Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
FIG. 1 is a flow chart illustrating a method of screen brightness adjustment according to an exemplary embodiment; the method of the embodiment can be applied to an electronic device (e.g., a smart tv, a display of a desktop computer, etc.) having at least two light sensors, where the at least two light sensors are located on different frames of the electronic device.
As shown in FIG. 1, the method includes the following steps S11-S13:
in step S11, at least two ambient luminances detected by the at least two light sensors are obtained.
In this embodiment, the electronic device may acquire the at least two ambient luminances detected by the at least two light sensors when a set condition is satisfied. The setting condition may include receiving an instruction for opening a screen of the electronic device, or receiving an instruction for adjusting screen brightness of the electronic device, or detecting that brightness of an environment where the electronic device is located changes, and the like.
Taking the setting condition including receiving an instruction for opening the screen of the electronic device as an example, when the user wants to watch a program through the electronic device, the user may send the instruction for opening the screen of the electronic device to the electronic device through a remote control device of the electronic device, and then when the electronic device receives the instruction, the at least two ambient luminances detected by the at least two light sensors may be obtained.
In step S12, an application scene where the electronic device is currently located is determined based on the at least two ambient luminances.
In this embodiment, after obtaining at least two ambient luminances detected by the at least two light sensors, an application scene where the electronic device is currently located may be determined based on the at least two ambient luminances.
It should be noted that, the at least two light sensors are disposed on different frames of the electronic device to detect the ambient brightness of the electronic device in different directions. And when the electronic device is in different application scenes, the ambient brightness detected by the at least two light sensors is also different, so that the application scene where the electronic device is currently located can be determined by processing the at least two ambient brightness detected by the at least two light sensors.
In an embodiment, the manner of determining the application scene where the electronic device is currently located based on the at least two ambient luminances may be referred to the following embodiment shown in fig. 2, and will not be described in detail herein.
In step S13, the current screen brightness of the electronic device is adjusted based on the application scene.
In this embodiment, after determining the application scene where the electronic device is currently located based on the at least two ambient luminances, the current screen luminance of the electronic device may be adjusted based on the application scene.
For example, screen brightness adjustment strategies in different application scenes may be preset, and then after the application scene where the electronic device is currently located is determined, the current screen brightness of the electronic device is adjusted based on the screen brightness adjustment strategy matched with the application scene.
In an embodiment, the manner of adjusting the current screen brightness of the electronic device based on the application scene may also be referred to the following embodiments shown in fig. 3 or fig. 6, which will not be described in detail herein.
As can be seen from the above description, in the method of this embodiment, by obtaining at least two ambient luminances detected by the at least two light sensors, determining the application scene where the electronic device is currently located based on the at least two ambient luminances, and then adjusting the current screen luminance of the electronic device based on the application scene, it can be achieved that the application scene where the electronic device is currently located is accurately determined based on the detection data of the at least two light sensors on the electronic device, and then the current screen luminance of the electronic device is accurately adjusted based on the application scene, and it can be achieved that the screen luminance of the electronic device is automatically adjusted, and it is not necessary for a user to manually adjust the screen luminance, and it is possible to improve the intelligence level of the electronic device, meet the needs of the user, and improve the experience of the user.
FIG. 2 is a flow diagram illustrating how an application scenario in which the electronic device is currently located is determined in accordance with an illustrative embodiment; the present embodiment is exemplarily illustrated on the basis of the above embodiments by taking an example of how to determine the application scenario where the electronic device is currently located.
In this embodiment, the at least two light sensors of the electronic device may include a first light sensor located on a top frame of the electronic device and a second light sensor located on a side frame of the electronic device, where the first light sensor is configured to detect a first ambient brightness, and the second light sensor is configured to detect a second ambient brightness.
Specifically, the first light sensor may be disposed on a top frame of the electronic device, so as to detect a first ambient brightness of an environment above the electronic device; the second light sensor may be disposed on a side frame of the electronic device, so as to detect a second ambient brightness of a side environment of the electronic device.
On this basis, as shown in fig. 2, the determining the application scene where the electronic device is currently located based on the at least two ambient luminances in the above step S12 may include the following steps S21-S22:
in step S21, a difference between the first ambient brightness and the second ambient brightness is determined.
In this embodiment, after the electronic device receives an instruction for opening a screen of the electronic device, a first ambient brightness detected by the first light sensor and a second ambient brightness detected by the second light sensor may be obtained, and then a difference between the first ambient brightness and the second ambient brightness may be calculated.
In step S22, an application scenario in which the electronic device is currently located is determined based on the difference.
In this embodiment, after determining the difference between the first ambient brightness and the second ambient brightness, the application scene where the electronic device is currently located may be determined based on the difference.
