Abstract
Systems and methods are disclosed for generating long exposure images for high dynamic range processing. For example, methods may include receiving a short exposure image that was captured using an image sensor; receiving an additional image that was captured using the image sensor; determining a long exposure image based on the short exposure image and the additional image; applying high dynamic range processing to the short exposure image and the long exposure image to obtain an output image with a larger dynamic range than the short exposure image; and transmitting, storing, or displaying an image based on the output image.
