1. A decoding apparatus for image decoding, the decoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
obtain image information including partitioning information;
determine whether a current block is partitioned based on a number of samples of the current block; and
decode the current block based on whether the determined current block is partitioned,
wherein the partitioning information includes a first flag indicating whether the current block is partitioned as quad-tree (QT) type, and
based on a value of the first flag being 0, the partitioning information includes a second flag and a third flag, the second flag indicates a partitioning direction of the current block, and the third flag indicates whether a partition type of the current block is a binary-tree (BT) type or ternary-tree (TT) type.
