Abstract
Disclosed is a method for deriving a bidirectional prediction weight index of a constructed candidate included in an affine merge candidate list. The method comprises: determining whether a plurality of target control points are available from among control points set for a current block; if the target control points are available, then checking prediction directions and reference pictures of the target control points; and if the prediction directions of the target control points are all bidirectional and the reference pictures of the target control points are the same, then deriving the bidirectional prediction weight index of the constructed candidate from among bidirectional prediction weight index candidates of the target control points.
