Abstract
A method of capturing an image of a scene using an image capture device having an array of pixels, wherein the array of pixels includes pixels of different colors, includes, for a first duration, capturing a first portion of the scene with a first plurality of the pixels of a first color, and for a second duration, capturing a second portion of the scene with a second plurality of the pixels of a second color. The first and second durations are different and the first and second durations are chosen, at least in part, to improve the signal to noise ratio of the image capture device.
