The audio circuit 160 may transmit the received electrical signal converted from audio data to the speaker 161, and the electrical signal is converted into a sound signal by the speaker 161 to be output; on the other hand, the microphone 162 converts the collected sound signal into an electrical signal, receives the electrical signal from the audio circuit 160, converts the electrical signal into audio data, outputs the audio data to the processor 180 for processing, transmits the audio data to, for example, another terminal device via the RF circuit 110, or outputs the audio data to the memory 120 for further processing.

WiFi belongs to a short-distance wireless transmission technology, and terminal equipment can help a user to send and receive emails, browse webpages, access streaming media and the like through a WiFi module 170, so that wireless broadband Internet access is provided for the user. Although fig. 1 shows a WiFi module 170, it is understood that it does not belong to the essential constitution of the terminal device, and can be omitted entirely as required within the scope of not changing the essence of the invention.

It can be understood that, in the embodiment of the present application, in the case that the terminal device is a user terminal and a service tool, the terminal device includes a bluetooth module. It will be understood that the bluetooth module does not belong to the essential constitution of the terminal device, and may be omitted entirely as required within the scope of not changing the essence of the invention, for example, the bluetooth module may not be included in the server.

Although not shown, the terminal device further includes a camera. Optionally, the position of the camera on the terminal device may be front, rear, or internal (which may extend out of the body when in use), which is not limited in this embodiment of the present application.

Fig. 2 is a block diagram illustrating a software configuration of the terminal device 100 according to the embodiment of the present application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages. As shown in fig. 2, the application package may include camera, gallery, phone, map, phone, music, settings, mailbox, video, social, etc. applications.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layer may include a window manager, a content provider, a resource manager, a view system, a notification manager, and the like.

The window manager is used for managing window programs. The window manager may obtain the display screen size, determine if there is a status bar, lock the screen, touch the screen, drag the screen, intercept the screen, etc.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the terminal equipment vibrates, and an indicator light blinks.

Android runtimes include core libraries and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The workflow of terminal equipment software and hardware is illustrated below in connection with the scenario of terminal equipment interface switching.

When a touch sensor in the terminal equipment receives touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, touch strength, time stamp of the touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a camera application icon, calling an interface of an application framework layer by the camera application, starting the camera application, and further starting a display driver by calling a kernel layer to display a functional interface of the camera application.

When the camera application is started, the camera application can call a camera access interface in an application program framework layer, start a shooting function of a camera, and drive one or more cameras to acquire one or more frames of images in real time based on camera driving of a kernel layer. After the camera acquires the image, the image can be transmitted to the camera application in real time through the kernel layer, the system library and the application program framework layer, and then the camera application displays the image to a corresponding functional interface.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be implemented independently or combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

In order to improve user experience, terminal devices such as mobile phones and tablet computers are generally configured with a plurality of cameras. The terminal device may provide a plurality of photographing modes, such as a front photographing mode, a rear photographing mode, a front and rear double photographing mode, a main angle mode, etc., for the user through the plurality of cameras configured. The user can select a corresponding shooting mode to shoot according to the shooting scene.

The principal angle mode can be understood as a mode that when the terminal equipment records the video, a portrait focus-tracking video can be additionally generated, namely, more than two videos are saved when the recording is completed, one of the videos is a recorded original video, and other videos are videos automatically cut from the original video according to the tracked target portrait. The person image in the person image focus tracking video can be understood as a "principal angle" focused by a user, and the manner of generating the video corresponding to the "principal angle" can be as follows: and cutting out video content corresponding to the main angle from the video conventionally recorded by the terminal equipment.

The "principal angle" may be a living body such as a person or an animal, or may be a non-living body such as a vehicle. It is understood that any item that can be identified based on an algorithmic model can be used as the "principal angle" in embodiments of the present application. In the embodiment of the present application, the "principal angle" may be defined as a focus tracking object, and the focus tracking object may also be referred to as a principal angle object, a tracking target, a tracking object, a focus tracking target, etc., which is not limited by the concept of the "principal angle".

For convenience of understanding, a main angle mode among photographing modes is described below with reference to the accompanying drawings.

Fig. 3A is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 3A, a terminal device 301, a person 302, and a person 303 are included in the application scene.

The terminal device 301 may record a video containing the tracking target through a camera. The tracking target can be any person recorded by a camera, or any object such as an animal, a car and the like. In the scene shown in fig. 3A, the tracking target may be the person 302 in the photographed image or the person 303 in the photographed image.

In the principal angle mode, the terminal equipment can additionally obtain one or more tracking target corresponding focus tracking videos while recording the videos.

Specifically, when the terminal device 301 previews in the principal angle mode, the terminal device 301 may receive an operation of setting a tracking target by the user, and after the terminal device 301 starts recording the video, one or more additional tracking videos may be generated based on the tracking target. The terminal device 301 may set the person 302 in the photographed screen as the tracking target, or may set the person 303 in the photographed screen as the tracking target, for example.

