Background The automatic brightness adjustment of the display screen along with the brightness of the external environment is a basic function of electronic equipment such as a mobile phone, when the external environment becomes bright, the brightness of the display screen of the mobile phone is automatically adjusted up, and when the external environment becomes dark, the brightness of the display screen of the mobile phone is automatically adjusted down. Currently, in the process of adjusting the brightness of a display screen, the brightness of the display screen is adjusted according to ambient light collected by an ambient light sensor arranged below the display screen. However, since the light emitted by the display screen is partially reflected to the ambient sensor, the ambient light collected by the ambient light sensor includes the reflected light of the display screen, resulting in lower adjustment accuracy for adjusting the brightness of the display screen according to the ambient light. Therefore, how to accurately detect the ambient light of the environment where the display screen is located is a technical problem to be solved.

According to the scheme provided by the application, the ambient light of the environment where the display screen is positioned is detected according to the ambient light data acquired by the ambient light sensor and the reflected light data of the display screen, so that the reflected light data in the ambient light data acquired by the ambient light sensor can be effectively removed, and the detection accuracy of detecting the ambient light is improved. In some alternative embodiments, determining that the ambient light sensor collects the reflected light data of the display screen includes determining a reflected light color mixing coefficient of the reflected light reflected by the display screen to the ambient light sensor when the display screen displays a white map, and determining the reflected light data according to the reflected light color mixing coefficient.
