Classification: CPC H  G | IPC G  H

Claim 6:
7. An image encoding method performed by an image encoding apparatus, the image encoding method comprising:
determining a block division type of a current block in an image from a candidate group pre-defined in the image encoding apparatus, index information for specifying the determined block division type of the current block being encoded into a bitstream;
dividing the current block into a plurality of sub-blocks based on the determined block division type; and
encoding each of the sub-blocks to encode the current block,
wherein the candidate group includes at least one of a non-division, a first quad-division, a second quad-division, a binary-division or a triple-division, and
wherein the first quad-division divides one coding block into four coding blocks based one horizontal line and one vertical line, the second quad-division divides one coding block into four coding blocks based on three horizontal lines or three vertical lines, the binary-division divides one coding block into two coding blocks, and the triple-division divides one coding block into three coding blocks.
