Dynamic Rearview Mirror Adaptive Dimming Overlay Through Scene Brightness Estimation

A method for dynamically adjusting a brightness of an image on rearview display device, the method comprising the steps of:

• capturing an image exterior of a vehicle by an image capture device, the captured image including at least a portion of a sky scene;
• generating a virtual image of a virtual sky scene a processor from the portion of the sky scene captured by the image capture device, the processor determining a brightness of the virtual sky scene from the virtual image, the processor dynamically adjusting a brightness of the captured image based the determined brightness of the virtual image;
• and
• displaying the adjusted captured image on a rear view mirror display device for displaying the adjusted captured image.
