1. An image decoding method comprising:
obtaining, from a bitstream, information indicating whether a first coding block of a first color component and a second coding block of a second color component are split according to two separate trees;
when the obtained information indicating whether the first coding block and the second coding block are split according to the two separate trees indicates that the first coding block and the second coding block are split according to the two separate trees, and when a size of the first coding block is equal to or smaller than a predetermined size, obtaining, from the bitstream, first split shape mode information about the first coding block and second split shape mode information about the second coding block;
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 splitting the first coding block based on information obtained from the bitstream; and
decoding a fourth coding block obtained as a result of splitting the second coding block based on information obtained from the bitstream,
wherein when the obtained information indicating whether the first coding block and the second coding block are split according to the two separate trees indicates that the first coding block and the second coding block are not split according to the two separate trees, third split shape mode information is obtained from the bitstream, and the first coding block and the second coding block are split according to a third split mode determined from the third split shape mode information, and
wherein when the obtained information indicating whether the first coding block and the second coding block are split according to the two separate trees indicates that the first coding block and the second coding block are split according to the two separate trees, and 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.
