Abstract
An apparatus for generating a reference frame is disclosed including: an interpolation unit for interpolating a reference frame per fractional pixel; a virtual encoder for determining a block mode of a current frame and a motion vector according to the block mode by using an interpolated reference frame; an offset calculator for calculating an offset for each pixel of the interpolated reference frame by using the block mode and the motion vector; and an offset adder for generating an offset interpolated reference frame by adding the offset for each pixel to each pixel of the interpolated reference frame. By adding the offset calculated according to the block mode to the reference frame for the inter prediction and making the reference frame to be used for the motion estimation and compensation similar to the current frame to be encoded, motion prediction is accurate and compression efficiency is improved.
