Claim 9:
10. An image encoding method performed by an image encoding apparatus, the image encoding method comprising:
determining an intra prediction mode of a current block;
generating a prediction block of the current block by performing an intra prediction for the current block based on the intra prediction mode;
encoding a first flag indicating whether an MPM mode is applied for the current block;
encoding, based on a value of the first flag, a second flag indicating whether the intra prediction mode of the current block is a Planar mode; and
encoding, based on a value of the second flag, the intra prediction mode of the current block,
wherein the encoding the second flag is performed based on whether a reference sample line used for the intra prediction of the current block is a first reference sample line directly adjacent to the current block.
