摘要

The intra prediction parameter used in the intra-frame prediction process of the color difference signal in the prediction block is YUV 4: 2: 2 in the signal format of the color image, and the prediction mode The intraprediction unit 4 converts the index indicating the intra prediction mode for the luminance signal and performs intra prediction processing of the color difference signal in the intra prediction mode indicated by the index after conversion Conduct.
