Feedback system for optimizing exposure

Abstract

A processor disposed inside of a display device analyzes the image received by a camera mounted on the display device to determine the optimum output intensity of a light source also mounted on the display device.

1 . System comprising:
 a video display;   a light source associated with the display for projecting light onto a user of the display who is facing the display;   a camera positioned to image a user facing the display; and   a processor receiving signals from the camera and responsive thereto establishing an output of the light source.   
     
     
         2 . The system of  claim 1 , wherein the processor controls the display. 
     
     
         3 . The system of  claim 1 , wherein the camera is mounted on the display. 
     
     
         4 . The system of  claim 1 , wherein the light source is mounted on an edge of the display. 
     
     
         5 . The system of  claim 1 , wherein the light source is disposed inside a bezel of the display. 
     
     
         6 . The system of  claim 1 , wherein the processor uses colorimetry information from the camera to establish the output of the light source. 
     
     
         7 . The system of  claim 1 , wherein the output of the light source established by the processor is brightness. 
     
     
         8 . The system of  claim 1 , wherein the output of the light source established by the processor is color temperature. 
     
     
         9 . Method comprising:
 imaging a user of a video display associated with a light source illuminating the user; and   based on the imaging act, establishing an indicia of illumination of the light source to achieve a desired illumination of the user.   
     
     
         10 . The method of  claim 9 , wherein the indicia is brightness. 
     
     
         11 . The method of  claim 9 , wherein the indicia is color temperature. 
     
     
         12 . The method of  claim 9 , wherein a processor controls the display. 
     
     
         13 . The method of  claim 9 , wherein a camera is mounted on the display to facilitate the imaging act. 
     
     
         14 . The method of  claim 9 , wherein the light source is mounted on an edge of the display. 
     
     
         15 . The method of  claim 9 , wherein the light source is disposed inside a bezel of the display. 
     
     
         16 . The method of  claim 12 , wherein the processor uses colorimetry information from a camera to establish the output of the light source. 
     
     
         17 . System comprising:
 a video display;   a light source projecting light onto a user of the display who is facing the display;   an imager positioned to image a user facing the display; and   a processor receiving signals from the imager and responsive thereto establishing an output hue, and/or a brightness, of the light source.   
     
     
         18 . The system of  claim 17 , wherein the imager is mounted on the display. 
     
     
         19 . The system of  claim 17 , wherein the light source is mounted on an edge of the display. 
     
     
         20 . The system of  claim 17 , wherein the light source is disposed inside a bezel of the display.
