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.
Claims7
An electronic imaging device, comprising:
- a photodetector;
- a fisheye lens;
- and
- an image processing system, said image processing system comprising instructions for electronically filtering an image captured by said photodetector to remove a fisheye effect caused by said fisheye lens, wherein a filtered image has a higher resolution than said image, said electronic imaging device having a portrait mode and landscape mode, so that a long axis of said photodetector is oriented vertically in said portrait mode and a short axis of said photodetector is oriented vertically in said landscape mode, and wherein said fisheye lens is centered on said long axis and above said short axis when said electronic imaging device is in said portrait mode.
