Referring to fig. 3, fig. 3 is a flowchart of a photographing method of a multi-camera photographing system according to an embodiment of the present application, which is applied to a first electronic device 100 of the multi-camera photographing system shown in fig. 1, where the first electronic device 100 is a host of the multi-camera photographing system, as shown in fig. 3, the photographing method may include:
Step 1000, as shown in fig. 4a, the first electronic device displays a main interface 20, the main interface 20 is an interface watched by a host or a recorder, the main interface 20 includes a first video image 201, and the first video image 201 is, for example, a hand-held bicycle frame;
Step 1001, a first electronic device receives a first user operation in a video shooting mode;
Step 1002, as shown in fig. 4b, according to a first user operation, the first electronic device displays a second video image 202 on the main interface 20, where the second video image 202 is, for example, a sitting frame, the first video image 201 and the second video image 202 may be displayed on the main interface 20 in an overlapping manner, a display area of the first video image 201 may be larger than a display area of the second video image 202, the second video image 202 may be displayed on an upper layer of the first video image 201, the first video image 201 is from a main machine position or an auxiliary machine position, and the second video image 202 is from an auxiliary machine position, that is, the first video image 201 and the second video image 202 are video images provided by different machine positions in the multi-machine position shooting system;
At this time, the first video image 201 is a recorded picture or a live broadcast picture, that is, a picture in which the first video image 201 is recorded and saved or transmitted to the server for live broadcast, that is, a video image finally presented to the viewer, the second video image 202 is a non-recorded picture, or a broadcast guide picture, that is, the second video image 202 is only used for the anchor to watch the preview and is not presented to the viewer to watch, if the second video image 202 is from the second electronic device, when the second video image 202 is displayed on the main interface 20, the first electronic device sends an instruction to the second electronic device to acquire the second video image, and the second electronic device transmits the second video image captured to the first electronic device according to the instruction.
Step 1003, the first electronic device receives a video switching operation, wherein the video switching operation is aimed at the second video image 202, for example, the user clicks on the sitting screen in the main interface 20;
In step 1004, as shown in fig. 4c, the first electronic device switches the first video image 201 and the second video image 202 according to the video switching operation, that is, switches the first video image 201 to the original display area of the second video image 202, switches the second video image 202 to the original display area of the first video image 201, after switching, the first video image 201 becomes a guide frame only used for the main broadcasting to watch the preview, and is no longer presented to the audience to watch, and the second video image 202 becomes a recording frame or a live broadcast frame, and is presented to the audience to watch, at this time, the first video image 201 may be displayed on the upper layer of the second video image 202.
For example, the user clicks the sitting-up screen in the main interface 20 shown in fig. 4b, the first electronic device switches the video image, and the main interface 20 is switched from the one shown in fig. 4b to the one shown in fig. 4c, and the video switching operation functionally switches the sitting-up screen to the recording screen and the hand-held bicycle screen to the guiding screen, in addition to the switching of the video image in the interface.
Specifically, after the first electronic device (the host site) and the auxiliary site are networked successfully, the first electronic device 100 enters a shooting application, where the application to be shot includes, but is not limited to, shooting or live broadcasting, and may be a camera application on a mobile phone or other applications supporting a multi-site system. When the first electronic device 100 enters the photographing application and is in the video photographing mode, the user may see the first video image 201 of the main interface 20, and the user may perform a first user operation to cause the second video image 202, which is a conductive screen, to be displayed on the main interface 20 so that the video image from one station may be viewed while the video image from another station is being viewed on the main interface 20.
When the user wishes to switch the second video image 202 to a recorded picture, a video switching operation is performed. It should be noted that, the main interface 20 may include a plurality of second video images 202, for example, a user may see, through the main interface 20, a plurality of second video images 202 provided by a plurality of machine positions, and the user may select a certain path of second video image to be recorded from the main interface 20 to switch with the first video image 201, so as to record the path of second video image 202, that is, select, through a video switching operation, to switch the second video image 202 to be recorded from the main interface 20 with the first video image 201. By switching the video images, the flexibility of video shooting is improved. In addition, the first video image 201 of the original main interface 20 is switched to the guide screen so that the anchor continues to watch the first video image 201 in the main interface 20.
Illustratively, the main interface 20 includes an operation control, such as a video recording button, a pause button, a hover ball, a zoom button, etc., where the hover ball may be dragged to any position, and the hover ball is used to trigger a second video image to be displayed on the main interface, for example, the first user operation includes a click operation on the operation control (e.g., the hover ball), or the first user operation includes a first sliding gesture operation on the preset position 30, for example, as shown in fig. 4b, where the preset position 30 is a display area corresponding to the second video image 202 before the video switch operation, where the video switch operation includes a single click operation on the second video image 202 before the video switch operation, and the single click operation may be a fast single click operation or a long click operation. For example, when the user performs the right swipe gesture operation at the preset position 30 on the lower left side of the main interface 20 as shown in fig. 4a, the main interface 20 becomes as shown in fig. 4b, and the second video image 202 is displayed. For another example, when the first electronic device displays a hover ball, after the user clicks the hover ball as shown in fig. 4a, the main interface 20 may change to display a second video image 202 as shown in fig. 4 b. The first user operation may also be other types of user operations, such as virtual key operation, physical key operation, and the like, and the form of the first user operation is not limited in this embodiment.
For example, the video switching operation may include a long press operation of the second video image 202 by the user. For example, when the user presses the second video image 202 shown in fig. 4b for a long time, the main interface 20 becomes as shown in fig. 4c, and the first video image 201 and the second video image 202 are switched, and at this time, if the user presses the first video image 201 for a long time, the first video image 201 and the second video image 202 are switched again, that is, the main interface 20 is changed back to as shown in fig. 4 b. The video switching operation may also be other forms of user operation, such as a virtual key operation, an entity key operation, etc., for example, the main interface 20 may include a video switching control, and the video switching operation may include an operation acting on the video switching control.
Further, when the user does not need to use the non-recorded picture, the second video image 202 shown in fig. 4b may be hidden, or the first video image 201 shown in fig. 4c may be hidden, so that the user may better watch a video image being recorded.
As shown in fig. 4a to 4d and fig. 5a, on the basis of the embodiment shown in fig. 3, after the process of switching the first video image 201 and the second video image 202 by the first electronic device in step 1004 according to the video switching operation, the shooting method may further include:
step 1005, the first electronic device receives a second user operation;
Step 1006, the first electronic device hides the first video image 201 on the main interface according to the second user operation, i.e. the screen display state of the first electronic device is changed from fig. 4c to fig. 4d according to the second user operation, in which case the main interface 20 only displays the second video image 202 after hiding the first video image 201.
