发明名称 Ambient light sensor with reduced sensitivity to noise from infrared sources
摘要 Systems and methods are provided for detecting ambient light with reduced sensitivity to infrared sources. An electronic device may include an infrared sensor, an ambient light sensor, a decoder, and a processor. The infrared sensor may detect an intensity of infrared light. The ambient light sensor may be configured to detect incident light and to generate an electronic signal indicative of an intensity of visible light. The decoder may be configured to receive the intensity of infrared light and to generate an intensity of decoded infrared light. The processor, which may be coupled to the decoder and the ambient light sensor, may be configured to substitute an alternate electronic signal for the electronic signal if the intensity of infrared light exceeds a threshold amount.
