ABSTRACT:
A display device includes an ambient light sensor positioned adjacent a display screen so as to confront an occupant in front of the display device, and a luminance level setting unit for inputting a desired luminance level. An output from the ambient light sensor is fed to a screen luminance calculating unit for calculating the adjustable range of screen luminance to be adjusted on the basis of an output signal from the ambient light sensor. A luminance determining unit determines a proper screen luminance based on an output signal from the screen luminance calculating unit and an output signal from the luminance level setting unit. A screen luminance control unit operates in response to an output signal from the luminance determining unit to adjust the screen luminance to the proper screen luminance.
