Original Abstract Submitted

disclosed are an inter prediction mode-based image processing method and an apparatus therefor. particularly, a method for processing an image on the basis of inter prediction may comprise the steps of: determining whether a motion vector scale adaptation is applied to a block; up-scaling a down-scaled mvd(motion vector difference) when the motion vector scale adaptation is applied to the block; deriving a mv(motion vector) for the block, using the up-scaled mvd and a mvp(motion vector predictor); and generating a predictive block of the block, using the derived mv.
