Claims20
A method for improving an optical image provided by a lens system as used with a camera comprising passing a compressed optical image produced by at least one anamorphic element of the lens system to at least one corrective lens element, wherein the at least one corrective element is configured to improve an optical quality of the compressed optical image on a digital image sensor of the camera.
A lens group comprising:
- at least one anamorphic lens element configured to produce a compressed optical image;
- and
- at least one corrective lens group configured to improve an optical quality of the compressed optical image on a digital image sensor of a camera used with the lens group.
A combination of lens elements for improving a quality of an optical image for digital image capture comprising:
- at least one anamorphic lens element configured to compress an optical image;
- at least one corrective lens element configured to receive the compressed optical image and improve a quality of the compressed optical image on a digital image sensor used for digital image capture.
