  • Patent number: 11403979
    Abstract: Implementations disclosed herein provide improved systems and methods for displaying video that has at least some content in the same position in consecutive frames. In some implementations, such content is low frame rate video content altered for display on a display at a higher refresh rate. Judder is reduced or avoided by selectively altering one or more of the consecutive frames, for example, so that the consecutive frames have differences in brightness, color, luminance, or dynamic range. For example, given three consecutive frames of repeated content, the first frame of may be displayed at a 100% brightness level, the second frame may be displayed at 50% brightness, and the third frame may be displayed at 25% brightness. Such differences in brightness or other display characteristics may reduce or avoid the appearance of judder while preserving the overall appearance of the video.
