Method and system for noise reduction in video systems

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 frame multiplexor, 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;
• calculating a motion value associated with the mask frame;
• comparing the motion value with a threshold;
• averaging the current frame and one or more stored frames to generate an averaged current frame;
• providing the averaged current frame to the frame multiplexor;
• and
• generating an output frame based at least in part on the averaged current frame and the current frame after the first multiplexor.
