The first terminal 102 receives the video pictures collected by the at least one camera of the second terminal 106, and displays at least a part of the video pictures collected by the at least one camera of the second terminal 106 in real time in the interaction area. Therefore, the first terminal can simultaneously display the pictures shot by different cameras under the condition that the user does not need to repeatedly switch the cameras, the operation of repeatedly switching the cameras is omitted, and the video call interaction effect of the user is improved.

In one embodiment, the first terminal is a terminal used by a first user and the second terminal is a terminal used by a second user. The first terminal 102 may send an image formed by at least a part of a first video image acquired by the first camera in real time and at least a part of a second video image acquired by the second camera in real time, which are displayed in the interaction area, to the second terminal 106, and the second terminal 106 may display the image in the interaction area after receiving the image. Therefore, the first user using the first terminal can display the video pictures acquired by the two cameras to the second user at the same time without repeatedly switching the pictures shot by the cameras, and the interaction effect of video call is improved.

In one embodiment, a social application is running on the first terminal 102, a social application is also running on the second terminal 106, and a video call between the first terminal 102 and the second terminal 106 can be established through the social application. The Social application may be an instant messaging application, an SNS (Social Network Service) application, or a live application, among others. The second terminal is a terminal used by a call object currently performing a video call with the first terminal, and the number of the second terminals may be one or more, for example, in a scene of a multi-person video call, there may be a plurality of call objects performing a video call with the first terminal at the same time. The video call between the first terminal and the second terminal may be initiated by the first terminal or initiated by the second terminal. Video calls are a communication mode based on networks that transmit voice and pictures between terminals in real time.

In one embodiment, as shown in fig. 2, a video call interaction method is provided, which is described by taking the method as an example applied to the first terminal 102 in fig. 1, and includes the following steps:

step 202, responding to a triggering operation of a video call between a first terminal and a second terminal, and displaying an interaction area of the video call, wherein the first terminal is provided with a first camera and a second camera which work simultaneously when the video call is carried out, and the first camera and the second camera have different visual fields.

When the first user needs to have a video call with the second user, the video call can be established with the second terminal through the first terminal. In this embodiment, the first terminal is provided with at least two cameras, and to distinguish the two cameras, the two cameras are respectively referred to as a first camera and a second camera, it should be noted that terms "first" and "second" in the description, claims and drawings of the present application are used to distinguish different objects, rather than to refer to a certain object specifically, for example, the first camera may be any one of the cameras provided on the first terminal and having a shooting function, and for example, the first video picture may be a video picture shot by any one of the cameras provided on the first terminal and having a shooting function.

In the embodiment of the present application, the first camera and the second camera are two cameras with different shooting views, which are disposed on the first terminal. For example, the first camera may be a front camera and the second camera is a rear camera, or the first camera is a rear camera and the second camera is a front camera. For another example, the first camera and the second camera may be cameras respectively disposed at the left and right sides of the first terminal, or may be cameras respectively disposed at the upper and lower sides of the first terminal.

The triggering operation of the video call may be a triggering operation of initiating the video call, or a triggering operation of receiving the video call. For example, the first terminal may initiate a video call to the second terminal, and after the video call is initiated, the interactive area of the video call is displayed, and the first terminal may also display the interactive area of the video call after the second terminal receives the video call. For another example, the second terminal may initiate a video call to the first terminal, and after the first terminal receives the message of the video call, the interactive area of the video call is automatically displayed, and the first terminal may further display the interactive area of the video call after receiving the video call. The triggering operation of the video call can be a single-click operation, a double-click operation or a sliding operation triggered in the video interaction area.

The interactive area is an area in the display interface for the user to interact with the video call. In some embodiments, only the interaction zone may be displayed on the screen of the first terminal, i.e. the interaction zone fills up the screen of the first terminal. Fig. 3 is a schematic diagram of an interaction area of a video call in one embodiment. Optionally, the interaction area may include at least one icon for turning on a camera, may further include at least one icon for turning off a camera, may further include at least one of an icon for ending a video call and an icon for inviting more users to participate in the video call, and may further include attribute information of the users participating in the video call, for example, may be a user avatar or a user nickname, and the like. The interactive zone may also include attribute information related to the video call, such as information on the length of time the video call was established. The interactive area may further include an icon to turn on or off the mute, and may further include an icon to turn on or off the handsfree function. In some embodiments, the interactive area may also be a small window suspended on other interfaces displayed on the first terminal, for example, the interactive area may be reduced to a small window suspended in the instant messaging session interface, as shown in fig. 4.

