The screen 140 may be used to show a screen brightness adjustment interface including a progress bar of screen brightness, and in the manual brightness adjustment mode, a user may drag the progress bar to manually set a screen brightness value.
Referring to fig. 1B, fig. 1B is a schematic flow chart of a brightness adjustment method according to an embodiment of the present disclosure, where the brightness adjustment method described in the present embodiment is applied to the electronic device shown in fig. 1A, and the brightness adjustment method includes:
101. when the electronic equipment is in a manual brightness adjusting mode and bright screen operation is detected, a first ambient light brightness value is detected through a light sensation sensor, and the manual brightness adjusting mode corresponds to a preset screen brightness value.
In this application embodiment, electronic equipment can awaken the light sense sensor when detecting the bright screen operation, detects first environment light brightness value through the light sense sensor, and from turning off the screen state to bright screen state, the determinable user wants to watch the screen, just then awaken the light sense sensor and detect first environment light brightness value to reduce the electric quantity that consumes because of the light sense sensor lasts work.
The first environment light brightness value of the environment where the electronic device is located can be detected when the user moves from a darker environment to a brighter environment or moves from the brighter environment to the darker environment through the light sensation sensor in a preset time period, wherein the preset time period can be set by a system default or the user sets the time period by himself.
Alternatively, the electronic device may detect whether the user is watching the screen through the camera, and may detect the first ambient light brightness value through the light-sensing sensor when detecting that the user is watching the screen.
The preset screen brightness value is set by a user in a manual brightness adjustment mode, and the first time when the user sets the preset screen brightness value is earlier than the second time when the electronic equipment detects the first ambient light brightness.
102. And acquiring a second ambient light brightness value corresponding to the preset screen brightness value.
In the embodiment of the application, the second ambient light brightness value corresponding to the preset screen brightness value is obtained, the second ambient light brightness value of the first time can be detected by the light sensor at the first time when the user manually sets the preset screen brightness value, specifically, the second ambient light brightness value is detected at the first time and stored in the memory, and the second ambient light brightness value is retrieved from the memory after the first ambient light brightness value is detected at the second time. Alternatively, considering that in the implementation process, when the light sensor is blocked, the result detected by the light sensor may not match the actual ambient light brightness value, and therefore, a plurality of ambient light brightness values in a specified time period may be collected, and the maximum value of the plurality of ambient light brightness values may be used as the second ambient light brightness value, for example, within 3s after the preset screen brightness value is manually set, 3 ambient light brightness values may be collected, and the maximum value of the 3 ambient light brightness values may be used as the second ambient light brightness value.
103. And if the difference value between the second environment light brightness value and the first environment light brightness value is not in a preset range, switching the manual brightness adjusting mode to an automatic brightness adjusting mode, and adjusting the screen brightness according to the first environment light brightness value.

In the embodiment of the application, the electronic device performs fitting according to the corresponding relationship between the ambient light brightness value and the manual adjustment screen brightness value in the multiple historical adjustment records to obtain a fitting function reflecting the corresponding relationship between the ambient light brightness value and the manual adjustment screen brightness value, wherein the ambient light brightness value is an independent variable of the fitting function, the screen brightness value is a dependent variable, the first ambient light brightness value is brought into the fitting function to obtain a corresponding target screen brightness value, and the historical adjustment records reflect the visual perception of human eyes of a user, so that the obtained fitting function better meets the brightness adjustment requirement of the user, and the obtained target screen brightness value meets the visual perception of the user.
Alternatively, in a specific implementation, considering that the user's requirement for the screen brightness is influenced by the user's eye fatigue degree under the same ambient light brightness value, for example, when the ambient light brightness value is 800lux, the user's eye is not tired, the first screen brightness value is set to 467nits, the user's eye is tired, and the second screen brightness value is set to 430nits, so that the user's eye fatigue degree can be detected and the fatigue degree level belonging to the fatigue degree can be determined each time the user manually adjusts the screen brightness, the fatigue degree level is recorded in the corresponding history adjustment record, and data of three dimensions including the fatigue degree, the screen brightness value and the ambient light brightness value in each history adjustment record can be constructed, further, a plurality of fitting functions of the user under different fatigue degree levels can be constructed, each fatigue degree level corresponds to one fitting function, when the screen brightness is adjusted according to the first ambient light brightness value, the current fatigue level of the user can be determined, then the target fitting function corresponding to the fatigue level is determined, and then the target screen brightness value is determined according to the target fitting function.
Optionally, when the screen brightness is adjusted to the target screen brightness value, an absolute value of a difference between a preset screen brightness value and the target screen brightness value may be obtained, a target adjustment number corresponding to the absolute value may be determined according to a corresponding relationship between the preset absolute value and the adjustment number, and multiple adjustments may be performed according to the target adjustment number, specifically, when the absolute value is larger, the corresponding adjustment number may be set to be larger, and when the absolute value is smaller, the corresponding adjustment number may be set to be smaller, so that, when the electronic device performs adjustment each time, a user may not experience badly due to a sudden and large adjustment of the screen brightness.
It can be seen that, in the brightness adjusting method described in the embodiment of the application, when the electronic device is in the manual brightness adjusting mode and detects a bright screen operation, the light sensor detects a first ambient light brightness value, the manual brightness adjusting mode corresponds to a preset screen brightness value, and a second ambient light brightness value corresponding to the preset screen brightness value is obtained, if a difference between the second ambient light brightness value and the first ambient light brightness value is not within a preset range, the manual brightness adjusting mode is switched to the automatic brightness adjusting mode, and the screen brightness is adjusted according to the first ambient light brightness value, so that the screen brightness adjusting mode can be flexibly switched, and the screen brightness adjustment is more intelligent.
