The method of controlling a camera provided by the present application is described in detail below in conjunction with the system shown in fig. 1, and fig. 3 shows a schematic interactive flow chart of a method 300 of controlling a camera.
Step 301, when the second electronic device detects a first request from the first electronic device, starting a physical camera of the second electronic device and displaying a first User Interface (UI), wherein the first request requests the second electronic device for the use authority of the physical camera.
In step 302, when the second electronic device detects a second request from the first UI, a first operation is performed on the physical camera, the first operation being an operation requested by the second electronic device to be performed by the second request.
The first electronic device may, for example, discover the second electronic device by using a near-field broadcast manner, and then the first electronic device may establish a connection with the second electronic device and may acquire parameter information of a physical camera of the second electronic device, and the first electronic device may create a virtual camera corresponding to the physical camera of the second electronic device on the first electronic device according to the parameter information of the physical camera of the second electronic device, and then the first electronic device may achieve the purpose of controlling the physical camera of the second electronic device through the virtual camera, where the first electronic device is a master control device and the second electronic device is a remote device.
It should be noted that, in the embodiment of the present application, the parameter information of the physical camera is used to indicate the capability of the physical camera, for example, the parameter information of the physical camera may include the resolution, the frame rate, the color format and so on supported by the physical camera.
After the first electronic device creates a virtual camera corresponding to the physical camera of the second electronic device on the first electronic device, a user may call the virtual camera through an Application (APP) installed on the first electronic device, and when the virtual camera is called, the second electronic device may detect a first request from the first electronic device, where the first request is used to request the second electronic device to start up its physical camera, and the second electronic device starts up the physical camera according to the first request.
For example, the APP on the first electronic device may display a UI on its display interface, where the UI is used for the user to select a remote device that requests the usage right of the physical camera, and may be further used for the user to further select the usage right of the front camera or the rear camera of the physical camera. In order to distinguish from a UI that appears subsequently, the UI may be referred to as a UI corresponding to the remote device in view of the UI being used for the user to select the remote device.
Assuming that the user selects a front-facing camera of the physical camera of the second electronic device, after the user finishes selecting, the APP on the first electronic device calls a virtual camera corresponding to the physical camera of the second electronic device, and after the virtual camera is called, the second electronic device detects a first request from the second electronic device, the first request is used for requesting the second electronic device to start the front-facing camera of the right camera of the second electronic device, and the second electronic device calls a camera interface to start the front-facing camera according to the first request. The physical camera of the second electronic device captures a current picture in an actual environment, and the second electronic device can send the data information of the current picture and the parameter information of the physical camera when the current picture is shot to the first electronic device, so that the first electronic device displays the current picture corresponding to the data information of the current picture to a user according to the parameter information of the physical camera when the current picture is shot.
It is worth mentioning that, when the virtual camera corresponding to the physical camera of the second electronic device is invoked, the first electronic device may display the UI corresponding to the virtual camera based on the invocation, and the UI corresponding to the virtual camera may be used for the user to control the physical camera of the second electronic device.
Further, the second electronic device may generate a UI (e.g., a first UI) based on the first request from the first electronic device and display the first UI on the second electronic device. The user may enable control of the physical camera of the second electronic device on the second electronic device through interaction with the first UI. When the user completes a certain operation on the first UI, the second electronic device detects a second request from the first UI, and the second electronic device performs the first operation on the physical camera according to the second request.
For example, the user requests to increase the resolution of the physical camera from the second electronic device through the first UI, at which time the second electronic device performs a first operation to increase the resolution of the physical camera in response to the user's request.
Illustratively, the first UI may display a screen captured by the physical camera of the second electronic device in real time to the user in addition to providing an interaction portal between the user and the second electronic device, in which case the method 300 may further include:
in step 303, the second electronic device displays a first screen on the first UI, where the first screen is a current screen acquired by the physical camera after the first operation is performed.
