Abstract
A method and electronic information handling system provide recording a first image of a scene at a first exposure level using a three-dimensional (3D) camera, correlating distances from the 3D camera and exposure levels over a plurality of image elements of the first image, selecting an exposure parameter value for at least one of the plurality of image elements having a z-distance value falling within a range of z-distance values, recording a second image of the scene according to the exposure parameter value, and constructing a composite image based on at least a portion of the second image for the at least one of the plurality of image elements.
