Abstract
An image decoding method performed by a decoding device according to the present disclosure comprises the steps of: deriving a predicted number of signs of a current block; performing sign prediction of the current block to derive as many signs of residual coefficients as the predicted number of signs; deriving residual samples of the current block on the basis of the signs; and generating a reconstructed picture on the basis of the residual samples.
