Abstract
An improved system and method for capturing an image using a camera or a camera module. In the present invention, the number of image shots taken, as well as the integration time of each image shot, are controlled based upon knowledge about the existence or absence of camera motion. Whenever a motion is detected above a predetermined motion threshold, the integration phase of the current image shot ends, and the integration of the next image shot begins. The present invention therefore adapts to the actual camera motion during exposure. If there is no camera motion, a single, long exposed image shot is captured. If there is camera motion, the total exposure time is divided between multiple shots in accordance with the degree of camera motion.
