Body can be found in Fig. 3.
Referring to Fig. 3, Fig. 3 is the second procedure schematic diagram of backlight adjusting method provided by the embodiments of the present application.
Detailed process can be such that
201, the automatic backlight that terminal receives user's triggering adjusts request.
For example, terminal can be generated automatic backlight and adjust request when user opens automatic backlight regulatory function.Work as terminal
When detecting that user opens automatic backlight regulatory function, step 202 is executed；If terminal does not open automatic backlight regulatory function,
The backlight illumination of terminal remains unchanged.
202, terminal opens optical sensor and acceleration transducer, then after receiving the automatic backlight and adjusting request
Execute step 203.
For example, terminal after receiving the automatic backlight and adjusting request, can be adjusted according to the automatic backlight and be requested, generate
It opens optical sensor instruction and opens acceleration transducer instruction, instructed according to the unlatching optical sensor and open optical sensor, with
And it is instructed according to the unlatching acceleration transducer and opens acceleration transducer.
Wherein, which may include ambient light sensor, infrared light transducer[sensor, sun optical sensor or ultraviolet light
Sensor etc. is not especially limited herein.And acceleration transducer may include condenser type, inductance type, strain-type, pressure drag
Formula, piezoelectric type etc., are not especially limited herein.
203, terminal is monitored the light sensation value and position angle of itself (i.e. the terminal).
Real-time monitoring is carried out to the light sensation value of the terminal for example, specifically can use the optical sensor, utilizes the acceleration
Sensor carries out real-time monitoring to the position angle of the terminal.For example, the light sensation value of a certain moment optical sensor monitoring terminal is
170lux, acceleration transducer monitor that the position angle of terminal is 5 °.
204, when the light sensation value and/or position angle that monitor the terminal change, terminal obtains itself (i.e. end
End) light sensation value and/or position angle changing value size.
For example, obtaining light sensation value and the position of the terminal when monitoring that the light sensation value of the terminal and position angle change
The size of angle setting degree changing value, or the light sensation value or position angle when changing of the terminal, obtain the light sensation value of the terminal
With the size of position angle changing value.For example, it is 0 ° that the light sensation value of the terminal, which becomes 180lux and the position angle of terminal, then
The changing value size of the light sensation value of the terminal is 10lux, and the changing value size of the position angle of the terminal is 5 °.
If 205, the light sensation value changing value of the terminal is greater than the first preset threshold and/or position angle changing value and is greater than the
Two preset thresholds, then terminal judges whether itself (i.e. the terminal) is in use state, if so, 206 are thened follow the steps, if it is not,
Then the backlight illumination of terminal remains unchanged.

In memory and be sent to terminal, etc..For example, the first preset threshold of setting is 5lux, the first preset threshold of setting is 3 °,
If the light sensation value changing value of the terminal is greater than the first preset threshold and position angle changing value is greater than the second preset threshold, judge
Whether the terminal is in use state, alternatively, if the light sensation value changing value of the terminal is greater than the first preset threshold or position angle
Changing value is greater than the second preset threshold, then judges whether the terminal is in use state.

The current location angle of the terminal is obtained with the acceleration transducer of unlatching.For example, the current light sensation value of the terminal got
The current location angle " 0 ° " of " 180lux " and the terminal.
207, according to the current light sensation value and current location angle, terminal uses default calibration algorithm to simulate itself and (is somebody's turn to do
Terminal) environmental light brightness.
Wherein, if the current light sensation value of the terminal got and current location angle use in preset data table
Default calibration algorithm simulates the environmental light brightness of the terminal, can be with are as follows: quickly searches corresponding environment using preset data table
Brightness.
For example, according to the current light sensation value " 180lux " of the terminal got and the current location angle of the terminal
" 0 ° " then uses preset data table (such as table 1) to search corresponding environmental light brightness quickly as 200lux.
Correspondingly, if the current light sensation value of the terminal got and current location angle not in preset data table,
According to the current light sensation value and current location angle, corresponding environmental light brightness is calculated using preset function relationship.
For example, if the current light sensation value " 190lux " of the terminal got and the current location angle " 5 ° " of the terminal,
Then use the corresponding environmental light brightness of preset function relationship calculating for 210lux, and so on, etc..
208, terminal adjusts the backlight illumination of itself (i.e. the terminal) according to the environmental light brightness.
For example, the terminal can be adjusted according to the corresponding relationship of environmental light brightness preset in terminal and backlight illumination
Backlight illumination, the corresponding relationship of the environmental light brightness and backlight illumination is built-in adjusting terminal in the terminal before factory
Backlight illumination, subsequent can also reset.
From the foregoing, it will be observed that the terminal of the present embodiment after the automatic backlight for receiving user's triggering adjusts request, is opened light and is passed
Sensor and acceleration transducer, and the light sensation value and position angle of itself (i.e. the terminal) are monitored, then, when monitoring
When the light sensation value and/or position angle of the terminal change, terminal obtains the light sensation value and/or position of itself (i.e. the terminal)
The size of angle change value, then, if the light sensation value changing value of the terminal is greater than the first preset threshold and/or position angle becomes
Change value is greater than the second preset threshold, then terminal judges itself (i.e. the terminal) whether in use state, subsequently, if the terminal
In use state, then terminal obtains itself (i.e. the terminal) current light sensation value and current location angle, and using default calibration
