Abstract
In a method for estimating a point spread function of an image capture device, a first function representing a captured version of a first test image is obtained, where the first test image containing a substantially ideal vertical transition. A second function representing a captured version of a second test image is also obtained, where the second test image contains a substantially ideal horizontal transition. In addition, the point spread function is estimated from the first function and the second function. Also disclosed herein is a method for image degradation compensation that employs the method for estimating a point spread function.
