Abstract
High dynamic range image composition is described using multiple images. Some embodiments relate to a system with a buffer to receive each of three different images of a scene, each image having a different amount of light exposure to the scene, as general purpose processor to estimate the alignment between the three images, and an imaging processor to warp the images based on the estimated alignment and to combine the three images to produce a single high dynamic range image.
