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.

摘要： The present invention relates to an image processing apparatus and method that can generate a high-accuracy prediction image with a small amount of control information. A motion compensation circuit (51) specifies a macroblock corresponding to a prediction image in a reference frame other than a current frame using a motion vector supplied from a prediction mode determination circuit (41). The motion compensation circuit (51) reads an image of the specified macroblock from a frame memory (19), and extracts the read image as a motion compensation image. An intra-prediction circuit (52) performs intra-prediction on the current frame using an arbitrary method to generate an intra-prediction image IP. The present invention can be applied to, for example, an encoding apparatus and a decoding apparatus.

摘要： 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.
