    • Disclosed are a method and a device for efficiently encoding and decoding an intra prediction mode for a prediction unit of a chrominance component by using an intra prediction mode for a prediction unit of a luminance component. According to one embodiment of the present invention, a method for encoding an intra prediction mode enables: intra prediction mode candidate groups of a prediction unit of a chrominance component to be reconfigured by excluding, from the intra prediction mode candidate groups, an intra prediction mode of the prediction unit of the chrominance component, which is overlapped with an intra prediction mode of a prediction unit of a luminance component, or by replacing the intra prediction mode with another intra prediction mode, depending on whether the intra prediction mode for the prediction unit of the luminance component is the same as predetermined intra prediction modes among the intra prediction mode candidate groups that are usable for the prediction unit of the chrominance component; and the intra prediction mode of the prediction unit of the chrominance component to be encoded by using the reconfigured intra prediction mode candidate groups.
    • 公开了一种用于通过针对亮度分量的预测单元使用帧内预测模式来高效地编码和解码用于色度分量的预测单元的帧内预测模式的方法和设备。 根据本发明的一个实施例,一种用于编码帧内预测模式的方法使得能够通过从帧内预测模式候选组中排除帧内预测模式来重新配置色度分量的预测单元的帧内预测模式候选组 与亮度分量的预测单元的帧内预测模式重叠的色度分量的预测单元的预测单元,或者通过用另一个帧内预测模式替换帧内预测模式,取决于预测单元的帧内预测模式 的亮度分量与可用于色度分量的预测单元的帧内预测模式候选组中的预定帧内预测模式相同; 以及通过使用重新配置的帧内预测模式候选组进行编码的色度分量的预测单元的帧内预测模式。
