1. A decoding apparatus for image decoding, the apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
obtain a coding block by partitioning an image;
determine whether a size of the coding block belongs to a predetermined range;
determine a split type for the coding block based on whether the size of the coding block belong to the predetermined range;
derive a current block split from the coding block based on the split type for the coding block; and
reconstruct the current block,
wherein based on that the size of the coding block belongs to the predetermined range, the split type for the coding block represents that the coding block is split into two or four equal-sized subblocks based on quad-tree split or binary-tree split,
wherein based on that the size of the coding block is equal to a first size, the split type for the coding block is implicitly determined as that the coding block is split into the four equal-sized subblocks, and
wherein based on that the size of the coding block is equal to a second size, the split type for the coding block is implicitly determined as that the coding block is split into the two equal-sized sub-blocks.
