PROBLEM TO BE SOLVED: To provide a preferable method of generating a reconstructed block.SOLUTION: An embodiment derives an intra prediction mode of a prediction unit, determines a size of a current block using transform size information, generates a prediction block of the current block according to the intra prediction mode, generates a residual block of the current block according to the intra prediction mode and generates a reconstructed block of the current block using the prediction block and the residual block. The sizes of the prediction block and the residual block are equal to the size according to size information of a transform unit. Therefore, the distance of intra prediction becomes short, allowing generation of a prediction block similar to the original block so as to reduce the coding amount of the residual block. In addition, the signaling bits for sending the intra prediction mode can be reduced by generating the MPM adaptively according to the neighboring intra prediction modes. |
