<p>Blur is reduced in an image generated by an imaging device by determining values of one or more atmospheric variables for the image, the one or more atmospheric variables characterizing conditions under which the image is generated. With these values, a sharpening filter is determined for the image. The sharpening filter is derived from a modulation transfer function of the imaging device at conditions characterized by the values of the one or more atmospheric variables determined for the image. The sharpening filter is subsequently applied to the image.</p> |
