1. An image decoding method, comprising:
obtaining one or more luma coding units based on at least one of a split direction and a split type of a luma block;
decoding a luma image based on the obtained one or more luma coding units;
when an area of a chroma block is smaller than or equal to an area predetermined according to tri split type of the chroma block, determining not to allow splitting of the chroma block according to the tri split type and obtaining one or more chroma coding units according to a split type except for the tri split type;
when the area of the chroma block is smaller than or equal to an area predetermined according to binary split type of the chroma block, determining not to allow splitting of the chroma block and obtaining one chroma coding unit included in the chroma block; and
decoding a chroma image based on the obtained one or more chroma coding units.
