Abstract
Ambient light is sensed for use in determining luminous flux. According to an example embodiment, ambient light is sensed using two light sensor arrangements that respectively respond differently to light of different relative wavelengths. The output of the sensors is nonlinearly combined to generate data indicative of the luminous flux. This luminous flux data is used to generate a control output for controlling an electronic display.
