1. A method of decoding an image, the method comprising:
constructing a first candidate list of a current block in the image, the first candidate list including a plurality of merge candidates;
generating a first prediction block of the current block by performing inter prediction based on one of the plurality of merge candidates included in the first candidate list;
generating a second prediction block of the current block based on a pre-defined intra prediction mode in a decoding apparatus, the pre-defined intra prediction mode being representative of a Planar mode;
generating a final prediction block of the current block based on a weighted sum of the first prediction block and the second prediction block; and
reconstructing the current block based on the final prediction block of the current block,
wherein a weight for the weighted sum is determined based on a prediction mode of a neighboring block of the current block,
wherein the first candidate list includes a merge candidate having motion information of a previously decoded block,
wherein the merge candidate having the motion information of the previously decoded block is derived from a second candidate list, and
wherein the second candidate list is constructed based on motion information of previously decoded blocks.
