Abstract
A method of decoding an image according to the present disclosure includes determining whether an inverse transform is skipped to a current block, parsing information on a residual coefficient of the current block, reconstructing the residual coefficient by inversely binarizing the information and selectively applying the inverse transform to the residual coefficient. In this case, the inverse binarization may be performed based on a rice parameter for the residual coefficient and the rice parameter may be derived based on a first variable derived based on a sum of absolute values of reference residual coefficients.
