1. A method of decoding image data, the method comprising:
acquiring, from a bitstream including a coded picture of the image data, image information of a current block in the coded picture; and
decoding the current block based on the image information,
wherein decoding the current block comprises:
constructing a motion vector candidate list, the motion vector candidate list including a plurality of motion vector candidates;
determining a motion vector of the current block based on the motion vector candidate list and index information, the index information specifying one of the plurality of the motion vector candidates;
generating a prediction signal of the current block by performing a motion compensation on the current block based on the determined motion vector; and
reconstructing the current block by summing a residual signal of the current block and the prediction signal, the residual signal being acquired from the bitstream, and
wherein the motion vector candidate list includes a motion vector of a pre-decoded block which is not adjacent to the current block and belongs to the same coded picture as the current block.