Alternatively, when the terminal device 301 records in the main angle mode, the terminal device 301 may additionally generate one or more tracking videos based on the tracking target, upon receiving an operation of setting the tracking target by the user. Thus, the focus tracking video corresponding to the tracking target can be obtained without manually editing the whole video.

It can be understood that the terminal device can switch the person corresponding to the tracking target one or more times during the video recording process. Specifically, when the terminal device receives the operation of switching the tracking target by the user, the terminal device switches the person corresponding to the tracking target.

In one possible implementation, when the person corresponding to the tracking target is switched, different persons exist in the focus tracking video obtained by the terminal device.

Illustratively, when the terminal device detects that the user switches the tracking target from person 302 to person 303 during recording, the terminal device displays a tracking screen based on person 303. In a focus tracking video generated based on a tracking target after recording is finished, displaying a character 302 correspondingly before the tracking target is switched; displaying the character 303 correspondingly after the tracking target is switched; it can also be understood that the portion before the tracking target is switched corresponds to the person 302, and the portion after the tracking target is switched corresponds to the person 303.

Specifically, taking the 3 rd second in the recording process of the focus tracking video, the terminal device detects that the user switches the tracking target from the person 302 to the person 303 as an example. In the focus tracking video generated based on the tracking target, the person 302 is correspondingly displayed in the focus tracking video before the 3 rd second; the person 303 is displayed in correspondence with the focus tracking video after the 3 rd second. Therefore, the terminal equipment can switch the tracking target, so that the switching of the characters in the focus tracking video is realized, and the user experience is improved.

In another possible implementation, when the person corresponding to the tracking target is switched, the terminal device may obtain one path of the focus tracking video based on the tracking target before switching, and obtain the other path of the focus tracking video based on the tracking target after switching.

Illustratively, when the terminal device detects that the user switches the tracking target from the person 302 to the person 303 during recording, the terminal device generates the focus tracking video 1 based on the person 302, and generates the focus tracking video 2 based on the person 303 after the tracking target is switched to the person 303.

In some embodiments, in the recording process of the video, the terminal device may also start and end recording of the focus tracking video multiple times, and additionally generate multiple paths of focus tracking videos.

Illustratively, in recording video 1, when the terminal device receives an operation that the user ends tracking person 303, the terminal device may generate a focus tracking video 2 based on the person 303. When the terminal device receives the operation of the user tracking the person 302 after finishing the operation of tracking the person 303, the terminal device 301 may additionally generate the focus tracking video 3 based on the person 302. At this time, in addition to the normally recorded video 1, the terminal device additionally generates 2 chasing videos (i.e., chasing video 2 and chasing video 3). The embodiment of the application does not limit the number of the focus tracking videos.

Therefore, the terminal equipment can start and end recording of the focus tracking video for a plurality of times, generate a plurality of paths of focus tracking videos based on the tracking target, and improve user experience.

It should be noted that, in the scene shown in fig. 3A, the video recorded by the terminal device through the camera includes two characters. More or fewer characters may be included in the video of the terminal device. The number of characters recorded by the terminal equipment is not particularly limited.

It should be noted that, when the terminal device previews and records in the main angle mode, the operation of setting the tracking target by the user is not received, and when the recording is finished, a path of video can be obtained. When the terminal equipment receives the operation of setting the tracking target by the user through the main angle mode preview and then receives the operation of closing the small window by the user, the terminal equipment cancels the tracking of the tracking target, if the operation of setting the tracking target by the user is not received during recording, and when the recording is finished, one path of video can be obtained. It is understood that the principal angle mode may be provided in an application having a photographing function such as a camera. After the terminal device enters the main angle mode, the implementation of the main angle mode may include a preview mode and a recording mode.

It should be noted that, the interface displayed by the terminal device in the preview mode (before recording) and the recording mode (during recording) may be referred to as a preview interface; the pictures displayed in the preview interface of the preview mode (before recording) are not generated and saved; the pictures displayed in the preview interface of the recording mode (during recording) can be generated and saved. For convenience of distinction, hereinafter, a preview interface of a preview mode (before recording) is referred to as a preview interface; the preview interface of the recording mode (during recording) is referred to as a recording interface.

In the preview mode of the home angle mode, an image (preview screen) obtained by the camera may be displayed in the preview area, and an image (trace screen) of the trace target selected by the user may be displayed in the small window. In the preview mode, the terminal device may not generate a video, or may not store the content displayed in the preview area and the content displayed in the small window.

For example, a preview interface of the principal angle mode in the terminal device may be as shown in fig. 3B. The preview interface includes a preview area 304, a recording control 305.

The preview area 304 displays a preview screen. When the terminal device recognizes that a person is included in the preview screen, a tracking frame (e.g., tracking frame 307 and tracking frame 308) is displayed in the preview area. The tracking frame can prompt the user that the corresponding person can be set or switched to the tracking target, and the user can conveniently set or switch the tracking target. When the terminal device recognizes that a plurality of persons are included in the preview screen, the preview area may be displayed with a plurality of tracking frames. The number of tracking frames is less than or equal to the number of people identified by the terminal device. The tracking target is any one of a plurality of persons corresponding to the tracking frame in the preview screen. The tracking target may be referred to as a focus tracking object, a principal angle object, or the like, which is not limited in the present application.

