Abstract

PURPOSE: To adjust a color temperature of a screen to a most suitable temperature even when the state of a surrounding light of a video display device is changed.
CONSTITUTION: A semiconductor color sensor 12 detecting a color temperature of an external light is provided to a video display equipment displaying a video image in color onto a display device 7 while controlling a color temperature on the screen, for example, a video control circuit of a color television receiver and a color temperature displayed onto the screen of the display device 7 is changed over and controlled in response to the result of color detection of the color sensor 12. For example, a level of each of R, G, B color signals is switched by a microcomputer or the like and a video image with an optimum color temperature in matching with the color temperature of surrounding light is displayed on the screen of the display device 7. Furthermore, the relation between the color temperature of the external light and the color temperature on the screen of the display device 7 to be set is changed optionally by an external operation means 15.
