Subject to carry out backlight illumination adjusting, can when the light sensor of mobile terminal is blocked, improve backlight illumination adjust
Accuracy.
Referring to Fig. 4, Fig. 4 is another flow diagram for throwing screen brightness adjusting method disclosed in the embodiment of the present application,
Fig. 4 advanced optimizes to obtain on the basis of Fig. 1 b.As shown in figure 4, the throwing screen brightness adjusting method includes the following steps.
401, after mobile terminal and display terminal establish connection, the broadcasting content of mobile terminal is transmitted to display eventually
End, display terminal is for showing broadcasting content.
402, mobile terminal by light sensor obtain first environment luminous intensity, mobile terminal according to ambient light intensity with
The correspondence of backlight illumination determines the first backlight illumination corresponding with first environment luminous intensity.
403, mobile terminal notifies display terminal to show broadcasting content with the first backlight illumination.
Step 401-403 in the embodiment of the present application may refer to the step 101-103 shown in Fig. 1 b, no longer superfluous herein
It states.
Optionally, after executing 401, following operation can also be performed：
(11) mobile terminal detection whether there is the touch control operation for mobile terminal in preset duration；
(12) if it is not, then mobile terminal closes the display screen of mobile terminal.
In the embodiment of the present application, preset duration can be set in advance, and be stored in the non-volatile of mobile terminal and deposited
In reservoir.Preset duration generally could be provided as being less than 10 minutes.For example, it is 30 seconds or 1 minute that preset duration, which can be arranged,
Or 2 minutes, the embodiment of the present application does not limit.Mobile terminal in the embodiment of the present application be can touch-control mobile terminal, use
Family can realize human-computer interaction by the interface of touch-control mobile terminal.If there is no for mobile whole within the scope of preset duration
The touch control operation at end shows that user does not have operating handset, can be by the display of mobile terminal in order to save the electricity of mobile terminal
Screen is closed.When the broadcasting content of mobile terminal is transmitted to display terminal, the display screen of mobile terminal can not have to light, to save
The electricity of mobile terminal.
404, mobile terminal determines that light sensor obtains the fluctuating range of ambient light intensity.
405, when fluctuating range is more than predetermined amplitude threshold value, mobile terminal identifies the scene residing for mobile terminal.
406, mobile terminal determines target backlight luminance corresponding with the scene residing for mobile terminal.
407, mobile terminal notifies display terminal to show broadcasting content with target backlight luminance.
In the embodiment of the present application, mobile terminal can periodically obtain ambient light intensity by light sensor.For example,
Mobile terminal can be by light sensor every obtaining an ambient light intensity in 1 second.
Mobile terminal determines that the fluctuating range that light sensor obtains ambient light intensity includes：When mobile terminal determines default
Between difference in multiple ambient light intensities for obtaining in range between maximum ambient light intensity and the ambient light intensity of minimum, will
Fluctuating range of the difference as ambient light intensity.Wherein, preset time range is generally less than 10 minutes, for example, preset time
Range could be provided as 30 seconds, 45 seconds, 60 seconds etc., and the embodiment of the present application does not limit.
Wherein, predetermined amplitude threshold value can be set and is stored in the nonvolatile memory of mobile terminal in advance,
Predetermined amplitude threshold value can be set and be less than 500lux, for example, could be provided as appointing in 200lux, 300lux, 400lux
Meaning one.
When fluctuating range is more than predetermined amplitude threshold value, then it is assumed that mobile terminal is in the scene that ambient light changes greatly,
For example, the throwing screen scene that the throwing screen scene on expressway, indoor light change greatly.Mobile terminal can pass through camera, GPS
Module identifies the scene residing for mobile terminal.Under different scenes, different brightness adjustment strategies can be corresponded to.For example,
In throwing screen scene on expressway, since ambient enviroment quickly changes, if the brightness of display terminal quickly changes,
User experience can be influenced instead.The ambient light intensity that can be then arranged under the throwing screen scene on expressway is corresponding with backlight illumination
Relationship.As shown in table 2, table 2 be ambient light intensity under the throwing screen scene on a kind of expressway disclosed in the embodiment of the present application with
The mapping table of backlight illumination.
Table 1
From table 2 it can be seen that when ambient light intensity is in different ranges, corresponding backlight illumination differs.Citing comes
It says, if ambient light intensity is between the luxs 500-2000 (lux), corresponding backlight illumination is maximum backlight illumination
50%.
As can be seen that being compared with table 1, the sensibility of the backlight illumination adjustment in table 2 is smaller, is not compromised by ambient light hair
It send small change and frequently adjusts backlight illumination, avoid the occurrence of and frequently adjust backlight under the scene that ambient light changes greatly
The case where brightness.
Table 2 is the mapping table of the ambient light intensity and backlight illumination under the throwing screen scene on expressway.Indoor light
Ambient light intensity under the throwing screen scene changed greatly can be different with table 2 from the mapping table of backlight illumination.
In the embodiment of the present application, when display terminal can not automatically adjust the backlight illumination of display terminal, display terminal
The backlight illumination of display terminal can be controlled by mobile terminal, it can be when display terminal shows broadcasting content, according to movement
The display brightness of the ambient light intensity adjust automatically display terminal of terminal acquisition, to improve the vision that user watches display terminal
Experience.When detecting that the fluctuating range of ambient light intensity is larger, the scene residing for mobile terminal can be identified, according to scene pair
The mapping table of the ambient light intensity and backlight illumination answered is avoided the occurrence of and is changed greatly in ambient light adjusting backlight illumination
The case where backlight illumination is frequently adjusted under scene.