In some embodiments, the tracking box (e.g., tracking box 307) corresponding to the person set to track the target is different from the tracking box display style corresponding to the person not set to track the target (e.g., tracking box 308). In this way, the user can distinguish and identify the tracked person (tracked target) conveniently. In addition to the different patterns of the tracking frames, the embodiments of the present application may also set the colors of the tracking frames, for example, the colors of the tracking frame 307 and the tracking frame 308 are different. Thus, the tracking target can be intuitively distinguished from other people. The trace box may be a virtual box, such as trace box 307; the combination of the virtual box and "+" is also possible, such as the tracking box 308, which may be any display form, and the tracking box may be satisfied by a function that can be triggered by a user to implement tracking and may be set as a tracking target. The tracking frame may be marked at any location of a person that may be set to track a target, as embodiments of the present application are not particularly limited.

It can be understood that the tracking frame is one of the tracking identifiers, and the terminal device can also display other forms of tracking identifiers, so as to facilitate the user to set the tracking target. By way of example, other forms of tracking identification may be thumbnails of objects, numbers, letters, graphics, and the like. The tracking mark may be provided at any position of the object, may be provided near the object, or may be provided at the edge of the preview area. The embodiment of the application does not specifically limit the specific location of the tracking identifier.

For example, the terminal device may display a thumbnail arrangement of one or more objects at an edge of the preview area, and when the terminal device receives an operation that the user clicks any tracking identifier, set the object corresponding to the clicked tracking identifier as a tracking target.

In a possible implementation manner, the terminal device may identify the person through face recognition technology and display the tracking frame. The terminal device may determine the display position of the tracking frame, for example, a position where the body of the person is relatively centered, according to a technique such as human body recognition. Therefore, based on the position of the human body calculation tracking frame, the situation that the tracking frame is located at the position of the human face can be reduced, shielding of the tracking frame to the human face can be reduced, and user experience is improved. The technology used for the identification technology of the person and the tracking frame position calculation in the embodiment of the present application is not particularly limited.

In some embodiments, fig. 3B also includes a widget 306. The widget 306 displays a tracking screen. The tracking screen corresponds to a tracking target. When the tracking target is switched, the person in the tracking screen displayed in the widget 306 is switched. For example, if the tracking target is switched from the person corresponding to the tracking frame 307 to the person corresponding to the tracking frame 308, the tracking screen displayed in the widget 306 is changed accordingly.

The tracking screen may be part of a preview screen. In a possible implementation manner, the tracking picture is obtained by the terminal device cutting the preview picture according to a certain proportion based on the tracking target. The embodiment of the application does not specifically limit the frame displayed by the small window.

In some embodiments, the specification, position, horizontal and vertical screen display modes and the like of the small window are adjustable, and a user can adjust the style of the small window according to video habits.

In some embodiments, widget 306 further includes a close control 309 and a first switch control 310.

It can be understood that, when the terminal device receives the operation of setting the tracking target by the user, a small window is displayed on the preview interface to display the tracking screen of the tracking target. And when the terminal equipment does not receive the operation of setting the tracking target by the user, the preview interface does not display a small window.

Optionally, the tracking target is centrally displayed in the tracking screen.

Optionally, the small window floats above the recording area. And are not limited herein.

When the user triggers the close control 309 through clicking, touching, or other operations in the preview interface shown in fig. 3B, the terminal device receives the operation of closing the widget, closes the widget, and cancels the preview of the tracking target.

When the user triggers the first switching control 310 through clicking, touching, or other operations in the preview interface shown in fig. 3B, the terminal device receives an operation of switching the widget display mode (widget style), and the terminal device switches the style of the widget. In particular, the porthole may be switched from landscape to portrait or vice versa.

When the user triggers the recording control 305 through clicking, touching or other operations on the preview interface shown in fig. 3B, the terminal device receives an operation of starting recording, and starts recording video and tracking video.

Optionally, the preview interface may also include other controls, such as a main angle mode exit control 311, a setup control 312, a flash control 313, a widget style control 314, a zoom control 315, and the like.

When the main angle mode exit control 311 is triggered, the terminal device exits the main angle mode and enters the video recording mode. When the setting control 312 is triggered, the terminal device may adjust various setting parameters. The setting parameters include, but are not limited to: whether to turn on a watermark, store a path, a coding scheme, whether to save a geographic location, etc. When the flash control 313 is triggered, the terminal device may set a flash effect, for example, control the flash to be forcibly turned on, forcibly turned off, turned on at photographing, turned on according to environmental adaptation, and the like. When the zoom control 315 is triggered, the terminal device may adjust the focal length of the camera, thereby adjusting the magnification of the preview screen.

When the user triggers the second switching control 314 through clicking or touching on the preview interface shown in fig. 3B, the terminal device receives the operation of setting the widget style, and displays the widget style selection item for the user to select. The widget style selections include, but are not limited to: transverse or vertical, etc. The embodiments of the present application are not limited in this regard. In a possible implementation, the second switching control 314 corresponds to a display style of the widget, so that the user can distinguish the widget style conveniently.

