Abstract
A frame buffer is adapted to store at least one reference frame of a video stream, said reference frame being different from a current frame of the video stream. A motion estimation unit is adapted to generate a motion vector by estimating motion between a reference block of the reference frame and a current block of the current frame. A blurring filter selection unit is adapted to select one of a plurality of blurring filters depending on the orientation of the motion vector. A filtering unit is adapted to generate a filtered reference block by applying the selected blurring filter to the reference block. A motion compensation unit is adapted to generate a filtered prediction block of the current block on the basis of the current block, the motion vector and the filtered reference block.
