First Claim
1. A monitoring assembly for use in a vehicle, comprising:
- a monitor device changing the reflectance thereof in response to a control signal;
a first light sensor for receiving a first light from a first specified range, and outputting a first signal in response to the intensity of said first light;
a second light sensor for receiving a second light from a second specified range partially overlapping with said first specified range, and outputting a second signal in response to the intensity of said second light; and
a comparative controller in communication with said first and said second light sensors, receiving and operating said first and said second signals to obtain a first result, and asserting said control signal to adjust the reflectance of said monitor device according to said first result.

Abstract
An anti-glare rearview mirror assembly and a reflectance control method thereof are disclosed. The assembly includes an electrochromic rearview mirrors, two rearward light sensors, and a comparative controller. The sensors receiving a first rearward light from a first specified region and a second rearward light from a second specified region at the same time point, respectively, wherein the first and second specified regions partially overlap with each other. The intensities of the first and second rearview mirror light are compared to obtain a light difference. The reflectance of the anti-glare rearview mirror is adjusted according to the light difference.
