Abstract
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. The digital image sensor may be larger than a 28 millimeter diagonal.
Claims20
A digital camera system comprising:
- at least one anamorphic lens element configured to compress an image in a horizontal or vertical dimension;
- a digital image sensor configured to receive the image compressed by the at least one anamorphic lens element;
- and
- at least one corrective lens element including an anti-aliasing feature and configured to be positioned along an optical axis with the at least one anamorphic lens element and the digital image sensor, and configured to reduce a blurring of the image in the horizontal or vertical dimension on the digital image sensor caused by the digital image sensor to substantially equalize the image quality in the horizontal or vertical dimension.

A digital camera system comprising:
- a digital image sensor including an anti-aliasing filter;
- at least one anamorphic lens element configured to compress an image in a horizontal or vertical dimension;
- and
- at least one corrective lens element configured to be positioned along an optical axis between the at least one anamorphic lens element and the anti-aliasing filter, and configured to reduce a blurring of the image in the horizontal or vertical dimension on the digital image sensor caused by the digital image sensor to substantially equalize the image quality in the horizontal or vertical dimension.

A digital camera system comprising:
- at least one anamorphic lens element configured to compress an image in a horizontal or vertical dimension;
- a digital image sensor configured to receive the image compressed by the at least one anamorphic lens element;
- and
- a corrective lens element comprising one or more of a toroidal lens element or an anti-aliasing feature configured to be positioned along an optical axis between the at least one anamorphic lens element and the digital image sensor, wherein the corrective lens element is configured to reduce a blurring of the image in the horizontal or vertical dimension on the digital image sensor caused by the digital image sensor to substantially equalize the image quality in the horizontal or vertical dimension.
