Problems solved by technology
[0003] However, limited by the layout structure of the ambient light sensor in the electronic device, the range of light angles that the ambient light sensor can sense is relatively limited, and it is easy for the ambient light sensor to fail to accurately detect the brightness of the ambient light. The ambient light received cannot realize backlight adjustment accurately and reliably

Embodiment Construction
[0046] The scheme of the embodiment of the present application is suitable for adjusting the brightness of the backlight of the display screen of the electronic equipment based on the ambient light of the electronic equipment. The scheme of the present application improves the accuracy of the adjustment of the backlight brightness and reduces the error caused by errors when the ambient light does not change. Abnormal situations such as frequent changes in screen brightness caused by detection.
[0047] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this ap...

The invention provides a backlight adjusting method and device and electronic equipment, and the method comprises the steps of obtaining an ambient light induction value sensed by an ambient light sensor, the ambient light induction value being used for representing the ambient light brightness of the environment where the electronic equipment is located; obtaining a photosensitive parameter value sensed by the image sensor; if it is determined that the ambient light brightness of the environment where the electronic equipment is located changes based on the light sensing parameter value sensed by the image sensor, controlling the backlight brightness of a display screen of the electronic equipment based on the ambient light sensing value; if it is determined that the ambient light brightness of the environment where the electronic equipment is located does not change based on the photosensitive parameter value sensed by the image sensor, keeping the backlight brightness of the display screen unchanged. According to the scheme, backlight error adjustment of the display screen can be reduced, and more accurate backlight adjustment is achieved.
Description
technical field [0001] The present application relates to the technical field of control, and in particular to a backlight adjustment method, device and electronic equipment. Background technique [0002] The backlight adjustment of the electronic device refers to automatically adjusting the brightness of the backlight of the display screen of the electronic device based on the ambient light intensity sensed by the ambient light sensor of the electronic device. [0003] However, limited by the layout structure of the ambient light sensor in the electronic device, the range of light angles that the ambient light sensor can sense is relatively limited, and it is easy for the ambient light sensor to fail to accurately detect the brightness of the ambient light. The ambient light received cannot realize backlight adjustment accurately and reliably. Contents of the invention [0004] The present application provides a backlight adjustment method, device and electronic equipmen...
