Abstract

Embodiments of this application relate to the field of terminals, and provide a method and an apparatus for detecting a flicker frequency of an ambient light source, and an electronic device, so as to detect the flicker frequency of the ambient light source with high detection precision and low costs. The electronic device includes a light intensity sensing module, an analog-to-digital conversion module, and a data processing module. The light intensity sensing module is connected to the analog-to-digital conversion module. The analog-to-digital conversion module is connected to the data processing module. The light intensity sensing module includes a photodiode. The light intensity sensing module is configured to detect a light intensity signal of an ambient light source, and convert the light intensity signal into an analog voltage signal. The analog-to-digital conversion module is configured to convert the analog voltage signal into a digital voltage signal. The analog-to-digital conversion module is an audio chip. The audio chip is connected to a microphone and/or a loudspeaker. The data processing module is configured to calculate a flicker frequency of an ambient light source based on the digital voltage signal.
