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.

The present technology relates to an image processing device and image processing method, enabling improvement of prediction efficiency of disparity prediction. A converting unit converts a reference image, of a different viewpoint from an image to be encoded, which is referenced at the time of generating a prediction image of the image to be encoded which is to be encoded, by controlling filter processing applied to the reference image in accordance with the reference image and resolution information relating to resolution of the image to be encoded, so that the reference image is converted in to a converted reference image of a resolution ratio agreeing with a horizontal and vertical resolution ratio of the image to be encoded. A disparity compensating unit generates a prediction image by performing disparity compensation using the converted reference image, and the image to be encoded is encoded using that reference image. The present technology can be applied to, for example, encoding and decoding of images of multiple viewpoints.

A warping unit 461 warps a picture of an image of a viewpoint #1 between the image of the viewpoint #1 and an image of a viewpoint #2 different of the viewpoint #1 to generate a picture of a warped image obtained by converting the picture of the image of the viewpoint #1 into an image obtainable in the viewpoint #2. A disparity prediction unit 463 acquires, from header information, a reference index indicating a reference picture that is referred to generate a predicted image of an object block to be decoded of a picture of the image of the viewpoint #2, and selects the reference picture from among reference picture candidates including at least the picture of the warped image based on the reference index. The present technology is applicable, for example, to coding and decoding of images from multiple viewpoints.
