摘要： 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.

摘要： 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.

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.
