167results about How to "Strong light" patented technology

An improved camera for the acquisition of panoramic images is disclosed. The camera comprises a convex photochromic reflector directed towards an image capture element. Multiple incoming light sensors around the perimeter of the camera detect strong incoming light and cause the activation of a corresponding UV light. The UV light in turn activates the photochromic effect on a particular region of the photochromic reflector that corresponds to an area of strong incident light. The photochromic reflector then darkens in that area, providing compensation for a scene that has a wide range of lighting conditions. Therefore, the camera compensates for strong lighting indoors as well as outdoors.

The illuminance of a light source is controlled so that intensity of illumination becomes the determined illuminance. A face authentication terminal then authenticates the person to be authenticated under illumination by the illumination unit.
