摘要:
The present invention relates to an image processing device and method that enable generation of a highly precise prediction image using a small amount of control information. A motion compensation circuit 51 specifies a macroblock corresponding to a prediction image in part of reference frames using a motion vector supplied from a prediction mode determination circuit 41, reads an image thereof from a frame memory 19, and extracts it as a motion compensation image. A motion prediction circuit 52 reads, from a frame memory 122, at least one or more of the remaining reference frames, performs motion prediction of the motion compensation image MC0 supplied from the motion compensation circuit 51 in each frame, reads an image of a macroblock that matches or is similar to the motion compensation image MC0 from the frame memory 122, and extracts it as a motion compensation image. The present invention can be applied to, for example, an encoding device and a decoding device.

The present disclosure relates to an image processing apparatus and an image processing method that are capable of improving coding efficiency at the time when a prediction using a correlation within a screen is performed. A predicted vector generation section sets, at a time of encoding of a current motion vector of a current block for a prediction using a correlation within a screen, in a case where a type of a reference picture of the current block and a type of a reference picture of a candidate block corresponding to a candidate of a reference motion vector are different from each other, the candidate block to not available and generates a predicted vector of the current motion vector by using the reference motion vector, the reference motion vector being referred to when the predicted vector of the current motion vector is generated. A difference vector generation section generates a difference vector between the current motion vector and the predicted vector generated by the predicted vector generation section. The present disclosure can be applied to, for example, an encoding apparatus.

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.

The present disclosure relates to an information processing apparatus and an information processing method that enable recognition of performance required for decoding more accurately. A file of an MP4 file format, in which information specifying a plurality of NAL units corresponding to a partial image which can be independently decoded in a whole image is stored in moov and the encoded partial image is stored in mdat, is generated, and the generated file is transmitted. The present disclosure can be applied to, for example, an information processing apparatus such as an image encoding apparatus or an image decoding apparatus.

The present disclosure relates to an image processing device and method that enable improvement in processing efficiency in encoding or decoding. A type E0 of an LCU 115 and its coefficient are determined on the encoder side. The coefficient of the type E0 was sent to the decoder side at the time of the LCU 111, and has been stored in an EO buffer included in an adaptive offset filter on the decoder side. For the LCU 115, therefore, a copy of the coefficient of the type E0 in the EO buffer is used on decoder side without the sending of the coefficient of the type E0. As described above, the parameters of the adaptive offset filter, which are transmitted in one batch at the beginning of a frame in the related art, are sent sequentially at the beginning of an LCU for each LCU. The present disclosure can be applied to, for example, an image processing device.

The present disclosure relates to an imaging processing apparatus and method by which degradation of the quality due to two-dimensional projection of 3D data can be suppressed. All pieces of data for each position included in 3D data representative of a three-dimensional structure are projected to a two-dimensional plane of plural layers. Further, all pieces of data for each position of 3D data projected to a two-dimensional plane having the number of layers indicated by layer number information are projected to a three-dimensional space. The present disclosure can be applied, for example, to an information processing apparatus, an image processing apparatus, electronic equipment, an information processing method, and a program.

The present disclosure relates to an information processing apparatus and a method that allow for suppression of a decrease in encoding efficiency. Correlation information is generated that results from encoding of voxel data resulting from quantization of point cloud data with use of correlation of a distribution pattern of values of the voxel data; the generated correlation information is encoded; and a bit stream including the correlation information is generated. The present disclosure is applicable to an information processing apparatus, an image processing apparatus, an electronic device, an information processing method, a program, or the like, for example.
