Zusammenfassung:A system for creating an image with a wide dynamic range includes an imaging unit, a processing unit and a control unit operatively connected to each other. The imaging unit is configured to acquire a plurality of images of a scene at respective exposure times such that each of the respective exposure times are different from one another. The images are each represented by a set of pixels, each defining a respective pixel intensity. The processing unit is configured to combine the plurality of images to produce a combined image based at least in part on weighting factors assigned to each pixel and a mapping graph.
