1. A method for processing an intra prediction mode, comprising:
determining, by an apparatus, whether an intra prediction mode of a first neighboring block is the same as an intra prediction mode of a second neighboring block, wherein the first neighboring block is on a left side of a current block and the second neighboring block is on an upper side of the current block, wherein:
in case that the intra prediction mode of the first neighboring block is the same as the intra prediction mode of the second neighboring block, and the intra prediction mode of the first neighboring block is direct current (DC) prediction mode or planar prediction mode, most probable modes (MPMs) include DC prediction mode and planar prediction mode; or
in case that the intra prediction mode of the first neighboring block is the same as the intra prediction mode of the second neighboring block, and the intra prediction mode of the first neighboring block is not DC prediction mode and planar prediction mode, MPMs include directional intra prediction modes; and
performing intra prediction for the current block based on an intra prediction mode of the MPMs.
