Description

[0001] This application claims the priority of a Chinese patent application with the application number 202210113987.2 and the application title "Shooting Method, Device, Storage Medium and Program Product of a Multi-Camera Shooting System", which was filed with the Chinese Patent Office on January 30, 2022. The entire content thereof is incorporated herein by reference. Technical Field

[0002] Embodiments of this application relate to the technical field of video shooting, and particularly to a shooting method, device, storage medium and program product of a multi-camera shooting system. Background Art

[0003] A multi-camera shooting system refers to a system that uses multiple imaging devices to shoot an object to be photographed; it is a commonly used shooting technique in movies, live broadcast platforms, and stage shootings. Through this technique, the pictures of stories and live broadcasts can be made more vivid and have a better sense of substitution.

[0004] A mobile phone and a small handheld shooting device can be combined into a multi-camera shooting system through short-range communication technologies such as WiFi, bringing a more convenient shooting experience to users. For a multi-camera shooting system composed of a mobile phone or a small handheld shooting device, the shooter often needs to select or splice video images of multiple shooting positions during the shooting creation process. We usually refer to the video preview screens of multiple positions as the director's view, the mobile phone or wireless shooting device that controls the shooting of other positions in the multi-camera shooting system as the main position, and the mobile phone or wireless shooting device that is controlled as the auxiliary position.

[0005] In the existing related technologies, there are two ways of the director's view used in a multi-camera shooting system composed of a mobile phone and a small shooting device. One way is without a director's view. That is, when the main position records a video and selects to switch the lens, only a prompt box showing the names of the alternative lenses can be displayed. After the selection is successful, it directly switches to the corresponding lens image, without a director's view. Another way is the way of locking the shooting lens once the preview image is selected. That is, before shooting a video, the main position will present all the lens images that may be used. The shooter can select any 2 images from them to start shooting, but only the images of these two lenses can be recorded during the shooting process, and re-selection is not allowed, that is, the video image cannot be switched. Since the shooting process of the existing technology cannot present a director's view or cannot switch the shooting image, the flexibility of video shooting is poor. Summary of the Invention

[0081] To better understand the technical solutions of this specification, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0082] It should be clear that the described embodiments are only a part of the embodiments of this specification, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this specification without creative efforts belong to the scope protected by this specification.

[0083] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit this specification. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0084] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0085] It should be understood that in the various embodiments of the present application, “first”, “second”, etc. are only used to refer to different objects and do not mean any other limitations on the objects referred to.

[0086] See also Figure 1 , Figure 1 This is a structural schematic diagram of a multi-camera shooting system provided in an embodiment of the present application. The shooting method and device provided in the embodiment of the present application can be applicable to the multi-camera shooting system, and the multi-camera shooting system includes at least two wireless shooting devices. For example, the multi-camera shooting system 10 includes three wireless shooting devices: a first electronic device 100, a second electronic device 200 and a third electronic device 300. One wireless shooting device is a camera of the multi-camera shooting system. In order to select and switch the video images shot by each camera in the multi-camera shooting system, a convenient way is to integrate the director screen into the host position of the multi-camera shooting system. Therefore, the first electronic device 100 is used as the host position of the multi-camera shooting system. The first electronic device 100 as the host position needs to shoot video images and manage the video images shot by each camera in the multi-camera shooting system. Therefore, the first electronic device 100 needs to have at least shooting function, display function, communication function and data processing function. The first electronic device 100 can be a mobile phone or other wireless shooting device. The second electronic device 200 and the third electronic device 300 are auxiliary cameras of the multi-camera shooting system. The electronic devices as auxiliary cameras need to shoot video images and transmit them to the host position. Therefore, the second electronic device 200 needs to have at least shooting function and communication function. The second electronic device 200 and the third electronic device 300 can be wireless shooting devices or mobile phones without display function. Before shooting, the main camera and auxiliary camera in the multi-camera shooting system need to be networked first to establish a communication connection. After that, the main camera can send control instructions to the auxiliary camera through the communication connection. The auxiliary camera can realize, for example, picture control of the shot video, control of the shooting camera, control of whether the video image is transmitted to the main camera, control of whether the auxiliary camera is in sleep mode, etc. according to the control instructions.

[0087] Among them, the first electronic device 100, the second electronic device 200, and the third electronic device 300 are connected through a wireless communication network, for example, a wireless communication connection can be established through WiFi. The instruction transmission and data transmission between the first electronic device 100, the second electronic device 200, and the third electronic device 300 can be transmitted through a WiFi wireless communication link. In order to realize the management and control of the video images captured by the slave camera position by the master camera position, the master camera position can set the Camera Hardware Abstraction Layer (CameraHAL), and the slave camera position can set the Virtual Camera Agent (VirtualCameraAgent). When the master camera position detects that the control instruction involves the remote slave camera position, the control instruction is forwarded to the Virtual Camera Agent of the peer slave camera position through the CameraHAL to control the slave camera position. The Virtual Camera Agent of the slave device is used to escape the control instruction sent by the peer master camera position to the corresponding ISP and then control the camera. For example, it can be realized that the master camera position allows the peer slave camera position to transmit the video image to the master camera position, and the video image of the slave camera position is presented on the master camera position.

[0088] It can be understood that the structure of the multi-camera shooting system 10 illustrated in the embodiments of the present application does not limit the structure of the multi-camera shooting system 10. In other embodiments of the present application, the multi-camera shooting system 10 may include more or fewer wireless shooting devices than those shown in the figure. Generally, one master camera position is set in the multi-camera shooting system 10, and in special cases, multiple master camera positions may also be set.

[0089] See Figure 2 , Figure 2 which is a schematic diagram of the camera of an electronic device provided by the embodiments of the present application. In Figure 2 , a mobile phone is taken as an example to Figure 1 exemplarily illustrate the first electronic device 100 in Figure 2 . The front view and rear view of the mobile phone are shown. Two front cameras 111 and 112 are arranged on the front side of the mobile phone, and four rear cameras 121, 122, 123, and 124 are arranged on the rear side of the mobile phone. By configuring multiple cameras, multiple shooting modes can be provided for users, improving the flexibility of users' video shooting.

[0090] It can be understood that Figure 2The illustration is only exemplary and should not be regarded as a limitation on the protection scope of this application. For example, different mobile phones may have different numbers and positions of camera configurations. In addition, the electronic devices involved in the embodiments of this application may include, in addition to mobile phones, tablet computers, personal computers (PCs), personal digital assistants (PDAs), smart watches, netbooks, wearable electronic devices, augmented reality (AR) devices, virtual reality (VR) devices, in-vehicle devices, smart cars, smart speakers, robots, smart glasses, smart TVs, etc. In some possible implementation manners, the electronic device may also be referred to as a terminal device, a user equipment (UE), etc., and the embodiments of this application do not limit this. In addition, Figure 1 the second electronic device and the third electronic device shown may also adopt Figure 2 the electronic device shown.

[0091] In an actual application scenario, after the multi-camera shooting system network is successfully established, the electronic devices at multiple camera positions all enter the working mode. When the electronic device acting as the main camera position enters the video shooting mode, the main interface will be displayed on the main camera position. The main interface is used to display video images. The video images displayed here are the video images provided by the main camera position or the secondary camera positions. When the main camera position is successfully networked for the first time, one video image provided by the main camera position or the secondary camera positions in the multi-camera shooting system can be displayed as the initial video image in the main interface according to the pre-setting of the system.

