Abstract
A method of enhancing resolution in an electronic imaging device includes capturing an electronic image through a fisheye lens with a photodetector at a resolution native to the photodetector. A resolution is selected that is higher than the native resolution of the photodetector. The electronic image is processed to produce a new electronic image at the higher resolution. A fisheye effect caused by the fisheye lens is removed during processing.
