1. A method for reducing motion artifacts in an output image, comprising:

  • capturing multiple frames of a scene;

    determining local motion vectors between each pixel in a current frame and a corresponding pixel in a previous frame; and

    performing a selective temporal filtering operation based on the local motion vectors to form the output image;

    wherein said temporal filtering operation (a) rejects a local motion vector if the local motion vector is above a threshold in which case no temporal filtering is performed;

    (b) averages a current pixel with the corresponding pixel from the previous frame if the local motion vector for the current pixel is considered zero; and

    (c) averages the current pixel with the motion-compensated pixel from the previous frame in all other cases.
