1. An image decoding method, the method comprising:
determining transform partition information applied for a transform block;
determining a current transform block using the transform partition information; and
performing inverse-transform on the current transform block,
wherein the current transform block is a sub transform block partitioned from an upper layer transform block, the sub transform block being a block partitioned from the upper layer transform block by at least one of a quad tree partition or a binary tree partition,
wherein whether to partition the upper layer transform block into the sub transform block is determined based on at least one of a width or a height of the upper layer transform block, and
wherein the inverse-transform is performed within a predetermined transform performing area of the upper layer transform block.
