Described herein is a rearview mirror (100) for a vehicle (102). The rearview mirror (100) comprises a body (104) mounted to the vehicle (102) and supporting an electrically controllable reflective device (108). A camera (110) is mounted to or adjacent to the body (104). The camera (110) comprises an image sensor having a pixel array adapted to capture two or three dimensional images of an interior of the vehicle (102), including a rear window (112), in both the visible and infrared wavelength range. A processor (124) is configured to process the captured images to generate a control signal for controlling a transmittance of the electrically controllable reflective device (108). The control signal is derived based on a comparison of pixel brightness between pixels within an interior vehicle cabin pixel region (150) and a rear window pixel region (152) in the captured images.
