A vehicular frameless interior rearview mirror assembly includes a mirror head and a mounting portion. The mirror head includes a mirror reflective element and a mirror casing. The mirror reflective element includes a glass substrate having a planar front side and a planar rear side. No portion of the mirror casing overlaps the planar front side of the glass substrate of the mirror reflective element. A camera is disposed within the mirror casing. With the mounting portion of the mirror assembly mounted at an in-cabin side of a windshield of a vehicle, the camera views a driver of the vehicle, and when the mirror head is moved by the driver of the vehicle to adjust the rearward view provided by the mirror reflective element to the driver, the camera moves in tandem with movement of the mirror head. The camera is part of a driver monitoring system of the vehicle.

A multifunctional rear camera system includes a rear camera and a processor. Responsive to processing of captured image data, the processor generates respective outputs for (i) a rear backup assist function, (ii) a mirror dimming control for at least an electro-optic interior rearview mirror assembly of the vehicle and (iii) ambient light detection. The processor processes a mirror zone of captured image data for mirror dimming control and processes upper corner regions of captured image data for ambient light detection. The processor processes at least lower regions of captured image data for the rear backup assist function. The generated output for the mirror dimming control is provided to the electro-optic interior rearview mirror assembly to control dimming of the electro-optic reflective element. The generated output for the rear backup assist function provides (i) object detection and/or (ii) video display of video images derived from captured image data.