When the user again needs the first video image 201 to be displayed, steps 1007 and 1008 may also be performed, step 1007 being receiving a third user operation, step 1008 being displaying the first video image 201 on the main interface 20 according to the third user operation. The non-recording picture is displayed or hidden according to the requirement, so that the flexibility of video shooting is improved. If the first video image 201 is from the second electronic device, when the first electronic device hides the first video image 201 at the main interface, there may be two cases for the second electronic device, where one case is that the second electronic device still transmits the first video image to the first electronic device, so that when the first electronic device can quickly resume displaying the first video image, the other case is that the second electronic device receives an instruction from the first electronic device, and does not transmit the first video image to the first electronic device according to the instruction, so as to save power consumption, but if the first electronic device needs to resume displaying the first video image, the first electronic device needs to transmit an instruction for resuming displaying the first video image to the second electronic device, and the second electronic device receives the instruction and resumes transmitting the first video image to the first electronic device according to the instruction. If the second electronic device is a mobile phone, the first video image is hidden in the first electronic device, and the screen of the second electronic device can always display the first video image or simultaneously hide the first video image.
The flowchart shown in fig. 5b is another photographing procedure in parallel with the flowchart shown in fig. 5a, and the photographing method further includes, after the first electronic device displays the second video image and before the first electronic device receives the video switching operation, i.e., after step 1002 and before step 1003, receiving a second user operation, hiding the second video image at the main interface according to the second user operation even if the interface shown in fig. 4b becomes the interface shown in fig. 4a, receiving a third user operation, displaying the second video image at the main interface according to the third user operation even if the interface shown in fig. 4a is restored to the interface shown in fig. 4 b. Steps 1003 and 1004 may then be performed to effect video switching, changing the interface shown in fig. 4b to the interface shown in fig. 4 c.
That is, in the flow shown in fig. 5a, the user conceals the first video image 201 as a non-recorded picture after performing the video switching operation, in the flow shown in fig. 5b, the user conceals the second video image 202 as a non-recorded picture, and can view the first video image 201 in a larger picture through the main interface 20, and when the video switching is required, the user resumes the display of the second video image 202 by performing the third user operation, and then performs the video switching operation.
In addition, in the flow shown in fig. 5a and 5b, the third user operation may be the same as the first user operation described above or may be different from the second user operation described above.
Illustratively, the operation control (e.g., a hover ball) is used to trigger hiding the first video image at the main interface and hiding the first video image at the main interface, e.g., the second user operation and the third user operation include a click operation on the operation control (e.g., a hover ball), and further, the third user operation may further include a first swipe gesture operation on the preset position 30, the second user operation may include a second swipe gesture operation on the preset position 30, and the first swipe gesture operation and the second swipe gesture operation may be opposite-direction swipe gesture operations, e.g., 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 shown in fig. 4c, or clicks the hover ball, the first video image 201 may be hidden, and then the main interface 20 may become as shown in fig. 4d, and if the user performs a right swipe gesture operation at the preset position 30 as shown in fig. 4d, or clicks the hover ball, the main interface 20 may become as shown in fig. 4c, i.e., resume the display of the first video image 201. In addition, the second user operation and the third user operation may be other types of user operations, such as virtual key operation, physical key operation, and the like, and the forms of the second user operation and the third user operation are not limited in this embodiment.
The above embodiments are further described below based on fig. 4a to 4 d.
Referring to fig. 4a, a first video image 201 is displayed on the main interface 20 of the first electronic device, where the first video image 201 is a video image of one path provided by the first electronic device or an auxiliary unit.
The first video image 201 may be recorded, and when a user performs a video recording operation, for example, after the user clicks a video recording button, the first electronic device receives the video recording operation, stores data of the first video image 201, or transmits the data of the first video image 201 to a server for live broadcast, etc., the data of the video image is obtained by a machine location providing the video image and transmitted to the first electronic device, and the first electronic device stores the data after encoding processing.
It can be appreciated that, in order to make the first video image 201 displayed more clearly, the first video image 201 may be displayed on the main interface 20 in a full screen manner, or may be displayed on a middle screen or a small screen instead of the full screen manner, and specifically may be set according to the user requirement, and the size of the first video image 201 is not limited in this embodiment.
In addition, the first video image 201 is a video image provided by the first electronic device or the auxiliary device, if the display screen of the first electronic device is smaller, the main interface 20 may display only one path of first video images, if the display screen of the first electronic device is larger, the main interface 20 may also display multiple paths of first video images, where the multiple paths of first video images may come from different locations or come from different cameras of the same location, for example, when the main interface 20 displays two paths of first video images, the two paths of first video images may be vertically tiled or horizontally tiled and displayed in the main interface, and in a practical application scenario, the number of first video images displayed in the main interface may be set based on the screen size of the first electronic device.
See fig. 4b. After receiving the first user operation, a second video image 202 is displayed on the main interface 20, where the second video image 202 is a video image provided by the first electronic device or the auxiliary device, and the first video image 201 and the second video image 202 are video images provided by different devices.
It will be appreciated 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 is not set too large, and generally the display size of the second video image 202 is smaller than the display size of the first video image 201, and the resolution of the second video image 202 is smaller than the resolution of the first video image 201, when the video image of the auxiliary machine is the second video image 202, the first electronic device sends a video acquisition instruction to the auxiliary machine, and the auxiliary machine can transmit the video image with low resolution to the first electronic device, so as to reduce the transmission amount of data. If the first video image 201 is displayed in full screen, the second video image 202 may be displayed superimposed on the first video image 201, and if the first video image 201 is not displayed in full screen, the second video image 202 may be displayed superimposed on the first video image 201 or not. The size, position and positional relationship with the first video image are not limited in this embodiment.
In addition, when the display screen of the first electronic device is relatively large, the main interface 20 may include more than one path of second video images, for example, the main interface 20 may display two paths of second video images, where the two paths of second video images may be vertically tiled or horizontally tiled in a partial area of the main interface 20, and in a practical application scenario, the number of second video images 202 may be set based on the size of the display screen and the size of the main interface.
See fig. 4c. In the scenario shown in fig. 4b, after the first electronic device receives the video switching operation of the user, the video switching operation switches the display effects of the first video image 201 and the second video image 202 in the main interface 20 with respect to the second video image 202, as shown in fig. 4c, and at the same time, in the background, switches the first video image 201 to a non-recording picture and switches the second video image 202 to a recording picture.
