    Abstract: The present technique relates to a decoding device and a decoding method, and an encoding device and an encoding method, capable of performing encoding and decoding independently in the time direction for each tile. A decoding unit generates a prediction image by performing, for each of tiles, motion compensation of a reference image within a co-located tile based on tile splittable information indicating that decoding is allowed for each of the tiles and motion vector information representing a motion vector used for generating encoded data of a decoding target current image when a picture of the current image is split into the tiles and decoded. The decoding unit decodes the encoded data using the prediction image. The present technique is applicable to a decoding device, for example.

    Abstract: An image processing apparatus including an inter-prediction section that generates a set of reference pixels of fractional pixel positions from a reference image for motion compensation and searches an image to be encoded for a motion vector by using the set of generated reference pixels and an encoding section that encodes the image to be encoded on a basis of a result of searching for the motion vector by the inter-prediction section. The inter-prediction section includes a reference pixel at a fractional pixel position further inward than a first predetermined distance from a boundary of a partial region corresponding to a slice or a tile, in the set of reference pixels that are used for searching the partial region for a motion vector.

    Abstract: In a sample adaptive offset (SAO), the coding efficiency is improved by selecting an optimum mode among a plurality of modes based on a technique called a band offset and an edge offset. However, a processing amount of the SAO tends to increase when an optimum mode and an offset value are set, and this may result in an increase in a circuit size or power consumption. In this regard, the present disclosure proposes to enable reducing a processing amount of a cost calculation of the sample adaptive offset. According to the present disclosure, there is provided an image processing apparatus, including: a control unit configured to set an offset value to be applied to a pixel of an image, from among candidates of the offset value restricted according to a bit depth of the image; and a filter processing section configured to perform a filter process of applying the offset value set by the control unit to the pixel of the image.

    Abstract: The present technology relates to an encoding device and an encoding method, and a decoding device and a decoding method configured to reduce an encoding amount of the encoded stream when information regarding a depth image is included in the encoded stream.A DPS encoding unit sets depth image information, which is information regarding a depth image, as a DPS different from a sequence parameter set and a picture parameter set. A slice encoding unit encodes the depth image to generate encoded data. Further, the slice encoding unit transmits an encoded stream including the DPS and the encoded data. The present technology can be applied to, for example, a multi-view image encoding device.
