Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
The embodiment of the invention provides a display brightness control method and device, electronic equipment and a computer readable storage medium. In particular, embodiments of the present invention provide a display luminance control method suitable for a display luminance control apparatus, which may be integrated in an electronic device.
The electronic device may be a terminal or other devices, including but not limited to a mobile terminal, for example, a mobile terminal including but not limited to a smartphone, a smart watch, a tablet computer, a notebook computer, a smart car, and the like.
The display brightness control method of the embodiment of the invention can be realized by a server, and can also be realized by a terminal and the server together.
The method for realizing the display brightness control by the terminal is taken as an example and is explained below.
As shown in fig. 1, the display brightness control system according to the embodiment of the present invention includes a terminal 10. The terminal 10 may be configured to receive a display brightness adjustment instruction from the distance sensor when the display brightness of the terminal is not at the maximum brightness, and detect a screen display state of each application in the terminal in response to the display brightness adjustment instruction.
When at least one application program in each application program is in a screen display state, the terminal 10 may be configured to determine whether the display brightness adjustment instruction is valid based on the terminal motion data of the acceleration sensor, and if the display brightness adjustment instruction is valid, adjust the display brightness of the terminal based on the display brightness adjustment instruction.
In the embodiment of the present invention, the distance sensor and the acceleration sensor may be provided in the terminal 10, or the distance sensor and the acceleration sensor may move in synchronization with the terminal 10 and transmit the collected data to the terminal 10.
For example, the distance sensor and the acceleration sensor may be connected to the terminal 10 in a wired or wireless manner, which is not limited by the embodiment of the present invention.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Embodiments of the present invention will be described from the perspective of a display luminance control apparatus, which may be specifically integrated in a server or a terminal.
As shown in fig. 2, a specific flow of the display brightness control method of the present embodiment may be as follows:
201. and when the display brightness of the terminal is not at the maximum brightness, receiving a display brightness adjusting instruction of the distance sensor.
For example, when a user uses the terminal to conduct a call, if the user brings the terminal close to the ear, the display brightness of the terminal is generally gradually reduced, for example, the terminal may adjust the display brightness to a screen-off state.
Alternatively, when the terminal is distant from the face of the user, the display brightness of the terminal may be reduced. For example, when the user holds the terminal in his hand and naturally swings with the hand while walking, the terminal may decrease the display brightness when the user is not using the terminal.
The distance sensor (P-sensor) may be configured to sense a distance between the distance sensor and an object to perform a predetermined function, for example, in an embodiment of the present invention, the distance sensor may be configured to sense a movement of the terminal to issue a brightness adjustment command.
And when the distance sensor detects that the terminal moves, a display brightness adjusting instruction can be sent out. For example, a user using a call function places the terminal far from the ear, or the user places the terminal close to the face, or the like.
202. And responding to the display brightness adjusting instruction, and detecting the screen display state of each application program in the terminal.
For example, applications with different functions may be installed in the terminal. Specifically, the screen display state of the application program refers to whether an element is displayed on the screen currently or not, and if the element is displayed on the screen, the application program is in the screen display state; if no elements of the application are displayed on the screen, the application is not in the screen display state.
Generally, the lowest display brightness of the terminal is the brightness corresponding to the screen-off state. The step of receiving the display brightness adjustment instruction of the distance sensor when the display brightness of the terminal is not at the maximum brightness may specifically include:
and when the display brightness of the terminal is the lowest brightness, receiving a display brightness adjusting instruction of the distance sensor.
Step 202 may specifically include:
and responding to the display brightness adjusting instruction, and detecting the screen display state of the call application in the terminal, wherein when the call application is not in the call state, the call application is in the screen display state.
For example, when a user makes a call using a call application on a terminal, a page of the call application is displayed on a screen. When the user brings the terminal page close to the ear, the terminal can be in a screen-off state; when the distance sensor detects that the distance between the terminal and the ear is increased, a display brightness adjusting instruction can be sent out.
At this time, the terminal may detect whether the call application is in the screen display state according to the display brightness adjustment instruction.
