Encoding/decoding method and apparatus using a tree structure
A method for reconstructing image information divided by a tree structure from a bitstream, includes: decoding the bitstream to reconstruct additional information, the additional information including first information on a minimum block size and second information on a difference between the minimum block size and a maximum block size, wherein the difference between the minimum block size and the maximum block size is a value of a log scale; reconstructing a partition flag indicating whether or not each node, starting from a node of an uppermost layer of the tree structure, is divided into nodes of a lower layer, the node of the uppermost layer identified based on the first and second information; and reconstructing image information of a block corresponding to a node which is not further divided.
