The intensity level of final ambient light.First preset value can be set based on experience value.
In one embodiment, it is in order to further improve accuracy, described according to first light intensity value and second light
The step of intensity values determine the intensity level of ambient light includes：
Minima in S1033, acquisition first light intensity value and second light intensity value.
For example, first light intensity value and second light intensity value are compared by terminal, if first light intensity value less than this
Two light intensity values, then using first light intensity value as minima.If second light intensity value be less than first light intensity value, by this second
Light intensity value is used as minima.If second light intensity value is equal to first light intensity value, by second light intensity value or first light
Intensity values are used as minima.
S1034, the intensity level that the ambient light is worth to according to the minimum.
For example, in one embodiment, terminal can be adjusted to the meansigma methodss by the second preset value and obtain the ring
The intensity level of border light.Such as, the meansigma methodss can be multiplied by the intensity level that parameter preset obtains final ambient light by terminal.This
Two preset values can be set based on experience value.
In one embodiment, it is described the ambient light is worth to according to the minimum intensity level the step of include：
Difference between S201, acquisition first light intensity value and second light intensity value.
For example, terminal obtains the difference between first light intensity value and second light intensity value.
S202, default adjusted value is obtained according to the difference.
For example, in one embodiment, terminal is stored and multiple preset difference values in data base in advance, each preset difference value
It is correspondingly arranged a preset value.Specifically, terminal searches preset difference value corresponding with the difference in presetting database, and should
The corresponding preset value of preset difference value is used as the default adjusted value.
S203, the intensity level for obtaining the ambient light is adjusted according to the default adjusted value to the minima.
For example, the preset difference value and default adjusted value are carried out into default computing, obtains the intensity level of final ambient light.Than
The preset difference value is multiplied by into the default adjusted value such as, the intensity level of final ambient light is obtained.
For the ease of being adjusted to the brightness of screen, and the motility of terminal is improved, said method can also include：
S104, the brightness that screen is adjusted according to the intensity level of the ambient light.
For example, brightness of the intensity level of the ambient light that terminal is obtained according to above-mentioned steps S103 to screen is adjusted, with
Make display effect more preferably.Wherein, when the intensity level of ambient light is larger, the brightness of screen is heightened by terminal.It is strong when ambient light
When angle value is less, the brightness of screen is turned down by terminal.
Due to the control method of existing screen intensity, mainly it is determined by the data of single ambient light sensor, because
Easily there is the situation of erroneous judgement in this.
The control method of the screen intensity of the present embodiment, due to the first light intensity by obtaining first environment optical sensor
Value；Obtain the second light intensity value of second environment optical sensor；Ring is determined according to first light intensity value and second light intensity value
The intensity level of border light, the brightness that screen is adjusted according to the intensity level of the ambient light.Due to by the light of two ambient light sensors
Intensity values determine the intensity of final ambient light, when object can have been avoided to shelter from ambient light sensor, ambient light sensor
There is deviation in detected value, so as to improve the detection accuracy of ambient light.Secondly as the intensity of ambient light is more accurate more favourable
In by the brightness adjustment of screen to suitable brightness, such that it is able to prevent the maloperation of terminal.In addition, when the brightness adjustment of screen
When suitable brightness, display effect can also be improved.
