1. An image decoding method comprising:
when a size of a first coding block of a first color component is equal to or smaller than a predetermined size, obtaining, from a bitstream, first split shape mode information about the first coding block and second split shape mode information about a second coding block of a second color component;
splitting the first coding block according to a first split mode determined from the first split shape mode information;
splitting the second coding block according to a second split mode determined from the second split shape mode information;
decoding a third coding block obtained as a result of the splitting of the first coding block based on information obtained from the bitstream; and
decoding a fourth coding block obtained as a result of the splitting of the second coding block based on information obtained from the bitstream,
wherein when the size of the first coding block is greater than the predetermined size, the first coding block and the second coding block are split according to a predetermined split mode,
wherein the first split mode comprises one of a quad-split mode, a binary-split mode and a ternary-split mode, and
wherein the second split mode comprises one of the quad-split mode, the binary-split mode and the ternary-split mode.
