Abstract
A wide-angle lens produces a distorted wide-angle optical image. An imaging sensor, having a surface in optical communication with the wide-angle lens, converts the wide-angle optical image into a corresponding output signal. The imaging sensor includes a plurality of imaging elements. The plurality of imaging elements have a distribution on the surface of the sensor that is representable by a nonlinear function, wherein the distribution of the imaging elements corrects the distortion in the wide-angle image.
Claims20
An electronic imaging system for capturing a wide-angle image, the system comprising;
- a wide-angle lens for producing a wide-angle optical image, the wide-angle lens producing a distortion in the wide-angle image;
- and
- an imaging sensor, having a surface in optical communication with the wide-angle lens, for converting the wide-angle optical image into a corresponding output signal, the imaging sensor comprising a plurality of imaging elements, the plurality of imaging elements having a distribution on the surface representable by a nonlinear function;
- wherein the distribution of the imaging elements corrects the distortion in the wide-angle image.
A sensor use in an electronic imaging system having a wide-angle lens that produces a wide-angle optical image having a distortion, the sensor comprising;
- a surface in optical communication with the wide-angle lens;
- and
- a plurality of imaging elements, coupled to the surface, for converting the wide-angle optical image into a corresponding output signal, the plurality of imaging elements having a distribution on the surface representable by a nonlinear function;
- wherein the distribution of the imaging elements corrects the distortion in the wide-angle image.
