Patent ID: 8368803

Claim:
A method, comprising: capturing a projection of a preview image on a surface with a capturing device; receiving input identifying one or more regions of interest in the captured preview image; projecting an exposure image onto the surface, wherein the exposure image is related to a calibration process and contains at least one of a red, green or blue color; computing a configuration of exposure attributes for the capture device by iteratively (a) capturing the projection of the exposure image with the capture device using a configuration of exposure attributes, (b) measuring one or more descriptive statistics relating to pixels in regions of interest in the capture of the exposure image that correspond to the identified regions of interest in the capture of the preview image; (c) evaluating the one or more descriptive statistics with an evaluation function determined by the calibration process, and (d) establishing a revised configuration of exposure attributes for the capture device; and storing exposure settings based on the configuration of exposure attributes, wherein each operation of the method is executed by a processor.