For example, the second electronic device may further transmit data information of the first screen and parameter information of a physical camera of the second electronic device when the first screen is photographed to the first electronic device, in which case the method 300 may further include:
in step 304, the second electronic device sends the data information and the first parameter information of the first frame to the first electronic device, where the first parameter information is the parameter information of the physical camera when the first frame is shot.
For example, when the second electronic device performs the first operation, the resolution of the physical camera is increased from 1280×720 to 1920×1080, in which case the resolution used when the physical camera shoots the first picture is 1920×1080, and after the first picture is acquired, the second electronic device transmits the data information of the first picture and the parameter information of the physical camera when shooting the first picture to the first electronic device, so that the first electronic device displays the first picture corresponding to the data information of the first picture to the user according to the parameter information of the physical camera when shooting the first picture, where the parameter information of the physical camera when shooting the first picture includes the resolution, the resolution is 1920×1080, in other words, the resolution of the first picture displayed to the user by the first electronic device is 1920×1080, which is the resolution used when the physical camera shoots the first picture.
Illustratively, the second electronic device may process the request from the first electronic device in addition to the request from the first UI, in which case the method 300 may further include:
In step 305, when the second electronic device detects a third request from the first electronic device, a second operation is performed on the physical camera, where the second operation is an operation performed by the second electronic device requested by the third request.
Step 306, the second electronic device sends the data information and the second parameter information of the second frame to the first electronic device, where the second frame is the current frame obtained by the physical camera after the second operation is performed, and the second parameter information is the parameter information of the physical camera when the second frame is shot.
When a user performs a certain operation on the virtual camera corresponding to the physical camera of the second electronic device on the UI corresponding to the virtual camera, the second electronic device may detect a third request from the first electronic device, and the second electronic device executes the second operation according to the third request, and then the second electronic device may send, after executing the second operation, data information of the second picture acquired by the physical camera and parameter information of the physical camera when the second picture is shot to the first electronic device, so that the first electronic device displays the second picture corresponding to the data information of the second picture to the user according to the parameter information of the physical camera when the second picture is shot.
For example, for a detected request from the UI corresponding to the virtual camera, or a request from the first UI, the second electronic device may first determine whether the control policy is satisfied, and when the control policy is satisfied, the second electronic device executes the corresponding request.
The control strategy may include: a sequence priority control strategy, a local priority control strategy and an opposite terminal priority strategy, wherein the sequence priority control strategy refers to that the second electronic equipment sequentially executes corresponding requests according to the sequence of receiving the requests; the local priority control policy refers to that when an operation requested to be executed by a request from a first electronic device collides with an operation requested to be executed by a request from a second electronic device, the second electronic device refuses to execute the request from the first electronic device; the peer-to-peer priority policy refers to that when an operation requested to be performed by a request from a first electronic device collides with an operation requested to be performed by a request from a second electronic device, the second electronic device refuses to perform the request from the second electronic device.
For example, assume that the control policy is a sequential priority control policy, in which case the second electronic device executes all requests detected, in which case the second electronic device executes both for the second request and for the third request.
In this case, when the second electronic device detects both the second request and the third request, it is assumed that the first operation requested by the second request and the second operation requested by the third request to be performed by the second electronic device collide, and the second electronic device refuses to perform the second operation corresponding to the third request based on the local priority control policy.
For example, the second electronic device detects both the second request, which corresponds to the first operation of setting the flash of the physical camera to the auto mode, and the third request, which corresponds to the second operation of setting the flash of the physical camera to the normally on mode, in which case the second electronic device may refuse to execute the third request, in other words, in which case the second electronic device executes only the second request, i.e., sets the flash of the physical camera to the auto mode.
In this case, when the second electronic device detects both the second request and the third request, it is assumed that the first operation requested by the second request and the second operation requested by the third request to be performed by the second electronic device collide, and at this time, the second electronic device refuses to perform the first operation corresponding to the second request based on the peer-to-peer priority control policy.
For example, the second electronic device detects both the second request, which corresponds to the first operation of turning on the night view photographing mode, and the third request, which corresponds to the second operation of turning on the large aperture photographing mode, in which case the second electronic device may refuse to execute the second request, in other words, in which case the second electronic device executes only the third request, that is, the large aperture photographing mode.
