[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0050] Embodiments of the present invention provide a display brightness control method, device, electronic device, and computer-readable storage medium. Specifically, embodiments of the present invention provide a display brightness control method applicable to a display brightness control device, and the display brightness control device can be integrated in an electronic device.

[0051] The electronic device may be a terminal or other device, including but not limited to a mobile terminal, such as a mobile terminal including but not limited to a smart phone, a smart watch, a tablet computer, a laptop computer, a smart car, etc.

[0052] The display brightness control method of the embodiment of the present invention may be implemented by a server, or may be implemented by a terminal and a server together.

[0053] The method is described below by taking a terminal implementing the display brightness control method as an example.

[0054] like Figure 1 As shown, the display brightness control system provided by the embodiment of the present invention includes a terminal 10. The terminal 10 can be used to receive a display brightness adjustment instruction from a distance sensor when the display brightness of the terminal is not at the maximum brightness, and detect the screen display status of each application in the terminal in response to the display brightness adjustment instruction.

[0055] When at least one of the applications is in screen display state, the terminal 10 can be used to determine whether the display brightness adjustment instruction is valid based on the terminal motion data of the acceleration sensor. If the display brightness adjustment instruction is valid, the display brightness of the terminal is adjusted based on the display brightness adjustment instruction.

[0056] In the embodiment of the present invention, the distance sensor and the acceleration sensor may be arranged in the terminal 10 , or the distance sensor and the acceleration sensor may move synchronously with the terminal 10 and send the collected data to the terminal 10 .

[0057] 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 in the embodiment of the present invention.

[0058] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0059] The embodiment of the present invention will be described from the perspective of a display brightness control device, which can be specifically integrated in a server or a terminal.

[0060] like Figure 2 As shown, the specific process of the display brightness control method of this embodiment can be as follows:

[0061] 201. When the display brightness of the terminal is not at the maximum brightness, receive a display brightness adjustment instruction from a distance sensor.

[0062] For example, when a user uses a terminal to make a call, if the user brings the terminal close to the ear, the display brightness of the terminal will generally decrease gradually. For example, the terminal can adjust the display brightness to a screen-off state.

[0063] Alternatively, when the terminal is far from the user's face, the display brightness of the terminal can be reduced. For example, when the user is walking, the terminal is held in the hand and follows the natural swing of the hand. At this time, the user is not using the terminal, and the terminal can reduce the display brightness.

[0064] Among them, the distance sensor (P-sensor) can be used to sense the distance between it and an object to complete a preset function. For example, in an embodiment of the present invention, the distance sensor can be used to sense the movement of the terminal to issue a brightness adjustment instruction.

[0065] When the distance sensor detects that the terminal is moving, a display brightness adjustment instruction may be issued, for example, when a user using the call function moves the terminal away from the ear, or when the user moves the terminal close to the face, etc.

[0066] 202. In response to the display brightness adjustment instruction, detect the screen display status of each application in the terminal.

[0067] For example, applications with different functions may be installed in the terminal. Specifically, the screen display state of the application refers to whether the application currently has elements displayed on the screen. If the application has elements displayed on the screen, the application is in the screen display state; if the application does not have elements displayed on the screen, the application is not in the screen display state.

[0068] Generally speaking, the lowest display brightness of the terminal is the brightness corresponding to the screen-off state. The step of "when the display brightness of the terminal is not at the maximum brightness, receiving the display brightness adjustment instruction of the distance sensor" may specifically include:

[0069] When the display brightness of the terminal is at the lowest brightness, a display brightness adjustment instruction of the distance sensor is received.

[0070] Step 202 may specifically include:

[0071] In response to the display brightness adjustment instruction, the screen display state of the call application in the terminal is detected, wherein when the call application is not in a call state, the call application is in a screen display state.

[0072] For example, when a user uses a call application on a terminal to make a call, the page of the call application will be displayed on the 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 becomes larger, a display brightness adjustment instruction can be issued.

[0073] At this time, the terminal can detect whether the call application is in the screen display state according to the display brightness adjustment instruction.

[0074] 203. When at least one of the applications is in a screen display state, determine whether the display brightness adjustment instruction is valid based on terminal motion data of an acceleration sensor.

[0075] It is understandable that the terminal may have only one application in the screen display state, or the terminal may also support at least two applications in the screen display state at the same time, for example, the applications may be displayed on the screen simultaneously by splitting the screen.

