ABSTRACT:
Deblurring of digital camera images by estimating the blur function from an image extracted from a video sequence taken about the time of an image capture. The extracted image is selected to be the sharpest of the images of the video sequence, and comparison of this sharpest image with the (down-sampled) captured image provides blur function iterative estimation.
