[0002] In related technologies, electronic devices generally have an automatic screen brightness adjustment function. After the screen brightness automatic adjustment function is turned on, the screen brightness of the electronic device will increase and decrease with the brightness of the ambient light. However, the above The screen brightness adjustment function only considers the change of ambient light brightness, but does not consider other factors, resulting in a narrow application range of screen brightness adjustment, which cannot meet more requirements

The invention discloses a control method which is used to control the screen brightness of an electronic device. The control method comprises the following steps: detecting the ambient brightness and calculating a first brightness value corresponding to the ambient brightness; detecting the background color of screen display; keeping the screen brightness at the first brightness value; or, processing the first brightness value and a predetermined brightness repair value to get a second brightness value, and keeping the screen brightness at the second brightness value. The invention further discloses a control device. According to the control method and the control device in the embodiments of the invention, the ambient brightness and the background color of screen display are taken into full account in adjustment of the screen brightness of the electronic device, so the screen brightness is more appropriate, screen brightness adjustment is more accurate, the application range of screen brightness adjustment is expanded, more requirements are satisfied, and the user's vision is better protected.
Description
technical field [0001] The invention relates to eye protection technology, in particular to a control method and a control device. Background technique [0002] In related technologies, electronic devices generally have an automatic screen brightness adjustment function. After the screen brightness automatic adjustment function is turned on, the screen brightness of the electronic device will increase and decrease with the brightness of the ambient light. However, the above The screen brightness adjustment function only considers the change of ambient light brightness, but does not consider other factors, resulting in a narrow application range of screen brightness adjustment, which cannot meet more requirements. Contents of the invention [0003] The embodiments of the present invention aim to solve at least one of the technical problems in the prior art. Therefore, the embodiments of the present invention need to provide a control method and a control device. [0004] ...
