SPECTRALLY-SENSITIVE LIGHT FILTER ARRANGEMENT AND APPROACH THEREFOR
Ambient light is sensed using a filtering approach. According to an example embodiment of the present invention, conductive structures (e.g., 120) are used to filter light at different wavelengths for different regions of a light sensor (e.g., 110). The filtered light is sensed or detected, and is used together with known filtering aspects (e.g., knowledge of a wavelength range of incident light) for one or more of a variety of purposes.
