[0071] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0072] At present, most mobile phones, tablets, cameras and other terminals with shooting functions only have one display screen to display the preview content during the shooting process. During the video recording process, a real-time focus indicator is added to the display screen to display the current focus status. The real-time focus indicator can be a focus frame, focus point or other forms of indicators. The indicator and the preview data stream of the video recording are displayed in one window. The indicator may distract the user's attention, and the relevant data information and pictures in the indicator cannot provide a complete reference for the user.

[0073] Reference Figure 1 , Figure 1 is a flow chart of a video recording method according to an exemplary embodiment. Figure 1 As shown, the video recording method is used in a terminal and includes the following steps.

[0074] In step S101, in response to a video recording operation, a first window is displayed on a video recording interface, where the first window is used to display preview content during the video recording process.

[0075] For example, the video recording operation may be an operation such as a user clicking or sliding a video recording function on a display screen of a terminal. Based on the video recording operation, a first window is displayed on a video recording interface of the display screen of the terminal, and a preview content during the video recording process may be displayed through the first window, wherein the preview content includes a video data stream based on a time series.

[0076] In step S102, in response to a triggering operation on the target auxiliary function, a second window is displayed on the video recording interface, and the second window is used to display information corresponding to the target auxiliary function, and the target auxiliary function is used to display or control data during the video recording process.

[0077] For example, a selection control may be provided in the video recording interface, and the user may select a target auxiliary function by clicking, sliding, voice control, or other control methods according to the multiple auxiliary functions listed in the selection control, thereby triggering the target auxiliary function. Based on the triggering operation of the target auxiliary function, a second window for displaying information corresponding to the target auxiliary function may be displayed in the video recording interface, wherein the arrangement of the first window and the second window may include parallel display, floating display of the second window on the first window, and the like.

[0078] For example, the target assist function can be used to display data during video recording, such as displaying recording parameters during video recording, previewing the video data stream after adjusting the shooting parameters, displaying the video data stream after adding auxiliary marks, displaying adjustment controls for adjusting shooting parameters, etc. The target assist function can also be used to control data during video recording, such as adjusting shooting parameters using adjustment controls, selecting a designated area to be enlarged according to user operations, adding or selecting marks for auxiliary shooting according to user operations, etc. Among them, shooting parameters can be, for example, brightness data, color channel data, blur data, focus data, highlight or shadow data, etc.

[0079] The present disclosure is based on a video recording operation, and displays a first window in the video recording interface for displaying preview content during the video recording process, and based on a triggering operation of a target auxiliary function, displays a second window in the video recording interface for displaying information corresponding to the target auxiliary function. In this way, the preview content during the video recording process and the information corresponding to the target auxiliary function are displayed separately through the first window and the second window, and based on the triggering operation of the target auxiliary function, the information corresponding to the target auxiliary function is displayed in the second window instead of displaying multiple indicators, which takes into account the actual needs of users and avoids the problem of a cluttered display interface.

[0080] As an optional embodiment, in response to a triggering operation of the target auxiliary function, a second window is displayed on the video recording interface, including:

[0081] In response to a triggering operation on a target auxiliary function, obtaining a video data stream during a video recording process;

[0082] Processing the video data stream according to the target auxiliary function to obtain display data;

[0083] A second window including display data is displayed on the video recording interface.

[0084] For example, the video data stream during the video recording process can be obtained from the image sensor or image cache through the camera software interface (API) or the image processing library. When the terminal receives a trigger operation for the target auxiliary function, the video data stream during the video recording process can be processed using the processing flow corresponding to the target auxiliary function. It can be understood that different auxiliary functions correspond to different processing flows. After the processing is completed, the display data for display on the second window is obtained, and the second window including the display data is displayed on the video recording interface to provide a reference for the user's video recording process.

[0085] As an optional embodiment, the video data stream is processed according to the target auxiliary function to obtain display data, including:

[0086] In response to the area selection operation in the first window, determining a designated area of ​​a target image in the video data stream, where the target image is any frame image in the video data stream;

[0087] determining a focus area in a specified area;

[0088] The designated area and the focus area are processed according to the target auxiliary function to obtain display data.

