Method and apparatus for adjusting exposure in digital imaging
Abstract:
The invention relates to electronic equipment for performing imaging, including a camera (CAM) for forming image frames (FRp, FRc), using set exposure parameters (ET, AG, DG), and a unit for determining the total exposure level (EV), from at least some of the image frames, and a unit for adjusting the said exposure parameters on the basis of the determined total exposure level of the exposure. In addition, the equipment also includes a motion-detection for detecting movement from at least some of the image frames. In the equipment the exposure parameters are arranged to be adjusted on the basis of the said total exposure level of the exposure and the detected movement.
