Abstract

A method for decoding an image according to the present invention comprises the steps of: receiving a bit stream; deriving decoding information by entropy-decoding the bit stream; and generating a restoration block corresponding to a decoding target block based on the decoding information. According to the present invention, the image encoding/decoding efficiency is improved and complexity can be reduced.