[0089] For example, the area selection operation is, for example, a click, a slide, or the like operation mode, and the user can determine the designated area in the target image in the video data stream based on the area selection operation in the first window. It can be understood that the position point on the image data when the area selection operation is triggered can be a focus. The designated area can be an area within the first range that triggers the focus, such as a circular area centered on the focus and 20 pixels away from the focus range. Or the designated area can be within a preset shape range centered on the focus, such as a rectangular area of ​​20 pixels × 40 pixels centered on the focus. Generally, the shape of the designated area is consistent with the shape of the second window. The focus area can be determined based on the focus subject near the focus. When the area selection operation is triggered, the focus subject in the designated area can be identified by an image recognition algorithm, such as computer vision technology or a deep learning model, and the corresponding focus area can be selected. Or the focus area can also be an area within the second range of the focus, and the first range is larger than the second range.

[0090] As an optional embodiment, the target auxiliary function is a focus area magnification function, and the designated area and the focus area are processed according to the target auxiliary function to obtain display data, including:

[0091] A focus area is enlarged to obtain an enlarged focus area;

[0092] The magnified focus area and the specified area are synthesized to obtain display data.

[0093] For example, when the target auxiliary function is a focus area magnification function, an image interpolation algorithm, such as bilinear interpolation or bicubic interpolation, can be used to increase the number of pixels and image details in the focus area to achieve magnification of the focus area. The enlarged focus area can be synthesized with the designated area through image synthesis technology to obtain an image of the designated area after the focus is enlarged, and the image of the designated area can be displayed in the second window. In order to improve the performance and user experience of the focus area magnification function, technical means such as parallel computing, hardware acceleration and optimization algorithms can also be considered to improve the speed and quality of image processing and reduce delay time.

[0094] For example, when the target auxiliary function is the focus area magnification function, a second window is displayed in the video recording interface. When the user performs a focus operation, by acquiring the video data stream and using an algorithm to analyze the focus subject of the target image in the video data stream, the center position of the focus subject or the area selected by the user can be determined as the focus area to be magnified. After the focus area is magnified, the original designated area and the focus area are synthesized and displayed in the second window. This provides more intuitive visual feedback to the user. The user can more accurately determine the focus area and check the clarity of the focus area in real time through the magnified focus area in the second window.

[0095] As an optional embodiment, the target auxiliary function is a focus marking function, and the designated area and the focus area are processed according to the target auxiliary function to obtain display data, including:

[0096] Generate a focus mark according to the focus subject in the focus area;

[0097] The focus mark is combined with the specified area to obtain display data.

[0098] For example, a focus mark can be added to the video recording interface so that the user can align and adjust the focus position more accurately. The focus mark can be a grid line, a focus reference line, an auxiliary pattern, or other forms of marks. Here, when the target auxiliary function is a focus mark function, a second window is displayed on the video recording interface. When the user performs a focus operation, by acquiring a video data stream, a preprocessing operation is performed on the target image in the video data stream, such as image enhancement, denoising, and color correction, etc., the image quality and the accuracy of identifying the focus subject can be improved. Then, the focus subject analysis of the target image in the video data stream is performed using an algorithm to determine the position of the focus subject, and according to the focus subject identified in the focus area and the original designated area, an image of the designated area with a focus mark can be obtained by image synthesis or image superposition and displayed in the second window. In this way, the focus mark is superimposed on the focus subject in the designated area, and the user can align and adjust the focus position faster through the focus mark.

[0099] For example, Figure 6 As shown, when the user clicks on the designated area 500 including the focus subject in the first window 400, for the focus area magnification function, the focus area in the designated area 500 of the image displayed in the first window 400 is magnified, and the enlarged focus area is synthesized with the designated area and displayed in the second window 301; for the focus mark function, the preview content during the video recording process is displayed in the first window 400, and the blur effect can be displayed, but the focus mark, focus frame, etc. are not displayed, and the currently focused focus subject can be displayed in the second window 301, the focus mark 303 can be displayed in the second window 301, or the second window 301 can also display information such as the blurred object and the degree of blur.

[0100] As an optional embodiment, the target auxiliary function is a data display function, and the video data stream is processed according to the target auxiliary function to obtain display data, including:

[0101] Acquire shooting parameters of a target image in a video data stream, where the target image is any frame image in the video data stream, and the shooting parameters include brightness data and / or color channel data;

[0102] Processing the shooting parameters to obtain a histogram;

[0103] Use a histogram as display data.