In one possible implementation, one of the first video image and the second video image is from the second electronic device 200, the second electronic device 200 is one auxiliary unit of the multi-unit shooting system, the other of the first video image and the second video image is from the first electronic device 100 or the third electronic device 300, and the third electronic device 300 is the other auxiliary unit of the multi-unit shooting system. That is, in the scene shown in fig. 4b or fig. 4c, in combination with the multi-camera shooting system shown in fig. 1, in one possible shooting process, one of the first video image 201 and the second video image 202 is from the first electronic device 100 to be shot by itself, the other of the first video image 201 and the second video image 202 is from the second electronic device 200 to be shot, and in the other possible shooting process, one of the first video image 201 and the second video image 202 is from the second electronic device 200 to be shot, and the other of the first video image 201 and the second video image 202 is from the third electronic device 300 to be shot.
Referring to fig. 4d, fig. 4d is a schematic view of a scene of fig. 4c after the first electronic device conceals the first video image. After receiving the second user operation, as shown in fig. 4d, the main interface 20 hides the first video image, and at this time, the main interface 20 displays only the second video image 202.
In some embodiments, this may be accomplished by performing a set-top-off operation when the user needs to view other video images.
As shown in fig. 6, on the basis of the embodiment shown in fig. 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 photographing method may further include:
Executing step 1009, a first electronic device receiver position switching operation, wherein the position switching operation is aimed at the first video image 201;
Step 1010 is executed in which the first electronic device replaces the first video image 201 with the third video image 203 according to the machine position switching operation, where the first video image 201 and the third video image 203 are video images provided by different machine positions in the multi-machine position shooting system.
For example, a multi-camera shooting system includes three electronic devices. The second video image 202 of the main interface 20 in the first electronic device 100 is a video image captured by a camera of the first electronic device 100, for example, a sitting frame, before the receiver position switching operation, the second video image 202 of the main interface 20 in the first electronic device 100 is a video image captured by the second electronic device 200, for example, a hand-held bicycle frame, and the video image (for example, a landscape frame) captured by the third electronic device 300 is not yet displayed on the first electronic device 100, and after the receiver position switching operation, the hand-held bicycle frame of the main interface 20 of the first electronic device 100 is switched to the landscape frame according to the receiver position switching operation. I.e. to switch non-recorded pictures in the main interface 20 to video images provided by different sites.
When the user needs to switch the non-recording picture based on the machine position, a machine position switching operation may be performed, so that the user views video images provided by other machine positions through the main interface 20 of the first electronic device 100. When the first electronic device 100 receives the station switching operation, a video image of another station provided by the main station or the auxiliary station is displayed at a position of the non-recording screen. For example, the host and the auxiliary sites share four video images provided by the sites, wherein one video image provided by the site is a recorded picture of the host interface 20, the remaining three video images provided by the sites can be presented as non-recorded pictures of the host interface 20, if the current non-recorded picture only displays the video image provided by one site, and the video images provided by the two sites are not displayed on the host interface 20, a site switching operation is performed, the non-recorded picture of the host interface 20 is switched to the video image provided by the other site, and the video images provided by the three sites can be checked in turn by repeatedly performing the site switching operation. The video images which do not enter the main interface 20 of all the machine positions can be easily checked by the user through the machine position switching operation, so that the user can conveniently watch the video images of different machine positions.
Illustratively, the set-point switching operation includes a double-click operation on the first video image 201. For example, when the user double-clicks 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 machine, if the user continues double-clicking the third video image 203, the third video image 203 is switched to the video image of yet another machine, and so on, and once every double-click. The order of the machine position switching can be preset by the system. The machine position switching operation may also be other types of operations, such as virtual key operation, physical key operation, etc., for example, the main interface may include a machine position switching control, and the machine position switching operation may include an operation acting on the machine position switching control.
In the position switching process, different situations may exist for the second electronic device and the third electronic device, in the position switching process of the first electronic device, the second electronic device may continuously transmit the first video image to the first electronic device, the third electronic device may 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, in addition, in the position switching process, the first electronic device may also send an instruction to the second electronic device and the third electronic device, for example, the second electronic device receives the instruction from the first electronic device, and does not transmit the first video image to the first electronic device according to the instruction, so as to save power consumption, and the third electronic device receives the instruction from the first electronic device and resumes transmitting the third video image to the first electronic device according to the instruction. If the second electronic device and the third electronic device are mobile phones, in the process of switching the phone positions of the first electronic device, the screen of the second electronic device can always display the first video image, or after the first electronic device switches the first video image into the third video image, the second electronic device hides the first video image, the screen of the third electronic device can always display the third video image, or after the first electronic device switches the first video image into the third video image, the third electronic device starts to display the third video image.
In some embodiments, as shown in fig. 7, for example, when the second electronic device 200 is a mobile phone including a front camera and a rear camera as shown in fig. 2, the first video image in the main interface 20 of the first electronic device 100 is from the rear camera of the second electronic device 200, and in order to view the video image provided by the front camera of the second electronic device 200, the method may be implemented by a camera switching operation.
On the basis of the embodiment shown in fig. 3, 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 photographing method may further include:
Step 1011 is executed, wherein the first electronic device 100 receives a camera switching operation, the camera switching operation being directed to the first video image 201;
step 1012 is executed in which the first electronic device 100 replaces the first video image 201 with the fourth video image 204 according to the camera switching operation, where the first video image 201 and the fourth video image 204 are video images provided by different cameras in the same camera in the multi-camera shooting system.
For example, the multi-camera shooting system includes a first electronic device 100 and a second electronic device 200, wherein the second electronic device 200 has a front camera and a rear camera. Before the camera switching operation is received, the second video image 202 in the main interface 20 of the first electronic device 100 is a video image, such as a sitting picture, shot by the camera of the first electronic device 100, the first video image 201 in the main interface 20 of the first electronic device 100 is a video image, such as a hand-held bicycle picture, shot by the rear camera of the second electronic device 200, and at this time, the second electronic device 200 displays a hand-held bicycle picture shot by the rear camera, after the camera switching operation is received, the first electronic device 100 switches the first video image 201 in the main interface 20 to a fourth video image 204 according to the camera switching operation, and the fourth video image 204 is a self-shot picture shot by the front camera of the second electronic device 200. I.e. to switch non-recorded pictures of the main interface 20 in the first electronic device 100 to video images provided by different cameras in the same location.
When the user needs to switch the non-recorded picture of the main interface 20 in the first electronic device 100 to a video image provided by another camera at the same location, the camera switching operation may be performed. When the first electronic device 100 receives the camera switching operation, it switches the current non-recording picture in the main interface 20 to a video image provided by another camera with 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, the user can conveniently view the video images of different cameras, and the flexibility of video shooting is improved.