Illustratively, the control policy may be preconfigured on the second electronic device, or the control policy may be set by the user through the first UI, for example, the user interacts with the second electronic device through the first UI, and the control policy is set on the first UI, where the second electronic device may detect user input data from the first UI, and the second electronic device obtains the control policy according to the user input data.
In the embodiment of the present application, the user operating the first electronic device and the user operating the second electronic device may be the same user, or may be different users, which is not limited in the embodiment of the present application.
The method 300 is described in detail below with reference to fig. 4-5, taking a live scenario as an example.
When the first electronic device finds the second electronic device by using the near field mode, the first electronic device can create a virtual camera corresponding to the physical camera of the second electronic device on the first electronic device, and then the first electronic device can control the physical camera of the second electronic device through the virtual camera, and the first electronic device is a master control device and the second electronic device is a remote device. For the manner in which the first electronic device discovers the second electronic device and the manner in which the first electronic device creates the virtual camera, please refer to the related description in the method 300, and for brevity, the description is omitted here.
The method comprises the steps that a first APP installed on a first electronic device is used for live broadcasting by an anchor, wherein the first APP has a live broadcasting function and has the capability of calling a virtual camera corresponding to a physical camera of a second electronic device.
The method comprises the steps that when a live broadcast is performed, a host uses the function of a physical camera of a first electronic device and the function of a virtual camera corresponding to a physical camera of a second electronic device, for the physical camera of the first electronic device, when a user opens the live broadcast function, the first electronic device correspondingly opens the physical camera, the physical camera is assumed to be currently opened to be a front-end camera, at the moment, the user watching the live broadcast can see the host on the electronic device, for the virtual camera corresponding to the physical camera of the second electronic device, the host can select on a UI corresponding to a remote device displayed by a first APP, and for the virtual camera corresponding to the physical camera of the second electronic device, the host selects a rear-end camera corresponding to the virtual camera corresponding to the second electronic device, and after the host completes selection, the first APP can call the virtual camera corresponding to the physical camera of the second electronic device on the first electronic device.
When the virtual camera corresponding to the second electronic device is called, the virtual camera proxy module on the second electronic device detects a first request from the first APP, and the first request is used for requesting the second electronic device to start the rear camera of the physical camera of the second electronic device because the host selects the rear camera of the virtual camera corresponding to the second electronic device, and the virtual camera proxy module calls the camera interface to start the rear camera of the physical camera according to the first request.
The virtual camera agent module calls the camera interface to start the rear camera of the physical camera according to the first request, the physical camera captures a current picture in an actual environment, the virtual camera agent module can call the camera interface to send data information of the current picture and parameter information of the physical camera when the current picture is shot to a first APP on the first electronic device, and the first APP can display the current picture corresponding to the data information of the current picture to a user watching live broadcasting according to the parameter information of the physical camera when the current picture is shot. At this time, the first electronic device may display the photographing picture of the physical camera of the first electronic device and the photographing picture of the virtual camera corresponding to the physical camera of the second electronic device, and similarly, for a user watching live broadcast, not only can see the photographing picture of the physical camera of the first electronic device but also can see the photographing picture of the virtual camera corresponding to the physical camera of the second electronic device on the electronic device.
For example, when a host is live, a user of the first electronic device is a host, a user of the second electronic device is an assistant of the host, when the host starts live, a front camera of a physical camera of the first electronic device is used for shooting himself, when the host needs to show goods to a user watching live, a rear camera of a virtual camera corresponding to the second electronic device can be called on the first electronic device through the first APP, when the rear camera on the second electronic device is turned on, the assistant can shoot the goods to be shown, and at the moment, the user watching live can see not only the host but also the corresponding goods on the electronic device.
