ABSTRACT:
A display (4) has its representation made by brightness of a backlight (7). A left flasher (SW 1) and a lighting (SW 3) supply on/off information to a dimming judgement unit (9). The dimming judgement unit (9) determines that when the lighting (SW 3) is turned on the environment is dark, and detects that a vehicle is going to make a left turn when the left flasher (SW 1) is turned on. It is further assumed according to the left turn of the vehicle that the driver's line of sight is turned to the left, and luminance of the backlight (7) is lowered. It is thus possible to prevent driver annoyance with a bright display (4), even when the display (4) comes within the driver's line of sight.
