Luminance control of automotive displays using an ambient light sensor |
摘要 |
According to the system and the method of the present invention, a display's visibility is maintained depending on lighting conditions that are sensed by an ambient light sensor (16). Logic (10) is applied to the output of the light sensor (16) and in conjunction with a headlight status indicator (14) to determine whether daytime (D) or nighttime (N) lighting condition exists and to determine a brightness level (18) to be commanded to the display. The logic (10) of the present invention maintains a visible display even in situations where a vehicle's headlights are active during daylight lighting conditions. |