[0092] Refer to Figure 3 , Figure 3 which is a schematic flowchart of a shooting method for a multi-camera shooting system provided by an embodiment of this application, and is applied to Figure 1 the first electronic device 100 of the multi-camera shooting system shown. The first electronic device 100 is the main camera position of the multi-camera shooting system. As Figure 3 shown, the shooting method may include:

[0093] Step 1000: As Figure 4a shown, the first electronic device displays the main interface 20. The main interface 20 is the interface for the host or the recorder to view. The main interface 20 includes the first video image 201. The first video image 201 is, for example, an image of a person holding a bicycle;

[0094] Step 1001: The first electronic device receives a first user operation in the video shooting mode;

[0095] Step 1002: As Figure 4bAs shown, according to the first user operation, the first electronic device displays the second video image 202 on the main interface 20. The second video image 202 is, for example, a meditation screen. The first video image 201 and the second video image 202 can be overlapped and displayed on the main interface 20. The display area of the first video image 201 can be larger than that of the second video image 202. The second video image 202 can be displayed on the upper layer of the first video image 201. The first video image 201 comes from the main camera position or the secondary camera position, and the second video image 202 comes from the secondary camera position. That is, the first video image 201 and the second video image 202 are video images provided by different camera positions in a multi-camera shooting system;

[0096] At this time, the first video image 201 is a recording screen or a live broadcast screen, that is, the first video image 201 will be recorded and saved or transmitted to the server for live broadcast, which is the video image finally presented to the audience. The second video image 202 is a non-recording screen, or a director's screen, that is, the second video image 202 is only used for the host to preview and will not be presented to the audience for viewing. If the second video image 202 comes from the second electronic device, then when the first electronic device displays the second video image 202 on the main interface 20, the first electronic device will send an instruction to the second electronic device to obtain the second video image, and the second electronic device will transmit the second video image it shoots to the first electronic device according to this instruction.

[0097] Step 1003: The first electronic device receives a video switching operation, and the video switching operation is directed at the second video image 202. For example, the user clicks on the meditation screen in the main interface 20;

[0098] Step 1004: As Figure 4c shown, according to the video switching operation, the first electronic device switches the first video image 201 and the second video image 202, that is, switches the first video image 201 to the original display area of the second video image 202, and switches the second video image 202 to the original display area of the first video image 201. After the switching, the first video image 201 becomes a director's screen only used for the host to preview and will no longer be presented to the audience for viewing. The second video image 202 becomes a recording screen or a live broadcast screen and is presented to the audience for viewing. At this time, the first video image 201 can be displayed on the upper layer of the second video image 202.

[0099] For example, when the user clicks on the meditation screen in the Figure 4b shown main interface 20, the first electronic device will perform video image switching, and the main interface 20 will be switched from as Figure 4b shown to as Figure 4c shown. In addition to the switching of the video images in the interface, in terms of function, this video switching operation switches the meditation screen to a recording screen and switches the hand-held bicycle screen to a director's screen.

[0100] Specifically, when the first electronic device (host device) successfully networks with the secondary device, the first electronic device 100 enters the shooting application. Here, the shooting application includes, but is not limited to, shooting or live broadcast applications, which can be the camera application on a mobile phone or other applications that support a multi-camera system. When the first electronic device 100 enters the shooting application and is in the video shooting mode, the user can see the first video image 201 on the main interface 20. If the user wishes to view the video images provided by each camera through the director's screen, the user can perform a first user operation to cause the second video image 202, which serves as the director's screen, to be displayed on the main interface 20, so that while viewing the video image from one camera on the main interface 20, the user can also view the video image from another camera.

[0101] When the user wishes to switch the second video image 202 to a recording screen, a video switching operation is performed. It should be noted that the main interface 20 can include multiple second video images 202. For example, the user can see multiple second video images 202 provided by multiple cameras through the main interface 20. The user can select a certain second video image to be recorded from the main interface 20 and switch it with the first video image 201 to achieve the recording of this second video image 202, that is, select the second video image 202 to be recorded from the main interface 20 through the video switching operation and switch it with the first video image 201. By switching the video images, the flexibility of video shooting is improved. Additionally, the original first video image 201 on the main interface 20 is switched to the director's screen, so that the host can continue to view the first video image 201 on the main interface 20.

[0102] Exemplarily, the main interface 20 includes operation controls, such as a video recording button, a pause button, a floating ball, a zoom button, etc. The floating ball can be dragged to any position. The floating ball is used to trigger the display of the second video image on the main interface. For example, the first user operation includes a click operation on an operation control (such as the floating ball), or the first user operation includes a first swipe gesture operation on a preset position 30. For example, as Figure 4b shown, the preset position 30 is the display area corresponding to the second video image 202 before video switching; before the video switching operation, the video switching operation includes a single click operation on the second video image 202. This single click operation can be a quick single click operation or a long press operation. For example, the first swipe gesture operation is a right swipe gesture operation. When the user performs a right swipe gesture operation at the preset position 30 on the lower left side of the main interface 20 as Figure 4a shown, the main interface 20 will change to as Figure 4b shown, and the second video image 202 will be displayed. Again, for example, when the first electronic device displays a floating ball, when the user clicks as Figure 4aAfter the floating ball shown, the main interface 20 will become as Figure 4b shown, and display the second video image 202. The first user operation can also be other forms of user operations, such as virtual button operations, physical button operations, etc. This embodiment does not limit the form of the first user operation.

[0103] Exemplarily, the video switching operation can include a long - press operation by the user on the second video image 202. For example, when the user long - presses the second video image 202 as Figure 4b shown, the main interface 20 will become as Figure 4c shown, and the first video image 201 and the second video image 202 are switched. At this time, if the user long - presses the first video image 201, then the first video image 201 and the second video image 202 will be switched again, that is, the main interface 20 will change back to as Figure 4b shown. The video switching operation can also be other forms of user operations, such as virtual button operations, physical button operations, etc. For example, the main interface 20 can include a video switching control, and the video switching operation can include an operation on the video switching control. This embodiment does not limit the form of the video switching operation.

[0104] Further, when the user does not need to use the non - recorded screen, the second video image 202 as Figure 4b shown can be hidden, or the first video image 201 as Figure 4c shown can be hidden, so that the user can better view the video image of the ongoing recording.

[0105] As Figure 4a - 4d and Figure 5a shown, on the basis of the embodiment as Figure 3 shown, after the process in which the first electronic device in step 1004 switches the first video image 201 and the second video image 202 according to the video switching operation, the shooting method can further include:

[0106] Step 1005: The first electronic device receives a second user operation;

[0107] Step 1006: The first electronic device hides the first video image 201 on the main interface according to the second user operation, that is, according to the second user operation, the screen display state of the first electronic device changes from Figure 4c to Figure 4d , and in this example, after hiding the first video image 201, the main interface 20 only displays the second video image 202.

[0108] When the user needs to display the first video image 201 again, steps 1007 and 1008 can also be executed. Step 1007: Receive the third user operation. Step 1008: According to the third user operation, display the first video image 201 on the main interface 20. The way of displaying or hiding the non-recording screen as needed improves the flexibility of video shooting. Among them, if the first video image 201 comes from the second electronic device, when the first electronic device hides the first video image 201 on the main interface, there may be two situations for the second electronic device. One situation is that the second electronic device still transmits the first video image to the first electronic device so that the first electronic device can quickly resume displaying the first video image. The other situation is that the second electronic device receives an instruction from the first electronic device and no longer transmits the first video image to the first electronic device according to this instruction to save power. However, if the first electronic device needs to resume displaying the first video image, the first electronic device needs to send an instruction to resume displaying the first video image to the second electronic device. The second electronic device receives this instruction and resumes transmitting the first video image to the first electronic device according to this instruction. If the second electronic device is a mobile phone, during the process of the first electronic device hiding the first video image, the screen of the second electronic device can always display the first video image or can also hide the first video image at the same time.

[0109] Figure 5b The process shown is another shooting process parallel to Figure 5a the process shown. On the basis of the embodiment shown in Figure 3 after the first electronic device displays the second video image and before the first electronic device receives the video switching operation, that is, after step 1002 and before step 1003, the shooting method further includes: receiving the second user operation; according to the second user operation, hiding the second video image on the main interface, even if the interface shown in Figure 4b becomes the interface shown in Figure 4a receiving the third user operation; according to the third user operation, displaying the second video image on the main interface, even if the interface shown in Figure 4a is restored to the interface shown in Figure 4b After that, steps 1003 and 1004 can be executed to implement video switching, so that the interface shown in Figure 4b becomes the interface shown in Figure 4c shown.

[0110] That is to say, in the process shown in Figure 5a after the user executes the video switching operation, the first video image 201 as the non-recording screen is hidden; in Figure 5bIn the process shown, the user can first hide the second video image 202 that is not the recorded screen, and can watch the first video image 201 in a larger screen through the main interface 20. When a video switch is needed, first restore the display of the second video image 202 by performing a third user operation, and then perform a video switch operation.

[0111] In addition, it should be noted that in 5a and Figure 5b In the process shown, the third user operation can be the same as the above-mentioned first user operation, or different from the above-mentioned second user operation.