Specifically, in implementing the step 202, the first terminal may display the interactive area of the video call when detecting a trigger operation of initiating the video call, and may also display the interactive area of the video call when detecting a trigger operation of accepting a video call initiated by another person.

In one embodiment, the video call interaction method is applicable to instant messaging applications. Specifically, the first terminal can display a session page for performing an instant session with the session object through the instant messaging application, and enter a video call interaction interface for performing video call interaction between the first terminal and a second terminal corresponding to the session object from the session page in response to a triggering operation of a video call between the session page and the session object.

The session page may be a session page of a single chat session, that is, a session page of an instant session with one session object. The session page may also be a session page of a group session, i.e. a session page of an instant session with at least one group member of the group session.

Specifically, after the session page is displayed, the first terminal may enter the video call interaction interface from the session page according to the triggering operation of the video call between the first user and the session object in the session page. In the video call interaction interface, a first user may perform video call interaction with a session object using a second terminal through a first terminal, for example, the first user may display, to the session object, video pictures acquired by a first camera and a second camera simultaneously through a trigger operation, and may also view video pictures acquired by at least one camera of the second terminal.

And 204, in the interaction area, displaying at least one part of a first video picture acquired by the first camera in real time, displaying at least one part of a second video picture acquired by the second camera in real time, and displaying at least one part of a video picture acquired by at least one camera of the second terminal in real time.

Specifically, during a video call, the first terminal may display at least a portion of the first video picture and at least a portion of the second video picture, and simultaneously display at least a portion of the video picture captured by the camera of the second terminal. For example, the first terminal may display the entire content of the first video picture, the entire content of the second video picture, and the entire content of the video picture captured by the camera of the second terminal in real time in the interactive area. The first terminal can also display a fusion picture of the first video picture and the second video picture in the interaction area, and can also display the fusion picture formed by fusing the first video picture, the second video picture and the video picture acquired by the second terminal in real time in the interaction area. The detailed description of step 204 will be described in detail later.

In one embodiment, in order to enable the first terminal to display a video picture acquired by a camera of the second terminal, the second terminal may directly transmit the video picture acquired by at least one camera to the first terminal, and after receiving the video picture, the first terminal displays at least a part of the video picture in the interaction area. In other embodiments, the second terminal may further send a processed picture obtained by processing a video picture acquired by at least one camera to the first terminal, and the first terminal displays at least a part of the video picture in the interactive region according to the processed picture, for example, the processed picture may be a fusion picture obtained by fusing video pictures acquired by two cameras of the second terminal.

In one embodiment, the first terminal may default to automatically turn on the first camera and the second camera after the video call is successfully established, where the first camera acquires the first video picture in real time, the second camera acquires the second video picture in real time, and displays at least a portion of the first video picture and at least a portion of the second video picture in the interaction area.

In an embodiment, the first terminal may further automatically turn on the first camera by default after the video call is established, and according to an operation of turning on the second camera triggered by the first user in the interaction area, the first camera and the second camera work simultaneously, that is, both the first camera and the second camera are in an on state, the first camera acquires the first video picture in real time, the second camera acquires the second video picture in real time, and displays at least a part of the first video picture and at least a part of the second video picture in the interaction area.

According to the video call interaction method, when a first terminal and a second terminal carry out video call, a first camera and a second camera on the first terminal can be started simultaneously, the first camera collects a first video picture in real time, and the second camera collects a second video picture in real time, so that at least one part of the first video picture and at least one part of the second video picture which are collected by the first camera and the second camera respectively in real time and have different visual fields can be displayed in the interaction area of the video call.

In one embodiment, the step 204 of displaying at least a part of a first video picture acquired by a first camera in real time, displaying at least a part of a second video picture acquired by a second camera in real time, and displaying at least a part of a video picture acquired by at least one camera of a second terminal in real time in the interactive area includes: and displaying a first video picture acquired by the first camera in real time in a main picture area of the interactive area, displaying a second video picture acquired by the second camera in real time in a secondary picture area of the interactive area, and displaying a video picture acquired by at least one camera in real time in the interactive area, wherein the size of the main picture area is larger than that of the secondary picture area.

In this case, the main screen area is an area having a larger area than the sub screen area, and therefore, the content displayed in the main screen area is more easily seen by the user than the content displayed in the sub screen area. The main picture area and the secondary picture area divide the whole interactive area into two parts, so that the video pictures acquired by the two cameras in real time can be displayed separately.

