1. A method for determining a deblurred image, the method implemented at least in part by a data processing system and comprising:

  • a) receiving a blurred image of a scene;

    b) receiving a blur kernel;

    c) initializing a candidate deblurred image;

    d) determining a plurality of differential images representing differences between neighboring pixels in the candidate deblurred image;

    e) determining a combined differential image by combining the differential images;

    f) updating the candidate deblurred image responsive to the blurred image, the blur kernel, the candidate deblurred image and the combined differential image;

    g) repeating steps d)-f) until a convergence criterion is satisfied; and

    h) storing the final candidate deblurred image in a processor-accessible memory system.
