Problems solved by technology

However, if the fixed sampling frequency is set too high, it will lead to excessive power consumption of the mobile phone; and if the fixed sampling frequency is set low, it will make the acquisition speed of light-sensing data slower, resulting in a slower calculation of the backlight value of the mobile phone display screen. Slow, which affects the backlight setting of the mobile phone, especially when the mobile phone is from the screen off to the bright screen state, the mobile phone cannot quickly obtain the light sensitivity value corresponding to the current environment and output the corresponding backlight value, the backlight value setting is low, and the user experience is poor

Abstract

The embodiment of the present invention discloses a screen brightness output method and device, wherein the method includes: monitoring the state of the display screen of the user equipment; Screen brightness corresponding to a light-sensing value, the first light-sensing value is a light-sensing value obtained from a light sensor disposed on the user equipment at a first sampling frequency; when the display screen is in a bright screen state, Outputting the screen brightness corresponding to the second light-sensing value, the second light-sensing value is the light-sensing value obtained from the light sensor at a second sampling frequency, and the first sampling frequency is higher than the second sampling frequency . By implementing the embodiments of the present invention, the backlight setting efficiency of the user equipment can be improved and excessive power consumption of the equipment can be avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a screen brightness output method and device. Background technique [0002] At present, user equipment such as mobile phones are generally set with an automatic backlight mode so that the screen brightness output by the mobile phone can adapt to the current environment. According to the light sensitivity value, the screen brightness that the mobile phone currently needs to output is calculated, so as to realize the function of automatic backlighting of the screen. [0003] In practical applications, the mobile phone reads the light sensitivity value corresponding to the current environment from the light sensor at a fixed sampling frequency. However, if the fixed sampling frequency is set too high, it will lead to excessive power consumption of the mobile phone; and if the fixed sampling frequency is set low, it will make the acquisition speed of light-sensing data slower...