Illustratively, the camera switching operation includes a three-click operation on the first video image 201. For example, when the user clicks the first video image 201 of the main interface 20 three times, the first video image 201 may be switched to a video image provided by another camera in the same location, and if more than two cameras continue to click three times, the switching may be performed once every three times. The order in which the cameras are switched may be preset by the system. The camera switching operation may also be other types of operations, such as virtual key operation, physical key operation, and so on, for example, the main interface 20 may include a position switching control, and the position switching operation may include an operation acting on the position switching control.
In the process of camera switching, different situations may exist for the second electronic device, in the process of camera switching of the first electronic device, the second electronic device may 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, in addition, when the camera is switched, the first electronic device may also send an instruction to the second electronic device, for example, before the first electronic device receives the camera switching operation, the first electronic device and the second electronic device both display the first video image, when the first electronic device receives the camera switching operation, the second electronic device sends a response instruction to the second electronic device, and the second electronic device displays the fourth video image according to the instruction, and the first electronic device switches the first video image to the fourth video image. In addition, before the camera is switched, the second electronic device may not transmit the fourth video image to the first electronic device, and at this time, when the second electronic device receives the instruction of the first electronic device, the fourth video image may be transmitted to the first electronic device, so that the first electronic device performs the camera switching.
In some embodiments, in order to meet the diversified requirements of users for shooting videos, the expression mode of the videos is increased, and the picture-in-picture effect can also be increased in the recorded pictures.
As shown in fig. 8, on the basis of the embodiment shown in fig. 3, after the process of switching the first video image 201 and the second video image 202 by the first electronic device 100 according to the video switching operation, the photographing method may further include:
Step 1013 is performed in which the first electronic device 100 receives a picture-in-picture display operation for the first video image 201;
Step 1014 is performed in which the first electronic device 100 displays a fifth video image 205 at least partially surrounded by the second video image 202 on the main interface 20 according to the picture-in-picture display operation, the fifth video image 205 being identical to the first video image 201, the fifth video image 205 and the second video image 202 being recorded pictures or live pictures, i.e. superimposed pictures of the fifth video image 205 and the second video image 202 for presentation to a viewer for viewing.
For example, a picture-in-picture display operation including a drag operation on the first video image 201, a user holding the first video image 201 drag upward, will generate a fifth video image 205.
It will be appreciated that the display size of the fifth video image 205 is smaller than the display size of the second video image 202, and that the resolution of the fifth video image 205 is smaller than the resolution of the second video image 202, when the fifth video image 205 comes from a certain auxiliary station, the auxiliary station may transmit a video image of low resolution to the first electronic device to reduce the transmission amount of data.
When the user needs to display the pip effect in the recording screen, the pip display operation may be performed so that the main interface 20 of the first electronic device 100 displays 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, and the fifth video image 205 and the second video image 202 are overlapped to be the recording screen, that is, the fifth video image 205 and the second video image 202 are recorded as overlapped video images so as to be saved as the video screen of the pip effect, or transmitted to the server to be live broadcast, so as to form the live broadcast screen of the pip effect. The video image recording effect of the picture-in-picture increases the expression form of the video and improves the flexibility of video shooting.
For example, the picture-in-picture display operation may 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 drags it upward to the right, the fifth video image 205 identical to the first video image 201 is additionally displayed on the main interface 20. The pd display operation may also be other types of operations, such as virtual key operation, physical key operation, etc., for example, the main interface includes a pd control pd display operation may include an operation acting on the pd control, and the form of the pd display operation is not limited in this embodiment. In addition, for the fifth video image 205, it may be dragged in any area covered by the main interface 20.
Illustratively, the user may implement the position movement of the fifth video image 205 in the main interface 20 by dragging the fifth video image 205 in the main interface 20, and the user may select the position where the fifth video image 205 is placed according to the requirement, thereby improving the flexibility of video capturing.
Further, when the user does not need to display the fifth video image 205, the fifth video image 205 may be hidden to end the picture-in-picture display effect.
As shown in fig. 9, when the main interface 20 of the first electronic device 100 displays the fifth video image 205, the photographing method may further include:
Step 1015 is performed in which the first electronic device 100 receives a PIP hiding operation, which may include a drag operation on the fifth video image 205, such as a user holding the fifth video image 205 up and sliding out of the boundary of the main interface 20, hiding the fifth video image 205, i.e., the main interface 20 of the first electronic device 100 does not display the fifth video image.
At step 1016, first electronic device 100 conceals fifth video image 205 at main interface 20 in accordance with the picture-in-picture concealment operation.
It should be noted that, when the user no longer needs the pip effect, a pip hiding operation may be performed to hide the fifth video image 205. When the user again desires the pip display, the pip display operation may also be performed again to cause the fifth video image 205 to be displayed. The picture-in-picture effect is displayed or hidden as required, so that the flexibility of video shooting is improved.
For example, besides the drag operation, the pd hiding operation may be other types of operations, such as virtual key operation, physical key operation, etc., for example, the main interface includes a pd control, the third interface hiding operation may be an operation acting on the pd control, and the form of the third interface hiding operation is not limited in this embodiment.
It may be appreciated that, in fig. 8 and fig. 9, the superposition of the first video image 201 and the fifth video image 205 is a recording interface, when the user performs a video recording operation, for example, clicks a video recording key, the first electronic device 100 receives the video recording operation, stores video image data, where the video image data is video image data corresponding to a video image obtained by superposing the first video image 201 and the fifth video image 205, the video image data is acquired by a machine location providing the video image and is transmitted to the first electronic device 100, and the first electronic device 100 stores or transmits the video image data to a server live broadcast after performing an encoding process.
In some embodiments, the user may perform picture control on the video images displayed on the main interface 20 in the first electronic device 100, and may separately implement picture control on different video images, such as zooming, focusing, and so on. Accordingly, the main interface 20 in the first electronic device 100 may present a video image after the screen control. The implementation manner is that the first electronic device 100 transmits the picture control instruction to the corresponding machine position, the corresponding machine position adjusts the video image according to the picture control instruction, and the adjusted video image is transmitted to the first electronic device 100 for display.
In addition, in the video image capturing process, there are usually some special effects such as beautifying, and these effects may be directly implemented on the first electronic device for the video image, or the special effects control instruction may be transmitted to the corresponding auxiliary machine position of the video image, where the corresponding auxiliary machine position adjusts the video image according to the special effects control instruction, and the adjusted video image is transmitted to the first electronic device 100 for display. In addition, if the first electronic device 100 displays the fifth video image, that is, the picture-in-picture recording method is used, the same special effect control may be performed on the second video image and the fifth video image, or different special effect controls may be performed on the second video image and the fifth video image, respectively.
