Zusammenfassung:	The present disclosure provides an apparatus and a method for generating an inter-prediction frame, and an apparatus and a method for interpolating a reference frame used therein. The apparatus for interpolating the reference frame includes a directivity determiner for determining directivity of a quarter pixel located at the intersection of a left diagonal line and a right diagonal line of a half-pixel unit based on surrounding pixels of the quarter pixel; and an interpolation processor for interpolating a pixel value for the quarter pixel by differently applying a linear interpolation method depending on the directivity determined by the directivity determiner.