It should be noted that, in the preview interface shown in fig. 3B, the widget style switching may be controlled by the first switching control 310, and the widget style switching may also be controlled by the second switching control 314. In a possible implementation, the first switch control 310 in the widget may be set in linkage with the second switch control 314 of the preview area. For example, when the widget is changed from landscape to portrait, the icon of the first switch control 310 is in the portrait preview style, and the icon of the second switch control 314 is also in the portrait preview style, or the icons of the first switch control 310 and the second switch control 314 are both in the landscape preview style, the user is prompted to click the preview style after the switch again.

It can be appreciated that in the preview scenario, after the terminal device sets the tracking target, the tracking screen of the widget may display the tracking target centrally. In some scenarios, the tracking target may be in a moving state, and when the tracking target moves but does not leave the lens, the tracking screen of the widget may continuously display the tracking target centrally.

For example, the preview interface may be configured such that the tracking target object includes a male character and a female character, and the terminal device sets the male character as a tracking target in response to a click operation of a tracking frame for the male character by the user, and enters the interface as shown in a in fig. 3B. In the interface shown in a in fig. 3B, the tracking screen of the small window displays a male character centered on the right side of the female character. The male character moves, and the terminal device can continuously focus on the male character and display the male character in the small window in a centered manner. When the male character walks to the left of the female character, the interface of the terminal device may be as shown in B of fig. 3B. In the B interface in fig. 3B, the tracking screen of the small window still displays a male character centered on the left side of the female character.

In a possible implementation manner, when the terminal device tracks the target, the focus moves along with the movement of the tracked target, and illustratively, in the interface shown as a in fig. 3B, the focus is located in the face area of the male character and is located in the middle right part of the screen; the male character moves, the terminal device can continue to focus on the male character, and when the male character walks to the left of the female character, the interface of the terminal device can be as shown in B of fig. 3B. In the interface shown in B in fig. 3B, the focus is located in the face region of the male character, in the middle left portion of the screen.

In the recording mode of the main angle mode, the terminal device can display an image (recording picture) obtained by the camera in a recording area, display an image (tracking picture) of a tracking target selected by a user in a small window, and generate a recording video and a focus tracking video which are recorded after the recording mode is started. And at the end of recording, the terminal equipment stores the video generated based on the recorded picture and the focus tracking video generated based on the tracking picture.

In some embodiments, the window may end the recording in advance compared to the recording of the recording area. And when the small window recording is finished, the terminal equipment stores the tracking video generated based on the tracking picture. Or it is understood that the terminal device may end the recording of the focus-following video in advance compared to the whole video.

In some embodiments, the small window may delay the start of recording compared to the recording of the recording area. Or it can be understood that after the terminal device starts to record the video, the terminal device starts to open a small window and starts to record the focus tracking video after detecting the operation of setting the tracking target by the user.

For example, the recording interface of the main angle mode in the terminal device may be as shown in fig. 3C. The recording interface includes a recording area 316, a pause control 317, and an end control 318.

Recording area 316 displays a recording picture and a recording duration. When the terminal device recognizes that a person is included in the recording screen, the recording area displays tracking frames (e.g., tracking frame 320 and tracking frame 321). It will be appreciated that the number of tracking frames is less than or equal to the number of people identified by the terminal device.

In some embodiments, the recording interface also displays a widget 319. The widget 319 displays a tracking screen. The tracking screen corresponds to a tracking target. When the tracking target is switched, the person in the tracking screen displayed in the small window 319 is switched. For example, if the tracking target is switched from the person corresponding to the tracking frame 320 to the person corresponding to the tracking frame 321, the tracking screen displayed in the small window 319 is changed accordingly.

The tracking frames may be part of the recording frames. In a possible implementation manner, the tracking picture is obtained by cutting the recording picture in real time according to a certain proportion based on the tracking target. The embodiment of the application does not specifically limit the frame displayed by the small window.

Optionally, the tracking target is centrally displayed in the tracking screen.

The widget 319 also includes a widget end control 322 and a widget recording duration.

It can be understood that, when the terminal device receives the operation of setting the tracking target by the user, a small window is displayed on the recording interface to display the tracking picture of the tracking target. When the terminal equipment does not receive the operation of setting the tracking target by the user, the recording interface does not display a small window.

When the user triggers the end control 318 through clicking, touching or other operations on the recording interface shown in fig. 3C, the terminal device receives the operation of ending recording by the user, and the terminal device enters the preview interface in the main angle mode, stores the video corresponding to the recording picture, and the focus tracking video corresponding to the tracking picture.

When the user triggers the pause control 317 by clicking, touching, etc. on the recording interface shown in fig. 3C, the terminal device receives the operation of the user to pause recording, and the terminal device pauses recording of video in the recording area 316 and recording of the focus-following video in the small window 319.

When the user triggers the widget ending control 322 through clicking, touching or other operations on the recording interface shown in fig. 3C, the terminal device receives the operation of ending the widget recording by the user, and the terminal device continues to display the recording picture in the recording area 316, closes the widget 319 and stores the focus tracking video corresponding to the tracking picture in the widget 319.