In addition, the assistant may also control the physical camera of the second electronic device on the second electronic device, for example, the virtual camera proxy module may generate a UI (e.g., a first UI) after detecting the first request from the first electronic device, and display the first UI401 on the second electronic device, the first UI401 may control the physical camera of the second electronic device through the first UI401, for example, the assistant may set a flash mode of the physical camera of the second electronic device through an option 4011, the assistant may set a tone mode of the physical camera through an option 4012, the assistant may adjust a resolution head of the physical camera through an option 4013, and the assistant may set other options of the physical camera through an option 4014.
It should be noted that the options shown in the first UI401 are only illustrated as examples, and in specific implementations, the first UI may further include more options than illustrated, for example, may further include a focusing option, which is not limited by the embodiment of the present application.
For example, the assistant adjusts the resolution of the physical camera via option 4013, at which point the virtual camera proxy module detects a request to adjust resolution (e.g., a second request) from the first UI, and the virtual camera proxy module invokes the camera interface to adjust the resolution of the physical camera based on the second request.
After executing the first operation corresponding to the second request, the virtual camera proxy module may call the camera interface to display, through the first UI, a current screen (for example, a first screen) acquired by the physical camera, in which case, as shown in fig. 4 (b), the first UI402 may be a first screen acquired by the physical camera by a person in a dashed line box 4025 in the first UI402, and the screen in a dashed line box 4025 shown in fig. 4 (b) may be a non-full screen display mode, and the assistant may set, through the option 4026, the screen in the dashed line box 4026 to a full screen display mode.
In addition, the virtual camera agent module can call the camera interface, data information of a first picture acquired by the physical camera after the first operation is executed and parameter information of the physical camera when the first picture is shot are sent to the first APP on the first electronic device, and the first APP displays the first picture corresponding to the data information of the first picture to a user watching live broadcast according to the parameter information of the physical camera when the first picture is shot.
For example, the assistant increases the resolution of the physical camera from 1280×720 to 1920×1080 through the option 4023, in which case the resolution used when the physical camera captures the first picture is 1920×1080, after the first picture is acquired, the second electronic device transmits the data information of the first picture and the parameter information of the physical camera when the first picture is captured to the first APP on the first electronic device, the first APP displays the first picture corresponding to the data information of the first picture to the user on the first electronic device according to the parameter information of the physical camera when the first picture is captured, the parameter information of the physical camera when the first picture is captured includes the resolution, the resolution is 1920×1080, in other words, the resolution of the first picture displayed to the user by the first electronic device is 1920×1080.
When the anchor performs a certain operation on the virtual camera corresponding to the physical camera of the second electronic device on the UI corresponding to the virtual camera, the virtual camera proxy module detects a third request from the first electronic device, and the virtual camera proxy module invokes the camera interface to perform a second operation according to the third request, and then the virtual camera proxy module may invoke the camera interface to send data information of a current picture (for example, a second picture) acquired by the physical camera after performing the second operation and parameter information of the physical camera when shooting the second picture to the first APP on the first electronic device, so that the first APP displays the second picture corresponding to the data information of the second picture acquired by the physical camera to a user watching live broadcast after performing the second operation according to the parameter information of the physical camera when shooting the second picture.
For example, the anchor selects a soft option corresponding to the tone on the UI corresponding to the virtual camera, at this time, the virtual camera proxy module detects a third request for requesting to adjust the tone of the physical camera to a soft mode, and the virtual camera proxy module invokes the camera interface to adjust the physical camera to the soft mode according to the third request, and then, the virtual camera proxy module may invoke the camera interface to send the data information of the second picture acquired by the physical camera after the mode adjustment and the parameter information of the physical camera when the second picture is shot to the first APP on the first electronic device, so that the first APP displays the second picture corresponding to the data information of the second picture on the first electronic device according to the parameter information of the physical camera when the second picture is shot to a user who views live broadcast.