[0104] For example, when the target auxiliary function is a data display function, the histogram obtained by processing the brightness data and / or color channel data of the target image in the video data stream is displayed, so that the user can intuitively view the brightness data and / or color channel data during the video recording process according to the histogram. Figure 2 As shown, the horizontal axis of the histogram represents the brightness level, and the vertical axis represents the number of pixels occupied by the color. The number of pixels at each brightness level of the image is graphically represented to show the distribution of pixels in the image. Specifically, the histogram shows details in the shadows (shown in the left part of the histogram), midtones (shown in the middle), and highlights (shown in the right part). The histogram can help users determine whether an image has enough details for good correction. It can be understood that the details of low-key images are concentrated in the shadows, the details of high-key images are concentrated in the highlights, and the details of average-key images are concentrated in the midtones. Images with a full tonal range have a large number of pixels in all areas.

[0105] For example, different styles of histogram displays, such as linear graphs, bar graphs, or color distribution graphs, may be provided to meet the personalized needs and preferences of users.

[0106] As an optional embodiment, the target auxiliary function is a target tracking function, and the video data stream is processed according to the target auxiliary function to obtain display data, including:

[0107] Determine an object of interest of a target image in a video data stream, where the target image is any frame image in the video data stream;

[0108] The target parameters of the target of interest are used as display data.

[0109] For example, when the target assist function is a target tracking function, by acquiring the video data stream, computer vision technology, such as target detection and tracking algorithms, can be used to identify and track the target of interest in the target image in the video data stream to determine the position, motion trajectory and other features of the target of interest. Then, by synthesizing the information window displaying the relevant information of the target of interest with the target image and displaying it in the second window, intelligent mirror display can be achieved. During the video recording process, the operation of determining the target of interest can be continuously repeated, and the display content in the second window can be updated by continuously acquiring, analyzing and processing the latest image data to ensure that the display content and position are consistent with the target of interest.

[0110] For example, see Figure 3 When following the target for shooting, the target parameters of the target of interest can be displayed in the second window 301 through the target tracking function. The target parameters can be, for example, the distance, speed, direction, camera movement speed, camera direction, camera effect, etc. of the target of interest. A bounding box 302 for selecting the target of interest can also be displayed on the video recording interface. The bounding box 302 is used to indicate the current target of interest. The size of this bounding box 302 can be adjusted by the user. During the recording process, the user can specify a new target of interest, and can also re-identify the new target of interest according to the image recognition algorithm when the picture changes. When determining the target of interest in the target image in the video data stream, the target detection algorithm can be used to identify and track the target of interest in the target image to determine the position, motion trajectory and other characteristics of the target, etc., which can be set according to actual needs.

[0111] In addition, an interactive interface can be provided for users, and target parameters for display can be selected in the interactive interface through interactive elements such as menus, sliders, and buttons, so that users can customize and adjust the content and style displayed in the interactive interface.

[0112] As an optional embodiment, the target auxiliary function is a focus conversion function, and the video data stream is processed according to the target auxiliary function to obtain display data, including:

[0113] Determining a current focused subject in a video data stream;

[0114] When the object of interest in the video data stream is converted from the current focus subject to the target focus subject, the focus is moved from the position of the current focus subject to the position of the target focus subject;

[0115] The focus area corresponding to the target focus subject is used as display data.

[0116] For example, during video recording, the focus position can be automatically moved through the focus conversion function. Here, the target of interest can be identified based on the image recognition algorithm, for example, an object or animal in motion, a person in a speaking state, etc. can be used as a target of interest. In the case where the person's speaking state switches, or one object is still and another object starts to move, the focus can be moved from the position of the current focus subject to the position of the target focus subject to realize the focus conversion function. After the focus is moved, the focus area corresponding to the focus position can be used as display data. In this process, the focus subject in the second window display screen is switched from the current focus subject to the target focus subject.

[0117] As an optional embodiment, the target auxiliary function is a focus compensation function, and a first adjustment control for adjusting focus data is displayed in the second window. The method further includes:

[0118] Get the video data stream during video recording;

[0119] determining focus compensation data in response to an adjustment operation on the first adjustment control;

[0120] The focus data of the video data stream is adjusted according to the focus compensation data, and the video data stream after the focus data is adjusted is displayed on the video recording interface.

[0121] For example, when the target auxiliary function is a focus compensation function, a first adjustment control for adjusting focus data is displayed in the second window, and the user can adjust the focus data in the video data stream by performing an adjustment operation on the first adjustment control.