It should be noted that, because the first light sensor and the second light sensor are respectively disposed on the top frame and the side frame of the electronic device, when the electronic device is in different application scenes (e.g., a daytime scene, a scene in which a ceiling lamp is turned on at night, a desk lamp scene located beside the electronic device at night, etc.), the ambient brightness detected by the first light sensor and the second light sensor are different, so that the application scene where the electronic device is currently located can be determined by calculating a difference between the first ambient brightness and the second ambient brightness detected by the two light sensors.
In one case, the step S22 may further include:
and determining the application scene where the electronic equipment is currently located as a first application scene in response to the difference being greater than or equal to a first set threshold.
The first application scene may include a bright scene such as a ceiling lamp turned on in the daytime or at night.
It should be noted that the first setting threshold may be set based on actual service needs, which is not limited in this embodiment.
On this basis, as shown in fig. 3, the adjusting the current screen brightness of the electronic device based on the application scene in the above step S13 may include the following steps S31-S34:
in step S31, the brightness of the environment in which the terminal device associated with the electronic device is located is determined.
In this embodiment, after determining the application scene where the electronic device is currently located based on the at least two ambient luminances, when adjusting the current screen luminance of the electronic device using the application scene, the luminance of the environment where the terminal device associated with the electronic device is located may also be considered. Wherein, the brightness of the environment of the terminal device can be determined based on a light sensor arranged on the terminal device.
In step S32, a target ambient brightness is determined based on the first ambient brightness and the brightness of the environment in which the terminal device is located.
In an embodiment, after determining the brightness of the environment in which the terminal device associated with the electronic device is located, the target ambient brightness may be determined based on the first ambient brightness and the brightness of the environment in which the terminal device is located. For example, an average value of the first ambient brightness and the brightness of the environment where the terminal device is located may be calculated, and then the average value may be determined as the target ambient brightness for calculating the target screen brightness of the electronic device, so that the target ambient brightness according to which the current screen brightness of the electronic device is adjusted may be accurately determined based on the light sensors respectively disposed on the electronic device and the terminal device.
In step S33, a target screen brightness of the electronic device corresponding to the target ambient brightness is determined based on a pre-established correspondence between the target ambient brightness and the screen brightness in the first application scene.
In this embodiment, after determining that the application scene where the electronic device is currently located is a first application scene (for example, a day scene or a scene where a ceiling lamp is turned on at night), a pre-established correspondence between the target ambient brightness and the screen brightness in the first application scene may be obtained, and then the target screen brightness of the electronic device may be determined based on the correspondence and the first ambient brightness.
It should be noted that, in the embodiment, the first ambient brightness detected by the first light sensor is used to determine the target screen brightness of the electronic device, the reason why the target screen brightness of the electronic device is determined by using the second ambient brightness detected by the second light sensor is that, in the first application scenario, the first ambient brightness detected by the first light sensor on the top frame of the electronic device is much greater than the second ambient brightness detected by the second light sensor on the side frame of the electronic device (it can be understood that, in order to ensure that the first ambient brightness is much greater than the second ambient brightness, the first setting threshold may be set to be relatively large, such as 500nit, etc., which is not limited in this embodiment), in the first application scene, the first light sensor can detect the light in the current environment more obviously, the target screen brightness of the electronic device can be more accurately determined based on the first ambient brightness.
The target screen brightness can be understood as ideal screen brightness or proper screen brightness of the electronic device.
In step S34, the current screen brightness of the electronic device is adjusted to the target screen brightness.
In this embodiment, after determining the target screen brightness of the electronic device corresponding to the target ambient brightness based on the pre-established correspondence between the target ambient brightness and the screen brightness in the first application scene, the current screen brightness of the electronic device may be adjusted to the target screen brightness.
In one embodiment, FIG. 4 is a flow chart illustrating how to determine the brightness of the environment in which a terminal device associated with the electronic device is located, according to an example embodiment. As shown in fig. 4, the determining the brightness of the environment where the terminal device associated with the electronic device is located in the step S31 may further include the following steps S41-S42:
in step S41, a third ambient brightness detected by a third light sensor and a fourth ambient brightness detected by a fourth light sensor preset in the terminal device are obtained.
The terminal device is associated with the electronic device, the third light sensor is located on the front side of the terminal device (i.e., used for detecting the ambient brightness of the front side of the terminal device), and the fourth light sensor is located on the back side of the terminal device (i.e., used for detecting the ambient brightness of the back side of the terminal device).
For example, the terminal device associated with the electronic device may be a device provided with an application program for controlling the electronic device. That is, the above-described terminal device associated with the electronic device may be used to control the electronic device in place of the remote control of the electronic device.
In step S42, the brightness of the environment in which the terminal device is located is determined based on the third ambient brightness and the fourth ambient brightness.
It should be noted that, in this embodiment, it is considered that the terminal device such as a smart phone is generally closer to the user, that is, generally located near the user, so that the brightness of the environment where the terminal device is located is determined based on the third ambient brightness and the fourth ambient brightness, and the ambient brightness around the user is estimated according to the brightness of the environment where the terminal device is located, so that the target screen brightness of the electronic device can be determined based on the brightness of the environment where the terminal device is located and the ambient brightness detected by at least two light sensors of the electronic device.