In a possible implementation, the recording interface further includes a flash control 323. When the flash control 323 is triggered, the terminal device can set a flash effect.

It can be understood that when the terminal device records in the main angle mode, a path of video can be generated based on the recording picture of the recording area, and a path of tracking target corresponding to the tracking video can be additionally generated based on the tracking picture of the small window. The two paths of videos are independently stored in the terminal equipment. Therefore, the video corresponding to the tracking target can be obtained without manually editing the whole video later, the operation is simple and convenient, and the user experience is improved.

It can be understood that, in the recording scenario, after the terminal device sets the tracking target, the tracking screen of the widget may display the tracking target centrally. In some scenarios, the tracking target may be in a moving state, and when the tracking target moves but does not leave the lens, the tracking screen of the widget may continuously display the tracking target centrally.

For example, the preview interface may be configured such that the tracking target object includes a male character and a female character, and the terminal device sets the male character as a tracking target in response to a click operation of a tracking frame for the male character by the user, and enters the interface as shown in a in fig. 3C. In the interface shown in a in fig. 3C, the tracking screen of the small window displays a male character centered on the right side of the female character. The male character moves, and the terminal device can continuously focus on the male character and display the male character in the small window in a centered manner. When the male character walks to the left of the female character, the interface of the terminal device may be as shown in b of fig. 3C. In the B interface in fig. 3B, the tracking screen of the small window still displays a male character centered on the left side of the female character.

In a possible implementation manner, when the terminal device tracks the target, the focus moves along with the movement of the tracked target, and in an interface shown in a in fig. 3C, the focus is located in the face area of the male character and is located in the middle right part of the screen; the male character moves, the terminal device can continue to focus on the male character, and when the male character walks to the left of the female character, the interface of the terminal device can be as shown in b of fig. 3C. In the interface shown in b in fig. 3C, the focus is located in the face area of the male character, in the middle left portion of the screen.

It can be appreciated that, in the embodiment of the present application, a shooting mode in which one or more tracking videos can be additionally generated based on a tracking target is defined as a principal angle mode, and the shooting mode may also be referred to as a tracking mode, which is not limited in the embodiment of the present application.

The video preview interface comprises: preview area, recording parameter selection item and shooting mode selection item. The preview area displays a preview picture in real time; recording parameter options include, but are not limited to: a main angle mode 503, a flash, a filter, a setting, or other types of recording parameter selections. Shooting mode selection items include, but are not limited to: portrait, photograph, video, professional or other types of photography mode selections.

When the user triggers the principal angle mode 503 through clicking, touching or other operations on the video preview interface shown in c in fig. 5, the terminal device receives the operation of selecting the principal angle mode preview by the user, and enters the preview interface corresponding to the principal angle mode shown in d in fig. 5. The preview interface includes: preview area and recording control. The preview area displays a preview screen. When the person exists in the preview screen, a tracking frame is also displayed in the preview area. When the user triggers the tracking frame through clicking or touching operation, the terminal device receives the operation of setting the tracking target, sets the person corresponding to the tracking frame as the tracking target, and displays the tracking picture corresponding to the tracking target on the display interface through the small window.

It can be understood that when the terminal device enters the main angle mode, the terminal device can be horizontally placed in a horizontal screen state or can be vertically placed in a vertical screen state, and the principle that the terminal device realizes the main angle mode is similar in the horizontal screen state or the vertical screen state.

It can be understood that in the main angle mode of the camera, the terminal device may select the tracking target after starting recording, or may select the tracking target before starting recording the video. The following describes two recording processes with reference to fig. 6 and 7, respectively. Fig. 6 is an interface schematic diagram corresponding to a main angle mode recording flow provided in an embodiment of the present application.

When the user triggers the recording control 601 through clicking, touching or the like in the preview interface shown in a in fig. 6, the terminal device receives an operation of starting recording, and enters the recording interface shown in b in fig. 6. The recording interface includes: recording area 602, pause control 603, end control 604. The recording area displays a recording screen and a tracking frame 605. The tracking frame 605 may facilitate user selection of a tracking target.

When the user triggers the tracking frame 605 through clicking, touching, etc. operations in the recording interface shown in b in fig. 6, the terminal device receives the operation of setting the tracking target by the user, and the terminal device enters the recording interface shown in c in fig. 6, where the recording interface includes: a recording area, a pause control 606, an end control 607, a widget 608. The recording area displays a recording picture. The widget 608 includes a widget end control 609. The small window 608 displays a tracking screen corresponding to the tracking target. The tracking picture corresponding to the tracking target is a part of the recording picture.

On the basis of the flow shown in fig. 6, when the user triggers the pause control 606 through clicking or touching the recording interface shown in fig. 6 c, the terminal device receives the operation of suspending video recording, and the video recording is suspended, and the focus tracking video corresponding to the small window is also suspended.

When the user triggers the widget 608 through a drag operation in the recording interface shown in fig. 6 c, the widget 608 position may be moved.

