Claim 18:
19. The method of claim 14, wherein the intra prediction mode candidate list of the current block is derived as a third intra prediction mode candidate list based on a determination that the first candidate intra prediction mode is not equal to the second candidate intra prediction mode, both of the first and the second candidate intra prediction modes are not greater than a mode value of a DC intra prediction mode, and the sum of mode values of the first and second candidate intra prediction modes are greater than or equal to 2, and
wherein the third intra prediction mode candidate list is derived based on an intra prediction mode having a value obtained by subtracting 1 from a greater mode value of mode values of the first and second candidate intra prediction modes.