In another embodiment, the terminal device may further include an acceleration sensor, and the step S42 may further include the following steps S51-S53:
in step S51, the current posture of the terminal device is determined based on acceleration data detected by the acceleration sensor.
In step S52, the current posture of the terminal device, the third ambient brightness, and the fourth ambient brightness are input to a pre-trained neural network model, so as to obtain an ambient brightness estimation result of the terminal device in a preset posture.
It can be understood that, under the condition that the lighting condition of the environment where the terminal device is located is not changed, if the terminal device is in different postures, the third ambient brightness detected by the third light sensor and the fourth ambient brightness detected by the fourth light sensor of the terminal device are also different. Therefore, in this embodiment, sample luminance data detected by the third light sensor and the fourth light sensor can be obtained in advance at different postures of the terminal device, and the neural network model is trained based on the different postures of the terminal device and the sample luminance data at the corresponding postures, so that after the current posture, the third ambient luminance and the fourth ambient luminance of the terminal device are obtained, the current posture, the third ambient luminance and the fourth ambient luminance of the terminal device are input into the neural network model, and an ambient luminance estimation result of the terminal device at the preset posture is obtained.
The preset gesture can be a gesture in which the screen of the terminal device is parallel to the screen of the electronic device.
It can be understood that when the screen of the terminal device is parallel to the screen of the electronic device, the ambient brightness detected by the light sensor of the terminal device can more accurately reflect the ambient brightness seen from the user perspective.
In step S53, the brightness of the environment where the terminal device is located is determined based on the environment brightness estimation result.
In this embodiment, after the environmental brightness estimation result of the terminal device in the preset posture is obtained, the brightness of the environment where the terminal device is located may be determined based on the environmental brightness estimation result. For example, the ambient brightness estimate may be determined to be the brightness of the environment in which the terminal device is located.
In another case, the step S22 may further include:
and determining the application scene where the electronic equipment is currently located as a second application scene in response to the difference value being smaller than a second set threshold value.
The second application scene may include a dim scene such as a desk lamp scene which is turned on at night and is located beside the electronic device.
It should be noted that the second set threshold may be set based on actual service requirements, for example, the second set threshold is set to be less than or equal to the first set threshold in the foregoing embodiment, which is not limited in this embodiment.
On this basis, as shown in fig. 6, the adjusting the current screen brightness of the electronic device based on the application scene in the above step S13 may include the following steps S61-S62:
in step S61, a brightness adjustment amount of the electronic device is determined based on a preset brightness adjustment ratio in the second application scene.
In this embodiment, after it is determined that the application scene where the electronic device is currently located is a second application scene (for example, a desk lamp scene located beside the electronic device is turned on at night), the preset brightness adjustment ratio in the second application scene may be obtained, and then the brightness adjustment amount of the electronic device may be determined based on the preset brightness adjustment ratio.
It should be noted that the preset brightness adjustment ratio may be set based on actual service needs, for example, 10% or 20%, which is not limited in this embodiment.
On the basis, after the preset brightness adjustment proportion is determined, the brightness adjustment amount of the electronic equipment can be determined based on the product of the preset brightness adjustment proportion and the current screen brightness of the electronic equipment.
In step S62, the current screen brightness of the electronic device is adjusted based on the brightness adjustment amount.
In this embodiment, after the brightness adjustment amount of the electronic device is determined based on the preset brightness adjustment ratio in the second application scene, the current screen brightness of the electronic device may be adjusted based on the brightness adjustment amount. For example, the current screen brightness of the electronic device may be adjusted downward based on the brightness adjustment amount, i.e., the current screen brightness of the electronic device is decreased by the brightness adjustment amount.
In an embodiment, after the operation of adjusting the current screen brightness of the electronic device based on the application scene in step S13 is performed, the corresponding relationship data between the application scene and the current screen brightness may be recorded, and further, when the electronic device is turned on next time and detects the same application scene, the current screen brightness of the electronic device may be directly adjusted based on the recorded data, so that a process of determining the target screen brightness of the terminal device is omitted, and the efficiency of adjusting the current screen brightness of the electronic device may be improved.
In another embodiment, within a set time after the operation of adjusting the current screen brightness of the electronic device based on the application scene in step S13 is performed, if the operation of manually adjusting the screen brightness by the user is detected, the screen brightness adjustment amount manually adjusted by the user may be further obtained, and further, when the electronic device is turned on next time and the same application scene is detected, the adjustment amount may be superimposed on the default screen brightness corresponding to the application scene. It should be noted that the "superimposition" here may actually be "up-adjustment" or "down-adjustment", and the specific situation may depend on the manual adjustment manner of the user, that is, it may be seen that the user has manually up-adjusted or manually down-adjusted the screen brightness before. Therefore, the finally adjusted screen brightness of the electronic equipment can be ensured to better meet the personalized requirements of users.
