Abstract
A method for controlling light emitting elements includes: obtaining a first light intensity value detected by an ambient light sensor in a terminal device and obtaining a second light intensity value detected by an image capturing apparatus in the terminal device under same lighting conditions; determining a standard light intensity value corresponding to the second light intensity value according to a preset mapping between a light intensity value of the image capturing apparatus and a standard light intensity value of the ambient light sensor; obtaining a calibration parameter for the ambient light sensor according to the first light intensity value and the standard light intensity value; obtaining a detected light intensity value detected by the ambient light sensor when light emitting elements in the terminal device need to be controlled; and controlling the light emitting elements in the terminal device according to the detected light intensity value and the calibration parameter.
