    Abstract: The present disclosure relates to an image encoding device and a method, and an image decoding device and a method that are designed to improve encoding efficiency in IntraBC. In an example according to the present technology, a screen is divided into four slices (Slices #0 through #3). In a case where reference to a different slice is prohibited, the range that can be referred to from the current CTU in Slice #2 is only the decoded portion in Slice #2, and therefore, any block in Slice #1 cannot be referred to, for example. In the case of the present technology, on the other hand, decoded different slices (Slice #0 and Slice #1) are included in the referable range, and accordingly, a block in Slice #1 can be referred to from the current CTU in Slice #2, for example, as shown in FIG. 5. The present disclosure can be applied to image processing devices, for example.

    Abstract: The present disclosure relates to an image processing apparatus and a method that enable efficient change of reference relationship of views in multi-view coding. In the present technology, as for inter-view reference images, a used_by_curr flag is also set to an image having a possibility of being referred, in a slice header or syntax of an SPS. Only an image with the used_by_curr flag of 1 is added to a temporal list used in generating a reference list. Therefore, the temporal list (RefPicListTemp0[rIdx]) of L0 is generated in an order of a short-term (before) reference image of an index 0, a short-term (after) reference image of an index 1, and inter-view reference images of indexes 2 and 3. The present disclosure can be applied to an image processing apparatus, for example.

    Abstract: The present disclosure relates to an image processing apparatus and a method that can more easily improve encoding efficiency. A packing processing unit configured to perform packing processing of rearranging pixel data of RAW data that is image data before demosaicing processing is performed according to the degree of correlation, and an encoding unit configured to encode the RAW data subjected to the packing processing by the packing processing unit are included. The present disclosure can be applied to image processing apparatuses such as an image encoding device that encodes the RAW data and an image decoding device that decodes encoded data that is encoded RAW data.

    Abstract: The present disclosure relates to an image processing device and an image processing method capable of reducing a processing amount.A selection unit selects a plurality of reference pictures having mutually-different reference picture types from reference pictures represented by reference picture specifying information included in a reference list based on restriction identification information identifying that the reference list that is a list of reference picture specifying information specifying reference pictures of a current picture is used commonly within the current picture. A predicted image generating unit generates a predicted image of the current picture based on a motion vector of a collocated picture of time different from that of the current picture and a reference picture of a same reference picture type as a reference picture type of the collocated picture among the plurality of reference pictures selected by the selection unit.

    Abstract: The present technology relates to an information processing device and a method capable of adaptively providing a partial image of an image in each layer of an image constituted by a plurality of layers. The information processing device of the present technology generates a file that stores information on a whole of a base layer of encoded data produced by layer encoding of image data, information on each of partial areas of an image of the base layer, information on a whole of an enhancement layer of the encoded data, and information on each of partial areas of an image of the enhancement layer such that each of the information is stored in corresponding one of tracks different from each other. The present technology is applicable to an information processing device, an image processing device, an image encoding device, or an image decoding device, for example.
