1. A method for decoding a picture using a derivation of an inter-view merge candidate, the method comprising:
deriving an inter-view reference block using a disparity vector of a current block;
determining whether motion information exists in the inter-view reference block;
generating an inter-view motion merge candidate for the current block based on whether the motion information exists in the inter-view reference block;
generating a merge candidate list for the current block using the inter-view motion merge candidate; and
generating a prediction block for the current block based on the merge candidate list,
wherein when it is determined that the motion information exists in the inter-view reference block, the inter-view motion merge candidate is generated by using motion information of the inter-view reference block,
wherein when it is determined that the motion information does not exist in the inter-view reference block, the inter-view motion merge candidate is generated by using motion information of a neighboring block of the inter-view reference block, and
wherein the neighboring block of the inter-view reference block is fixed to a block located in a center of an object region including the inter-view reference block.
