1. A method of processing data for an image frame, the method comprising:

  • receiving a plurality of input frames including a current frame;

    providing the current frame to a first multiplier, to a frame averaging module, and to a first low pass filter;

    after the current frame is provided to a first low pass filter, detecting at least a portion of the current frame that includes motion;

    generating a mask frame associated with the portion of the current frame that includes the motion detection;

    providing the mask frame to a second low pass filter;

    after the current frame is provided to the frame averaging module, averaging the current frame and one or more stored frames to generate an averaged current frame;

    providing the averaged current frame to a second multiplier; and

    generating an output frame based at least in part on the averaged current frame and the current frame after the first multiplier.