Optionally, the position distribution and size of the main picture area and the sub picture area are both fixedly set. For example, the main picture area occupies two thirds of the screen size, and the sub-picture area occupies one third of the screen size, and for example, the main picture area is disposed above the screen and the sub-picture area is disposed below the screen. Alternatively, the position of the main screen area may be fixedly set, and the position of the sub-screen area may be moved, for example, the sub-screen area may be displayed superimposed on the main screen area, and the position of the sub-screen area may be moved to an arbitrary position above the main screen area along with a sliding operation by the user. Optionally, the position distribution and size of the main picture area and the sub-picture area may be adjusted according to user personalized operation, and the ratio of the occupied screen of the main picture area and the sub-picture area may be dynamically adjusted according to a real-time acquisition state of the camera in the call process. It can be understood that when the main picture area is used for displaying the portrait acquired by the rear camera, or when the sub-picture area is used for displaying the portrait acquired by the front camera, or when the sub-picture area is used for displaying the portrait acquired by the rear camera, the proportion of the picture area occupying the screen can also be adjusted in this way.

Specifically, the first terminal may display, in the main picture area, a video picture acquired by the rear camera of the first terminal in real time, and display, in the sub-picture area, a video picture acquired by the front camera of the first terminal in real time. Or the first terminal can display the video pictures acquired by the front camera of the first terminal in real time in the main picture area and display the video pictures acquired by the rear camera of the first terminal in real time in the secondary picture area.

In addition, the first terminal also displays a video picture acquired by at least one camera of the second terminal in real time in the interaction area, and displays a mode of the video picture acquired by the camera of the second terminal in the interaction area.

In some embodiments, the first terminal may display a video picture captured in real time by a camera of the second terminal in the main picture area. Specifically, as shown in part (c) of fig. 5, displaying a video picture captured by at least one camera of the second terminal in real time in the interaction area includes: and displaying the video pictures acquired by at least one camera of the second terminal in real time in the main picture area of the interactive area.

In some embodiments, the first terminal may display a video picture captured in real time by a camera of the second terminal in the secondary picture area. Specifically, as shown in part (a) or part (b) of fig. 5, displaying a video picture captured by at least one camera of the second terminal in real time in an interaction area includes: and displaying the video pictures acquired by at least one camera of the second terminal in real time in a secondary picture area of the interactive area.

Fig. 5 is a schematic interface diagram of an interaction area of a video call in one embodiment. Referring to fig. 5, in the interface diagram, an interactive area is divided into a main screen area 502 and a sub screen area 504. Referring to part (a) of fig. 5, the first terminal displays a video picture captured by a rear camera in a main picture area 502, displays a video picture captured by a front camera in a sub picture area 504, and simultaneously displays a video picture captured by a camera of the second terminal in the sub picture area 504. Referring to part (b) of fig. 5, the first terminal displays a video picture captured by a front camera in a main picture area 502, displays a video picture captured by a rear camera in a sub-picture area 504, and simultaneously displays a video picture captured by a camera of the second terminal in the sub-picture area 504. Referring to part (c) of fig. 5, the first terminal displays a video picture captured by the rear camera in the main picture area 502, displays a video picture captured by the front camera in the sub picture area 504, and simultaneously displays a video picture captured by the camera of the second terminal in the main picture area 502. In fig. 5, the portions (a), (b), and (c) are different embodiments.

In the embodiment, the video pictures acquired by the two cameras of the first terminal are separately displayed through the main picture area and the secondary picture area which are different in size, so that a first user can simultaneously view the video pictures acquired by the two cameras in different visual fields in the video call process without repeatedly switching.

In some embodiments, the first user may change the area in which the first video frame and the second video frame are displayed. Specifically, the method may further include: and responding to the switching operation of the primary and secondary pictures triggered in the interactive area, displaying a second video picture acquired by the second camera in real time in the primary picture area of the interactive area, and displaying a first video picture acquired by the first camera in real time in the secondary picture area of the interactive area.

The main and sub-picture switching operation is an operation for switching a video picture displayed in the main picture area and the sub-picture area.

Fig. 6 is a schematic interface diagram of an interaction area of a video call in one embodiment. Referring to fig. 6, in the interface diagram, an interactive area is divided into a main screen area 602 and a sub screen area 604. The first terminal displays the video pictures collected by the rear camera in the main picture area 602, displays the video pictures collected by the front camera in the secondary picture area 604, and simultaneously displays the video pictures collected by the camera of the second terminal in the secondary picture area 604. The first terminal may display a video picture captured by a front camera in the main picture area 602, a video picture captured by a rear camera in the secondary picture area 604, and simultaneously display a video picture captured by a camera of the second terminal in the secondary picture area 604, in response to a main-secondary picture switching operation 606 triggered by the first user.

