Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Specifically, referring to fig. 1, in an embodiment of the present invention, a method for adjusting light intensity is provided. The light intensity adjusting method is suitable for a mobile terminal, and the mobile terminal comprises a first light sensor and a second light sensor.
The light intensity adjusting method includes: step S110, starting a first light sensor and a second light sensor to respectively obtain a first light intensity value and a second light intensity value; step S120, calculating a first difference value between the first light intensity value and the second light intensity value; step S130, correspondingly adjusting the brightness value of the display screen of the mobile terminal according to the first difference value; step S140, judging whether the second light sensor meets a preset condition; step S150, when the second light sensor is judged to meet the preset condition, closing the second light sensor, and simultaneously opening the virtual second light sensor to obtain a third light intensity value; step S160, calculating a second difference between the first light intensity value and the third light intensity value; and step S170, correspondingly adjusting the brightness value of the display screen of the mobile terminal according to the second difference value.
Specifically, in step S110, the first light sensor and the second light sensor are turned on to obtain a first light intensity value and a second light intensity value, respectively.
And when the display screen of the mobile terminal is lightened, the first light sensor and the second light sensor are started. The first light sensor and the second light sensor are arranged at the same end of the mobile terminal, and the second light sensor is located near the first light sensor. The first light sensor is disposed to face a detection environment of the mobile terminal and a portion of a display screen of the mobile terminal in a forward direction. The second light sensor is disposed to face only the display screen. The first light sensor detects a detection environment and a part of a display screen of the mobile terminal to obtain a first light intensity value. The second light sensor detects a display screen of the mobile terminal to obtain a second light intensity value.
In step S120, a first difference between the first light intensity value and the second light intensity value is calculated.
The first difference is calculated and may be used as the final ambient light value.
And step S130, correspondingly adjusting the brightness value of the display screen of the mobile terminal according to the first difference value.
In this step, the brightness value of the display screen of the mobile terminal may be adjusted accordingly according to the final ambient light value.
Step S140, determine whether the second light sensor satisfies a predetermined condition.
Referring to fig. 2, in this step, the determining whether the second light sensor satisfies a predetermined condition includes: step S141, dividing a first time period into N time periods according to a second light intensity value obtained by a second light sensor lasting for the first time period, wherein N is a natural number greater than 2; step S142, determining whether a first difference between a second light intensity value obtained by the second light sensor and a first light intensity value obtained by the first light sensor in M consecutive time periods is smaller than a first threshold, where M is a natural number smaller than N; step S143, when it is determined that the first difference is smaller than the first threshold value in the M consecutive time periods, turning off the second light sensor, and simultaneously turning on the virtual second light sensor.
Specifically, in step S141, the first time period is divided into N time periods according to the duration of the second light intensity value obtained by the second light sensor for the first time period, where N is a natural number greater than 2.
For the convenience of understanding, the first time period is divided into N time periods, which is described below by an example.
For example, the duration of the second light intensity value obtained by the second light sensor may be a function light (t) of a time t, the first duration is set as t1, the time for turning on the second light sensor is t0, and the current time is t2, and the duration of the ambient light brightness detected by the second light sensor is divided into a plurality of time segments. Specifically, light (t), t0 is not less than t not more than t 1; light (t), t1 is not less than t not more than 2 t 1; light (t),2 t1 ≦ t ≦ 3 t 1; light (t),3 t1 ≦ t ≦ 4 t 1; … light (t), t2-t1 is less than or equal to t 2.
Step S142, determining whether a first difference between a second light intensity value obtained by the second light sensor and a first light intensity value obtained by the first light sensor in M consecutive time periods is smaller than a first threshold, where M is a natural number smaller than N.
In this step, it is determined whether the first difference is less than a first threshold in the most recent M time periods.
Step S143, when it is determined that the first difference is smaller than the first threshold value in the M consecutive time periods, turning off the second light sensor, and simultaneously turning on the virtual second light sensor.
In this step, the virtual second light sensor is turned on while the second light sensor is turned off. It should be noted that the virtual light sensor may be connected to the second light sensor.
Step S150, when it is determined that the second light sensor satisfies the predetermined condition, turning off the second light sensor, and simultaneously turning on the virtual second light sensor to obtain a third light intensity value.
Referring to fig. 3, in this step, the step of obtaining the third light intensity value includes: step S151, determining a third light intensity value according to an average value of the second light intensity values obtained by the second light sensor in M consecutive time periods.
When the second light sensor is turned off, the ambient light brightness detected by the virtual second light sensor is provided by the light intensity value emitted by the virtual light. Specifically, the virtual rays may be output in a set cycle. For example, if a light duration is set as the first time, the virtual light will cyclically output the light with the set light duration as the first time until the second light sensor is turned on. In other words, a virtual light is set, and the second light sensor is replaced by the generation of the virtual light. The setting of the virtual light is based on the average value of the second light intensity values obtained in the latest continuous M time periods as the third light intensity value. That is, the virtual light will cycle to produce an average of the second light intensity values obtained over the most recent consecutive M time periods.
Further, referring to fig. 4, the step of turning off the second light sensor includes: step S153, judging whether a second duration for closing the second light sensor is greater than a second threshold value; in step S155, when it is determined that the second duration of the second light sensor is greater than the second threshold, the second light sensor is turned on again.
The above steps are performed to replace the ambient light brightness detected by the second light sensor by the virtual light generation, which may cause the ambient light brightness to change.
In the present embodiment, the second threshold is 2 seconds.
In step S160, a second difference between the first light intensity value and the third light intensity value is calculated.
A second difference is calculated and may also be used as the final ambient light value when the second light sensor is turned off.
And step S170, correspondingly adjusting the brightness value of the display screen of the mobile terminal according to the second difference value.
In this step, the brightness value of the display screen of the mobile terminal may be adjusted accordingly according to the final ambient light value.
By executing the steps 110 to 170, the virtual second light sensor is used to replace the second light sensor under a certain condition, and the virtual second light sensor is matched with the first light sensor to detect the ambient light brightness, so that the brightness of the display screen of the mobile terminal is adjusted, the influences of the display content, the brightness and the like of the display screen are avoided, the effectiveness of the detection result is improved, and the use experience of a user is improved.
