1. A method of correcting blur in a motion blurred image using an estimate of motion blur direction and motion blur extent based on the motion blurred image, the method comprising:

  • generating an initial guess image based on said motion blurred image;

    blurring the guess image as a function of said estimated blur direction and blur extent;

    comparing the blurred guess image with the motion blurred image to generate an error image;

    blurring and weighting the error image; and

    combining the error image and the initial guess image thereby to update the guess image and correct for blur.
