Claim 3:
4. An image encoding apparatus comprising:
an encoder configured to:
when a size of a first coding block of a first color component is equal to or smaller than a predetermined size, split the first coding block according to a first split mode, and split a second coding block of a second color component according to a second split mode;
encode a third coding block obtained as a result of the splitting of the first coding block;
encode a fourth coding block obtained as a result of the splitting of the second coding block; and
a generator configured to generate a bitstream comprising first split shape mode information indicating the first split mode, second split shape mode information indicating the second split mode, a result of the encoding of the third coding block, and a result of the encoding of the fourth coding block,
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.
