Abstract
A light-responsive control device of an electrochromic rearview mirror system is disclosed. The light-responsive control device includes a discriminating circuit for generating a first and a second reference levels provided for daytime and nighttime glaring determination, respectively. By providing a photo-sensor for each rearview mirror, and individually comparing the outputs of the photo-sensors with the first or the second reference level, the color-change degrees of different rearview mirrors can be individually controlled. By providing a variable resistor for the drive circuit, the initial reflection rate of the rearview mirror can be adjusted optionally.
