Claim One:
1. A method for providing a digital copy of a source image, comprising the steps of: averaging multiple samples of the source image for generating the digital copy, the averaging step comprising: performing a statistical comparison of at least two of the multiple samples within the source image to detect for misalignment between the multiple samples, and compensating for detected misalignment, wherein the performing the statistical comparison comprises: defining a reference area in a first one of the samples, allocating a reference pixel position on the sample to the reference area, locating a similar area having the same size as the reference area within a predetermined surrounding of a respective pixel position in at least one other sample, which respective pixel position corresponds to the reference pixel position, allocating a pixel position on the at least one other sample to the similar area, comparing the pixel position of the reference area with the allocated pixel position of the similar area for detecting the misalignment between the reference area and the similar area, wherein the statistical comparison is performed by using a cost function to find minima.
