The angle at which the camera is located, such as its pitch angle in the vertical direction or its angle in the horizontal direction, is related to the field of view of the camera. The tripod head is a supporting device for mounting and fixing the camera, and is divided into a fixed tripod head and an electric tripod head, wherein the electric tripod head is suitable for large-range scanning and shooting, and the field range of the camera can be enlarged. The electric pan-tilt can be a horizontal rotating pan-tilt which can only rotate left and right, and also can be an omnibearing pan-tilt which can rotate left and right and can rotate up and down. Generally, two motors are installed in the omni-directional pan/tilt head, and are respectively used for driving the pan/tilt head to rotate in the horizontal direction and the vertical direction so as to change the angle of the camera. The camera mounted on the electric pan-tilt is also called pan-tilt camera.

As shown in fig. 2, the display device 200 comprises a detector 230, the detector 230 comprising a camera, which may be a pan-tilt-camera 231 as shown in fig. 6 a.

It should be noted that the cameras referred to in the following embodiments of the present application are all pan-tilt cameras unless otherwise specified.

In some embodiments, the user can control the rotation of the pan-tilt head by operating a designated key on the control device to adjust the angle of the camera. For example, the user may input a user operation for controlling the pan/tilt head to rotate left and right by operating the "left" and "right" direction keys on the control device. For another example, the user may input a user operation for controlling the pan/tilt head to rotate downward and upward by operating the "down" and "up" direction keys on the control device. After the display device receives the user operation for adjusting the angle of the camera as described above, the motor in the pan-tilt head is controlled to rotate to drive the pan-tilt head to rotate towards the target adjustment direction indicated by the user operation in response to the received user operation.

In some embodiments, after the camera is started, the controller automatically controls the camera to rotate to the initial angle which is saved in advance. In other words, the initial angle of the camera is the target angle to which the camera is rotated after being started. For example, the initial angle may be an angle input by the user according to the usage habit and the common requirement of the user, or may be a factory default initial angle, that is, a preset initial angle.

In order to bring convenience to users to adjust the initial angle of the camera to a satisfactory angle, the application provides a display device, wherein a setting interface provided by the display device comprises an item for adjusting the initial angle of the camera, when the user operates the item through an operation control device, the user responds to the operation of the user, the camera is started to enable the camera to start to collect images, a video playing window is started in the setting interface, and the images collected by the camera are displayed in the video playing window. Therefore, in the process of adjusting the initial angle of the camera, a user can preview an image picture acquired by the camera, and prompts and basis are provided for the adjustment operation of the user.

Fig. 7a to 7h are schematic diagrams illustrating an interaction process and an interface change for adjusting an initial angle of a camera according to an example of the present application. It should be understood that other embodiments of the present application can be obtained by those skilled in the art by adding or subtracting interactive steps based on the interactive processes shown in fig. 7a to 7h, and all of them belong to the protection scope of the present application.

Fig. 7a exemplarily shows a play screen provided by the display device. It should be appreciated that the play screen may be one or more of a user interface, a video screen, a picture screen, and the like. In the example shown in fig. 7a, the displayed play screen is a system homepage.

When the display displays a play screen as shown in fig. 7a, the user can input a menu item display instruction by operating the control device to instruct the display apparatus to present a setting menu on which a setting item corresponding to the camera is provided or an item higher in the hierarchy for triggering display of the setting item corresponding to the camera. When the display device controller receives a menu item display instruction input by a user, the display device controller controls the setting menu to be presented on the display. Illustratively, the user may enter a user instruction indicating that a setup menu is displayed by actuating a "menu" key on the control device, the controller may present on the display a user interface as shown in FIG. 7b in response to the user instruction, the user interface having a menu option page displayed therein containing a plurality of items 71-77 and a selector 78 indicating that any one of the items is selected, the user may move the position of the selector 78 in the user interface by operating the input of the control device to change the selection of a different item.

Next, in fig. 7b, when the user operates the control device to input a user instruction indicating that the selector selects the item 76, the controller may present a user interface as shown in fig. 7c in which a main setting menu page ("AI setting") 76 is displayed on the display in response to the user instruction, the main setting menu page 76 being a detailed menu option corresponding to the item 76, including items 761-.

Referring to fig. 7c, item 761 ("camera settings") is an exemplary camera corresponding master setting item. In fig. 7c, when the user operates the control device to input a user instruction indicating the selector selection item 761, the controller may present a user interface as shown in fig. 7d on the display in response to the user instruction, in which a menu page ("camera settings") 761 corresponding to the camera is displayed, the menu page 761 containing sub-setting items for controlling/adjusting the camera, i.e., items 7611 and 7613. It should be understood that the sub setting item corresponding to the camera is a setting item having a lower hierarchy with respect to the aforementioned main setting item.

The user interface shown in fig. 7d includes an item for adjusting the initial angle of the camera, i.e., item 7613 "initial angle of the camera", and the user can trigger the adjustment of the initial angle of the camera by operating the item. For example, in fig. 7d, when a user operates the control device to input a user instruction indicating a selector selection item 7613, the controller may present a user interface as shown in fig. 7e in which another menu page ("initial camera angle") 7613 corresponding to the camera is displayed on the display in response to the user instruction, the menu page including a sub-setting item "manual adjustment" for triggering manual adjustment of the initial camera angle, and a sub-setting item "smart adjustment" for triggering automatic adjustment of the initial camera angle.

In some embodiments, the user interface shown in fig. 7e is referred to as a camera setup interface, which includes at least an item for adjusting the initial angle of the camera.

