Under this condition, if the sealing of the mobile phone is not good enough and dust enters, it just covers the effective exposure area of the ambient light sensor, or the user's finger just covers the effective exposure area of the ambient light sensor. It may affect the incident amount of ambient light, so that the amount of ambient light actually irradiated into the effective exposure area of the ambient light sensor is greatly reduced, resulting in increased recognition errors, which may affect the terminal equipment's ability to recognize light-emitting devices (including display screens and keyboard backlights, etc.) effectiveness of control

A method and an apparatus for controlling light emitting elements in a terminal device and a terminal device are disclosed. The method 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. With the present invention, the effectiveness of managing the light emitting elements can be improved.
Description
technical field [0001] The present invention relates to the technical field of light emitting device control, in particular to a light emitting device control method and device in terminal equipment and terminal equipment. Background technique [0002] As people pay more and more attention to green energy saving and intelligent products, ambient light sensors are used more and more. The ambient light sensor can measure and obtain the current ambient light intensity, and automatically adjust the brightness of various light-emitting devices according to the light intensity, optimize brightness control, and reduce product power consumption. Commonly used light-emitting devices include display screens, keyboard backlights, and the like. For example, in mobile applications such as mobile phones, the power consumed by the display is as high as 30% of the total battery power. The ambient light sensor can sense the brightness of the environment, and the mobile phone can reduce the ...
