Claim 6:
7. An image encoding method performed by an image encoding apparatus, the image encoding method comprising:
determining a splitting type of a current block;
splitting the current block into a plurality of lower-layer blocks based on the splitting type; and
encoding the lower-layer blocks and information on splitting of the current block,
wherein the determining the splitting type of the current block is performed by disallowing a predetermined type, in which a width or height of the lower-layer blocks is a predetermined value, among a plurality of splitting types,
wherein a vertical binary splitting type is disallowed as the splitting type of the current block regardless of a height of the current block, based on a tree structure of the current block being a dual tree structure and a width of the current block being 4, and
wherein a horizontal binary splitting type is not disallowed as the splitting type of the current block regardless of the width of the current block, based on the tree structure of the current block being the dual tree structure and the height of the current block being 4.
