Abstract
An image decoding method can include deriving luma intra prediction mode and chroma intra prediction mode, wherein the luma intra prediction mode is derived by using a prediction mode index, a mode group indicator, and an MPM (Most Probable Mode) group including three intra prediction modes; determining a size of a luma transform unit and a size of a chroma transform unit; generating a reference pixel when at least one of reference pixels is unavailable; adaptively filtering a reference pixel of a current luma block based on the luma intra prediction mode and the size of luma transform unit; generating prediction blocks of a current chroma block and the current luma block using the adaptively filtered reference pixel; generating residual blocks of the current chroma block and the current luma block; and generating a reconstructed block by adding the residual blocks and the prediction blocks.
