1. A method for deblurring a captured image taken by an imaging device comprising an imaging sensor array for capturing the image during an exposure time and at least one motion sensor, the method comprising the steps of:

  • [a] obtaining the captured image;

    [b] obtaining a set of motion parameters from the motion sensor related to the motion of the imaging sensor array during the exposure time and wherein at least one of the motion parameters within the set of motion parameters possesses associated interval values such that a family of motion paths may be defined by the set of motion parameters and associated interval values;

    [c] obtaining an estimated point spread function that comprises the convolution of an optical point spread function of the imaging device and a motion path selected from the family of motion paths defined by the set of motion parameters and associated interval values;

    [d] selecting an estimated deblurred image;

    [e] computing a new estimated point spread function based upon the captured image, the estimated deblurred image, and the estimated point spread function;

    [f] performing an optimization over the set of motion parameters and associated interval values to find a set of optimized parameter values within the set of motion parameters and associated interval values that yield an optimized point spread function that best fits the new estimated point spread function; and

    [g] using the optimized point spread function to compute a new estimated deblurred image.
