An automated light control system for controlling light emission from the backlight of the liquid crystal display in such a manner that the power consumption can be reduced, taking the information on the brightness in the peripheral region and the information on the distance into total consideration, is provided. The automated light control system is characterized in that a brightness information detecting means for detecting the brightness in the periphery and outputting information on the brightness for indicating the brightness and a distance information detecting means for outputting information on the distance for indicating the distance between the liquid crystal display and the user are provided, and the amount of light emitted by the light illumination means (backlight) is controlled on the basis of both the above described information on the brightness and the above described information on the distance. |
