Zusammenfassung:Methods and systems for estimating the amount of visible light in a light source using an image sensor, e.g., such as an image sensor of the type commonly found in color video cameras. The methods and systems may be implemented to use information about the normalized differences of three color components contained in a light source in conjunction with a measure of total light energy of the light source in order to estimate the amount of visible light present in light received by the image sensor from a light source.
