A system for variable transmittance mirrors is disclosed wherein the variable transmittance mirrors may be controlled in response to images captured from a camera. The system may comprise a first imager, a first variable transmittance mirror, and a controller. The first imager comprises a pixel array. Further, the first imager is configured to capture image data. The first variable transmittance mirror has a first level of transmittance. Finally, the controller is configured to assign a first light intensity value to one or more pixels and change the first level of transmittance to a second level of transmittance based at least in part on the detected first light intensity. Such as system has the advantage of eliminating the need for a dedicated glare sensor, therefore reducing the number of devices, the costs, obstructions in a user's field of view, and a more aesthetically appealing appearance.
