Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
A terminal screen control method, apparatus, terminal device, and computer-readable storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.
It should be noted that the terminal screen control method in the embodiment of the present application can be applied to the terminal screen control device in the embodiment of the present application. The terminal screen control device can be configured on the terminal equipment. The terminal device may be a mobile terminal, such as a mobile phone, a tablet computer, a personal digital assistant, and other hardware devices with various operating systems.
As shown in fig. 1, the terminal screen control method according to the embodiment of the present application may be used to determine whether a user is reading the terminal device a by detecting a visual angle range of eyes of the user when the user uses the terminal device a, and control the screen of the terminal to be turned off or kept on according to a detection result.
In order to realize the intelligent control of the on-off of the terminal screen and achieve the purpose of saving the electric quantity of the terminal while meeting the intelligent requirement of the on-off of the terminal screen, the embodiment of the application provides a terminal screen control method. As shown in fig. 2, the terminal screen control method may include:
s210, when the screen of the terminal is in a bright screen state, triggering the stability detection component to detect whether the terminal is in a stable state.
Optionally, when it is monitored that the screen of the terminal device is in a bright screen state, a stability detection component in the terminal device may be triggered to detect whether the terminal device is in a stable state. The terminal is in a stable state, which means that the terminal is in a stable state and does not greatly shake. It can be understood that when the user uses the terminal, the screen of the terminal can be lightened so as to be used by the user, in the screen lightening process, the user may not use the terminal any more or leave the position of the terminal, and when the screen of the terminal is in the lightening state, the stability detection component can be triggered to detect whether the terminal is in the stable state or not. In the embodiment of the present application, the stability detecting component may be a sensor capable of detecting a displacement state, such as a gyroscope or a vibration sensor. Two examples of different implementations will be given below:
as one example, the stability detection component includes a gyroscope. In this example, a specific implementation process of the trigger stability detection component detecting whether the terminal is in a stable state may be as follows: recording component values of an X axis, a Y axis and a Z axis of the gyroscope, judging whether the jitter amplitude of the gyroscope is stable according to the component values of the X axis, the Y axis and the Z axis, returning to execute the step of recording the component values of the X axis, the Y axis and the Z axis of the gyroscope in a preset time period when judging that the jitter amplitude of the gyroscope is not stable, and determining that the terminal is in a stable state when judging that the jitter amplitude of the gyroscope is stable.
Optionally, when the screen of the terminal is in a bright screen state, component values of an X axis, a Y axis, and a Z axis of the gyroscope in a preset time period may be recorded, and whether a change in an angular velocity measured by the gyroscope in the preset time period is smaller than a certain threshold value is determined according to the component values of the X axis, the Y axis, and the Z axis, if so, the jitter amplitude of the gyroscope is determined to be stable, at this time, the terminal may be determined to be in a stable state, otherwise, the jitter amplitude of the gyroscope is determined to be not stable, and at this time, the step of recording component values of the X axis, the Y axis, and the Z axis of the gyroscope in the preset time period may be performed.
That is to say, it may be detected whether the axis component values of the gyroscope recorded within the preset time period change, and when it is detected that the axis component values of the gyroscope recorded within the preset time period change greatly, it may be considered that the jitter amplitude of the gyroscope is not stable, for example, when a user is at an adjustment terminal, the gyroscope may be continuously triggered to record the axis component values of the gyroscope at this time; when detecting that the component values of each axis of the gyroscope recorded in the preset time period are not changed, the jitter amplitude of the gyroscope can be judged to be stable, and at the moment, the terminal can be considered to be in a stable state.
As another example, the stability detection component includes a vibration sensor. In this example, a specific implementation process of the trigger stability detection component detecting whether the terminal is in a stable state may be as follows: and receiving an output signal of a vibration sensor, and judging whether the terminal is in a stable state or not according to the output signal of the vibration sensor. Alternatively, the current movement displacement of the terminal may be detected by an output signal of the vibration sensor, and it is determined whether the terminal is in a stable state according to the movement displacement. For example, if the movement displacement detected by the vibration sensor is within a certain range, the terminal may be considered to be in a stable state.
Optionally, in an embodiment of the present application, when detecting that the terminal is not in a stable state, the stability detection component may be continuously triggered to detect whether the terminal is in the stable state.
And S220, when the terminal is detected to be in a stable state, calling a front camera of the terminal to shoot the current scene.
Optionally, when it is detected that the terminal is in a stable state, it may be considered that the terminal is not moved or shaken by the user, and at this time, a front camera of the terminal device may be called, and shooting is performed by using the front camera.
And S230, identifying the visual angle range of human eyes in the shot image.
Optionally, the face recognition technology is used for carrying out face recognition on the shot image to obtain a face region, the eye region is extracted from the face region based on the eye positioning algorithm, and iris sight analysis is carried out on the eye region to determine the visual angle range of the eyes in the image.
And S240, controlling the screen to be turned off or kept on according to the visual angle range of human eyes in the image.
Optionally, whether the user is currently using the terminal may be determined according to the visual angle range of the human eyes in the image, and if it is determined that the user is currently using the terminal, the terminal screen may be controlled to remain bright; if the terminal is judged not to be used by the user currently, for example, the terminal is horizontally placed on a desk, the terminal is in a stable state at the moment, but the terminal is not used by the user currently, and the screen of the terminal can be controlled to be turned off at the moment so as to achieve the purpose of saving the electric quantity of the terminal.