[0112] Exemplarily, the operation control (such as a floating ball) is used to trigger hiding the first video image on the main interface and hiding the first video image on the main interface. For example, the second user operation and the third user operation include click operations on the operation control (such as a floating ball). In addition, the third user operation can also include a first swipe gesture operation on a preset position 30; the second user operation can include a second swipe gesture operation on the preset position 30. The first swipe gesture operation and the second swipe gesture operation can be swipe gesture operations in opposite directions. For example, the second swipe gesture operation is a left swipe gesture operation. For example, when the user performs a left swipe gesture operation at the preset position 30 as Figure 4c shown, or clicks the floating ball, the first video image 201 will be hidden, and the main interface 20 will become as Figure 4d shown. After that, if the user performs a right swipe gesture operation at the preset position 30 as Figure 4d shown, or clicks the floating ball, the main interface 20 will become as Figure 4c shown, that is, the display of the first video image 201 is restored. In addition, the second user operation and the third user operation can also be other forms of user operations, such as virtual key operations, physical key operations, etc. The forms of the second user operation and the third user operation are not limited in this embodiment.

[0113] The following further describes the above embodiments based on Figure 4a - 4d this.

[0114] See Figure 4a , a first video image 201 is displayed on the main interface 20 of the first electronic device. The first video image 201 is a video image provided by the first electronic device or the secondary camera position.

[0115] Among them, the first video image 201 can be recorded. When the user performs a video recording operation, for example, when the user clicks the video recording button, the first electronic device receives the video recording operation, saves the data of the first video image 201, or transmits the data of the first video image 201 to the server for live streaming, etc. The data of the video image is obtained by the camera providing the video image and transmitted to the first electronic device, and then saved by the first electronic device after encoding processing.

[0116] It can be understood that in order to display the first video image 201 more clearly, the first video image 201 can be full-screen displayed on the main interface 20, or it can be not full-screen displayed, but medium-screen displayed or small-screen displayed. Specifically, it can be set according to the user's needs. This embodiment does not limit the size of the first video image 201.

[0117] In addition, the first video image 201 is a video image provided by the first electronic device or the auxiliary camera. If the display screen of the first electronic device is small, the main interface 20 can only display one first video image. If the display screen of the first electronic device is large, the main interface 20 can also display multiple first video images. The multiple first video images can come from different cameras or different cameras of the same camera. For example, when the main interface 20 displays two first video images, the two first video images can be vertically tiled or horizontally tiled and displayed on the main interface. In the actual application scenario, it can be set based on the screen size of the first electronic device. This embodiment does not limit the number of first video images displayed on the main interface.

[0118] See Figure 4b . After receiving the first user operation, the second video image 202 is displayed on the main interface 20. The second video image 202 is a video image provided by the first electronic device or the auxiliary camera. The first video image 201 and the second video image 202 are video images provided by different cameras.

[0119] It can be understood that, in order not to affect the user's viewing of the first video image 201, the display size of the second video image 202 will not be set too large. Generally, the display size of the second video image 202 is smaller than that of the first video image 201, and the resolution of the second video image 202 is lower than that of the first video image 201. When the video image of the secondary camera position is the second video image 202, the first electronic device sends a video acquisition instruction to the secondary camera position, and the secondary camera position can transmit the low-resolution video image to the first electronic device to reduce the amount of data transmission. If the first video image 201 is full-screen displayed, the second video image 202 will be superimposed on the first video image 201 for display. If the first video image 201 is not full-screen displayed, the second video image 202 can be superimposed or not superimposed on the first video image 201 for display. In this embodiment, the size, position of the second video image, and the positional relationship with the first video image are not limited.

[0120] In addition, when the display screen of the first electronic device is relatively large, the main interface 20 may include more than one second video image. For example, the main interface 20 may display two second video images, and the two second video images may be tiled vertically or horizontally in a partial area of the main interface 20. In the actual application scenario, it can be set based on the size of the display screen and the size of the main interface. In this embodiment, the number of the second video images 202 is not limited.

[0121] See Figure 4c . In Figure 4b the shown scenario, after the first electronic device receives the user's video switching operation, the video switching operation is directed to the second video image 202. As Figure 4c shown, the display effects of the first video image 201 and the second video image 202 in the main interface 20 are switched. At the same time, in the background, the first video image 201 is switched to a non-recording screen, and the second video image 202 is switched to a recording screen.

[0122] In a possible implementation manner, one of the first video image and the second video image comes from the second electronic device 200, and the second electronic device 200 is a secondary camera position of a multi-camera shooting system; the other of the first video image and the second video image comes from the first electronic device 100 or the third electronic device 300, and the third electronic device 300 is another secondary camera position of the multi-camera shooting system. That is to say, in Figure 4b or Figure 4c the shown scenario, combined with Figure 1In the multi-camera shooting system shown, in a possible shooting process, one of the first video image 201 and the second video image 202 is taken by the first electronic device 100 itself, and the other of the first video image 201 and the second video image 202 is taken by the second electronic device 200; in another possible shooting process, one of the first video image 201 and the second video image 202 is taken by the second electronic device 200, and the other of the first video image 201 and the second video image 202 is taken by the third electronic device 300.

[0123] See Figure 4d , Figure 4d is Figure 4c a schematic diagram of the scene after the first electronic device in hides the first video image. After receiving the second user operation, as Figure 4d shown, the main interface 20 hides the first video image, and at this time the main interface 20 only displays the second video image 202.

[0124] In some embodiments, when the user needs to view other video images, it can be achieved by performing a camera position switching operation.

[0125] Such as Figure 6 shown, on the basis of the embodiment shown in Figure 3 after the first electronic device switches the first video image 201 and the second video image 202 according to the video switching operation, the shooting method may further include:

[0126] Execute step 1009: The first electronic device receives a camera position switching operation, and the camera position switching operation is directed at the first video image 201;

[0127] Execute step 1010: The first electronic device replaces the first video image 201 with a third video image 203 according to the camera position switching operation, and the first video image 201 and the third video image 203 are video images provided by different camera positions in the multi-camera shooting system.

[0128] For example, a multi-camera shooting system includes three electronic devices. Before receiving the camera position switching operation, the second video image 202 on the main interface 20 of the first electronic device 100 is a video image captured by the camera of the first electronic device 100 itself. For example, it is a meditation scene. The second video image 202 on the main interface 20 of the first electronic device 100 is a video image captured by the second electronic device 200. For example, it is a scene of a person holding a bicycle. The video image captured by the third electronic device 300 (for example, a landscape scene) is not yet displayed on the first electronic device 100. After receiving the camera position switching operation, according to the camera position switching operation, the scene of a person holding a bicycle on the main interface 20 of the first electronic device 100 is switched to a landscape scene. That is, it realizes the switching of the non-recording scene on the main interface 20 to the video images provided by different camera positions.

[0129] When the user needs to switch the non-recording scene based on the camera position, the user can perform the camera position switching operation so that the user can view the video images provided by other camera positions through the main interface 20 of the first electronic device 100. When the first electronic device 100 receives the camera position switching operation, the video image of another camera position provided by the main camera position or the auxiliary camera position is displayed at the position of the non-recording scene. For example, there are four camera positions providing video images for the main camera position and the auxiliary camera position. Among them, the video image provided by one camera position is the recording scene on the main interface 20, and the video images provided by the remaining three camera positions can all be presented as the non-recording scenes on the main interface 20. If only the video image provided by one camera position is currently displayed as the non-recording scene and the video images provided by the other two camera positions are not displayed on the main interface 20, then by performing the camera position switching operation once, the non-recording scene on the main interface 20 is switched to the video image provided by another camera position. By repeatedly performing the camera position switching operation, the user can view the video images provided by the three camera positions in turn. Through the camera position switching operation, the user can easily view the video images of all camera positions that have not entered the main interface 20, which is convenient for the user to view the video images of different camera positions.

[0130] Exemplarily, the camera position switching operation includes a double-click operation on the first video image 201. For example, when the user double-clicks on the first video image 201 displayed on the main interface 20, the first video image 201 is switched to the third video image 203 of another camera position. If the user continues to double-click on the third video image 203, the third video image 203 is switched to the video image of another camera position, and so on. Each double-click switches once. The order of camera position switching can be preset by the system. The camera position switching operation can also be other forms of operations, such as virtual key operations, physical key operations, etc. For example, the main interface can include a camera position switching control, and the camera position switching operation can include an operation on the camera position switching control. The form of the camera position switching operation is not limited in this embodiment.

