Abstract

The invention provides a brightness adjustment system of an electronic device display screen and a brightness adjustment method of the electronic device display screen. An electronic device comprises a shooting device. The system comprises a setting module, a shooting module, a calculating module and an adjusting module. The setting module is used for setting displayed brightness of the display screen into N brightness grades, and dividing the brightness value range of an image shot by the shooting device into N brightness value sections according to the N brightness grades set, and ensures that each divided brightness value section corresponds to a brightness grade; the shooting module is used for starting the shooting device at intervals to once shoot the current using environment of the electronic device to obtain a scene image of the current using environment; the calculating module is used for calculating the brightness value of the scene image; and the adjustment module is used for adjusting displayed brightness of the display screen into a brightness grade corresponding to the brightness value section according to the brightness value section where the brightness value of the scene image is located.

Description

technical field [0001] The invention relates to a system and method for adjusting brightness of a display screen of an electronic device. Background technique [0002] Users of electronic devices such as mobile phones often adjust the brightness value of the display screen of the electronic device according to their usage habits or changes in ambient light, so that the user can watch the screen more comfortably. This method of manually adjusting the brightness of the display screen is cumbersome and not user-friendly enough. To solve the above problems, many electronic devices use light sensing elements, such as light sensors, to sense the brightness of ambient light, and automatically adjust the brightness value of the display according to the brightness of the ambient light. However, this automatic brightness adjustment method needs to add an additional light sensing element, which increases the cost. Contents of the invention [0003] In view of the above, it is neces...
