Camera and method with widescreen image on nearly-square aspect ratio photosensor array

Abstract

A digital widescreen camera has an anamorphic lens focusing a field of view nearly twice as wide as tall on a photosensor array having nearly square aspect ratio. In embodiments, the photosensor array has an 8-pixel tiling unit organized as four pairs of adjacent left and right pixels, a first pair having two red-responsive pixels, a second pair having two blue-responsive pixels, and a third pair having two green-responsive pixels. In embodiments, signals from the 8-pixel tiling unit are processed into signals equivalent to signals from two adjacent Bayer-pattern 4-pixel tiling units. The corresponding method of digital photography includes receiving light through an anamorphic lens onto a photosensor array. In embodiments, the photosensor array has an eight-pixel tiling with four pairs of adjacent left and right pixels, a first pair with two red-responsive pixels, a second pair with two blue-responsive pixels, and a third pair with two green-responsive pixels.
