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.