[0076] Among them, an acceleration sensor (G-sensor) is a sensor that can measure acceleration. Common acceleration sensors include capacitive, inductive, strain, piezoresistive, piezoelectric, etc. The embodiment of the present invention does not limit the specific type of the acceleration sensor.

[0077] The terminal motion data is data obtained by measuring the motion of the terminal, and can represent relevant parameters during the terminal motion process.

[0078] Specifically, the acceleration sensor can be Figure 3 The logic diagram shown completes the judgment on whether the display brightness adjustment instruction is valid. In some optional embodiments, the terminal motion data includes terminal acceleration data and terminal angle data, and the step of "judging whether the display brightness adjustment instruction is valid based on the terminal motion data of the acceleration sensor" may specifically include:

[0079] Calculating the acceleration change value of the terminal at the target time based on the terminal acceleration data of the acceleration sensor;

[0080] Calculating the angle change value of the terminal at the target time based on the terminal angle data of the acceleration sensor;

[0081] Determining whether the terminal moves relative to a target position according to the acceleration change value and the angle change value;

[0082] When it is determined that the terminal has moved relative to the target position, the display brightness adjustment instruction is determined to be valid.

[0083] The target time refers to a certain time period, for example, the target time may be the time between the time when the user answers or makes a call and the time when the user hangs up the call.

[0084] The target position may be a position pre-specified by the user or a default position of the terminal, such as the face of the user or the ear of the user, etc. Alternatively, the target position may also be the position of the terminal at the beginning of the target time, etc.

[0085] It is understandable that in order to prevent the acceleration sensor from mistaking the movement of the human body during a call as the movement of the mobile phone leaving the ear, a misjudgment adjustment mechanism is added in the embodiment of the present invention. The step of "determining whether the terminal moves relative to the target position according to the acceleration change value and the angle change value" includes:

[0086] Calculating an absolute value of an acceleration change of the acceleration change value according to the acceleration change value, and calculating an absolute value of an angle change of the angle change value according to the angle change value;

[0087] Based on the absolute value of the acceleration change, determining the movement of the terminal;

[0088] When the terminal passes the motion judgment, and the absolute value of the acceleration change of the terminal is greater than the preset acceleration change threshold, and the absolute value of the angle change is greater than the preset angular velocity change threshold, the terminal moves relative to the target position.

[0089] Specifically, you can Figure 4 As shown, the acceleration sensor can determine whether the terminal is moving by the absolute value of the acceleration change.

[0090] 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 of "calculating the acceleration change absolute value of the acceleration change value according to the acceleration change value" may specifically include:

[0091] Calculate the absolute value of the acceleration change on the X-axis, the Y-axis and the Z-axis according to the acceleration change on the X-axis, the Y-axis and the Z-axis;

[0092] The step of determining the movement of the terminal based on the absolute value of the acceleration change includes:

[0093] When the absolute value of the acceleration change on the X-axis, the absolute value of the acceleration change on the Y-axis, and the absolute value of the acceleration change on the Z-axis are all greater than a preset judgment threshold, the terminal makes a motion judgment;

[0094] When at least one of the absolute value of the X-axis acceleration change, the absolute value of the Y-axis acceleration change, and the absolute value of the Z-axis acceleration change is not greater than a preset judgment threshold, the terminal fails the motion judgment.

[0095] Generally speaking, if Figure 4 As shown, when the absolute value of the acceleration change on the X-axis, the Y-axis, and the Z-axis are all greater than the judgment threshold, it can be considered that the acceleration change of the terminal is large.

[0096] Furthermore, the display brightness control method provided by the embodiment of the present invention may further include: when the terminal fails to pass the motion judgment, the terminal does not move relative to the target position; or,

[0097] When the terminal passes the motion judgment, and the absolute value of the acceleration change of the terminal is greater than the preset acceleration change threshold, and the absolute value of the angle change is not greater than the preset angular velocity change threshold, then the terminal does not move relative to the target position; or,

[0098] When the terminal passes the motion judgment, and the absolute value of the acceleration change of the terminal is not greater than the preset acceleration change threshold, and the absolute value of the angle change is greater than the preset angular velocity change threshold, the terminal does not move relative to the target position.

[0099] In other words, if the terminal's acceleration does not change or the absolute value of the change is not greater than the preset acceleration change threshold, it can be considered that the terminal is not moving (defined as static state). At this time, the terminal has no relative motion relative to the target position, and the display brightness adjustment command is invalid;

[0100] When the user walks with the terminal in hand, the acceleration changes greatly and the angle changes slightly. At this time, the terminal does not move relative to the target position, and the display brightness adjustment command is invalid;

[0101] When the user turns around while holding the terminal, the acceleration changes slightly but the angle changes significantly. At this time, the terminal does not move relative to the target position, and the display brightness adjustment command is invalid.