In some embodiments, when the user operates the video image displayed on the main interface 20 at the first electronic device 100 and the operated video image is a video image provided by the auxiliary machine site, the first electronic device 100 needs to send a shooting control instruction to the auxiliary machine site, so that the auxiliary machine site transmits the operated video image to the first electronic device 100 for display. In order to reduce the delay in image display, the photographing control instructions transmitted from the first electronic apparatus 100 to the auxiliary machine position all need to be transmitted with priority.
In some embodiments, as shown in fig. 1 and 3, it is assumed that in step 1002, the second video image is from the second electronic device 200, and the second electronic device 200 is a secondary unit of the multi-unit shooting system. The step 1002, the process of displaying the second video image 202 on the main interface 20 by the first electronic device 100 according to the first user operation includes:
Step 10021, the first electronic device 100 generates a data transmission control instruction according to the first user operation, where the data transmission control instruction carries a high-priority tag;
step 10022, the first electronic device 100 transmits the data transmission instruction to the second electronic device 200 based on the high priority;
the data transmission instruction is used for controlling the second electronic device 200 to transmit the second video image shot by the second electronic device back to the first electronic device 100;
Step 10023, the first electronic device 100 receives the second video image sent by the second electronic device 200;
at step 10024, the first electronic device 100 displays the second video image 202 on the main interface 20.
In addition, the above method may further include transmitting a focus control instruction or a zoom control instruction, etc., to the second electronic device 200 based on the high priority according to the user operation. When the first electronic device 100 and the second electronic device 200 communicate through WiFi, these shooting control instructions such as a data transmission control instruction, a focus control instruction, and a zoom control instruction are transmitted to the auxiliary station through WiFi to perform shooting control. Fig. 10 illustrates a schematic diagram of a transmission queue, where a media access control service data unit (MAC SERVICE DATA Units, MSDUs) is classified into a plurality of transmission queues VO, a_vo, a_vi, VI, BE, BK by a transmission queue and access class (access category) map, VO is Voice (Video), BE is Best effort (Best effort), BK is Background, and the transmission queues are classified into enhanced distributed channel access (enhanced distributed channelaccess, EDCA) queues, which include VO, VI, BE, and BK according to the priority. In order to make the operation experience of the user better, in the embodiment of the application, the data packets of the shooting control instructions carry high-priority labels, and the data packets carrying the high-priority labels are put into the EDCA queue of WiFi in a differentiated mode and transmitted to the second electronic device by adopting the high-priority queue (i.e. the VO queue in FIG. 10), and other control instructions except the shooting control instructions and the transmission data of the video images are placed in the default queue according to the protocol. The problem of communication delay between the first electronic equipment and the auxiliary equipment is reduced by transmitting the shooting control instruction to the second electronic equipment based on high priority.
In some embodiments, in order to reduce power consumption of each machine in the multi-machine shooting system, when a video image of a certain machine is not displayed on a main interface of the first electronic device, the corresponding machine may be controlled to enter a low-power consumption working state.
Fig. 11 is a flowchart of a shooting method of another multi-camera shooting system according to an embodiment of the present application, and based on the embodiment shown in fig. 1, before receiving a third user operation, for example, after step 1004, the first video image 201 is from the second electronic device 200, and the second electronic device 200 is an auxiliary camera of the multi-camera shooting system, where the shooting method may further include:
Step 1005, receiving a second user operation;
step 1006, hiding the first video image 201 at the main interface 20 according to the second user operation, wherein the specific process of steps 1005 and 1006 can refer to the descriptions related to fig. 5a and 5 b;
Step 1017, after the first video image 201 is hidden by the main interface 20, and 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, where the standby control instruction is used to instruct the second electronic device 200 to turn off or operate any component or any combination of components in a low power consumption mode, that is, the camera module, the image signal processor ISP, the video processor VPU, the display screen, and the wireless communication link, where the wireless communication link is used to transmit the video image from the second electronic device 200 to the first electronic device 100. The second electronic device 200, if receiving the standby control command, performs standby according to the standby control command, for example, turns off or switches any of the above components or combinations to operate in the low power consumption mode.
The machine position in the multi-machine position shooting system can be a mobile device or other wireless shooting devices, and can only rely on the electric quantity of the mobile device or other wireless shooting devices. For example, the second electronic device 200 may be a mobile phone, and the reduction of the shooting power consumption of the mobile phone needs to be considered, where the power consumption is reduced by turning off or controlling at least part of the components of the second electronic device 200 to operate in a low power consumption mode when the second electronic device 200 is not in use, so as to keep the low power consumption of the device, for example, controlling the second electronic device 200 to enter a standby mode. That is, for the multi-camera shooting system, if a video image of a certain camera is not displayed by the first electronic device 100, i.e., is not used by the first electronic device 100, the first electronic device 100 can control the corresponding camera to reduce power consumption by transmitting a standby control instruction thereto. In addition, for the first electronic device 100, if all the video images displayed by the first electronic device 100 come from the auxiliary units, that is, the first electronic device 100 does not display the video images shot by the first electronic device 100, the camera module of the first electronic device 100, the image signal processor ISP and other devices that do not affect the display can be controlled to be turned off or controlled to operate in the low power consumption mode. For example, the multi-camera shooting system includes a first electronic device 100 and a second electronic device 200, as shown in fig. 4c and fig. 4d, the second video image 202 is from a video image shot by the first electronic device 100, the first video image 201 is from the second electronic device 200, and when the first electronic device 100 hides the first video image 201 at 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 a standby mode, so as to save power consumption.
In addition, in one possible implementation, the user may re-control the display of the first video image 201 in a very fast time after hiding the first video image 201, so as to improve the situation that the second electronic device 200 needs to be frequently controlled to stand by and recover from the standby mode in this case, the step 1017 may be that after the first video image 201 is hidden by 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 the standby control instruction to the second electronic device 200 may include:
When the first electronic device 100 hides the first video image 201 at the main interface 20 for more than a preset time, 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. To avoid frequent awakening of the second electronic device 200 and the wireless communication link from the standby mode.
The first electronic device 100 may be provided with a detection module, configured to periodically detect a target location in a display screen of the first electronic device, where no video image is used in the display screen, and when the target location is detected, notify the target location to enter a standby mode, and turn off a corresponding device.
When the second electronic device 200 is at least partially turned off or controlled to operate in the low power mode, if the first electronic device 100 uses the video image of the second electronic device 200 again, the secondary station 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) quick recovery of the wireless communication link, and 2) quick recovery of the already-turned-off power components, such as the camera module, ISP, VPU, and/or display screen.
