1. An intra prediction method, applicable to a decoder, the method comprising:
parsing a bitstream, and determining a target prediction mode of a current picture block in a current picture sequence, wherein the target prediction mode is a first prediction mode or a second prediction mode, the first prediction mode is an intra prediction mode for the decoder to derive the current picture block by using a manner of an encoder deriving the intra prediction mode, and the second prediction mode is a prediction mode combining the first prediction mode with a Matrix based Intra Prediction (MIP) mode; and
performing intra prediction on the current picture block based on the target prediction mode, to obtain a target prediction block of the current picture block.