The moving distance of the widget 608 is related to the distance between the drag operation start position and the drag operation end position, and the moving direction of the widget 608 is related to the direction of the drag operation.

Fig. 7 is an interface schematic diagram corresponding to a main angle mode recording flow provided in an embodiment of the present application.

When the user triggers the tracking frame 701 by clicking, touching, or the like in the preview interface shown in a in fig. 7, the terminal device receives an operation of setting a tracking target by the user, and enters the preview interface shown in b in fig. 7. The preview interface includes: preview area 702, recording control 703 and widget 704. The recording area displays a preview picture. The widget 704 displays a tracking screen. The tracking screen corresponds to a tracking target. The widget 704 also includes a close control 705 and a first switch control 706.

When the user triggers the recording control 703 through clicking, touching or other operations in the preview interface shown in b in fig. 7, the terminal device receives an operation of starting recording, and enters the recording interface shown in c in fig. 7. The recording interface includes: a recording area, a pause control 707, an end control 708, and a widget 709. The recording area displays a recording picture. Widget 709 includes widget ending control 710. The small window 709 displays a tracking screen corresponding to the tracking target. The tracking frame is a part of the recording frame.

The roles of pause control 707, end control 708, and widget 709 may be referred to in the relevant description of fig. 6 and will not be repeated here.

On the basis of the flow shown in fig. 7, when the user triggers the close control 705 by clicking, touching or the like in the preview interface shown in b in fig. 7, the terminal device receives the operation of closing the widget, closes the widget, and cancels the preview of the tracking target.

When the user triggers the first switching control 706 of the recording control through clicking, touching or other operations in the preview interface shown in b in fig. 7, the terminal device receives the operation of switching the display mode of the small window, and the terminal device switches the display mode of the small window. In particular, the portlets may be switched from landscape to portrait or vice versa.

In a possible implementation, the terminal device may also adjust the size of the small window. The embodiment of the application does not limit a specific implementation manner of the size adjustment of the small window.

The terminal equipment can start the focus tracking video recording of the small window based on the scene and obtain multiple paths of videos. It should be noted that, the small window may display the picture related to the tracking target in the preview area/recording area, but the video recorded by the small window and the video recorded by the recording area are multiple independent videos, and are not a composite video in the form of picture-in-picture in which the tracking picture of the small window is nested in the recording picture of one recording area.

It should be noted that, if the terminal device does not open the recording of the small window, the terminal device may obtain a path of video recorded in the recording area. If the terminal equipment starts the small window recording, the terminal equipment can obtain one path of video recorded in the recording area and one path or multiple paths of video recorded in the small window. For example, during the video recording in the recording area, the terminal device may open the window recording multiple times, where the terminal device may end the recording of the window when detecting the clicking operation for the window ending control, and obtain one video. After the small window is opened again for recording, the terminal equipment can obtain a new video. The number of videos obtained by the terminal device based on the small window can be related to the number of times the small window is opened for recording.

Optionally, the user may browse the videos recorded in the recording area and the multiple videos recorded in the small window based on the album of the camera application, and the display sequence of the multiple videos may be the recording sequence of the videos, that is, the terminal device may sort the videos according to the ending time point or the starting time point of the recorded videos. The display sequence of the multiple paths of videos can be the reverse sequence of video recording, namely, the terminal equipment can be arranged in the reverse sequence according to the ending time or the starting time of video recording.

Alternatively, the video recorded in the recording area and the video recorded in the small window may be displayed in a video thumbnail of the same album interface. In order to facilitate distinguishing the video recorded in the recording area from the video recorded in the small window, the terminal device may set an identifier for the video recorded in the small window. For example, the terminal device may add an outer border, a font, a graphic, and the like to the video recorded in the small window, and may further set the size of the video thumbnail recorded in the small window, so that the small window and the video thumbnail recorded in the recording area have a size difference. It can be appreciated that the embodiment of the application does not limit the form of the video thumbnails in the album, the arrangement sequence of the video thumbnails, the storage sequence of the video, and the like.

It should be noted that, in some scenarios where the terminal device records a video, the user may want to only pay attention to the recorded content, and not want to have other unrelated content, so as not to generate interference and reduce the experience effect.

In the recording process after the terminal device enters the main angle mode, the terminal device can hide some elements in the recording interface, such as a tracking frame, a small window ending control, a small window and the like. Therefore, shielding of recorded pictures is reduced, interference is reduced, and user experience is improved.

In a possible implementation manner one, when the recording area does not receive the user operation within a first preset time period after the video recording is started, the tracking frame is hidden and not displayed; or the user operation is not received in the first preset time after the random operation of the user is received in the recording area, and the tracking frame is hidden and not displayed. And when the terminal equipment receives the user operation, displaying a tracking frame.

It can be understood that the first preset duration may be 3s or 5s, and the specific value of the first preset duration is not limited in this embodiment of the present application.

The hiding and displaying of the tracking frame is described below with reference to fig. 8 and 9.

Fig. 8 is a schematic diagram of a recording interface in a main angle mode according to an embodiment of the present application.