203. And when at least one application program in each application program is in a screen display state, judging whether the display brightness adjusting instruction is effective or not based on the terminal motion data of the acceleration sensor.
It is understood that the terminal may only have one application in the screen display state, or the terminal may support at least two applications in the screen display state at the same time, for example, the applications may be displayed on the screen at the same time by splitting the screen.
Among them, an acceleration sensor (G-sensor) is a sensor capable of measuring acceleration. Common acceleration sensors include capacitive, inductive, strain, piezoresistive, piezoelectric, and the like. The embodiment of the present invention does not limit the specific type of the acceleration sensor.
The terminal motion data is data obtained by measuring the motion of the terminal, and may represent a relevant parameter in the terminal motion process.
Specifically, the acceleration sensor may complete the determination of whether the display brightness adjustment command is valid through the logic diagram shown in fig. 3. In some optional embodiments, the terminal motion data includes terminal acceleration data and terminal angle data, and the step "determining whether the display brightness adjustment instruction is valid based on the terminal motion data of the acceleration sensor" may specifically include:
calculating an acceleration change value of the terminal at a target time based on the terminal acceleration data of an acceleration sensor;
calculating an angle change value of the terminal at the target time based on the terminal angle data of the acceleration sensor;
determining whether the terminal moves relative to a target position or not according to the acceleration change value and the angle change value;
and when the terminal is determined to move relatively to the target position, judging that the display brightness adjusting instruction is effective.
Wherein, the target time refers to a certain time period. For example, the target time may be the time between the time the user answers or makes a call and the time the user hangs up the call.
The target position may be a position pre-specified by the user or default by the terminal, such as the face of the user or the ear of the user, and so on. Alternatively, the target location may be the location at which the terminal is located at the beginning of the target time, and so on.
It can be understood that, in order to prevent the motion of the human body from making the acceleration sensor mistaken the motion of the mobile phone leaving the ear during the call, in the embodiment of the present invention, a misjudgment adjustment mechanism is added, and the step "determining whether the terminal moves relative to the target position according to the acceleration change value and the angle change value" includes:
calculating an acceleration change absolute value of the acceleration change value according to the acceleration change value, and calculating an angle change absolute value of the angle change value according to the angle change value;
judging the motion of the terminal based on the absolute value of the acceleration change;
and when the terminal is judged through the motion, the absolute value of the acceleration change of the terminal is greater than a preset acceleration change threshold, and the absolute value of the angle change is greater than a preset angular velocity change threshold, the terminal moves relative to the target position.
Specifically, as shown in fig. 4, the acceleration sensor may determine whether the terminal moves according to an absolute value of a change in acceleration.
In some optional examples, the acceleration change value includes an X-axis acceleration change value, a Y-axis acceleration change value, and a Z-axis acceleration change value, and the step "calculating an absolute value of acceleration change of the acceleration change value according to the acceleration change value" may specifically include:
calculating an absolute value of the change of the acceleration of the X axis, an absolute value of the change of the acceleration of the Y axis and an absolute value of the change of the acceleration of the Z axis according to the change value of the acceleration of the X axis, the change value of the acceleration of the Y axis and the change value of the acceleration of the Z axis;
the judging the motion of the terminal based on the absolute value of the acceleration change comprises the following steps:
when the absolute value of the change of the acceleration of the X axis, the absolute value of the change of the acceleration of the Y axis and the absolute value of the change of the acceleration of the Z axis are all larger than a preset judgment threshold value, the terminal judges through motion;
and when at least one of the absolute value of the change of the acceleration of the X axis, the absolute value of the change of the acceleration of the Y axis and the absolute value of the change of the acceleration of the Z axis is not more than a preset judgment threshold value, the terminal fails to be judged through movement.
Generally, as shown in fig. 4, when the absolute value of the change in the acceleration of the X axis, the absolute value of the change in the acceleration of the Y axis, and the absolute value of the change in the acceleration of the Z axis are all larger than the determination threshold, it is considered that the change in the acceleration of the terminal is large.
