INTERPOLATION METHOD AND PREDICTION METHOD USING SAME

摘要

The present invention relates to a method of performing interpolation for prediction between screens by using a pixel sample of a current picture and a pixel sample of a reference picture, and a prediction method using same. The interpolation method according to the present invention includes: calculating movement information for generating a prediction block; and generating a partial pixel sample on the basis of an integer sample set including integer pixel samples to which an interpolation filter is applied. Here, the integer sample set includes at least one current integer sample used to generate a partial pixel sample among restored integer pixel samples of a current picture, and the partial pixel sample corresponds to the offset positions of a partial pixel unit from a predetermined reference pixel sample among integer pixel samples.
