Abstract:

At least a method and a system are described for providing frame rate upconversion by way of using “short side” or bidirectional interpolation in generating interpolated frames. In a representative embodiment, the method may comprise receiving a first frame of video corresponding to a first frame time and a second frame of the video corresponding to a second frame time, computing a first absolute difference between the first frame time and an interpolated frame time wherein the interpolated frame time temporally is located between the first frame time and the second frame time. The method further comprises using a first motion vector field and the first frame to compute a third frame at the interpolated frame time. The method further comprises outputting the third frame as the interpolated frame at the interpolated frame time if the first absolute difference is less than or equal to a first threshold value.
