It is added, divided by the number of pixel, the current brightness value of the screen area corresponding to build environment optical sensor.Wherein it is possible to
In the image of the screen area is got, by the red component, green component and blue component of each pixel (red,
Green, blue, RGB) tone, saturation degree and brightness value (Hue, saturation, value, HSV) are converted to, obtain each
The brightness value of pixel.
Step S202, average brightness value is calculated according to the brightness value of each pixel, and determines that average brightness value is environment
The current brightness value of screen area corresponding to optical sensor, repeatedly obtains to obtain multiple brightness values.
In one embodiment, before the brightness value of each pixel is obtained, it can also judge whether electronic equipment is bright
Screen state, if so, then obtaining the image that screen is currently shown, it is right then further to obtain ambient light sensor institute among the image
The brightness value of each pixel in the image-region answered.Specifically, screen is in bright screen state as trigger condition, when passing through
The process of system application is monitored, to judge whether the screen of electronic equipment is in bright screen state, when listening to electricity
When appearance formula touch-screen is lit, represents that screen is in bright screen state, that is, obtain the image that screen is currently shown
Step S203, contrasts multiple brightness values, determines that minimum brightness value is target brightness value, target brightness value

Value can be identical with step S204.
Step S206, calculates the difference between the second light intensity value and the first light intensity value.
Step S207, judges whether difference is less than preset value, if so, step S208 is then performed, if it is not, then terminating flow.
In actual use, since above-mentioned multiple ambient light sensors are arranged at the display area of screen, and show
Region is also the touch area of electronic equipment, therefore when user carries out touch control operation on an electronic device, it is understood that there may be user
Finger or other things block above ambient light sensor causes the light intensity value of measurement inaccurate, therefore may determine that target
Whether ambient light sensor is blocked, if not being blocked, continues to execute next step.
Wherein, it is above-mentioned judge whether target environment optical sensor is blocked can be by judging that above-mentioned sensor of interest measures
One light intensity value of ground and the second light intensity value for measuring of other ambient light sensors between difference whether be less than preset value, by
In when one in multiple ambient light sensors in electronic equipment is blocked, which passes with other ambient lights
Light intensity value gap measured by sensor can be bigger, therefore judges whether target environment optical sensor is hidden using the program
Gear.If the difference of the second light intensity value and the first light intensity value is less than preset value, it is determined that the target environment optical sensor not by
Block, then further perform step S208.
Step S208, calculates the first light intensity value and the difference of target brightness value, and determines that the difference is target luminous intensity
Value.
In the embodiment of the present invention, it is arranged on due to ambient light below the display area of screen, the brightness of screen will
Measurement to ambient light photo sensor interferes.Specifically, can by by the first light intensity value subtract target brightness value come
Target light intensity value is calculated, which is more nearly the light intensity value of current environment light.
Electronic equipment is after target light intensity value is obtained, you can the brightness of display screen is adjusted according to the ambient light intensity,
Realize the automatic adjustment of brightness.
From the foregoing, it will be observed that the embodiment of the present application can obtain each pixel in screen area corresponding to ambient light sensor
Brightness value, according to the brightness value of each pixel calculate average brightness value, and determine average brightness value be ambient light sensor
The current brightness value of corresponding screen area, repeatedly obtains to obtain multiple brightness values, multiple brightness values is contrasted, really
Fixed minimum brightness value is target brightness value, and the ambient light sensor corresponding to target brightness value is target environment optical sensor,
The first currently detected light intensity value of target environment optical sensor is obtained, obtains the ambient light outside target environment optical sensor
The second currently detected light intensity value of sensor, calculates the difference between the second light intensity value and the first light intensity value, judges
Whether difference is less than preset value, if so, then calculating the first light intensity value and the difference of target brightness value, and determines that the difference is mesh
Mark light intensity value.The application selects corresponding screen area brightness minimum by setting multiple ambient light sensors in the terminal
