A novel video system that detects events in a video sequence that causes such distortions and switch off optical flow based frame interpolation is provided. The system detects sudden changes in light intensity and switch to non-optical flow based frame interpolation when such sudden change is detected. When there is no such drastic change in light intensity, the system reverts back to using optical flow frame interpolation. Specifically, the system detects a flash event by computing a sum of differences in histograms of intensity levels between the pair of consecutive actual video frames. When the sum of differences is above a certain threshold, the video system switch to non-optical flow based frame interpolation. When the sum of differences is below the threshold, the video system reverts back to optical flow frame interpolation.
