Abstract
A method for determining a deblurred image comprising: receiving a blurred image of a scene; receiving a blur kernel; initializing a candidate deblurred image; determining a plurality of differential images representing differences between neighboring pixels in the candidate deblurred image; determining a combined differential image by combining the differential images; repeatedly updating the candidate deblurred image responsive to the blurred image, the blur kernel, the candidate deblurred image and the combined differential image until a convergence criterion is satisfied; and storing the final candidate deblurred image in a processor-accessible memory system.
