1. A method of scanning an image, the method comprising the steps of: performing a first scan of the image to produce a first representation of the image; performing a second scan of the image to produce a second representation of the image, a motion error having been intentionally induced between the first and second representations; and using a super resolution technique to generate a third representation of the image from the first and second representations of the image, the third representation having a higher resolution than the first and second representations.
