1. An image encoding method comprising:
generating a prediction block of a current block included in a current picture based at least in part on motion information of the current block;
generating a residual block based on the current block and the prediction block;
determining whether transform skip is applied to the current block or not as transform skip information;
encoding the motion information of the current block and the transform skip information,
wherein the current block is encoded by referring to a spatially neighboring block or a temporally neighboring block,
wherein the temporally neighboring block is determined by selecting one block among maximum two candidate blocks included in a reference picture based on encoding parameters of the maximum two candidate blocks, the encoding parameters including reference picture indices for the maximum two candidate blocks, the reference picture being different from the current picture, the maximum two candidate blocks including a collocated block of the current block and a block spatially adjacent to the collocated block, and the encoding parameters being included in a bitstream, and
wherein, in case the current block is encoded by referring to the temporally neighboring block, the temporally neighboring block has the same motion information as the current block; and
transmitting the encoding parameters, as included in the bitstream, from an image encoding device to an image decoding device.
