First Claim
Patent Images
1. A method of enhancing resolution in an electronic imaging device, comprising:
- capturing an electronic image through a fisheye lens with a photodetector at a resolution native to said photodetector; and
selecting a resolution that is higher than said native resolution; and
processing said electronic image to produce a new electronic image at said higher resolution.

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.

9. 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. An electronic imaging device, comprising:
-
means for capturing an image, wherein a center region of said image is expanded and edge regions of said image are compressed; and
means for processing said image to expand said edge regions of said image to match said expanded center region, wherein a resolution of said image is increased by said processing.
