    Abstract: The present technology relates to a decoding device and a decoding method, and an encoding device and an encoding method that enable images that configure a packed image to be reliably displayed when an encoded stream is decoded and displayed. A decoding unit decodes an encoded data, the encoded data being an encoded packed image in which a plurality of images is packed, and generates the packed image. A display control unit identifies the images that configure the packed image based on packing SEI preferentially used when the packed image is displayed. The present technology can be applied to a decoding device, for example.

    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: The present disclosure relates to an image processing apparatus and method that can keep reduction in coding efficiency to a minimum. A scaling list is set that has values appropriate to a current block size for the current block to be quantized in an image to be coded, quantization is performed using the set scaling list, and coded data is generated by coding an acquired quantization coefficient. The present disclosure is applicable, for example, to an image processing apparatus, an image coding apparatus, an image decoding apparatus, and so on.

    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.

    Abstract: There is provided an image processing device including a decoding section that decodes an encoded stream and generates quantized transform coefficient data, and an inverse quantization section that, taking transform coefficient data as transform units to be used during inverse orthogonal transform, inversely quantizes the quantized transform coefficient data decoded by the decoding section, such that in a case where a non-square transform unit is selected, the inverse quantization section uses a non-square quantization matrix, corresponding to a non-square transform unit, that is generated from a square quantization matrix corresponding to a square transform unit.