Further, the display brightness control method provided by the embodiment of the present invention may further include: when the terminal does not pass the motion judgment, the terminal does not move relative to the target position; alternatively, the first and second electrodes may be,
when the terminal passes the motion judgment, the absolute value of the acceleration change of the terminal is greater than a preset acceleration change threshold, and the absolute value of the angle change is not greater than a preset angular velocity change threshold, the terminal does not move relative to the target position; alternatively, the first and second electrodes may be,
and when the terminal passes the motion judgment, the absolute value of the acceleration change of the terminal is not greater than a preset acceleration change threshold, and the absolute value of the angle change is greater than a preset angular velocity change threshold, the terminal does not move relative to the target position.
That is, the terminal may be considered to be motionless (defined as a stationary state) if the acceleration of the terminal is unchanged or the absolute value of the change is not greater than the preset acceleration change threshold. At the moment, the terminal does not move relatively to the target position, and the display brightness adjustment instruction is invalid;
when a user holds the terminal to walk, the acceleration change is large, and the angle change is small. At the moment, the terminal does not move relatively to the target position, and the display brightness adjustment instruction is invalid;
when the user holds the terminal to turn, the acceleration change is small, and the angle change is large. At the moment, the terminal does not move relatively relative to the target position, and the display brightness adjusting instruction is invalid;
when the acceleration change of the terminal is large, the angle change is also large. At this time, the terminal moves relatively to the target position, and the display brightness adjustment instruction takes effect.
In some optional embodiments, as shown in fig. 5, when the acceleration change is large, the relative change angle between the mobile phone and the human body may also be determined according to the change amount Δ Pitch of the mobile phone and the change amount Δ Roll of the Roll angle of the mobile phone. At this time, the angle change value includes a pitch angle change value and a roll angle change value;
the calculating an absolute value of the angle change value according to the angle change value includes:
calculating a pitch angle change absolute value and a roll angle change absolute value according to the pitch angle change value and the roll angle change value;
when the terminal judges through the motion, the absolute value of the acceleration change of the terminal is greater than a preset acceleration change threshold, and the absolute value of the angle change is greater than a preset angular velocity change threshold, the terminal moves relative to the target position, and the method comprises the following steps:
and when the terminal judges through the movement, the absolute value of the acceleration change of the terminal is greater than a preset acceleration change threshold, and the absolute value of the pitch angle change and the absolute value of the roll angle change are greater than a preset angular speed change threshold, the terminal moves relative to the target position.
204. And if the display brightness adjusting instruction is effective, adjusting the display brightness of the terminal based on the display brightness adjusting instruction.
Specifically, the display brightness adjustment instruction may instruct the terminal to adjust the display brightness to a preset brightness value, or the display brightness adjustment instruction may instruct the terminal to increase the display brightness, but the specifically adjusted brightness value may be determined by the terminal itself.
For example, the terminal may determine a target value to which the display brightness needs to be adjusted according to the ambient brightness. Alternatively, the terminal may calculate a difference between the luminance value indicated by the display luminance adjustment instruction and the current luminance value, and may not adjust the display luminance of the terminal when the difference is smaller than a preset luminance difference threshold, and the like.
As shown in fig. 6, if the display brightness adjustment instruction is invalid, the terminal may not adjust the display brightness.
As can be seen from the above, in the embodiment of the present invention, when the display brightness of the terminal is not at the maximum brightness, the display brightness adjustment instruction of the distance sensor is received, the screen display state of each application program in the terminal is detected in response to the display brightness adjustment instruction, when at least one application program exists in each application program and is in the screen display state, whether the display brightness adjustment instruction is valid is determined based on the terminal motion data of the acceleration sensor, and if the display brightness adjustment instruction is valid, the display brightness of the terminal is adjusted based on the display brightness adjustment instruction; in the embodiment of the invention, on the basis of the distance sensor, the acceleration sensor is combined to judge whether the display brightness adjusting instruction sent by the final distance sensor is effective or not, so that the control on the display brightness of the terminal screen can be realized, the convenience of controlling the display brightness of the terminal is improved, and the misjudgment rate is reduced.
