In some embodiments, the display device itself comprises a camera, i.e. the camera is built into the display device, as shown in fig. 6 a.

In other embodiments, the display apparatus itself does not include a camera, i.e., the camera is connected to the controller 250 of the display apparatus through the external device interface 240 on the display apparatus, as shown in fig. 6 b.

In the embodiment of the application, the camera can be used as a detector and can be built in or externally connected to the display equipment. After the camera is started to run, image data can be acquired. The camera can be connected with the controller through the interface component, so that the collected image data is sent to the controller for processing.

The camera application refers to an application that needs to access the camera, such as a "magic mirror" application, a "hi" application, a "K song" application, and so on. The camera application may start the camera through a camera control service (camera service) in the system framework layer, for example, send a start instruction to the camera control service, and after the camera control service receives the start instruction, control the camera to be started. Because any camera application can start the camera, the situation that some applications start the camera without the knowledge of a user and privacy of the user is easily revealed can easily occur.

To solve the problem, the present application provides a display device in which the controller 250 is configured to: monitoring whether an application starting camera exists; when the fact that an application starts a camera is monitored, judging whether the application is a foreground application or a first preset application; if the application is a foreground application or a first preset application, allowing the application to start a camera; if the application is not a foreground application or a first predetermined application, the application is refused to start the camera.

In some embodiments, the controller generates a first application set in advance, where the first application set includes application information corresponding to a first predetermined application, and the first predetermined application is an application that allows the user to start the camera in the background. When the controller monitors that an application starts a camera, acquiring application information corresponding to the application, judging whether the application information corresponding to the application is consistent with application information of a foreground application, and judging whether the application information corresponding to the application is contained in a first application set; if the application information corresponding to the application is consistent with the application information of the foreground application, the application is the foreground application; if the application information corresponding to the application is contained in the first application set, the application is a first preset application. The application information corresponding to the application may include a package name and an application name of the application.

In some embodiments, the controller generates a second application set in advance, where the second application set includes application information corresponding to a second predetermined application, and the second predetermined application is an application that the user prohibits the background from starting the camera. When the application for starting the camera is not the first preset application or the foreground application, after rejecting the application to start the camera, the controller judges whether the application is the second preset application according to the application information of the application and the stored second application set, and if the application is not the second preset application, the controller displays warning information for prompting a user; and displaying a first control and a second control, wherein the first control is used for triggering setting the application as a first preset application, and the second control is used for triggering setting the application as a second preset application; if receiving user operation on the first control, adding application information corresponding to the application into a first application set; and if the user operation on the second control is received, adding the application information corresponding to the application into a second application set.

FIG. 7 is a user interface of the present application shown in some embodiments that includes both warning information, a first control, and a second control, i.e., a user interface that is displayed in response to determining that the application that launched the camera is not a second predetermined application. As shown in fig. 7, the warning message displayed on the interface is specifically "the current xx application is using the camera in the background, please confirm whether to know; if the application is active, the application can be clicked to be added into a white list, and the application is allowed by default when the application is used in the background later; if the user does not allow the user to click the prohibition, the application is prohibited from being used in the background later so as to prevent the user privacy from being obtained; the first control displayed is specifically a control named "allow", and the second control is specifically a control named "prohibit".

In some embodiments, all of the first predetermined applications may be presented in a visual application list in the user interface, with application names of the first predetermined applications being explicitly displayed in the list, so that the user may view all of the first predetermined applications in a centralized manner.

Fig. 8 (a) is a list of visual applications including a first predetermined application, shown in some embodiments of the application, including a "magic mirror" application, an "AI workout" application, and a "video call" application, which may open a camera in the background, as shown in fig. 8 (a). The user may set a new first predetermined application by operating the "add application" control, and may delete the set first predetermined application from the list by operating the "delete application" control.

In some embodiments, all of the second predefined applications may be presented in a visual application list in the user interface, where the application names of the second predefined applications are explicitly displayed, so that the user may view all of the second predefined applications in a centralized manner.

Fig. 8 (b) is a list of visual applications including a second predetermined application, shown in some embodiments of the application, including a "cloud audiovisual" application, a "fast-handed" application, and a "always-on" application, which are prohibited from opening the camera in the background, as shown in fig. 8 (b). The user may set a new second predetermined application by operating the "add application" control, and may delete the set second predetermined application from the list by operating the "delete application" control.

For example, when the "K song" application is running in the foreground, if it is monitored that the "magic mirror" application starts the camera through the camera control service, the "magic mirror" application may be determined to be the first predetermined application according to the stored first application set, so that the camera is started according to a start instruction sent by the "magic mirror" application. If the microblog application is monitored to start the camera through the camera control service, judging that the microblog application is not the first preset application according to the stored first application set, and ignoring a starting instruction sent by the microblog application, so that the camera is not started; according to the stored second application set, it can be judged that the microblog application is not the second predetermined application, so that a user interface containing warning information, the first control and the second control is displayed, as shown in fig. 7. If the cloud audio-visual application is monitored to start the camera through the camera control service, judging that the cloud audio-visual application is not the first preset application according to the stored first application set, and ignoring a starting instruction sent by the cloud audio-visual application, so that the camera is not started; according to the stored second application set, the cloud audio-visual application can be judged to be a second preset application, so that a user interface containing warning information, the first control and the second control does not need to be displayed.

In some embodiments, the visualization application list presenting the first predefined application and the visualization application list presenting the second predefined application may be contained in the same application list page, wherein the first predefined application and the second predefined application are marked as different states for the user to distinguish the first predefined application, the second predefined application, and other applications according to the display state of the applications.

FIG. 8 (c) is a visual application list of the present application showing all applications in some embodiments, as shown in FIG. 8 (c), the first predetermined application including a "magic mirror" application, an "AI exercise" application, and a "video call" application, which are marked as "allowed" states; the second predetermined applications include a "cloud audiovisual" application, a "fast-handed" application, and a "always-on" application, which are marked as "forbidden" states; other applications are marked as "unset" status, such as "microblog" applications, "head bar" applications, "encyclopedia" applications, and so forth.

In some embodiments, the user may add or subtract the first predetermined application and the second predetermined application in a "setup".

For example, the user may control the display device to display an interface including at least one application option, such as an interface including an application list including at least one application option, through one or more preset operations; when the user interface is displayed, a user can select a designated application option through a first user operation, set the designated application option as a first preset application, namely, the application information corresponding to the designated application is added to the first application set, and can select the designated application option through a second user operation, set the designated application option as a second preset application, namely, the application information corresponding to the designated application is added to the second application set. The first user operation and the second user operation may be one user operation or a series of user operations including a plurality of user operations.
