<p>A digital camera control system that requires no light sensors is described. The control system relies on modeled external environmental geophysical solar parameters, geometric relationships between the object to be imaged and surrounding potentially shadowing objects and the material properties of the object to be imaged such as reflectivity are combined to produce the estimated irradiance on a camera sensor for the particular time of day, date and geometric relationship between the object and the sun. The system enables setting optimized camera settings with no external or internal light sensors. The system therefore provides a method to rapidly determine an optimum camera settings for any time of day and ensures the camera is always ready to capture a high contrast image of a fast moving transient object. The system is demonstrated for use in a license plate imaging application.</p> |
