Abstract
Chroma intra prediction methods and devices are provided. The method comprising: parsing bitstream data corresponding to a current chroma block, and determining that a prediction mode corresponding to the current chroma block is DM; before determining a set of chroma prediction modes based on at least one modified candidate mode, acquiring a linear mode corresponding to the current chroma block from the bitstream data; determining an intra prediction mode of the current chroma block from the set of chroma prediction modes, wherein the set of chroma prediction modes comprises at least one of the DM, LM, LM_T or LM_L, wherein when a luma prediction mode corresponding to the DM is a DC mode or a planar mode, the set of chroma prediction modes comprises a diagonal angular mode with prediction direction index number 66, determining a reconstructed value of the current chroma block according to the intra prediction mode.