[0102] When the terminal's acceleration changes greatly, the angle changes greatly. At this time, the terminal moves relative to the target position, and the display brightness adjustment command takes effect.

[0103] In some optional embodiments, such as Figure 5 As shown, when the acceleration changes greatly, the relative change angle between the phone and the human body can also be determined by the change in the phone's pitch angle △Pitch and the change in the phone's roll angle △Roll. At this time, the angle change value includes the pitch angle change value and the roll angle change value;

[0104] The step of calculating the angle change absolute value of the angle change value according to the angle change value comprises:

[0105] Calculating an absolute value of a pitch angle change and an absolute value of a roll angle change according to the pitch angle change value and the roll angle change value;

[0106] When the terminal passes the motion judgment, and 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, then the terminal moves relative to the target position, including:

[0107] When the terminal passes the motion judgment, and the absolute value of the acceleration change of the terminal is greater than the 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 the preset angular velocity change threshold, the terminal moves relative to the target position.

[0108] 204. If the display brightness adjustment instruction is valid, adjust the display brightness of the terminal based on the display brightness adjustment instruction.

[0109] 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 only instruct the terminal to increase the display brightness, but the specific adjusted brightness value may be determined by the terminal itself.

[0110] For example, the terminal may determine the target value to which the display brightness needs to be adjusted based on the ambient brightness. Alternatively, the terminal may calculate the difference between the brightness value indicated by the display brightness adjustment instruction and the current brightness value, and when the difference is less than a preset brightness difference threshold, the display brightness of the terminal may not be adjusted, and so on.

[0111] like Figure 6 As shown, if the display brightness adjustment instruction is invalid, the terminal may not adjust the display brightness.

[0112] From the above, it can be seen that the embodiment of the present invention can receive a display brightness adjustment instruction from a distance sensor when the display brightness of the terminal is not at the maximum brightness, detect the screen display status of each application in the terminal in response to the display brightness adjustment instruction, and when at least one application among the applications is in the screen display state, determine whether the display brightness adjustment instruction is valid based on the terminal motion data of the acceleration sensor; 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, since the display brightness adjustment instruction issued by the terminal distance sensor is determined to be valid based on the acceleration sensor on the basis of the distance sensor, it is possible to control the display brightness of the terminal screen, improve the convenience of controlling the display brightness of the terminal, and reduce the misjudgment rate.

[0113] In order to better implement the above method, accordingly, an embodiment of the present invention further provides a display brightness control device.

[0125] Based on the absolute value of the acceleration change, determining the movement of the terminal;

[0126] When the terminal passes the motion judgment, and the absolute value of the acceleration change of the terminal is greater than the preset acceleration change threshold, and the absolute value of the angle change is greater than the preset angular velocity change threshold, the terminal moves relative to the target position.

[0129] When the absolute value of the acceleration change on the X-axis, the absolute value of the acceleration change on the Y-axis, and the absolute value of the acceleration change on the Z-axis are all greater than a preset judgment threshold, the terminal makes a motion judgment;

[0130] When at least one of the absolute value of the X-axis acceleration change, the absolute value of the Y-axis acceleration change, and the absolute value of the Z-axis acceleration change is not greater than a preset judgment threshold, the terminal fails the motion judgment.

[0131] Optional, such as Figure 8As shown, the display brightness control device provided by the embodiment of the present invention further includes a motion judgment unit 705, which is used for determining that when the terminal fails to pass the motion judgment, the terminal does not move relative to the target position; or,

[0132] When the terminal passes the motion judgment, and the absolute value of the acceleration change of the terminal is greater than the preset acceleration change threshold, and the absolute value of the angle change is not greater than the preset angular velocity change threshold, then the terminal does not move relative to the target position; or,

[0133] When the terminal passes the motion judgment, and the absolute value of the acceleration change of the terminal is not greater than the preset acceleration change threshold, and the absolute value of the angle change is greater than the preset angular velocity change threshold, the terminal does not move relative to the target position.

[0134] Optionally, the angle change value includes a pitch angle change value and a roll angle change value;

[0135] The instruction validity judgment unit 703 is used to calculate the pitch angle change absolute value and the roll angle change absolute value according to the pitch angle change value and the roll angle change value;
