Abstract

Disclosed in the embodiments of the present application are an image encoding method, an image decoding method, and related apparatuses. The image decoding method comprises: dividing an image, and determining a chrominance component intra-frame prediction mode of a current encoding block; determining, according to the chrominance component intra-frame prediction mode, a prediction block of a chrominance component of the current encoding block; and performing prediction correction on the prediction block of the chrominance component of the current encoding block and obtaining a corrected prediction block of the chrominance component of the current encoding block. In the embodiments of the present application, a prediction sample of a chrominance component of a current encoding block is corrected by using the spatial association between an adjacent encoding block and the current encoding block in a chrominance component intra-frame prediction mode, thus improving the prediction accuracy and encoding efficiency.