In the above embodiment, different video pictures acquired by the two cameras of the first terminal can be displayed in a large picture or a small picture according to the needs or preferences of the user, so that the preferences of different users can be met, and the video call interaction effect is improved.

In some embodiments, the second terminal is provided with a third camera and a fourth camera which work simultaneously when the video call is carried out; the third camera and the fourth camera have different visual fields; displaying at least one part of a video picture acquired by at least one camera of the second terminal in real time in an interaction area, wherein the method comprises the following steps: and displaying a third video picture acquired by the third camera in real time in a main picture area of the interactive area, and displaying a fourth video picture acquired by the fourth camera in real time in a secondary picture area of the interactive area.

In this embodiment, the second terminal can open two cameras when carrying out the video conversation, and the second user just can look over the video picture that two cameras were gathered, can also convey the video picture that two cameras gathered separately to first terminal simultaneously. The second terminal is provided with a third camera and a fourth camera, and the third camera and the fourth camera are two different cameras with different shooting visual fields arranged on the second terminal. For example, the third camera is a front camera and the fourth camera is a rear camera, or the third camera is a rear camera and the fourth camera is a front camera. For example, the third camera and the fourth camera may be cameras respectively disposed on the left and right sides of the second terminal, or may be cameras respectively disposed on the upper and lower sides of the second terminal.

The second terminal can start the third camera and the fourth camera according to the triggering operation of the video call between the first terminals, and sends the video pictures acquired by the third camera and the video pictures acquired by the fourth camera in real time to the first terminal, and the first terminal can display the third video pictures acquired by the third camera in real time and the fourth video pictures acquired by the fourth camera in real time in the main picture area of the interaction area and the secondary picture area of the interaction area while displaying the video pictures acquired by the first camera in real time in the interaction area. For example, the first terminal displays a video picture acquired by a rear camera of the second terminal in real time in a main picture area, and displays a video picture acquired by a front camera of the second terminal in real time in a secondary picture area. For another example, the first terminal displays a video picture acquired by a front camera of the second terminal in real time in the main picture area, and displays a video picture acquired by a rear camera of the second terminal in real time in the secondary picture area. The video pictures collected by different cameras displayed in the main picture area can be displayed in a vertical split screen mode or in a left-right split screen mode. The video pictures collected by different cameras displayed in the secondary picture area can be displayed in a vertical split screen mode or in a left-right split screen mode. In one embodiment, when the main screen area displays the video pictures acquired by different cameras in a split-screen manner, the position distribution and the size of the different video pictures in the main screen area may be fixedly set. For example, when the first terminal displays the front video picture collected by the front camera and the rear video picture collected by the rear camera in a split screen manner, the front video picture and the rear video picture respectively occupy half of the main picture area. For another example, the front video frame occupies two thirds of the main screen area, and the rear video frame occupies one third of the main screen area. For another example, the front video screen is displayed in the upper half of the main screen area and the rear video screen is displayed in the lower half of the main screen area, or vice versa, the front video screen is displayed in the lower half of the main screen area and the rear video screen is displayed in the upper half of the main screen area.

Specifically, the first terminal may obtain a trigger operation of a user for a screen splitting line in the main picture area, and adjust a ratio occupied by different video pictures according to the trigger operation. For example, when the user slides the split screen line up and down, the proportion occupied by the front video picture and the rear video picture in the main picture area is dynamically adjusted in real time, so that the personalized requirements of the user can be met, the user can be helped to adjust the video pictures in real time in the video call process, and the call video pictures are clearer.

In an embodiment, when the main screen area displays the video pictures acquired by different cameras in a split-screen manner, the position distribution and the size of the different video pictures in the main screen area may be dynamically adjusted by the first terminal in real time according to the real-time video acquisition state. Specifically, the closer the distance to the acquired target is, the larger the target in the acquired video picture is, and then, under the condition that the display area is smaller, a target may be locally missing and a complete video picture cannot be presented, and the first terminal may dynamically adjust the ratio of the front video picture and the rear video picture occupied in the main picture area according to the distance from the target. For example, the first terminal may obtain a distance between the front camera and the portrait of the user in real time, and dynamically adjust a proportion of the front video picture in the main picture area according to the distance, where the larger the distance is, the smaller the collected portrait of the user is, the smaller the proportion of the front video picture in the main picture area is, the smaller the distance is, the larger the collected portrait of the user is, and the larger the proportion of the front video picture in the main picture area is.

