Claim One:
1. An image processing method to process a first relatively underexposed and sharp image of a scene, and a second relatively well exposed and blurred image nominally of the same scene, said method comprising: providing a portion of said first relatively underexposed image as an input signal to an adaptive filter; providing a corresponding portion of said second relatively well exposed image as a desired signal to said adaptive filter; producing an output signal from said input signal and said desired signal by multiplying the input signal by one or more coefficients that are calculated from values of the input signal and the desired signal; constructing a first filtered image, from said output signal, that is relatively less blurred than said second image; and displaying, transmitting, projecting or storing the first filtered image or a further processed version, or combinations thereof; wherein the method is performed by one or more computing devices.