[0131] During the camera position switching process, different situations may exist for the second electronic device and the third electronic device. During the camera position switching process of the first electronic device, the second electronic device can continuously transmit the first video image to the first electronic device, and the third electronic device can also transmit the third video image to the first electronic device, so that the first electronic device can quickly resume displaying the first video image or the third video image. Additionally, when switching the camera position, the first electronic device can also send instructions to the second electronic device and the third electronic device. For example, the second electronic device receives an instruction from the first electronic device and stops transmitting the first video image to the first electronic device according to this instruction to save power consumption. The third electronic device receives an instruction from the first electronic device and resumes transmitting the third video image to the first electronic device according to this instruction. If the second electronic device and the third electronic device are mobile phones, during the camera position switching process of the first electronic device, the screen of the second electronic device can always display the first video image, or the second electronic device can hide the first video image after the first electronic device switches the first video image to the third video image. The screen of the third electronic device can always display the third video image, or the third electronic device can start displaying the third video image after the first electronic device switches the first video image to the third video image.

[0132] In some embodiments, such as Figure 7 shown, for example, when the second electronic device 200 is Figure 2 a mobile phone including a front camera and a rear camera as shown, when the first video image in the main interface 20 of the current first electronic device 100 comes from the rear camera of the second electronic device 200, in order to view the video image provided by the front camera of the second electronic device 200, it can be achieved through a camera switching operation.

[0133] In Figure 3 the embodiment shown, after the first electronic device 100 switches the first video image 201 and the second video image 202 according to the video switching operation, the shooting method may further include:

[0134] Performing step 1011: The first electronic device 100 receives a camera switching operation, and the camera switching operation is directed at the first video image 201;

[0135] Performing step 1012: The first electronic device 100 replaces the first video image 201 with a fourth video image 204 according to the camera switching operation, and the first video image 201 and the fourth video image 204 are video images provided by different cameras of the same camera position in the multi-camera shooting system.

[0136] For example, the multi-camera shooting system includes a first electronic device 100 and a second electronic device 200. Among them, the second electronic device 200 has a front camera and a rear camera. Before receiving the camera switching operation, the second video image 202 in the main interface 20 of the first electronic device 100 is a video image captured by the camera of the first electronic device 100 itself. For example, it is a meditation picture. The first video image 201 in the main interface 20 of the first electronic device 100 is a video image captured by the rear camera of the second electronic device 200. For example, it is a picture of a person holding a bicycle. At this time, the second electronic device 200 also displays the picture of a person holding a bicycle captured by its rear camera. After receiving the camera switching operation, according to the camera switching operation, the first electronic device 100 switches the first video image 201 in the main interface 20 to the fourth video image 204. The fourth video image 204 is a self-portrait picture captured by the front camera of the second electronic device 200. According to the camera switching operation, a corresponding control instruction can also be sent to the second electronic device 200 to make the second electronic device 200 also switch to display the self-portrait picture captured by its front camera. That is, it realizes the switching of the non-recording picture in the main interface 20 of the first electronic device 100 to the video images provided by different cameras of the same camera position.

[0137] When the user needs to switch the non-recording picture in the main interface 20 of the first electronic device 100 to the video image provided by another camera of the same camera position, the camera switching operation can be performed. When the first electronic device 100 receives the camera switching operation, it will switch the current non-recording picture in the main interface 20 to the video image provided by another camera of the same camera position. Through the camera switching operation, the user can easily view the video images provided by each camera of the same camera position, which is convenient for the user to watch the video images of different cameras and improves the flexibility of video shooting.

[0138] Exemplarily, the camera switching operation includes a triple-click operation on the first video image 201. For example, when the user triple-clicks on the first video image 201 in the main interface 20, the first video image 201 will be switched to the video image provided by another camera of the same camera position. If there are more than two cameras, the triple-click operation can continue. Each triple-click will cause a switch. The order of camera switching can be preset by the system. The camera switching operation can also be other forms of operations, such as virtual key operations, physical key operations, etc. For example, the main interface 20 can include a camera position switching control. The camera position switching operation can include an operation on the camera position switching control. The form of the camera switching operation in this embodiment is not limited.

[0139] During the camera switching process, different situations may occur for the second electronic device. During the camera switching process of the first electronic device, the second electronic device can continuously transmit the first video image and the fourth video image to the first electronic device, so that the first electronic device can quickly resume displaying the first video image or the fourth video image. Additionally, when the camera is switched, the first electronic device can also send an instruction to the second electronic device. For example, before the first electronic device receives the camera switching operation, both the first electronic device and the second electronic device display the first video image. When the first electronic device receives the camera switching operation, it sends a corresponding instruction to the second electronic device, and the second electronic device displays the fourth video image according to this instruction, and the first electronic device switches the first video image to the fourth video image. Additionally, before the camera is switched, the second electronic device may not have transmitted the fourth video image to the first electronic device. In this case, when the second electronic device receives the instruction from the first electronic device, it can transmit the fourth video image to the first electronic device to facilitate the camera switching of the first electronic device.

[0140] In some embodiments, in order to meet the diverse requirements of users for shooting videos and increase the presentation methods of videos, a picture-in-picture effect can also be added to the recorded screen.

[0141] Such as Figure 8 shown, based on the embodiment shown in Figure 3 after the process of the first electronic device 100 switching the first video image 201 and the second video image 202 according to the video switching operation, the shooting method may further include:

[0142] Performing step 1013: The first electronic device 100 receives a picture-in-picture display operation, and the picture-in-picture display operation is directed at the first video image 201;

[0143] Performing step 1014: The first electronic device 100, according to the picture-in-picture display operation, displays at least a part of the fifth video image 205 surrounded by the second video image 202 on the main interface 20. The fifth video image 205 is the same as the first video image 201, and the fifth video image 205 and the second video image 202 are the recorded screen or the live broadcast screen, that is, the superimposed screen of the fifth video image 205 and the second video image 202 is used to present to the audience for viewing.

[0144] For example, the picture-in-picture display operation includes a drag operation on the first video image 201. When the user holds the first video image 201 and drags it upward, the fifth video image 205 will be generated.

[0145] It can be understood that the display size of the fifth video image 205 is smaller than that of the second video image 202, and the resolution of the fifth video image 205 is lower than that of the second video image 202. When the fifth video image 205 comes from a certain secondary camera position, the secondary camera position can transmit a low-resolution video image to the first electronic device to reduce the amount of data transmission.

[0146] When the user needs to display a picture-in-picture effect in the recording screen, a picture-in-picture display operation can be executed to enable the main interface 20 of the first electronic device 100 to display the fifth video image 205 as a part of the recording screen. At least a part of the fifth video image 205 is surrounded by the second video image 202. The superposition of the fifth video image 205 and the second video image 202 is the recording screen, that is, the fifth video image 205 and the second video image 202 are recorded as superimposed video images, so as to be saved as a video screen with a picture-in-picture effect, or transmitted to the server for live broadcast to form a live broadcast screen with a picture-in-picture effect. The recording effect of the picture-in-picture video image increases the expression form of the video and improves the flexibility of video shooting.

[0147] Exemplarily, the picture-in-picture display operation can include a drag operation on the first video image 201. For example, when the user holds the first video image 201 displayed on the main interface 20 and drags it upward or in the upper right direction, the same fifth video image 205 as the first video image 201 will be additionally displayed on the main interface 20. The picture-in-picture display operation can also be other forms of operations, such as virtual key operations, physical key operations, etc. For example, if the main interface includes a picture-in-picture control, the picture-in-picture display operation can include an operation on the picture-in-picture control. The form of the picture-in-picture display operation in this embodiment is not limited. In addition, for the fifth video image 205, it can be dragged in any area covered by the main interface 20.

[0148] Exemplarily, by dragging the fifth video image 205 to move in the main interface 20, the user can move the position of the fifth video image 205 in the main interface 20, and the user can select the position to place the fifth video image 205 according to needs, improving the flexibility of video shooting.

[0149] Further, when the user does not need to display the fifth video image 205, the fifth video image 205 can be hidden to end the picture-in-picture display effect.

