Claim One:
1. A system for creating an image with a wide dynamic range, the system comprising: an imaging unit 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; a processing unit and a control unit operatively connected to the imaging unit and to each other; wherein the plurality of images are each represented by respective sets of pixels defining respective pixel intensities, each pixel in the respective sets of pixels being identifiable by a two-dimensional coordinate; wherein the processing unit is configured to combine the plurality of images to produce a combined image represented by a set of combined pixels; wherein for each of the two-dimensional coordinates the processing unit is configured to: receive the respective pixel intensities for each of the plurality of images from the imaging unit; assign a respective weighting factor to the respective sets of pixels in each of the plurality of images; obtain a respective combined intensity value for the set of combined pixels at each of the two-dimensional coordinates; convert the respective combined intensity values into respective mapped values using a mapping graph, the respective mapped values being used to generate the combined image.
