Systems and methods of motion compensated frame rate conversion are described herein. These systems and methods convert an input video sequence at a first frame rate to an output video sequence at a second frame rate through a novel motion estimation and motion vector processing stage that produces a motion field having a plurality of motion vectors that describe the movement of objects between input video frames from the perspective of an interpolated video frame. A subsequent motion compensated interpolation stage then constructs the interpolated video frame using an adaptively blended combination of a motion compensated prediction and a temporal average prediction of the pixel values from the input video frames. Motion estimation in these systems and methods is enhanced by utilizing spatial and temporal biasing on the predictions of moving objects between and within the input frames, and also by removing aberrational motion vectors from the motion field through a hierarchy of motion vector processing blocks.
