Abstract
A method for determining a deblurred image, the method implemented at least in part by a data processing system and comprising: receiving a sharp image of a scene captured with a short exposure time; receiving a blurred image of the scene captured with a longer exposure time than the sharp image, wherein the blurred image has a higher level of motion blur and a lower level of image noise than the sharp image; determining a blur kernel responsive to the sharp image and the blurred image; determining one or more reference differential images responsive to the sharp image; determining a deblurred image responsive to the blurred image, the blur kernel and the one or more reference differential images; and storing the deblurred image in a processor-accessible memory system.
