Patent attributes
A vehicular exterior rearview mirror control system is configured to attach at a side of a vehicle and includes a mirror assembly having a variable reflectance mirror reflective element. The vehicular rearview mirror control system processes image data captured by a rear backup camera of the vehicle. The rearview mirror control system, via processing a first subset of image data captured by the rear backup camera, determines ambient light rearward of the vehicle. The rearview mirror control system, via processing a second subset of received image data captured by the rear backup camera, determines glare light emanating from a headlight of another vehicle following the equipped vehicle. The first subset of captured image data is different than the second subset of captured image data. A door module unit of the vehicle controls dimming of the variable reflectance mirror reflective element based at least in part on the determined glare light.
