Abstract
An image decoding apparatus can include a prediction mode decoding module for deriving luma intra prediction mode and chroma intra prediction mode; a prediction size determining module for determining a size of a luma transform unit and a size of a chroma transform unit; a reference pixel generating module for generating a reference pixel when at least one reference pixel is unavailable; a reference pixel filtering module for adaptively filtering a reference pixel of a current luma block based on the luma intra prediction mode and the size of the luma transform unit, wherein a reference pixel of a current chroma block is not filtered; a prediction block generating module for generating prediction blocks of the current luma block and the current chroma block; and a residual block generating module for generating a luma residual block and a chroma residual block.