[0150] As Figure 9 shown, on the basis of the embodiment shown in Figure 8 when the main interface 20 of the first electronic device 100 displays the fifth video image 205, the shooting method can further include:

[0151] Step 1015 is executed: The first electronic device 100 receives a picture-in-picture hiding operation, which may include a dragging operation on the fifth video image 205. For example, when the user holds the fifth video image 205 and drags it upward and slides out of the boundary of the main interface 20, the fifth video image 205 will be hidden, that is, the fifth video image is not displayed on the main interface 20 of the first electronic device 100.

[0152] Step 1016: The first electronic device 100 hides the fifth video image 205 on the main interface 20 according to the picture-in-picture hiding operation.

[0153] It should be noted that when the user no longer needs the picture-in-picture effect, a picture-in-picture hiding operation can be performed to hide the fifth video image 205. When the user needs the picture-in-picture display again, a picture-in-picture display operation can be performed again to display the fifth video image 205. The way of displaying or hiding the picture-in-picture effect as needed improves the flexibility of video shooting.

[0154] Exemplarily, in addition to the dragging operation, the picture-in-picture hiding operation can also be other forms of operations, such as virtual key operations, physical key operations, etc. For example, the main interface includes a picture-in-picture control, and the third interface hiding operation can be an operation on the picture-in-picture control. The form of the third interface hiding operation is not limited in this embodiment.

[0155] It can be understood that Figure 8 and Figure 9 the superposition of the first video image 201 and the fifth video image 205 in

[0156] is a recording interface. When the user performs a video recording operation, such as clicking the video recording button, the first electronic device 100 receives the video recording operation and saves the video image data. The video image data is the video image data corresponding to the video image after the superposition of the first video image 201 and the fifth video image 205. The video image data is collected by the camera providing the video image and transmitted to the first electronic device 100, and the first electronic device 100 saves or transmits it to the server for live broadcast after encoding processing.

[0157] In addition, during the video image shooting process, there are usually some special effect controls, such as beauty effects, etc. These effects can be directly implemented on the video image on the first electronic device, or the special effect control instructions can be transmitted to the auxiliary camera corresponding to the video image. The corresponding auxiliary camera adjusts the video image according to the special effect control instructions and transmits the adjusted video image to the first electronic device 100 for display. Additionally, if the first electronic device 100 displays a fifth video image, that is, the picture-in-picture recording method is used, the same special effect control can be implemented on the second video image and the fifth video image, or different special effect controls can be implemented on the second video image and the fifth video image respectively.

[0158] In some embodiments, when the user operates on the video image displayed on the main interface 20 of the first electronic device 100, and the video image being operated on is provided by the auxiliary camera, the first electronic device 100 needs to send a shooting control instruction to the auxiliary camera so that the auxiliary camera transmits the operated video image to the first electronic device 100 for display. To reduce the delay of image display, the shooting control instructions sent by the first electronic device 100 to the auxiliary camera all need to be transmitted with priority.

[0159] In some embodiments, as Figure 1 and Figure 3 shown, assume that in step 1002 above, the second video image comes from the second electronic device 200, and the second electronic device 200 is an auxiliary camera of the multi-camera shooting system. The above step 1002: The process of the first electronic device 100 displaying the second video image 202 on the main interface 20 according to the first user operation includes:

[0160] Step 10021: The first electronic device 100 generates a data transmission control instruction according to the first user operation, and the data transmission control instruction carries a high-priority tag;

[0161] Step 10022: The first electronic device 100 transmits the data transmission instruction to the second electronic device 200 based on high priority;

[0162] Among them, the data transmission instruction is used to control the second electronic device 200 to transmit the second video image it shoots back to the first electronic device 100;

[0163] Step 10023: The first electronic device 100 receives the second video image sent by the second electronic device 200;

[0164] Step 10024: The first electronic device 100 displays the second video image 202 on the main interface 20.

[0165] In addition, the above method may further include: sending a focusing control instruction or a zoom control instruction, etc. to the second electronic device 200 based on a high priority according to a user operation. When the first electronic device 100 communicates with the second electronic device 200 via WiFi, shooting control instructions such as a data transmission control instruction, a focusing control instruction, and a zoom control instruction are transmitted via WiFi to the secondary camera position for shooting control. Figure 10 FIG. shows a schematic diagram of a transmission queue. Media Access Control Service Data Units (MSDUs) are mapped and classified into multiple transmission queues VO, A_VO, A_VI, VI, BE, and BK through the transmission queue and access category. VO refers to Voice, VI refers to Video, BE refers to Best effort, and BK refers to Background; the transmission queues will be classified into Enhanced Distributed Channel Access (EDCA) queues, and the EDCA queues include VO, VI, BE, and BK in order of decreasing priority. To provide a better user operation experience, in the embodiments of the present application, data packets of these shooting control instructions carry high-priority tags, and these data packets carrying high-priority tags are treated differently and placed in the EDCA queue of WiFi to be transmitted to the second electronic device using a high-priority queue (i.e., Figure 10 the VO queue in). Other control instructions other than the shooting control instructions and the transmission data of the video image are placed in the queue according to the protocol default. By transmitting the shooting control instructions to the second electronic device based on high priority, the problem of communication delay between the first electronic device and the secondary camera position is reduced.

[0166] In some embodiments, to reduce the power consumption of each camera position in a multi-camera shooting system, when the video image of a certain camera position is not displayed on the main interface of the first electronic device, the corresponding camera position can be controlled to enter a low-power working state.

[0167] Figure 11 FIG. is a schematic flowchart of a shooting method for another multi-camera shooting system provided by the embodiments of the present application. Based on the embodiment shown in Figure 1 before receiving a third user operation, for example, after step 1004, the first video image 201 comes from the second electronic device 200, and the second electronic device 200 is a secondary camera position of the multi-camera shooting system; the shooting method may further include:

[0168] Step 1005: Receive a second user operation;

[0169] Step 1006: Hide the first video image 201 on the main interface 20 according to the second user operation. For the specific processes of steps 1005 and 1006, please refer to the relevant description above. Figure 5a and Figure 5b related description content;

[0170] Step 1017: After hiding the first video image 201 on the main interface 20 and when the first electronic device 100 does not display the video image from the second electronic device 200, the first electronic device 100 sends a standby control instruction to the second electronic device 200. The standby control instruction is used to instruct the second electronic device 200 to turn off or operate any one or any combination of the following components in a low-power mode: camera module, image signal processor ISP, video processor VPU, display screen, and wireless communication link. The wireless communication link is used to transmit the video image from the second electronic device 200 to the first electronic device 100. For the second electronic device 200, if it receives the standby control instruction, it will enter standby according to the standby control instruction. For example, it will turn off or switch any of the above components or combinations to operate in a low-power mode.

[0171] Among them, the camera positions in the multi-camera shooting system may be mobile devices or other wireless shooting devices, which can only rely on their own power. For example, the second electronic device 200 can be a mobile phone. It is necessary to consider reducing the shooting power consumption of the mobile phone. The way to reduce power consumption is to turn off at least some components of the second electronic device 200 or control them to operate in a low-power mode when the second electronic device 200 is not in use to maintain the low power consumption of the device. For example, control the second electronic device 200 to enter the standby mode. That is to say, for the multi-camera shooting system, if the video image of a certain camera position is not displayed by the first electronic device 100, that is, not used by the first electronic device 100, then the first electronic device 100 can control the corresponding camera position to reduce power consumption by sending a standby control instruction to it. In addition, for the first electronic device 100 itself, if the video images it displays all come from the auxiliary camera positions, that is, the first electronic device 100 does not display the video images it shoots itself, then it can also control the components that do not affect the display, such as the camera module and image signal processor ISP of the first electronic device 100, to turn off or control them to operate in a low-power mode. For example, the multi-camera shooting system includes the first electronic device 100 and the second electronic device 200. As Figure 4c and Figure 4d shown, the second video image 202 comes from the video image shot by the first electronic device 100 itself, and the first video image 201 comes from the second electronic device 200. After the first electronic device 100 hides the first video image 201 on the main interface 20, the first electronic device 100 may send a corresponding standby control instruction to the second electronic device 200 to control the second electronic device 200 to enter the standby mode to save power.

