Original Abstract Submitted
An intra prediction method includes the following. A first intra prediction mode and a second intra prediction mode for a current block are determined. A weighted blending condition for the current block is determined according to an image content of a current sequence, where the weighted blending condition is used to determine whether weighted prediction is performed on the current block based on the first intra prediction mode and the second intra prediction mode. A target prediction value of the current block is determined according to the weighted blending condition and at least one of the first intra prediction mode or the second intra prediction mode.
