1. A method of capturing a high dynamic range image, comprising: capturing, on a first subset of pixels on an image sensor, a first image with a first exposure length; capturing, on a second subset of pixels on the image sensor, a plurality of images with a second exposure length, wherein the second exposure length is shorter than the first exposure length; combining the plurality of images with a second exposure length into a second image; and combining the first image and the second image to form a high dynamic range image.