Taking the first preset duration of 5 seconds(s) as an example, the recording interface shown in a in fig. 8 includes: recording area 801, pause control, end control, recording duration, and widget 802. The recording area 801 displays a recording screen and tracking frame 803. The widget 802 displays a tracking screen. Widget 802 also includes a widget recording duration and a widget ending control.

When the terminal device does not receive the operation of any position of the recording area within the first preset time period after the terminal device starts to record the video, the terminal device enters the recording interface shown by b in fig. 8 from the recording interface shown by a in fig. 8. The recording interface includes a recording area 804, a pause control 805, an end control, a recording duration, and a widget. Recording area 804 displays a recording picture without displaying a tracking frame; the small window displays a tracking screen.

Therefore, the terminal equipment can hide the tracking frame, reduce shielding of recorded pictures and improve user experience.

On the basis of the embodiment, when the tracking frame is hidden, the terminal device displays a tracking frame display prompt.

Illustratively, the interface shown in b in fig. 8 further includes: the tracking box displays a prompt 806. The tracking frame display prompt is used for prompting the display mode of the user tracking frame. The tracking frame display prompt may be "click recording area displayable tracking frame". The embodiment of the application does not limit the position, the display form, the specific content and the like of the display prompt display of the tracking frame.

It can be understood that the tracking frame display prompt disappears after the second preset time period is displayed, or when the terminal device receives the user operation in the recording area, the tracking frame is displayed, and the tracking frame display prompt disappears. The second preset duration may be 3s or 5s, and the specific value of the second preset duration is not limited in this embodiment of the present application.

Therefore, the display prompt of the tracking frame can disappear, shielding of the recorded picture is reduced, interference is reduced, and user experience is improved.

It can be understood that, in the recording process, the terminal device only displays the tracking frame display prompt when the tracking frame is first hidden, and also can display the tracking frame display prompt when the tracking frame is hidden each time. The terminal device may further limit the number of times the tracking frame displays the prompt during one recording. The embodiment of the application does not limit the display times, display frequency and the like of the display prompts of the tracking frame in the one-time recording process.

In some embodiments, the terminal device displays the tracking frame display prompt only when the user first records using the principal angle mode. The terminal device may also display a tracking frame display prompt each time the user records using the principal angle mode. The terminal device can also display a tracking frame display prompt in the previous N recording processes. The embodiment of the application does not limit the display times, display frequency and the like of the display prompt of the tracking frame.

On the basis of the embodiment, when the terminal equipment receives operations such as clicking, touching and the like at any position of the recording area, the terminal equipment displays a tracking frame; or when receiving the operation of suspending recording, the terminal equipment displays a tracking frame; or when the tracking target is lost, the terminal device displays a tracking frame.

Illustratively, when the user triggers any position of the recording area 804 through clicking, touching, or other operations on the recording interface shown in b in fig. 8, the terminal device receives an operation of canceling the immersive experience, and enters the recording interface shown in c in fig. 8. A tracking box 807 is displayed in the recording interface.

Therefore, the terminal equipment can also call out the tracking frame, so that the tracking target can be conveniently confirmed, the tracking target can be switched, and the user experience is improved.

It can be appreciated that when the terminal device does not receive any operation within the first preset time period after receiving the operation of clicking the recording area 804 by the user, the terminal device hides the tracking frame again and does not display the tracking frame.

Illustratively, when the user triggers the pause control 805 by clicking, touching, or the like on the recording interface shown in b in fig. 8, the terminal device receives an operation to pause recording, and enters the pause recording interface shown in d in fig. 8. The pause recording interface includes: a recording area, a start control 808, an end control, and a widget. The recording area displays a recording screen, a tracking frame 809, and a recording duration. The small window displays a tracking screen. The widget also displays a widget ending control and a widget recording time length. The recording time displayed by the recording area and the small window recording time are not changed. Under the condition of suspending recording, the recording duration of the recording area and the small window recording duration can be expressed as a combination of "|" and time.

When the user triggers the start control 808 through clicking, touching or other operations on the recording interface shown in d in fig. 8, the terminal device receives the operation of continuing recording, and continues recording video and tracking video.

It will be appreciated that when the terminal device pauses recording, the recording area may display a frame of recording before the pause recording, or display the photographed picture in real time. When the terminal equipment pauses recording, the small window may display a frame of tracking picture before pausing recording; or a covered state is changed; or the tracking screen is displayed in real time. The embodiment of the application does not limit the display of the recording area, the display of the small window, and the like when the terminal equipment pauses recording.

It will be appreciated that the frames displayed by the recording area during the pause of recording video will not be saved in the video and the tracking frames displayed by the small window during the pause of recording video will not be saved in the in-focus video. The video after pause and the video before pause of the recording area are the same video, the focus tracking video after pause of the small window and the focus tracking video before pause are the same focus tracking video, for example, a user clicks a pause recording control when the recording time length is 4s, the terminal equipment responds to the click operation and pauses video recording, and the video recording time is 4s. After a period of time, when the terminal equipment receives clicking operation for starting the control, the terminal equipment starts recording the 5 th s video on the basis of the 4s video, and the recording duration is correspondingly changed.