[0172] In addition, in a possible implementation, after the user hides the first video image 201, it is possible that the user will re-control the display of the first video image 201 in a very short time. To improve the situation where it is necessary to frequently control the second electronic device 200 to standby and resume from the standby mode in this case, the above step 1017: after hiding the first video image 201 on the main interface 20 and the first electronic device 100 does not display the video image from the second electronic device 200, the process of the first electronic device 100 sending a standby control instruction to the second electronic device 200 may include:

[0173] When the first electronic device 100 hides the first video image 201 on the main interface 20 for a preset time or more and the first electronic device 100 does not display the video image from the second electronic device 200 within the preset time, the first electronic device 100 sends a standby control instruction to the second electronic device 200, so as to prevent the second electronic device 200 and the wireless communication link from being frequently awakened from the standby mode.

[0174] The first electronic device 100 may be provided with a detection module for periodically detecting a target camera position whose video image is not used in the display screen of the local device. When the target camera position is detected, the target camera position is notified to enter the standby mode and the corresponding device is turned off.

[0175] When at least some components of the second electronic device 200 are turned off or controlled to work in the low power consumption mode, if the first electronic device 100 uses the video image of the second electronic device 200 again, the secondary camera position needs to be quickly awakened. It should be noted that the quick start of the second electronic device 200 entering the standby mode requires: 1) quickly restoring the wireless communication link; 2) quickly restoring the power components that have been turned off: camera module, ISP, VPU, and / or display screen, etc.

[0176] In some embodiments, such as Figure 12As shown, the wireless communication link has a continuous communication state. In the continuous communication state, the video image transmission efficiency between the first electronic device 100 and the second electronic device 200 is relatively high, so that the first electronic device 100 can receive the video image from the second electronic device 200 through the wireless communication link and display the video image on the main interface 20 of the first electronic device 100. When the first electronic device 100 hides the first video image 201 for more than a preset time and does not display the video image from the second electronic device 200 within the preset time, it indicates that the user may not use the video image from the second electronic device 200 for some time. Therefore, a standby control instruction is sent to the second electronic device 200. On the one hand, the standby control instruction is used to instruct components such as the camera in the second electronic device 200 to turn off. On the other hand, the standby control instruction is also used to instruct the second electronic device 200 to change the wireless communication link from the continuous communication state to the periodic sleep communication state. In the periodic sleep communication state, the wireless communication link includes alternating sleep phases and wake-up phases. Data can be transmitted during the wake-up phase, that is, data transmission can be intermittently realized to save power consumption while ensuring the basic information transmission function of the wireless communication link.

[0177] When the continuous duration of the wireless communication link in the periodic sleep communication state reaches a first preset duration, a Bluetooth Low Energy (BLE) connection is established between the first electronic device 100 and the second electronic device 200, and the wireless communication link is disconnected. For example, the first electronic device 100 and the second electronic device 200 determine to disconnect the wireless communication link (i.e., the WiFi link) when the continuous duration in the periodic sleep communication state reaches the first preset duration through an inactivity timer. That is, when the inactivity timer times out, the wireless communication link is disconnected to reduce power consumption. However, to ensure that the first electronic device 100 and the second electronic device 200 can still maintain communication after the wireless communication link is disconnected, a BLE connection can be established between the two to implement functions such as instruction transmission.

[0178] As Figure 11 and Figure 13 As shown, after the first electronic device 100 sends a standby control instruction to the second electronic device 200, the above method further includes: the first electronic device 100 executes the first standby recovery process S1 or the second standby recovery process S2. Among them, both the first standby recovery process S1 and the second standby recovery process S2 include the process in which the first electronic device 100 receives a third user operation and the first electronic device 100 displays the first video image 201 on the main interface 20 according to the third user operation.

[0179] As Figure 11As shown, in the first standby recovery process S1, the third user operation is a standby recovery operation. That is, the first standby recovery process S1 includes: Step 1018: The first electronic device 100 receives the standby recovery operation; The first electronic device 100, according to the standby recovery operation, executes Step 1021: Display the first video image 201 on the main interface 20.

[0180] As Figure 13 shown, the second standby recovery process S2 includes:

[0181] Step 1007: The first electronic device 100 receives the third user operation;

[0182] The first electronic device 100, according to the third user operation, executes Step 1021: Display the first video image 201 on the main interface 20;

[0183] The second standby recovery process S2 further includes: Before receiving the third user operation, execute Step 1018: The first electronic device 100 receives the standby recovery operation.

[0184] As Figure 11 and Figure 13 shown, before the process of displaying the first video image 201 on the main interface 20, the first standby recovery process S1 and the second standby recovery process S2 further include:

[0185] The first electronic device 100, according to the standby recovery operation, executes Step 1019: Determine whether the wireless communication link is in a periodic sleep communication state or in a disconnected state when the standby recovery operation is received;

[0186] As Figure 14 shown, if the standby recovery operation is received when the wireless communication link is in a periodic sleep communication state, then execute Step 10201: Send a standby recovery control instruction to the second electronic device 200 through the wireless communication link. This standby recovery control instruction is used to instruct the second electronic device 200 to restore the wireless communication link to a continuous communication state. In this case, there is no need to establish a BLE connection, and since the wireless communication link is not disconnected, the wireless communication link can be quickly restored to a continuous communication state;

[0187] As Figure 12As shown, if a standby resume operation is received when the wireless communication link is disconnected, step 10202 is executed: sending a standby resume control instruction to the second electronic device 200 via a low-power Bluetooth (BLE) connection. The standby resume control instruction is used to instruct the second electronic device 200 to restore the wireless communication link to a continuous communication state. At the same time, the BLE connection can be disconnected to save power. Based on the standby resume control instruction, since the wireless communication link has been disconnected before, authentication needs to be performed first, and only after successful authentication can the wireless communication link be restored to a continuous communication state.

[0188] After the wireless communication link is restored to a continuous communication state, the first electronic device 100 can receive video images from the second electronic device 200 via the wireless communication link, and then can execute step 1021 according to the standby resume operation: displaying the first video image 201 on the main interface 20. In the first standby resume process S1, the sending of the standby resume control instruction and the display of the first video image 201 can be triggered by one standby resume operation; while in the second standby resume process S2, the sending of the standby resume instruction is triggered by the standby resume operation, and the display of the first video image 201 is triggered by another third user operation. Therefore, in the second standby resume process S2, the standby resume operation can be set as a pre-operation of the third user operation, that is, the standby resume instruction can be sent in advance before the user executes the third user operation. At this time, the wireless communication link will be restored in advance, and the components of the second electronic device that have been turned off will be restored. Then, when the third user operation is received, the first video image 201 from the second electronic device will be displayed on the main interface 20 to improve the response speed of displaying the first video image 201.

[0189] For example, in the first standby resume process S1, the third user operation is the standby resume operation, that is, the standby resume operation includes a click operation on an operation control (such as a floating ball). In addition, the third user operation can also include a first swipe gesture operation on a preset position 30. As Figure 11 shown, after step 1017, when the first electronic device receives a click operation on the floating ball or a first swipe gesture operation on the preset position 30 by the user, the process from step 1019 to step 1021 is executed to restore the display of the first video image 201.

[0190] For example, in the second standby resume process S2, the standby resume operation includes a touch operation on the preset position 30. Assume that the preset position 30 is the area to be displayed corresponding to the first video image. As Figure 13As shown, after step 1017, when the first electronic device receives a touch operation by the user on the preset position 30, steps 1019 to 10202 are executed to send a standby recovery control instruction to the second electronic device. When the first electronic device receives a first swipe gesture operation by the user on the preset position 30, step 1021 is executed to resume the display of the first video image 201. When the user performs the first swipe gesture operation on the preset position 30, the preset position 30 must be touched first. That is to say, when the user performs the third user operation, the process of sending the standby recovery operation instruction will inevitably be pre-triggered due to the pre-operation of the third user operation, and then the first video image 201 is displayed according to the third user operation.

[0191] It should be noted that in the shooting method of the multi-camera shooting system in the embodiments of the present application, the broadcast period interval of the BLE connection used is adjusted to be shorter than the broadcast period in other processes. For example, in the process of using BLE to implement intelligent home appliance control, the broadcast period interval of the BLE connection is 200 ms, while in the shooting method of the multi-camera shooting system in the embodiments of the present application, the broadcast period interval of the BLE connection can be adjusted to 50 ms, so that the instructions sent to the second electronic device through the BLE connection during the shooting process can be quickly responded to.