It can be understood that the visual angle range of the human eyes in the obtained image can be compared with the sample, and whether the screen of the terminal is controlled to be turned off or the screen of the terminal is controlled to be kept on according to the comparison result. As a possible implementation manner, acquiring a visual angle range of a sample human eye, wherein the visual angle range of the sample human eye is used for indicating a reference visual angle range of an eye when a user uses the terminal, performing similarity matching between the visual angle range of the human eye in the image and the visual angle range of the sample human eye, and controlling the terminal screen to keep bright when the similarity between the visual angle range of the human eye in the image and the visual angle range of the sample human eye is greater than or equal to a preset threshold value; and when the similarity between the visual angle range of the human eyes in the image and the visual angle range of the human eyes of the sample is smaller than the preset threshold value, controlling the screen to be turned off.
That is to say, similarity calculation can be performed on the visual angle range of human eyes in the obtained image and the visual angle range of human eyes of the sample, if the similarity between the visual angle range and the visual angle range of human eyes is greater than or equal to a preset threshold value, it can be considered that the current user is using the terminal device, and at the moment, the terminal screen can be controlled to keep bright; if the similarity is smaller than the preset threshold, the user can be considered not to use the terminal equipment currently, and the screen of the terminal screen can be controlled to be turned off at the moment.
It should be noted that, in the embodiment of the present application, the range of the viewing angle of the human eye may be generated in advance. As an example, as shown in fig. 3, the viewing angle range of the sample human eye may be generated in advance by:
s310, when the screen of the terminal is in a bright screen state and the terminal is in a stable state, calling a front camera of the terminal to shoot for multiple times;
s320, identifying the visual angle range of human eyes in the shot multiple sample images, and determining the visual angle range of the eyes of the user when the user uses the terminal from the visual angle range of the human eyes in the multiple sample images;
optionally, face recognition is performed on the plurality of shot images based on a face recognition technology to obtain a face region in each image, a human eye region is extracted from the face region based on a human eye positioning algorithm, and iris sight analysis is performed on the human eye region to determine the visual angle range of human eyes in each sample image. Then, the visual angle range of the eyes of the user when using the terminal can be determined from the visual angle range of the eyes in a plurality of sample images. For example, the visual angle ranges of human eyes in the multiple sample images can be used as the visual angle ranges of the sample human eyes, so that whether the current user uses the terminal device can be judged by judging whether the visual angle range of the human eyes in the currently acquired image is matched with one visual angle range in the visual angle ranges of the sample human eyes.
For another example, a viewing angle range with a high proportion of the viewing angle range of the human eye in the plurality of sample images may be selected as the viewing angle range of the human eye when the user uses the terminal (i.e., the viewing angle range of the human eye of the sample). For example, if there are 5 sample images, and the viewing angle ranges of human eyes in the 5 sample images are "30 degrees", "50 degrees" and "40 degrees", respectively, in this case, the viewing angle range corresponding to "30 degrees" with a high duty ratio can be taken as the viewing angle range of the eyes of the user when using the terminal from the viewing angle ranges of human eyes in the 5 sample images.
S330, taking the determined visual angle range of the eyes of the user when the user uses the terminal as the visual angle range of the sample human eyes.
That is to say, when the user uses the mobile phone, the bright screen is triggered, when the stability detection component detects that the terminal is in a stable state, the terminal holding posture is fixed well, at the moment, the visual angle range of human eyes is identified through multiple snapshot by the front camera, the playing habit of the user is determined, and one or more preset samples are selected as a reference standard, so that whether the user is using the terminal currently or not is judged according to the samples later.
According to the terminal screen control method, when the terminal screen is in the bright screen state, the stability detection assembly is triggered to detect whether the terminal is in the stable state or not, when the terminal is detected to be in the stable state, the front-facing camera of the terminal is called to shoot a current scene, then face recognition is carried out on the shot image to recognize the visual angle range of human eyes in the image, and the terminal screen is controlled to be turned off or kept bright according to the visual angle range of the human eyes in the image. When monitoring that the terminal is in a stable state, utilize face identification correlation technique, discern the visual angle range of user's eyes promptly to whether the user is using the terminal according to the visual angle range intelligent detection who discerns the eyes, and according to the bright going out of testing result intelligent control terminal screen, when satisfying the demand intelligent to terminal screen bright going out, also reached the purpose of saving the terminal electric quantity, promoted user's use and experienced.
In order to make the automatic screen-off of the terminal equipment more intelligent, the screen-off can be adjusted according to different application programs. Optionally, in an embodiment of the present application, when a similarity between a visual angle range of human eyes in the image and a visual angle range of human eyes in the sample is smaller than the preset threshold, determining an application program type to which an application interface currently being displayed on the terminal screen belongs, and when the application program type is a viewing class, controlling the terminal screen to be turned off; and when the type of the application program is an audio and video type, controlling the terminal screen to keep bright.
Optionally, when the similarity between the visual angle range of the human eyes in the image and the visual angle range of the human eyes in the sample is smaller than the preset threshold, it may be determined that the face of the user does not face the terminal screen, for example, the user is far away from the location of the terminal, it may be determined which application program in the terminal is running at the front end, and the type of the application program is determined, if the type of the application program is a browsing type, such as a book application program, a news application program, and the like, it may be determined that the user is away from the terminal and temporarily does not need to browse the APP, and at this time, the terminal screen may be controlled to be turned. If the application program type is an audio-video type, such as a video application program, an audio application program and the like, the user can be considered to leave the terminal and also want to continue listening to songs or listening to video sounds by using the application program, and at the moment, the screen of the terminal can be controlled to keep bright.
