SYSTEM AND METHOD FOR CAPTURING DIGITAL IMAGES USING MULTIPLE SHORT EXPOSURES
First Claim
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 second image with a second exposure length during the capturing of the first image; and
combining the first image and the second image to form a high dynamic range image.

Abstract
Methods, devices, and computer program products for image sensors with overlapped exposure brackets supporting multiple short exposures are described. In one aspect, a method of capturing an image is disclosed. The method includes capturing, on a first subset of pixels on an image sensor, a first image with a first exposure length. The method further includes simultaneously capturing, on a second subset of pixels on an image sensor, a plurality of images with a second exposure length, wherein the second exposure length is shorter than the first exposure length. The method further includes combining the plurality of images with a second exposure length into a second image. Finally, the method includes combining the first image and the second image.