[0192] In some other embodiments, as Figure 15 shown, the standby control instruction is used to instruct the second electronic device to change the wireless communication link from the continuous communication state to the first periodic sleep communication state. In the first periodic sleep communication state, the power consumption is lower than that in the continuous communication state; when the duration of the wireless communication link in the first periodic sleep communication state reaches the first preset duration at the first electronic device, the wireless communication link is changed to the second periodic sleep communication state. The sleep cycle of the first periodic sleep communication state is less than the sleep cycle of the second periodic sleep communication state. By changing the wireless communication link to the second periodic sleep communication state, the power consumption can be further reduced.

[0193] Specifically, as Figures 15 to 18 shown, after sending the standby control instruction to the second electronic device, the above method further includes: the first electronic device executes the third standby recovery process S3 or the fourth standby recovery process S4; both the third standby recovery process S3 and the fourth standby recovery process S4 include the above process of receiving the third user operation and displaying the first video image 201 on the main interface 20 according to the third user operation.

[0194] As Figure 16As shown, in the third standby recovery process S3, the third user operation is a standby recovery operation; that is, the third standby recovery process S3 includes: Step 1018: Receive a standby recovery operation; according to the standby recovery operation, execute Step 1021. Step 1021: Display the first video image 201 on the main interface 20.

[0195] As Figure 17 shown, the fourth standby recovery process S4 includes:

[0196] Step 1007: Receive the third user operation;

[0197] According to the third user operation, execute Step 1021. Step 1021: Display the first video image 201 on the main interface 20;

[0198] The fourth standby recovery process S4 further includes: Before receiving the third user operation, execute Step 1018: Receive a standby recovery operation.

[0199] As Figure 16 and Figure 17 shown, before the process of displaying the first video image 201 on the main interface 20, the third standby recovery process S3 and the fourth standby recovery process S4 further include:

[0200] According to the standby recovery operation, execute Step 10201: Send a standby recovery control instruction to the second electronic device through a wireless communication link. The standby recovery control instruction is used to instruct the second electronic device to restore the wireless communication link to a continuous communication state.

[0201] After the wireless communication link is restored to the continuous communication state, the first electronic device 100 can receive video images from the second electronic device 200 through the wireless communication link, and then can execute Step 1021 according to the standby recovery operation. Step 1021: Display the first video image 201 on the main interface 20.

[0202] For example, in the third standby recovery process S3, the third user operation is a standby recovery operation, that is, the standby recovery operation includes a click operation on an operation control (such as a floating ball). In addition, the third user operation can also include a first swipe gesture operation on a preset position 30. As Figure 16 shown, after Step 1017, when the first electronic device receives a click operation on the floating ball or a first swipe gesture operation on the preset position 30 by the user, it executes the process from Step 10201 to Step 1021 to restore the display of the first video image 201.

[0203] For example, in the fourth standby recovery process S4, the standby recovery operation includes a touch operation on the preset position 30. Assume that the preset position 30 is the area to be displayed corresponding to the first video image. AsFigure 17 As shown, after step 1017, when the first electronic device receives a touch operation by the user on the preset position 30, step 10201 is executed to send a standby recovery control instruction to the second electronic device. When the first electronic device receives a first sliding gesture operation by the user on the preset position 30, step 1021 is executed to resume the display of the first video image 201. When the user performs the first sliding gesture operation on the preset position 30, the user will necessarily touch the preset position 30 first. That is to say, when the user performs the third user operation, the process of sending the standby recovery operation instruction will necessarily be pre-triggered due to the pre-operation of the third user operation, and then the first video image 201 will be displayed according to the third user operation.

[0204] In Figure 16 and Figure 17 the embodiments shown, the wireless communication link can apply Figure 18 the data transmission process shown. The wireless communication link includes multiple synchronization cycles. The duration of a synchronization cycle is, for example, 524 ms. Each synchronization cycle includes a discovery window and a data transmission phase. The duration of the discovery window is, for example, 16 ms. In each discovery window, the master device involved in the wireless communication link will send synchronization beacons Sync Beacons. The slave device involved in the wireless communication link only needs to receive the Sync Beacons to achieve synchronization with the master device. Therefore, the power consumption of the slave device is lower than that of the master device. Therefore, in the embodiments of the present application, if the multi-camera shooting system includes a mobile phone and a wireless shooting device, the mobile phone is used as the master device and the wireless shooting device is used as the slave device to reduce the power consumption of the wireless shooting device. As Figure 15 and Figure 18 shown, in the continuous communication state, data is transmitted in the data transmission phase of each synchronization cycle; in the first periodic sleep communication state and the second periodic sleep communication state, the wireless communication link includes alternating sleep phases and wake-up phases. Data can be transmitted in the data transmission phase of the wake-up phase, and data cannot be transmitted in the data transmission phase of the sleep phase. Among them, the duration of the sleep phase of the first periodic sleep communication state is less than the duration of the sleep phase of the second periodic sleep communication state.

[0205] In some embodiments, when the second electronic device enters the standby mode, the auxiliary light on the second electronic device can be controlled to flash to remind the user that this camera position is still in use in the standby mode of the multi-camera shooting system, but components such as the lens of the second electronic device are not used. It can be understood that other methods can also be used to remind the user, not limited to the flashing of the auxiliary light. Therefore, the method for reminding the user that the camera position is working in the standby mode is not limited in this embodiment. As Figure 19As shown, taking a specific scenario as an example, where the first electronic device 100 and the second electronic device 200 are mobile phones, and the third electronic device 300 is a wireless shooting device. When the first electronic device 100 only displays the picture taken by the first electronic device 100 itself, auxiliary lights 900 are respectively provided on the second electronic device 200 and the third electronic device 300. The first electronic device 100 sends a standby control instruction to the second electronic device 200 and the third electronic device 300, causing the screen and camera of the second electronic device 200 to be turned off, and the camera of the third electronic device 300 to be turned off. The auxiliary lights on the second electronic device 200 and the third electronic device 300 flash to prompt the user that the device is still in use under multi-camera standby, but the camera of the device is not being used.

[0206] In some embodiments, as Figure 20 shown, the first electronic device 100 receives a touch operation or a click operation by the user on a preset position 30, and according to this operation, sends a standby recovery instruction to the second electronic device. After sending the standby recovery control instruction to the second electronic device, the above method further includes:

[0207] The first electronic device 100 displays a transition image 209 at the preset position 30 according to a third user operation, such as a first swipe gesture operation on the preset position 30.

[0208] The process of the first electronic device 100 displaying the first video image on the main interface according to the third user operation includes: The first electronic device 100, according to the third user operation, when the first electronic device receives the first video image from the second electronic device through a wireless communication link restored to the continuous communication state, replaces the transition image 209 with the first video image 201, that is, displays the restored first video image 201 on the first electronic device 100, and the restored first video image 201 comes from the second electronic device.

[0209] For example, on the basis of what is shown in Figure 11 or Figure 16 shown, the third user operation is a standby recovery operation. That is, the same user operation can be used to indicate the restoration of the wireless communication link, the restoration of the components of the second electronic device that have been turned off, and the restoration of the first video image 201 displayed on the first electronic device. After sending the standby recovery control instruction to the second electronic device, the method further includes:

[0210] The first electronic device 100 displays a transition image at the preset position according to the standby recovery operation;

[0211] The first electronic device 100, according to the standby resume operation, when the first electronic device receives the first video image from the second electronic device through a wireless communication link restored to the continuous communication state, replaces the transition image 209 with the first video image 201. That is to say, Figure 11 or Figure 16 On the basis shown, the step of displaying the transition image is added, and step 1021 is replaced with the process of "replacing the transition image 209 with the first video image 201".

[0212] For example, the third user operation, that is, the standby resume operation is the first swipe gesture operation acting on the preset position 30. After the first electronic device 100 hides the first video image 201 and sends a standby control instruction to the second electronic device, when the user hopes to resume the display of the first video image 201, the first swipe gesture operation acting on the preset position 30 can be performed on the first electronic device 100. Since the video image to be displayed is the video image of the secondary camera position, the secondary camera position needs to transmit the video image to the first electronic device 100, and there will be a time difference between the first swipe gesture operation and the display of the video image of the secondary camera position on the main interface. During this time difference, the first electronic device 100, according to the first swipe gesture operation, displays the pre-stored transition image 209 at the preset position 30; when the second electronic device and the wireless communication link are restored from the low-power state, and the first electronic device 100 receives the first video image 201, the transition image 209 is replaced with the first video image 201, so as to realize the restoration of the display of the first video image 201 on the first electronic device 100, and solve the problem of image display delay. The transition image can be a dynamic effect of a blurred and rotating picture, or other types of fixed images. The type of the transition image is not limited in this embodiment.

