Title:
Restoration block generation method
Document Type and Number:
Japanese Patent JP6367413
Kind Code:
B2
Abstract:
Provided is a method that derived 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, generating a residual block of the current block according to the intra prediction mode and generating a reconstructed block of the current block using a prediction block and a residual block. The sizes of the prediction block and the residual block are set equal in size of a transform unit. Therefore, the distance of intra prediction becomes short, and the amount of coding bits of residual block is reduced by generating a prediction block very similar to original block. Also, the signaling bits required to signal intra prediction mode decrease by generating MPM group adaptively according to the neighboring intra prediction modes.