Based on the embodiment shown in fig. 8, when the tracking target is lost, the terminal device may suspend recording of the in-focus video. It will be appreciated that the terminal device may lose track of the target for a number of reasons, and that no target is tracked on the recorded picture. Various reasons include, but are not limited to: tracking movement of a target, movement of a terminal device, or small window style switching (e.g., switching from landscape to portrait or vice versa), etc.

Fig. 9A is a schematic diagram of a scenario for tracking target loss according to an embodiment of the present application.

The recording interface shown as a in fig. 9A includes: recording area 901, pause control, end control, recording duration, and widget 902. The recording area 901 displays a recording screen, and does not display a tracking frame. The widget 902 displays a tracking screen for tracking a target.

When the tracking target is lost and the tracking target is not in the recording picture, the terminal device enters the recording interface shown in b in fig. 9A. The recording interface includes: a recording area 903, a pause control, an end control, and a widget 904. The recording area 903 displays a recording screen and a tracking frame 905.

It will be appreciated that there are a number of ways in which the terminal device can handle when the tracking target is lost. The various ways of treatment include, but are not limited to: continuously recording a focus tracking video; suspending recording of the focus tracking video; suspending recording of the focus tracking video when the tracking target is not found within the eighth preset time period; and finishing recording the tracking video when the tracking video is not retrieved within the ninth preset time period.

Accordingly, the widget may continue to display a portion of the content in the recorded picture; or may display a frame of picture before the tracking target is lost; the method further comprises the steps of continuously displaying part of content in the recorded picture within an eighth preset time length, and displaying a frame of picture corresponding to the eighth preset time length when the eighth preset time length is reached; or the partial content in the recorded picture may be continuously displayed within the ninth preset time period, and the small window disappears when the ninth preset time period arrives.

In a possible implementation manner, when the tracking target is lost, the small window can suspend a layer of covering, and a covering state with lower brightness than that of the recording picture of the large window is presented, so as to remind a user of abnormal recording of the small window.

In some embodiments, after the tracking target is lost, the widget may continue recording the picture of the position of the tracking target before the tracking target is lost, where the recorded picture may be an empty mirror that does not include the tracking target, and the recording time may be an eighth preset duration.

When the tracking target is retrieved and recording is restored, the terminal equipment can clip the video before the tracking target is lost, the empty mirror video and the video after the tracking target is retrieved. In one possible implementation, the terminal device may delete the empty mirror, and splice the video before the tracking target is lost and the video after the tracking target is retrieved to synthesize a path of video. In another possible implementation, the terminal device can perform blurring, soft focus, addition of a cover layer and the like on the empty mirror video, so that the influence of the empty mirror video on the continuity of the whole video is reduced, and the experience of a subsequent user for viewing the recorded video is improved.

Optionally, when the tracking target is lost, the terminal device further displays a loss prompt. The loss prompt is used to prompt the user that the target is lost, for example, the content of the loss prompt may be "target lost". Missing cues may also be used to indicate the manner in which the widget is processed. For example, the content of the loss hint may be "target lost, pause the chasing video after 5 seconds.

Illustratively, the recording interface shown at b in fig. 9A also includes a loss hint 906. The widget 904 displays a loss prompt 906. The content of the loss hint 906 is "target lost".

Optionally, a loss hint 906 may also be displayed in the recording area 903. The embodiment of the application does not limit the specific content, the display position and the like of the loss prompt.

It can be understood that the missing cue disappears after the third preset time period is displayed, or when the terminal device is retrieving the tracking target or switching the tracking target. The third preset duration may be 3s or 5s, and the specific value of the third preset duration is not limited in this embodiment of the present application.

It can be understood that after the tracking target is lost, the terminal device may stop recording the tracking video after the fourth preset duration; alternatively, recording of the focus tracking video may be stopped when the tracking target is lost.

For example, taking the fourth preset duration as 5 seconds as an example, if the terminal device does not retrieve the tracking target or receives the operation of switching the tracking target, the terminal device enters the recording interface shown in c in fig. 9A from the recording interface shown in b in fig. 9A. The recording interface includes: a recording area 907, a pause control, an end control, and a widget 908. The recording area displays a recording screen, a tracking frame 909, and a recording time length. The widget 908 also displays a widget end control and a widget recording duration.

The embodiment of the application does not limit the display of the recording area, the display of the small window, and the like when the terminal equipment pauses recording.

It will be appreciated that the tracking frames displayed by the widget during the pause recording are not saved in the in-focus video. The focus tracking video after the small window is paused is the same focus tracking video as the focus tracking video before the small window is paused, for example, when the small window recording time length is 4s, recording is paused, and the focus tracking video recording time is 4s. When the terminal equipment retrieves the tracking target or switches the tracking target, the terminal equipment starts recording the 5s tracking video on the basis of the 4s video, and the recording time length is correspondingly changed.

Optionally, the terminal device displays a pause prompt when recording the focus tracking video is paused. Illustratively, the recording interface shown at c in fig. 9A further includes: pause prompt 910. The widget 908 displays a pause prompt 910.