[0213] Similarly, for example, in Figure 13 or Figure 17 On the basis shown, the standby resume operation and the third user operation are different operations. For example, the standby resume operation is a touch operation or a click operation acting on the preset position 30. For example, after the second electronic device enters the standby mode, if the user needs to use the video image from the second electronic device, it can be triggered by a touch operation on the preset position 30 of the first electronic device. After sending a standby resume control instruction to the second electronic device, the method further includes:

[0214] The first electronic device 100, according to the third user operation, displays a transition image at the preset position;

[0215] The first electronic device 100, according to the standby resume operation, when the first electronic device receives the first video image from the second electronic device through a wireless communication link restored to the continuous communication state, replaces the transition image 209 with the first video image 201. That is to say, inFigure 13 or Figure 17 On the basis shown, the step of displaying a transition image is added, and the process of replacing step 1021 with "replacing the transition image 209 with the first video image 201" is carried out.

[0216] Specifically, for example, the standby recovery operation is a touch operation or a click operation on the preset position 30 of the first electronic device 100, and the third user operation is a first swipe gesture operation acting on the preset position 30. After the first electronic device 100 hides the first video image 201 and sends a standby control instruction to the second electronic device, when the user hopes to resume the display of the first video image 201, click on the preset position 30 of the first electronic device 100 and perform the first swipe gesture operation. In this process, the standby recovery operation and the third user operation are sequentially executed. When receiving the standby recovery operation of the user clicking on the preset position 30, a standby recovery control instruction will be sent to the second electronic device to resume the standby state in advance; after receiving the first swipe gesture operation, since the video image to be displayed is that of the secondary camera position, then the secondary camera position needs to transmit the video image to the first electronic device 100, and there will be a time difference between the first swipe gesture operation and the display of the video image of the secondary camera position on the main interface. During this time difference, the first electronic device 100 displays the pre-stored transition image 209 at the preset position 30 according to the first swipe gesture operation; when the second electronic device and the wireless communication link are restored from the low-power state, and the first electronic device 100 receives the first video image, the transition image 209 is replaced with the first video image 201 to achieve the restoration of the display of the first video image 201 on the first electronic device 100, solving the problem of image display delay.

[0217] In addition, different secondary camera positions can have different preset positions on the first electronic device. For example, the second electronic device has a corresponding preset position in the upper left corner of the screen of the first electronic device, and the third electronic device has a corresponding preset position in the upper right corner of the screen of the first electronic device. Assume that the first electronic device currently only displays the second video image 202 and no other video images, and the second video image 202 is a video image taken by the first electronic device itself. At this time, both the second electronic device and the third electronic device can be in the standby mode.

[0218] For example, in the first scenario, when the user clicks on the upper left corner or swipes the screen from the upper left corner to the lower right corner, as the third user operation, the first electronic device will send a standby recovery control instruction to the second electronic device.

[0219] For example, in the second scenario, when the user clicks on the upper right corner, or swipes the screen from the upper right corner to the lower left corner, the first electronic device will send a standby recovery control instruction to the third electronic device. The following describes an embodiment in one scenario in combination with the process of controlling between the first electronic device and the second electronic device based on a wireless communication link: In the initial state, the first electronic device only displays the second video image 202, and the second video image 202 is a video image captured by the first electronic device itself; afterwards, the user controls the first electronic device through a touch event. If the touch event involves the screen control of the remote second electronic device, for example, the user controls the first video image from the second electronic device to be displayed on the first electronic device, it is forwarded to the VirtualCameraAgent of the second electronic device through CameraHAL for control, so that the video image captured by the second electronic device is transmitted to the first electronic device and forms the first video image displayed on the main interface.

[0220] The following describes the embodiments of the present application through two specific examples.

[0221] As Figure 21 shown, two mobile phones supporting multi-camera shooting are respectively used as the first electronic device 100 and the second electronic device 200. The display and hiding of video images can be realized by swiping in and out operations on a preset position 30 on the screen of the first electronic device 100. For example, the main interface of the first electronic device 100 can display the second video image 202 captured by the first electronic device 100 itself. At this time, the second video image 202 is used as the recording screen. The swiping out operation of swiping the screen to the right on the preset position 30 can make the first video image 201 captured by the second electronic device 200 be displayed on the main interface of the first electronic device 100. The video switching operation can switch the first video image 201 and the second video image 202 in the main interface, so that the first video image 201 is switched to the recording screen. At this time, the swiping in operation of swiping the screen to the left on the preset position 30 can hide the second video image 202. In addition, picture-in-picture recording can also be realized. If the first electronic device 100 hides the first video image 201 and does not use the video image of the second electronic device 200, the second electronic device 200 can choose to enable the low-power mode; it can also choose not to enable the low-power mode. For the control transmission of the second electronic device 200, the above-mentioned priority optimization strategy can be used to reduce the latency of control operations on the first electronic device 100.

[0222] As Figure 22 shown, a mobile phone supporting multi-camera shooting is networked with the first electronic device 100 and the fourth electronic device 400, and the fourth electronic device 400 is a shooting device. The specific process and principle can be the same as the above Figure 21The content involved is similar. The difference is that Figure 22 the first video image 201 in Figure 22 comes from the fourth electronic device 400. A low-power indicator light and a startup indicator light can be set on the fourth electronic device 400. When the first electronic device 100 does not use the video image of the fourth electronic device 400, the low-power indicator light of the fourth electronic device 400 flashes, indicating that networking has been established but shooting or previewing is not in use. When the first video image 201 shown by sliding out is an image from the fourth electronic device 400, the startup indicator light of the fourth electronic device 400 flashes, indicating that the device has been enabled for shooting or previewing.

[0223] The embodiment of the present application further provides a shooting device for a multi-camera shooting system, which is applied to the first electronic device. The first electronic device is the main camera position of the multi-camera shooting system. The multi-camera shooting system further includes at least one auxiliary camera position. The device includes: an interface display module, configured to display a main interface, and the main interface includes a first video image; an operation receiving module, configured to receive a first user operation in the video shooting mode; the interface display module is further configured to, according to the first user operation, display a second video image on the main interface. The first video image comes from the main camera position or the auxiliary camera position, and the second video image comes from the auxiliary camera position, that is, the first video image and the second video image are video images provided by different camera positions in the multi-camera shooting system; the operation receiving module is further configured to receive a video switching operation, and the video switching operation is directed to the second video image; a video switching module, configured to switch the first video image and the second video image according to the video switching operation.

The specific process and principle are the same as those of the above embodiments and will not be elaborated here.

[0224] It should be understood that the division of the shooting devices in the above multi-camera shooting system is only a division of logical functions. In actual implementation, they can be fully or partially integrated into a physical entity, or physically separated. And these modules can all be implemented in the form of software called by processing elements; they can also all be implemented in the form of hardware; or some modules can be implemented in the form of software called by processing elements, and some modules can be implemented in the form of hardware. For example, any one of the interface display module, the operation receiving module, and the video switching module can be a separately established processing element, or can be integrated into the shooting device, for example, implemented by being integrated into a certain chip of the shooting device. In addition, it can also be stored in the memory of the shooting device in the form of a program, and the functions of the above various modules can be called and executed by a certain processing element of the shooting device. The implementation of other modules is similar. In addition, all or part of these modules can be integrated together or can be independently implemented. The processing element mentioned here can be an integrated circuit with the ability to process signals. In the implementation process, each step of the above method or the above various modules can be completed through the integrated logic circuit in the processor element or the instructions in the form of software.

[0225] For example, the shooting device can be one or more integrated circuits configured to implement the above method, such as: one or more application specific integrated circuits (ASICs), or, one or more digital signal processors (DSPs), or, one or more field programmable gate arrays (FPGAs), etc. Again, when a certain module above is implemented in the form of a processing element scheduling program, the processing element can be a general-purpose processor, such as a central processing unit (CPU) or other processors that can call programs. Again, these modules can be integrated together and implemented in the form of a system-on-a-chip (SOC).
