Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The first embodiment:
as shown in fig. 1, which is one of the flow charts of the steps of the method for controlling the display brightness of the terminal screen in the first embodiment of the present invention, the method includes the following steps:
step 101, when it is detected that the terminal screen is in a working state and the current display brightness of the terminal screen does not change along with the change of the ambient light intensity value, obtaining a current ambient light intensity value and a current brightness level of the terminal screen.
In this step, specifically, when it is detected that the terminal screen is in the working state and the current display brightness of the terminal screen does not change along with the change of the ambient light intensity value, that is, when it is detected that the terminal screen is in the working state and the automatic dimming function of the terminal is in the off state, the current ambient intensity value of the current environment where the terminal is located and the current brightness level of the terminal screen are obtained. Specifically, when the current ambient light intensity value is obtained, the current ambient light intensity value may be obtained by an ambient light sensor of the terminal.
And 102, controlling the display brightness of the terminal screen according to the current environment light intensity value and the preset environment light intensity value, and the current brightness level of the terminal screen and the preset terminal screen brightness level.
In this step, specifically, the display brightness of the terminal screen may be controlled according to the obtained current ambient light intensity value and the current brightness level of the terminal screen, as well as the preset ambient light intensity value and the preset terminal screen brightness level.
Therefore, when the terminal screen is detected to be in the working state and the current display brightness of the terminal screen does not change along with the change of the ambient light intensity value, the display brightness of the terminal screen is controlled according to the obtained current ambient light intensity value and the obtained current brightness level of the terminal screen, the problem that a user cannot clearly see the terminal screen under strong light when the automatic dimming function of the terminal is turned off and the brightness of the terminal screen is low in the prior art is solved, the terminal can automatically adjust the display brightness according to the obtained current ambient light intensity value and the obtained current brightness level of the terminal screen, the screen brightness of the terminal can change along with the change of the ambient light intensity value, and convenience is provided for the user to operate the terminal.
In addition, specifically, when the display brightness of the terminal screen is controlled according to the current ambient light intensity value and the preset ambient light intensity value, and the current brightness level of the terminal screen and the preset terminal screen brightness level, the current display brightness of the terminal screen can be controlled to change along with the change of the ambient light intensity value according to the current ambient light intensity value and the preset ambient light intensity value, and the current brightness level of the terminal screen and the preset terminal screen brightness level; or, according to the current ambient light intensity value and the preset ambient light intensity value, and the current brightness level of the terminal screen and the preset terminal screen brightness level, controlling the display brightness of the terminal screen to be adjusted to a preset brightness value.
Therefore, when the current ambient light intensity value and the current brightness level of the terminal screen are obtained, the current ambient light intensity value can be compared with the preset ambient light intensity value, and the current brightness level of the terminal screen is compared with the preset terminal screen brightness level, wherein when the current ambient light intensity value is greater than or equal to the preset ambient light intensity value and the current brightness level is less than or equal to the preset terminal screen brightness level, the current display brightness of the terminal screen is controlled to change along with the change of the ambient light intensity value. Optionally, when multiple sets of parameters are preset and each set of preset parameters includes an ambient light intensity value and a terminal screen brightness level, the current ambient light intensity value may be respectively compared with the ambient light intensity value in each set of parameters, the current brightness level is compared with the terminal screen brightness level in the same set of parameters, and when the current ambient light intensity value is greater than or equal to the ambient light intensity value in one set of parameters and the current brightness level is less than or equal to the terminal screen brightness level in the same set of parameters as the ambient light intensity value, the current display brightness of the terminal screen is controlled to change along with the change of the ambient light intensity value. In addition, when the current ambient light intensity value is greater than or equal to the preset ambient light intensity value and the current brightness level is less than or equal to the preset terminal screen brightness level, the display brightness of the terminal screen can be controlled to be adjusted to the preset brightness value.
In addition, optionally, when detecting whether the terminal screen is in the working state, the terminal screen can be detected to be in the working state through a front camera of the terminal. Specifically, when the front camera of the terminal detects that a face image exists in front of the terminal screen in a bright screen state, the terminal screen is determined to be in a working state.
Therefore, when the automatic dimming function of the terminal is detected to be turned off, the face detection is carried out through the front camera of the terminal to judge whether the user needs to carry out the next operation, namely whether the terminal screen is in a working state or not, then the current ambient light intensity value is obtained through the ambient light sensor of the terminal to obtain the current ambient light intensity value of the terminal and the current brightness level of the terminal screen, and the current ambient light intensity value and the preset terminal screen brightness level are compared to judge whether the current display brightness of the terminal screen needs to be controlled to change along with the change of the ambient light intensity value or not, namely, the automatic dimming function of the terminal is controlled to be started, or the display brightness of the terminal screen is controlled to be adjusted to a preset brightness value, so that the display brightness of the terminal screen is controlled. Specifically, after the current display brightness of the screen of the control terminal changes along with the change of the ambient light intensity value or the display brightness of the control terminal is adjusted to a preset brightness value, the front camera, the ambient light sensor and the like of the terminal can be turned off, so that the purpose of saving the electric quantity of the terminal is achieved.
Specifically, the above embodiments are further described below with reference to the accompanying drawings. As shown in fig. 2, the implementation steps of the above embodiment are as follows:
step 201, detecting whether a screen of the terminal is in a bright screen state, entering step 202 when the screen of the terminal is detected to be in the bright screen state, detecting whether the current display brightness of the screen of the terminal changes along with the change of the ambient light intensity value, namely, detecting whether an automatic dimming function of the terminal is in an on state, and if not, entering step 203, and turning on a front camera of the terminal. Then, the method enters step 204, a front-facing camera of the terminal detects whether a face image exists in front of a terminal screen in a bright screen state, if so, the method enters step 205, an ambient light sensor of the terminal is turned on, and the method enters step 206, a current ambient light intensity value and a current brightness level of the terminal screen are obtained, and at this time, the obtained current ambient light intensity value and the current brightness level of the terminal screen can be recorded as a set of parameters. Then step 207 is entered, the set of parameters is compared with a plurality of sets of parameters preset by the terminal, wherein each preset set of parameters includes an ambient light intensity value and a terminal screen brightness level, whether the current ambient light intensity value is greater than or equal to the ambient light intensity value in one preset set of parameters or not is judged, and whether the current brightness level is less than or equal to the terminal screen brightness level of the same set of parameters as the ambient light intensity value is judged, if so, it is judged that the terminal screen brightness at this time cannot meet the condition that the user clearly sees the terminal screen under the current ambient light intensity, step 208 is entered, the current display brightness of the terminal screen is controlled to change along with the change of the ambient light intensity value, that is, the automatic dimming function of the terminal is controlled to be turned on, and the front camera and the ambient light sensor are turned off, so.
Therefore, the terminal and the method have the advantages that the current state of the terminal is considered, whether the current display brightness of the terminal screen is controlled to change along with the change of the ambient light intensity value or not is judged according to the preset ambient light intensity value and the preset terminal screen brightness level, namely whether the automatic dimming function is started or whether the display brightness of the terminal is controlled to be adjusted to a preset brightness value or not is controlled, the actual display brightness condition of the terminal screen is considered while the setting state of the terminal is not changed as much as possible, and the actual use scene of a user is better met. In addition, after the display brightness of the terminal screen is controlled, unnecessary peripheral equipment and programs are closed, the display brightness of the terminal screen is automatically controlled under strong light, and meanwhile, the electric quantity of the terminal is saved.
