Abstract

An apparatus and method of up-converting a frame rate using frames that are decoded from a video decoder and motion information, the apparatus including: a motion vector resampling unit to resample a motion vector for the interpolated frame by filtering a motion vector of a current block using the motion vector of the current block and motion vectors of adjacent blocks in the decoded frame; a motion compensating unit to compensate a motion of the decoded frame by the resampled motion vector to produce the interpolated frame; and a switch to selectively output one of the decoded frame and the interpolated frame according to the sequential order of the frames.
