1. A method of generating a candidate list of candidates for motion information generated in image decoding, comprising:
generating the candidate list including motion information generated using information of a neighboring block adjacent to a current block;
deriving motion information of the current block using the candidate list;
generating a prediction block of the current block using the derived motion information of the current block; and
updating a motion information list to store the derived motion information of the current block,
wherein the candidate list includes at least one of motion information included in the motion information list used for a block decoded before decoding for the current block, and
wherein the derived motion information for the current block is stored in the motion information list to be used for Intra Block Copy (IBC) mode when a size of the current block is greater than or equal to a first predetermined size and the size is less than or equal to a second predetermined size.
