LOW POWER GLARE SENSOR

摘要

The invention may be embodied as a glare detection system or as a method of detecting glare. In a system according to the invention, there may be a light receiving surface, a first input channel, a second input channel, a glare signaling circuit and a glare reducing circuit. The first input channel may provide an indication of the amount of light impinging on a first portion of the light receiving surface. The second input channel may provide an indication of the amount of light impinging on a second portion of the light receiving surface. The glare signaling circuit ("GSC") may have a first input port in communication with the first input channel, a second input port in communication with the second input channel, a logic-or gate capable of producing an output signal when the logic-or gate detects that the first input channel or the second input channel indicates glare on the light receiving surface. The glare reducing circuit ("GRC") may be in communication with the logic-or gate, and may be capable of reacting when the logic-or gate produces the output signal. For example, the GRC may react by determining where on the light receiving surface glare exists.