In some embodiments, as shown in fig. 12, the wireless communication link has a continuous communication state in which video image transmission efficiency between the first electronic device 100 and the second electronic device 200 is high, so that the first electronic device 100 receives the video image from the second electronic device 200 through the wireless communication link and displays the video image on the main interface 20 of the first electronic device 100, and when the first electronic device 100 hides the first video image 201 for more than a preset time and the first electronic device 100 does not display the video image from the second electronic device 200 for the preset time, it is indicated that the user may not use the video image from the second electronic device 200 for a period of time, and thus sends a standby control instruction to the second electronic device 200, where the standby control instruction is used to instruct the second electronic device 200 to turn off a component such as a camera in the second electronic device 200, and 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 dormant communication state, the wireless communication link comprises alternating dormant phases and wake-up phases, and the wake-up phases can transmit data, namely, data transmission can be intermittently realized, so that power consumption is saved, and meanwhile, the basic information transmission function of the wireless communication link is ensured.
When the duration of the wireless communication link in the periodic dormant communication state reaches a first preset duration, a bluetooth low energy (Bluetooth Low Energy, BLE) connection between the first electronic device 100 and the second electronic device 200 is established and the wireless communication link is disconnected. For example, the first electronic device 100 and the second electronic device 200 determine, by the inactivity timer, to disconnect the wireless communication link (i.e., the WiFi link) when the duration of the periodic dormant communication state reaches the first preset duration, that is, when the inactivity timer expires, disconnect the wireless communication link to reduce power consumption. However, to ensure that communication can still be maintained between the first electronic device 100 and the second electronic device 200 after the wireless communication link is broken, a BLE connection between the two may be established to implement functions such as command transmission.
As shown in fig. 11 and 13, after the first electronic device 100 sends the standby control instruction to the second electronic device 200, the method further includes the first electronic device 100 executing the first standby recovery procedure S1 or the second standby recovery procedure S2. The first standby recovery process S1 and the second standby recovery process S2 each include a process that 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.
As shown in fig. 11, in the first standby recovery procedure S1, the third user operation is a standby recovery operation, that is, the first standby recovery procedure S1 includes the steps 1018 that the first electronic device 100 receives the standby recovery operation, and the first electronic device 100 performs the step 1021 that the first video image 201 is displayed on the main interface 20 according to the standby recovery operation.
As shown in fig. 13, the second standby recovery process S2 includes:
Step 1007, the first electronic device 100 receives a third user operation;
The first electronic device 100 performs step 1021 of displaying the first video image 201 on the main interface 20 according to the third user operation;
The second standby recovery procedure S2 further includes executing step 1018, prior to receiving the third user operation, that the first electronic device 100 receives a standby recovery operation.
As shown in fig. 11 and 13, before the process of displaying the first video image 201 by the main interface 20, the first standby recovery process S1 and the second standby recovery process S2 further include:
The first electronic device 100 performs step 1019 of determining whether the wireless communication link is in a periodic sleep communication state or in a disconnected state when the standby resume operation is received according to the standby resume operation;
As shown in fig. 14, if a standby resume operation is received while the wireless communication link is in the periodic dormant communication state, step 10201 is performed in which a standby resume control instruction for instructing the second electronic device 200 to resume the wireless communication link to the continuous communication state is transmitted to the second electronic device 200 through the wireless communication link, in which case no BLE connection needs to be established and the wireless communication link can be quickly resumed to the continuous communication state since the wireless communication link is not disconnected;
as shown in fig. 12, if a standby resume operation is received while the wireless communication link is disconnected, step 10202 is performed to transmit a standby resume control instruction to the second electronic device 200 through the bluetooth low energy BLE connection, the standby resume control instruction being for instructing the second electronic device 200 to resume the wireless communication link to a continuous communication state while the BLE connection may be disconnected to save power consumption. Based on the standby recovery control instruction, since the wireless communication link has been disconnected before, authentication is required first, and after authentication is successful, the wireless communication link can be recovered to the continuous communication state.
After the wireless communication link is restored to the continuous communication state, the first electronic device 100 may receive the video image from the second electronic device 200 through the wireless communication link, and then may perform step 1021 of displaying the first video image 201 on the main interface 20 according to the standby restoring operation. In the first standby recovery procedure S1, the transmission of the standby recovery control instruction and the display of the first video image 201 can be triggered by one standby recovery operation, whereas in the second standby recovery procedure S2, the transmission of the standby recovery instruction is triggered by the standby recovery operation, and the display of the first video image 201 is triggered by another third user operation. Therefore, in the second standby recovery flow S2, a standby recovery operation may be set as a pre-operation of the third user operation, that is, a standby recovery instruction may be sent in advance before the user performs the third user operation, at this time, the wireless communication link may be recovered in advance, the components of the second electronic device that have been turned off may be recovered, and then, when the third user operation is received, the first video image 201 from the second electronic device may be displayed on the main interface 20, so as to improve the response speed of displaying the first video image 201.
For example, in the first standby recovery procedure S1, the third user operation is a standby recovery operation, that is, the standby recovery operation includes a click operation on an operation control (e.g., a hover ball), and in addition, the third user operation may further include a first swipe gesture operation on the preset position 30. As shown in fig. 11, after step 1017, when the first electronic device receives a click operation of the user on the hover ball or a first slide gesture operation on the preset position 30, the process from step 1019 to step 1021 is performed to resume the display of the first video image 201.
For example, in the second standby recovery process S2, the standby recovery operation includes a touch operation applied to the preset position 30, and assuming that the preset position 30 is a region to be displayed corresponding to the first video image, as shown in fig. 13, after step 1017, when the first electronic device receives the touch operation applied to the preset position 30 by the user, steps 1019 to 10202 are performed to implement sending a standby recovery control instruction to the second electronic device, and when the first electronic device receives the first sliding gesture operation applied to the preset position 30 by the user, step 1021 is performed to recover the display of the first video image 201. When the user performs the first sliding gesture operation on the preset position 30, the user must touch the preset position 30 first, that is, when the user performs the third user operation, the process of sending the standby resume operation instruction is triggered in advance due to the front operation of the third user operation, and then the first video image 201 is displayed according to the third user operation.
It should be noted that, in the photographing method of the multi-camera photographing system of the embodiment of the present application, the broadcast period interval of the BLE connection used is shortened relative to the broadcast period adjustment 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 200ms, and in the photographing method of the multi-camera photographing system of the embodiment of the present application, the broadcast period interval of the BLE connection can be adjusted to 50ms, so that in the photographing process, the instruction sent to the second electronic device through the BLE connection can be responded quickly.
