Abstract
An image decoding method according to the present disclosure includes determining a reference pixel line of a current block, determining an intra prediction mode of the current block and deriving a prediction sample of the current block based on the intra prediction mode and a reference pixel included in the reference pixel line. In this case, the prediction sample is determined based on a prediction angle of the intra prediction mode and an inverse-angle variable derived based on the prediction angle. And when the prediction angle has a predefined value, the inverse-angle variable is set as a default value.
