Claim 8:
9. The method according to claim 8, wherein the method further comprises:
obtaining a reconstructed block of the at least one neighbouring block, wherein the reconstructed block is obtained by prediction based on a wide-angle intra prediction mode corresponding to a second intra prediction mode index of the at least one neighbouring block, and the second intra prediction mode index of the at least one neighbouring block is obtained by mapping, based on a width to height ratio of the at least one neighbouring block, the first intra prediction mode index of the at least one neighbouring block to an intra prediction mode index of the wide-angle intra prediction mode; and
obtaining the prediction block based on the target intra prediction mode corresponding to the second intra prediction mode index of the current block and the reconstructed block of the at least one neighbouring block.
