Original Abstract Submitted
devices and methods of directional intra prediction for chroma component of a picture are provided. the method includes obtaining an initial intra prediction mode of the chroma component, and deriving a chroma intra prediction mode (intrapredmodec) from a look up table (lut) by using the initial intra prediction mode of the chroma component. the chroma component has different subsampling ratios in horizontal and vertical directions. the method further includes performing wide-angle mapping on the chroma intra prediction mode (intrapredmodec) to obtain a modified intrapredmodec; obtaining an angle parameter for the chroma component based on the modified intrapredmodec; and obtaining predicted samples of the chroma component based on the angle parameter. the method provides the minimum number of entries in the lut that is used to determine chroma intra prediction mode from the initial chroma intra prediction mode.
