1. An image decoding method, the method comprising:
receiving a bit stream including information related with first intra prediction mode information indicating a first intra prediction mode of a first reference block in a current picture and second intra prediction mode information indicating a second intra prediction mode of a second reference block in the current picture; and
performing an adaptive decoding for a target block based on the bit stream received,
wherein the adaptive decoding determines an intra prediction mode of the target block based on both of the first intra prediction mode of the first reference block and the second intra prediction mode of the second reference block, and performs the decoding for the target block based on the determined intra prediction mode of the target block,
wherein the first reference block is a block adjacent to the left of the target block and the second reference block is a block adjacent to the above of the target block, and
wherein a respective intra prediction mode of a respective reference block is not used for determining the intra prediction mode of the target block if the respective reference block is located outside a boundary of a slice to which the target block belongs.
