Target dot sight having target illumination sensor

Abstract

A target dot sight includes a target illumination sensor that senses the amount of illumination at a target, rather than merely sensing the ambient sight of the entire operating environment. Then, based on the sensed target illumination, the target dot sight may automatically compensate for the brightness of the target.

What is claimed is: 
     
         1 . A targeting sight, comprising:
 a light generating source structured to generate a target light and project it toward a target;   a target light sensor disposed in the targeting sight and structured to sense a brightness value of the target while excluding ambient light from the target light sensing;   a storage component structured to store a light value; and   a brightness controller structured to control the light generating source based at least in part on the brightness value sensed by the target light sensor.
