Method for encoding/decoding image, and device using same
A method for decoding an image, and a device using the same are disclosed. The method for decoding an image comprises the steps of: inducing a chroma component block corresponding to a luma component block on the basis of chroma format information indicating chroma component sampling corresponding to luma component sampling; dividing the chroma component block into transformation blocks of a chroma component for transformation on the basis of division information indicating whether a first block has been divided into second blocks for transformation; and acquiring residual information on the transformation blocks of the chroma component by performing at least one of inverse transformation and inverse quantization on the basis of the transformation blocks of the chroma component.
