Abstract
A frame interpolation method generates an interpolated frame that is temporally between a first frame and a second frame. A first and a second interpolated frames are generated using motion vectors from a first motion estimator and a second motion estimator, respectively. A weighting map is generated based on indications from the first motion estimator. First pixel locations and second pixel locations in the weighting map are assigned weight values of 1 and 0, respectively. A weighted combination is calculated using the weighting map to produce the interpolated frame output, which includes the first pixel locations from the first interpolated frame and the second pixel locations from the second interpolated frame. The first and the second motion estimators may be an optical flow estimator and the game engine renderer, respectively. Alternatively, the first and the second motion estimators may be the game engine renderer and the optical flow estimator, respectively.