[0122] For example, the focus data can be obtained by a focus sensor of the camera, phase focus technology or other focus measurement methods. The interactive element of the first adjustment control can be, for example, a sliding bar, plus or minus buttons or other interactive elements, etc. The focus compensation data required by the user to compensate the focus data can be determined by sliding the first adjustment control or clicking the corresponding button, and the focus compensation data can be increased or decreased by using the focus data to determine the adjusted focus data.

[0123] In addition, in order to improve the performance and stability of the focus compensation adjustment function, appropriate focus sensors, optimization algorithms and feedback mechanisms can be used to ensure that the user's adjusted diagonal data can be accurately applied to the actual focusing process and obtain a better focusing effect.

[0124] For example, when the target auxiliary function is a focus compensation function, the user can be provided with interactive controls for focus compensation adjustment in the second window, such as a slider, plus or minus buttons, etc., so that the user can intuitively adjust the focus compensation parameters. After the user performs an adjustment operation on the interactive control, the focus data is obtained through a focus sensor, phase focus technology or other focus measurement methods, and based on the focus compensation algorithm, the focus position can be fine-tuned according to the focus compensation data adjusted by the user to achieve an over-focus or slightly under-focus effect, so as to apply the focus compensation data adjusted by the user to the actual focusing process. Specifically, in response to the user's sliding or clicking operation on the first adjustment control, the focus position is adjusted accordingly according to the focus compensation data set by the user, and the picture after the focus compensation adjustment can be displayed in real time in the video recording interface or the second window, so that the user can intuitively observe and confirm the adjusted focus result.

[0125] As an optional embodiment, the method further includes:

[0126] In response to the call operation of the target focus data in the historical parameter record, the focus data of the video data stream is adjusted to the target focus data, and the video data stream with adjusted focus data is displayed on the video recording interface. The historical parameter record includes multiple focus data saved during the historical recording of the video.

[0127] For example, in order to facilitate users to adjust focus compensation in different scenes, a function of saving and restoring diagonal data can be provided. In response to the operation of saving the adjusted focus data, the adjusted focus data is saved in the historical parameter record, and in response to the operation of calling the target focus data in the historical parameter record, the focus data of the video data stream is adjusted to the target focus data. In this way, users can easily switch between different shooting scenes and automatically restore the previously set focus data.

[0128] As an optional embodiment, the target auxiliary function is a blur data adjustment function, and a second adjustment control for adjusting the blur data is displayed in the second window. The method further includes:

[0129] Get the video data stream during video recording;

[0130] In response to an adjustment operation on the second adjustment control, determining target blurring data;

[0131] The video data stream adjusted to the target blurred data is displayed on the video recording interface.

[0132] For example, the target assist function can also adjust the blurred data. A second adjustment control for adjusting the blurred data is displayed in the second window. The user can adjust the blurred data in the video data stream by performing an adjustment operation on the second adjustment control.

[0133] By way of example, the interactive elements of the second adjustment control may be, for example, a sliding bar, plus or minus buttons, or other interactive elements, etc. The target blur data adjusted by the user may be determined by the user sliding the second adjustment control or clicking a corresponding button, and the target blur data may be applied to the video data stream, so that the blur data of the video data stream is adjusted to the target blur data and displayed in the second window.

[0134] As an optional embodiment, a display area of ​​the first window is larger than a display area of ​​the second window.

[0135] For example, in the video recording interface, the first window is used to display the preview content during the video recording process, and the second window is used to display the information corresponding to the target auxiliary function. In order to ensure that the user's attention is more focused on the preview content during the video recording process, the display area of ​​the first window is set to be larger than the display area of ​​the second window.

[0136] As an optional embodiment, displaying a second window on the video recording interface includes:

[0137] In the video recording interface, the second window is floated on the first window for display.

[0138] For example, see Figure 4 and Figure 5 In the video recording interface, the second window 301 can be Figure 4 The floating mode shown is displayed on the first window 400, and can also be displayed in Figure 5 The parallel arrangement shown is displayed in parallel with the first window 400 in the video recording interface.

[0139] As an optional embodiment, the method further includes:

[0140] In response to the drag operation on the second window, the second window is moved to a target position corresponding to the drag operation.

[0141] For example, the second window may be moved to a target position corresponding to the dragging operation by the user dragging the second window on the terminal screen. The dragging operation may be, for example, long pressing the second window and then sliding it to the target position.
