ABSTRACT:
A system and method of ambient light detection with digitized output. A light sensitive device is coupled to electronic circuitry for receiving an output of the light sensitive device corresponding to a level of ambient light. The electronic circuitry compares the output to a threshold level. The threshold level corresponds to a desired level of light. The electronic circuitry for provides an output signal indicative of said desired level of light.
