    摘要: A method for creating an interpolated video frame using a current video frame, and a plurality of previous video frames. The method includes creating a set of extrapolated motion vectors from at least one reference video frame in the plurality of previous video frames; performing an adaptive motion estimation using the extrapolated motion vectors and a content type of each extrapolated motion vector; deciding on a motion compensated interpolation mode; and, creating a set of motion compensated motion vectors based on the motion compensated interpolation mode decision. An apparatus for performing the method is also disclosed.