In other embodiments, as shown in fig. 15, the standby control instruction is configured to instruct the second electronic device to change the wireless communication link from the continuous communication state to the first periodic dormant communication state, where power consumption is lower than that of the continuous communication state, and when the duration of the wireless communication link in the first periodic dormant communication state reaches a first preset duration, the first electronic device changes the wireless communication link to the second periodic dormant communication state, where the dormant period of the first periodic dormant communication state is smaller than that of the second periodic dormant communication state, and the power consumption can be further reduced by changing the wireless communication link to the second periodic dormant communication state.
Specifically, as shown in fig. 15 to 18, after sending the standby control instruction to the second electronic device, the method further includes the steps that the first electronic device executes a third standby recovery procedure S3 or a fourth standby recovery procedure S4, wherein the third standby recovery procedure S3 and the fourth standby recovery procedure S4 each include the 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;
As shown in fig. 16, in the third standby recovery procedure S3, the third user operation is a standby recovery operation, that is, the third standby recovery procedure S3 includes a step 1018 of receiving the standby recovery operation, a step 1021 of displaying the first video image 201 on the main interface 20 according to the standby recovery operation.
As shown in fig. 17, the fourth standby recovery process S4 includes:
Step 1007, receiving a third user operation;
According to the third user operation, step 1021 is performed, step 1021 displaying the first video image 201 on the main interface 20;
the fourth standby recovery procedure S4 further includes performing step 1018 of receiving a standby recovery operation before receiving the third user operation.
As shown in fig. 16 and 17, before the process of displaying the first video image 201 by the main interface 20, the third standby recovery process S3 and the fourth standby recovery process S4 further include:
according to the standby restoration operation, step 10201 is performed of transmitting a standby restoration control instruction to the second electronic device over the wireless communication link, the standby restoration control instruction being for instructing the second electronic device to restore the wireless communication link to the continuous communication state.
After the wireless communication link is restored to the continuous communication state, the first electronic device 100 may receive the video image from the second electronic device 200 through the wireless communication link, and then may perform step 1021 according to the standby restoring operation, which includes displaying the first video image 201 on the main interface 20.
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 (e.g., a hover ball), and in addition, the third user operation may further include a first slide gesture operation on the preset position 30, as shown in fig. 16, after step 1017, when the first electronic device receives the click operation on the hover ball by the user or the first slide gesture operation on the preset position 30, that is, the process of steps 10201 to 1021 is performed to recover the display of the first video image 201.
For example, in the fourth standby recovery process S4, the standby recovery operation includes a touch operation applied to the preset position 30, and assuming that the preset position 30 is a region to be displayed corresponding to the first video image, as shown in fig. 17, after step 1017, when the first electronic device receives the touch operation applied to the preset position 30 by the user, step 10201 is performed to implement sending a standby recovery control instruction to the second electronic device, and when the first electronic device receives the first sliding gesture operation applied to the preset position 30 by the user, step 1021 is performed to recover the display of the first video image 201. When the user performs the first sliding gesture operation on the preset position 30, the user must touch the preset position 30 first, that is, when the user performs the third user operation, the process of sending the standby resume operation instruction is triggered in advance due to the front operation of the third user operation, and then the first video image 201 is displayed according to the third user operation.
In the embodiment shown in fig. 16 and 17, the data transmission process shown in fig. 18 may be applied to the wireless communication link, where the wireless communication link includes a plurality of synchronization periods, and the duration of the synchronization periods is, for example, 524ms, and each synchronization period includes an exploration window and a data transmission stage, and the duration of the exploration window is, for example, 16ms, and in each exploration window, the Master device Master involved in the wireless communication link may send a synchronization beacon Beacons, and the Slave device Slave involved in the wireless communication link only needs to receive the synchronization Beacons to achieve synchronization with the Master device, so that, in the embodiment of the present application, if the multi-station capturing system includes a mobile phone and a wireless capturing device, the mobile phone is used as the Master device, and the wireless capturing device is used as the Slave device, so that the power consumption of the wireless capturing device is reduced. As shown in fig. 15 and 18, in the continuous communication state, the data transmission stage in each synchronization cycle transmits data, and in the first periodic sleep communication state and the second periodic sleep communication state, the wireless communication link includes alternating sleep stages and wake-up stages, the data transmission stage of the wake-up stage can transmit data, and the data transmission stage of the sleep stage can not transmit data, wherein the duration of the sleep stage of the first periodic sleep communication state is smaller than the duration of the sleep stage of the second periodic sleep communication state.
In some embodiments, when the second electronic device enters the standby mode, the user may be reminded that the camera is still used in the standby mode of the multi-camera shooting system by controlling the auxiliary light on the second electronic device to flash, except that the lens and other components of the second electronic device are not used. It will be appreciated that other ways of reminding the user may be used, not just the auxiliary light flashing, and therefore the present embodiment is not limited to the way of reminding the user that the stand-by is operating in the standby mode. As shown in fig. 19, 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 photographing device, when the first electronic device 100 only displays a picture shot by the first electronic device 100, the second electronic device 200 and the third electronic device 300 are respectively provided with an auxiliary lamp 900, the first electronic device 100 sends a standby control instruction to the second electronic device 200 and the third electronic device 300, so that the screen and the camera of the second electronic device 200 are closed, the camera of the third electronic device 300 is closed, and the auxiliary lamps on the second electronic device 200 and the third electronic device 300 flash to prompt a user that the device is still used in a standby multi-machine position, but the camera of the device is not used.
In some embodiments, as shown in fig. 20, the first electronic device 100 receives a touch operation or a click operation performed by a user on the preset position 30, and sends a standby resume instruction to the second electronic device according to the touch operation, and after the standby resume control instruction is sent to the second electronic device, the method further includes:
The first electronic device 100 displays the transition image 209 at the preset position 30 according to a third user operation, for example, a first slide gesture operation acting on the preset position 30;
The process of displaying the first video image on the main interface by the first electronic device 100 according to the third user operation includes that when the first electronic device receives the first video image from the second electronic device through the wireless communication link restored to the continuous communication state by the first electronic device 100 according to the third user operation, the transition image 209 is replaced by the first video image 201, that is, the restored first video image 201 is displayed on the first electronic device 100, and the restored first video image 201 is from the second electronic device.
