PROBLEM TO BE SOLVED: To provide a method, a system and an article that provide robust automatic exposure control using embedded data.SOLUTION: A method comprises: receiving embedded exposure parameter data used to capture image data for a plurality of frames and embedded in a data stream with image data; obtaining convergence plan data comprising a plurality of target exposure parameter values forming at least part of an exposure convergence plan, where the convergence plan data provides data to form a targeted variation of brightness along a sequence of the frames; determining an extra digital gain calculated by using both the embedded exposure parameter data for a frame of the sequence of the frames, and a corresponding target exposure parameter of the exposure convergence plan; and providing the extra digital gain for image processing to display, store, and/or encode the frame of the sequence of frames. |
