How does the Macbook check the ambient light to determine the screen brightness, does it have a separate ambient light detector buried under the screen somewhere or inside the camera? (if the camera is not used for this I mean which would have been the best thing to do, but would require the camera to grab frames now and then without the LED flashing)
