The intensity level of ambient light is redefined, according to the intensity level of the ambient light for redefining, the brightness of terminal screen is adjusted.
For example, when the intensity level of the ambient light for obtaining is less than by the intensity level that formula lux=ray × a-ir × b is calculated
During setting value, the intensity level of the ambient light that will can be calculated by the full spectrum of ambient light is used as the strong of the ambient light for redefining
Angle value.If under low light environment, a is that 1, b is 2, by calculating the value of ray for the value of 10, ir is 5, by formula lux=ray
The intensity level of the ambient light that × a-ir × b is calculated is 0, and by the intensity level (0) of ambient light, the brightness value that can control screen is

It should be noted that the exemplary intensity level using the light calculated based on the full spectrum of ambient light of the present embodiment is used as again
The intensity level of the ambient light of determination, but a kind of only example of the present embodiment, redefine for the intensity level of ambient light
Method can also be other forms, to realize accurately calculating the intensity level of the light under low light environment.

It is compared, the intensity level of the ambient light redefined based on comparative result.
Specifically, when the intensity level of the corresponding light of full spectrum is more than the dim light threshold value for setting, dim light threshold value is made
It is the intensity level of ambient light for redefining, makes light intensity value of the intensity level of the ambient light for redefining under low light environment
Within the scope of, improve the accuracy that ambient light intensity is calculated.In the present embodiment, the full spectrum calculated using the full spectrum of ambient light

Spend the accuracy for calculating, it is to avoid the situation that ambient light intensity is easily zeroed.When the intensity level of the corresponding light of full spectrum is less than dim light
During threshold value, ray values do not change in register, using the original value of ray values as the ambient light for redefining intensity level.
In the present embodiment, for example, when the intensity level of ambient light for obtaining is less than setting value (or being 0),
If the intensity level of the light of the calculating based on full spectrum is 14, the dim light threshold value for setting is 10, because 14 more than 10, so will be weak
Light threshold value 10 is revised as 10, modification using by the value in ray registers as the intensity level of the ambient light for redefining by 14
The value of ray afterwards as the ambient light for redefining intensity level.If the intensity level of the light calculated based on full spectrum is 5, due to 5
Less than 10, the intensity level 5 of the light that full spectrum is calculated as the intensity level of the light for redefining will be based on, the value (5) of ray is not repaiied
Change.Thus, when obtain ambient light intensity level be less than setting value when, the intensity level of the ambient light for redefining be consistently less than or
Person is equal to dim light threshold value, terminal is accurately judged that current environment is low light environment, realizes to the luminous intensity under low light environment