In some embodiments, when the selector falls on a sub-setting item for adjusting the initial angle of the camera, a user interface containing specific prompt information for instructing a user how to adjust the initial angle of the camera is presented. Illustratively, in fig. 7e, when the selector falls on the item "manual adjustment", a specific prompt message as shown in fig. 7f is displayed in an area where the sub setting item is not occluded in the upper layer of the menu page. As shown in fig. 7f, the specific prompt message is a text prompt of "adjusting the camera angle by pressing the up, down, left and right buttons of the remote controller".

In some embodiments, the display device controller directly starts the camera and presents an image captured by the camera in response to receiving a user operation on a setting item in the interface for adjusting an initial angle of the camera. Illustratively, in fig. 7e, after the user operates the item "manual adjustment", in response to the received operation on the item "manual adjustment", the display device controller starts the camera and presents the image captured by the camera in the user interface. Specifically, a video display window is arranged in the user interface, and an image acquired by the camera is presented in the video display window. Illustratively, the user interface shown in FIG. 7e changes to the user interface shown in FIG. 7h in response to a received operation on the item "manually adjust".

In other embodiments, the display device controller presents a user interface including operation information for adjusting the initial angle of the camera in response to receiving a user operation on a setting item for adjusting the initial angle of the camera in the interface, and then, a user can know how to adjust the initial angle of the camera according to the displayed operation information. In addition, a control for starting the camera and presenting the image collected by the camera is further provided on the user interface containing the operation information for adjusting the initial angle of the camera, and the user can instruct to start the camera and present the image collected by the camera by operating the control. Illustratively, the display device controller, in response to an operation of "manually adjusting" the item as in fig. 7e, presents a user interface as shown in fig. 7g, which displays operation information for adjusting the initial angle of the camera and a control "i know". When the user operates the control "i know", the display device controller starts the camera and presents the image captured by the camera, that is, the user interface shown in fig. 7g enters the user interface shown in fig. 7 h.

In the embodiment of the present application, in the scene of initial angle adjustment of the camera, when the preview screen of the camera shown in fig. 7h is displayed, a user may adjust the angle of the camera by operating a designated key (e.g., a direction key) on the remote controller. Taking an entity direction key used for adjusting the angle of the camera on the remote controller as an example, when a user presses a certain direction key, the controller responds to the received user operation and controls the camera to perform incremental adjustment to the target adjustment direction on the basis of the current angle according to the target adjustment direction indicated by the key operated by the user. For example, if the target adjustment direction indicated by the key operated by the user is "right", and the angle at which the camera is located when the user operation is received is 15 °, 10 ° is adjusted to the right, that is, 25 °, on the basis of 15 °.

In some embodiments, the operation for adjusting the initial angle of the camera is referred to as an adjustment operation.

In addition, in the process of adjusting the initial angle of the camera, the display device controller periodically acquires the current angle of the camera and judges whether the current angle of the camera reaches the limit angle corresponding to the target adjustment direction; and when the current angle of the camera reaches the limit angle corresponding to the target adjustment direction, stopping adjusting the angle of the camera, and displaying a Toast prompt on the upper layer of the current playing picture.

In some embodiments, in the camera initial angle adjustment scenario, the user may input an instruction indicating to save the initial angle by operating a key on the control device for saving the initial angle, which may be a "confirm" key as shown in fig. 7 g. And the display equipment controller responds to the instruction for indicating the storage of the initial angle and stores the current angle of the camera as the initial angle. And then, when the camera is started subsequently, the camera is controlled to rotate to the initial angle according to the stored initial angle.

In some embodiments, the above-described key operation for saving the initial angle is referred to as a saving operation.

In some embodiments, in the camera initial angle adjustment scenario, the user may input an instruction indicating to reset the initial angle by operating a key for resetting the initial angle on the control device, which may be a "menu" key as shown in fig. 7 g. And the display equipment controller responds to the instruction for resetting the initial angle and saves the preset initial angle as the initial angle. For example, the preset initial angle may be a factory initial angle, such as 60 ° horizontally and 9 ° vertically.

In some embodiments, the above-described key operation for resetting the initial angle is referred to as a reset operation.

In some embodiments, in the initial angle adjustment scenario, operation information for adjusting the initial angle of the camera is presented on an upper layer of the displayed image captured by the camera. For example, operation information for adjusting the initial angle of the camera is displayed in the lower right corner area of the upper layer of the camera preview screen shown in fig. 7 h.

It should be understood that the initial camera angle adjustment scenario includes, but is not limited to, the interaction scenario shown in fig. 7f, and may also be a setting scenario provided by an application that needs to invoke the camera, which is not described herein again.

In some more specific implementations, the system setup application receives a user operation and invokes the camera control service, and performs processing corresponding to the user operation through the camera control service. Illustratively, when the system setting application receives an operation for adjusting the angle of the camera (such as a pressing operation on a direction key on a remote controller), a specific interface (such as rota aroundaxiso to ()) provided by the camera control service is called through the Hid1 cross-process communication according to a target adjustment direction corresponding to the user operation and a preset adjustment step length, so as to control the rotation of the pan-tilt camera. For another example, in the process of controlling the pan/tilt/zoom camera to rotate, the system setup application periodically obtains the current angle of the camera by calling a specific interface (e.g. getpivoting ()) provided by the camera control service, and when it is determined that the current angle of the camera reaches the corresponding limit angle, the camera control service is turned off to terminate the pan/tilt/zoom camera rotation.

Based on the above embodiments, in other embodiments, the display device controller starts the camera in response to an instruction instructing to start the camera, and adjusts the angle of the camera to the saved initial angle in a case where the angle of the camera is not the saved initial angle.
