1. A vehicular rearview mirror control system, the vehicular rearview mirror control system comprising:
a driver-side exterior rearview mirror assembly configured to attach at a driver side door of a vehicle equipped with the vehicular rearview mirror control system, the driver-side exterior rearview mirror assembly comprising a driver-side exterior variable reflectance mirror reflective element;
a driver-side door module unit (DMU) disposed at the equipped vehicle;
a rear backup camera disposed at the equipped vehicle, the rear backup camera viewing at least rearward of the equipped vehicle, wherein the rear backup camera is operable to capture frames of image data;
wherein the vehicular rearview mirror control system, via processing of a first subset of image data captured by the rear backup camera, determines ambient light rearward of the equipped vehicle;
wherein the vehicular rearview mirror control system, via processing of a second subset of the image data captured by the rear backup camera, determines glare light emanating from a headlight of another vehicle following the equipped vehicle;
wherein the first subset of the image data captured by the rear backup camera is different than the second subset of the image data captured by the rear backup camera; and
wherein, with the driver-side exterior rearview mirror assembly attached at the driver side door of the equipped vehicle, and based at least in part on determined glare light, the driver-side DMU controls dimming of the driver-side exterior variable reflectance mirror reflective element of the driver-side exterior rearview mirror assembly.