Specifically, when the first video picture acquired by the first camera in real time contains a portrait, the second video picture acquired by the second camera can be used as a background picture, and after the portrait is divided from the first video picture, the first terminal merges the divided portrait into the second video picture.

For example, the front camera and the rear camera of the first terminal simultaneously capture video pictures, the first terminal uses the video pictures captured by the rear camera as background pictures, and the portrait and the body part in the video pictures captured by the front camera are merged into the video pictures captured by the rear camera. Therefore, the background picture is a real, dynamic and real-time picture, and compared with a mode of integrating the portrait into a preset background picture, the user can carry out video call in a real, dynamic and real-time collected scene, and particularly in journey and outdoor activities, the user can experience the aesthetic feeling of people in the midstream of drawing, the interactive feeling is stronger, and the interactive effect of video call is better.

In one embodiment, in order to make the effect of the fusion picture more real and make the interaction feel stronger, the first terminal may further perform scaling processing on the portrait extracted from the front-facing camera, so that the portrait fused into the background picture is more real, and the situation of fusion picture distortion caused by too large portrait and too small background picture or too small portrait and too much background picture is avoided. Specifically, the smaller the distance between the front camera and the user portrait, the larger the collected user portrait, and vice versa, so that the first terminal can obtain the distance between the front camera and the user in real time, determine the scaling of the user portrait and the body part extracted from the front video image according to the distance, perform scaling processing on the user portrait and the body part according to the scaling, and blend the user portrait and the body part obtained after scaling processing into the video image collected by the rear camera to obtain a blended image.

In one embodiment, the first terminal can also send the fusion picture to the second terminal, and the second terminal can show the fusion picture to the other party of the call, so that both parties of the call can see the fusion picture, and when the first user makes a video call with the other party, the first user does not need to repeatedly switch the camera for showing the landscape picture again in order to show the first user, thereby improving the video call effect.

In one embodiment, the first terminal may display a video picture acquired by a camera of the second terminal in real time in the secondary picture area of the interaction area. Optionally, when the second terminal is provided with only one camera or only one camera is turned on, the first terminal displays a video picture acquired by the camera in real time in the secondary picture area of the interactive area. Optionally, when the second terminal turns on two cameras, the first terminal displays at least one of the video pictures acquired by the two cameras in real time in a secondary picture area of the interaction area, for example, the video picture acquired by the rear camera of the second terminal is only displayed in the secondary picture area, or the video pictures acquired by the front camera and the rear camera of the second terminal are simultaneously displayed in the secondary picture area.

Fig. 10 is a schematic interface diagram of an interaction area of a video call in one embodiment. Referring to fig. 10, in the interface diagram, an interactive area is divided into a main screen area 1002 and a sub screen area 1004.

In one embodiment, as shown in fig. 14, a timing diagram of two-way video data processing during a video call in one embodiment is shown. Referring to fig. 14, since the camera is started and the camera collects video data more time-consuming, in order to ensure user experience of a user in a video call process, a main thread is used for responding to a trigger operation of the user and processing the video data, and a collection thread is used as a sub-thread and is used for interacting with the camera, for example, the camera collects video pictures before and after the camera is started or the camera collects video surfaces before and after the camera is closed, and sends the collected video data to the main thread for processing. The life cycles of the main thread and the sub-thread are not affected.

Referring to fig. 14, after a user initiates a video call, a main thread sends initial video acquisition parameters to an acquisition thread in response to the operation of the user, where the initial video acquisition parameters may include a resolution, a frame rate, a data stream mode, and an on or off state of two cameras, where the resolution, the frame rate, and the data stream mode may be determined according to the device performance of the current terminal. After the acquisition thread returns that the initialization is successful, the main thread informs the acquisition thread to start acquiring video data by using the data acquisition module, the acquisition thread starts the front camera and the rear camera to acquire the video data and returns the acquired video data to the data acquisition module in the main thread, and after the main thread preprocesses the video data by using the data preprocessing module, the main thread displays a video picture by using the display module and transmits the video data by using the network module. And after the user finishes the video call, the main thread responds to the triggering operation of the user to inform the acquisition thread of finishing the acquisition of the video data, and the acquisition thread feeds back to the main thread to close the video data acquisition.
