Abstract
Motion sensor data may be used to register a sequence of standard dynamic range images for producing a high dynamic range (HDR) image, reducing use of computational resources over software visual feature mapping techniques. A rotational motion sensor may produce information about orientation changes in the imaging device between images in the sequence of images sufficient to allow registration of the images, instead of using registration based on analysis of visual features of the images. If the imaging device has been moved laterally, then the motion sensor data may not be useful and visual feature mapping techniques may be employed to produce the HDR image.
