1. An image decoding method comprising:
acquiring combined inter intra prediction (CIIP) mode information from a bitstream;
determining whether a current block is in a CIIP mode based on the CIIP mode information;
deriving a CIIP block by combining an intra prediction block and an inter prediction block of the current block using a weight, based on a determination of the current block being in the CIIP mode; and
generating a reconstructed block of the current block based on the CIIP block,
wherein, when the CIIP mode information is not acquired from the bitstream and the current block is in a skip mode, the CIIP mode information is regarded as a value indicating that the current block is not in the CIIP mode, and
wherein the weight is derived based on whether a neighboring block of the current block is available and whether the neighboring block is in the intra prediction mode.
