A digital camera comprising a digital image sensor and at least one corrective lens element configured to reduce a blurring of an image in a horizontal or vertical dimension on the digital image sensor. Preferably the digital image sensor is a large digital imager such as a Digital 65 imager.
Claims21
1-20. (canceled)
A lens system for use with a camera, comprising:
- a first lens element configured to receive an image and compress the image in a horizontal or vertical dimension to produce an image having a reduced aspect ratio;
- and
- a second lens element configured to improve a quality of the image produced by the first lens group in the dimension of compression, wherein the second lens element is aligned along an optical axis of the first lens element.
A lens system for use with a camera, comprising:
- an anamorphic lens element configured to receive an image and compress the image in a horizontal or vertical direction by a squeeze ratio of at least 1.19;
- and
- a corrective lens element that is configured to improve an optical quality of the image produced by the anamorphic lens element in the direction of compression as processed by a digital image sensor positioned to receive an image from the corrective lens element.
A method for improving an optical quality of an image produced by a lens system comprising:
- passing an optical image into a first lens element that is configured to compress the image in a horizontal or vertical dimension and produce an image having a reduced aspect ratio;
- and
- treating the compressed image by passing the compressed image through a second lens element, wherein the second lens element is configured to improve an optical quality of the compressed image.
