The method of claim 2, wherein if the second merge index is less than the first merge index, the second merge candidate is determined to be the merge candidate corresponding to a value equal to the second merge index among the merge candidates, and if the second merge index is greater than or equal to the first merge index, the second merge candidate is determined as the merge candidate corresponding to the value obtained by adding 1 to the second merge index among the merge candidates. 4. The method of claim 1, wherein the final prediction block is generated as a weighted sum of the first prediction block and the second prediction block. 5. The method of claim 4, wherein the final predicted sample in the final prediction block is generated by applying a first weight to the first predicted sample in the first prediction block and applying a second weight to the second predicted sample in the second prediction block. 6. The method of claim 5, wherein the first weight and the second weight are adaptively determined based on the position of the final predicted sample in the current block. 7.
