Abstract
Calculating ambient light in a space by obtaining a top view image of the space from an array of pixels, and identifying an object in the image and assigning weights to pixels from the array of pixels based on locations of the pixels relative to the identified object in the image, where object may include a reflective surface, where ambient light in the space is calculated based on the weighted pixels.
