Abstract:
1. A method for controlling an electronic device comprising: detecting a first intensity of all light at substantially any wavelength at a first time; detecting a first intensity of infrared light over near-infrared wavelengths at the first time; determining a first intensity of visible light based on a difference between the detected first intensity of all light and the detected first intensity of infrared light; detecting a second intensity of all light at substantially any wavelength at a second time that is after the first time; detecting a second intensity of infrared light over near-infrared wavelengths at the second time; determining a second intensity of visible light based on a difference between the detected second intensity of all light and the detected second intensity of infrared light; when the detected second intensity of infrared light is above a threshold intensity, generating a first control signal for controlling the electronic device based on the determined first intensity of visible light; and when the detected second intensity of infrared light is below the threshold intensity, generating a second control signal for controlling the electronic device based on the determined second intensity of visible light.