For example, on the basis of the one shown in fig. 11 or fig. 16, the third user operation is a standby recovery operation. I.e. the restoration of the wireless communication link, the restoration of the already closed components of the second electronic device and the restoration of the first video image 201 displayed by the first electronic device may be instructed by the same user operation. After sending the standby recovery control instruction to the second electronic device, the method further includes:
The first electronic device 100 displays a transition image at a preset position according to the standby restoration operation;
The first electronic device 100 replaces the transition image 209 with the first video image 201 when the first electronic device receives the first video image from the second electronic device through the wireless communication link restored to the continuous communication state according to the standby restoration operation. That is, the step of displaying the transition image is added on the basis of that shown in fig. 11 or fig. 16, and step 1021 is replaced with a "process of replacing the transition image 209 with the first video image 201".
For example, the third user operation, i.e., the standby restoring operation, is the first swipe gesture operation acting on the preset position 30. After the first electronic device 100 conceals the first video image 201 and sends the standby control instruction to the second electronic device, when the user wishes to resume displaying the first video image 201, the first sliding gesture operation acting on the preset position 30 may be performed on the first electronic device 100, and since the video image of the auxiliary machine position needs to be displayed, the auxiliary machine position needs to transmit the video image to the first electronic device 100, and a time difference between the first sliding gesture operation and displaying the video image of the auxiliary machine position on the main interface may occur. In the time difference, the first electronic device 100 displays a pre-stored transition image 209 at the preset position 30 according to the first sliding gesture operation, and when the second electronic device and the wireless communication link recover from the low-power consumption state, the first electronic device 100 replaces the transition image 209 with the first video image 201 to realize that the first video image 201 is recovered to be displayed at the first electronic device 100, thereby solving the problem of image display delay. The transition image may be a dynamic effect of the blurring rotation, or may be another type of fixed image, and the type of the transition image is not limited in this embodiment.
Similarly, for example, on the basis of the operation shown in fig. 13 or 17, 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 may be triggered by a touch operation at a preset location 30 on the first electronic device. After sending the standby recovery control instruction to the second electronic device, the method further includes:
the first electronic device 100 displays a transition image at a preset position according to a third user operation;
The first electronic device 100 replaces the transition image 209 with the first video image 201 when the first electronic device receives the first video image from the second electronic device through the wireless communication link restored to the continuous communication state according to the standby restoration operation. That is, on the basis of the one shown in fig. 13 or 17, a step of displaying the transition image is added, and step 1021 is replaced with a "process of replacing the transition image 209 with the first video image 201".
Specifically, for example, the standby recovery operation is a touch operation or a click operation of the preset position 30 of the first electronic device 100, and the third operation is a first slide gesture operation for 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 wishes to resume the display of the first video image 201, clicking the preset position 30 of the first electronic device 100 and performing a first slide gesture operation, in which a standby resume operation and a third user operation are sequentially performed. When the standby recovery operation of clicking the preset position 30 by the user is received, a standby recovery control instruction is sent to the second electronic device to recover the standby state in advance, and after the first sliding gesture operation is received, the auxiliary machine position is required to transmit the video image to the first electronic device 100 because the video image of the auxiliary machine position is required to be displayed, and the time difference between the first sliding gesture operation and the video image of the auxiliary machine position displayed on the main interface can occur. In the time difference, the first electronic device 100 displays a pre-stored transition image 209 at the preset position 30 according to the first sliding gesture operation, and when the second electronic device and the wireless communication link recover from the low-power consumption state, the first electronic device 100 replaces the transition image 209 with the first video image 201 to realize that the first video image 201 is recovered to be displayed at the first electronic device 100, thereby solving the problem of image display delay.
In addition, different auxiliary locations may have different preset positions on the first electronic device, for example, the second electronic device has a corresponding preset position on the upper left corner of the screen on the first electronic device, and the third electronic device has a corresponding preset position on the upper right corner of the screen on the first electronic device. Assuming that the first electronic device currently displays only the second video image 202 and no other video images are displayed, the second video image 202 is a video image captured by the first electronic device itself, and both the second electronic device and the third electronic device may be in standby mode.
For example, in the first scenario, when the user clicks on, for example, the upper left corner, or a screen-swipe operation from the upper left corner to the lower right corner, as the third user operation, the first electronic device may send a standby resume control instruction to the second electronic device.
For example, in the second scenario, when the user clicks on, for example, the upper right corner, or swipes the screen from the upper right corner to the lower left corner, the first electronic device may send a standby resume control instruction to the third electronic device. An embodiment of a process for implementing control over a wireless communication link between a first electronic device and a second electronic device is described below, in which, in an initial state, the first electronic device only displays a second video image 202, where the second video image 202 is a video image captured by the first electronic device itself, after which, the user controls the first electronic device through a touch event, and if a screen control of the second electronic device at a remote end is involved in the touch event, for example, the user controls to display the first video image from the second electronic device on the first electronic device, the control is forwarded to VirtualCameraAgent of the second electronic device through CAMERAHAL, so that the video image captured by the second electronic device is transmitted to the first electronic device to form the first video image displayed in the main interface.
The embodiments of the present application will be described below by way of two specific examples.
As shown in fig. 21, 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 concealment of the video image may be achieved by a slide-in and slide-out operation on the screen of the first electronic device 100 acting on the preset position 30. For example, the main interface of the first electronic device 100 may display the second video image 202 captured by the first electronic device 100, where the second video image 202 is used as a recording screen, a sliding-out operation on the right sliding screen of the preset position 30 may cause the first video image 201 captured by the second electronic device 200 to be displayed on the main interface of the first electronic device 100, a video switching operation may cause the first video image 201 and the second video image 202 in the main interface to be switched, so that the first video image 201 is switched to the recording screen, and a sliding-in operation on the left sliding screen of the preset position 30 may cause the second video image 202 to be hidden. In addition, picture-in-picture recording can also be realized. The second electronic device 200 may choose to enable the low power mode or may choose not to enable the low power mode if the first electronic device 100 is hiding the first video image 201 and the video image of the second electronic device 200 is not being used. For the control transmission of the second electronic device 200, the time delay of the control operation on the first electronic device 100 can be reduced by the above-mentioned priority optimization strategy.
As shown in fig. 22, a mobile phone supporting multi-camera shooting is used as a first electronic device 100 and a fourth electronic device 400 to be networked, and the fourth electronic device 400 is a shooting device. The specific process and principle may be similar to that described above in relation to fig. 21, except that the first video image 201 in fig. 22 is from the fourth electronic device 400, and the fourth electronic device 400 may be provided with a low power consumption indicator light and a start indicator light, where the low power consumption indicator light of the fourth electronic device 400 blinks when the first electronic device 100 does not use the video image of the fourth electronic device 400, indicating that the device has been networked, but does not use shooting or preview, and where the start indicator light of the fourth electronic device 400 blinks when the first video image 201 that is slid out is an image from the fourth electronic device 400, indicating that the device has been enabled for shooting or preview.