As can be seen from the foregoing description, the virtual camera proxy module may detect a request from a UI corresponding to the virtual camera, and detect a request from the first UI, and in a specific implementation, the virtual camera proxy module may first send the request to the control policy management module, where the control policy management module stores a control policy, and the control policy management module determines whether the request can be executed on the premise of ensuring that the control policy is satisfied, and the control policy management module may notify the virtual camera proxy module of the result, and the virtual camera proxy module determines whether to execute the corresponding request according to the result. For a detailed description of the control strategy, please refer to the related description in the method 300, and for brevity, the description is omitted here.
For example, assuming that the control policy is a sequential priority control policy, the control policy management module obtains a result of allowing execution for all the detected requests, and notifies the virtual camera proxy module of the result, and the virtual camera proxy module calls the camera interface to execute the corresponding request, and in this case, the virtual camera proxy module calls the camera interface to execute the second request and the third request.
For example, it is assumed that the control policy is a local priority control policy, in this case, when the virtual camera proxy module detects both the second request and the third request, and it is assumed that the first operation requested to be performed by the second request conflicts with the second operation requested to be performed by the third request, the control policy management module refuses to perform the second operation corresponding to the third request based on the local priority control policy, and notifies the virtual camera proxy module of the result of refusal of the execution.
For example, the virtual camera proxy module detects both the second request, which corresponds to the first operation of setting the flash to the automatic mode, and the third request, which corresponds to the second operation of setting the flash to the constant mode, in which case the control policy management module refuses to execute the third request based on the local priority control policy, in other words, in which case the virtual camera proxy module invokes the camera to execute only the second request, setting the flash to the automatic mode.
For example, it is assumed that the control policy is a peer-to-peer priority control policy, in this case, when the virtual camera proxy module detects both the second request and the third request, and it is assumed that the first operation requested to be performed by the second request conflicts with the second operation requested to be performed by the third request, the control policy management module refuses to perform the first operation corresponding to the second request based on the peer-to-peer priority control policy, and notifies the virtual camera proxy module of the result of refusal of the execution.
For example, the virtual camera agent module detects both the second request and the third request, the first operation corresponding to the second request is to start the night scene photographing mode, the second operation corresponding to the third request is to start the large aperture photographing mode, in which case the control policy management module refuses to execute the second request based on the peer-to-peer priority control policy, in other words, in which case the virtual camera agent module invokes the camera to execute only the third request, i.e. to start the large aperture photographing mode.
For example, the control policy may be configured in advance in the control policy management module, or the control policy may be set by the user through the first UI, for example, the assistant may select an option on the first UI, the option representing a certain control policy, and after the assistant makes the selection, the inside of the second electronic device may acquire the control policy according to the selection of the assistant (e.g., user input data), and finally the acquired control policy may be saved in the control policy management module, so that the control policy management module may determine whether to allow the request to be executed according to the saved control policy.
For example, when the assistant sets a control policy through the first UI 402, the assistant may select a setting option in the first UI 402, in response to an operation of the assistant, the second electronic device may display the first UI 501 as shown in fig. 5 (a), the first UI 501 may include a control policy option 5011 therein, the assistant may select the control policy option 5011 in the first UI 501, in response to an operation of the assistant, the second electronic device may display the first UI 502 as shown in fig. 5 (b), the first UI 502 may include a sequential priority control policy option 5021 therein, a local priority control policy option 5022, and an opposite priority control policy option 5023, and the first assistant may select one of the first UIs 502 as a control policy, for example, the assistant selects the sequential priority control policy option 5021 on behalf of the assistant.
It should be noted that, in the embodiment of the present application, the first UI may be suspended on any interface and may be dragged at will, for example, the first UI may be suspended on a screen locking interface of the second electronic device or other interfaces after the second electronic device is unlocked.
It should be noted that, the foregoing description only uses the assistant to set the control policy as an example, but this is not a limitation on the embodiment of the present application, and when the embodiment is implemented, the anchor or other users may complete the setting of the control policy.
It should be further noted that, in the embodiment of the present application, the time when the control policy is set by the user is not limited, and the user may set the control policy through the first UI at any time after the display of the first UI, and the control policy management module stores the control policy or updates the stored control policy in real time according to the setting of the user.
