[0059] Figure 6 is a block diagram of an electronic device shown in an embodiment of the present disclosure DETAILED DESCRIPTION OF THE EMBODIMENTS

[0060] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0061] In the related art, during the shooting process of electronic devices such as cameras (e.g., single-lens reflex cameras), mobile phones, and tablet computers, based on object detection technology, the shooting subject in the preview image is detected, and the shooting subject is kept in a prominent position by automatically adjusting the focal length or shooting angle, such as keeping the shooting subject always at the center of the screen. The user can also manually select the shooting subject to be tracked.

[0062] Although in the above related art, the shooting subject can be located at the center of the captured image based on technologies such as object detection, this solution is lacking in highlighting the shooting subject and enhancing the visual impact.

[0063] In view of this, an embodiment of the present disclosure provides a shooting method, and its execution subject can be a shooting device. For example, the shooting method can be executed by a terminal device or other electronic devices including an image acquisition component. Among them, the terminal device can be a mobile phone, a camera, a tablet computer, a vehicle-mounted device, a wearable device, a laptop computer, etc. The shooting method of the embodiment of the present disclosure can also be executed in cooperation by the terminal device and the server, or based on the cooperation of multiple terminals or devices; for example, the terminal device can capture and display image frames, and the terminal device can send the image frames to the server, and the server processes the image frames to obtain a processed video; or for another example, a terminal device with a camera function (such as a camera, a video camera, etc.) can capture image frames, a terminal device with a display function (such as a display, a TV, a mobile phone, a tablet, etc.) can preview and display the image frames, and a terminal device with image processing capabilities (such as a mobile phone, a tablet, a laptop computer, etc.) can process the image frames to obtain a video. In some possible implementation manners, the shooting method can be implemented by a processor calling computer-readable instructions stored in a memory.

[0064] It should be noted that the first image frame to the fourth image frame involved in the embodiment of the present disclosure are named for convenience of description of the image frames, and have nothing to do with the importance degree and the acquisition / display order of the image frames, and are not further limitations on the specific implementation manner of the image frames.

[0065] Figure 1 is an example of the shooting method flow shown in the embodiment of the present disclosure Figure 1 , from Figure 1 it can be seen that it includes the following steps:

[0066] S11, in response to detecting an operation of recording a video, capturing multiple image frames, and displaying a first image frame currently previewed among the multiple image frames and a first mark; wherein the first mark corresponds to a first target scene, and the first target scene is determined according to the scene of the first shooting subject in the first image frame; and the first mark is used to identify an area where the first shooting subject corresponds to the first target scene;

[0067] S12: Generate a first video image of the video based on an image of a region where the first mark is located in the first image frame.

[0068] In step S11, the camera captures multiple image frames when detecting the operation of recording a video; wherein the operation of recording a video may be an interactive operation between a user and a physical button on the camera or a virtual button in a display interface on the camera, or a voice command issued by a user, etc., which is not limited in the embodiments of the present disclosure. For example, the multiple image frames are image frames captured by the camera (such as an image acquisition component of a terminal device) within a duration based on the operation of recording a video.

[0069] The disclosed embodiment captures multiple image frames and displays the first image frame currently previewed among the multiple image frames; wherein the first image frame includes a first photographing subject; the photographing device may process the first image frame based on a target detection algorithm, a foreground detection algorithm, etc., to determine the first photographing subject in the first image frame. The disclosed embodiment first photographing subject may be a person, an animal, a moving or immovable object, etc.

[0070] After identifying the first shooting subject in the first image frame, the shooting device of the embodiment of the present disclosure determines the scene of the first shooting subject in the first image frame; wherein the scene includes close-up, close-up, mid-shot, panorama, long shot, etc.; taking the first shooting subject as a person as an example, the close-up refers to the part above the shoulders of the human body, the close-up refers to the part above the chest of the human body, the mid-shot refers to the part above the knees of the human body, the panorama refers to the whole human body, and the long shot includes the whole human body and the surrounding environment.

[0071] In some embodiments, the photographing device automatically analyzes the first photographing subject based on a target detection algorithm, a key point detection algorithm, etc., determines the range information of the first photographing subject in the first image frame, and then uses the range information corresponding to the analyzed range information as the range of the first photographing subject in the first image frame according to the preset correspondence between the range information and the range. For example, if the first photographing subject is a person, the range information in the first image frame is analyzed as the range above the shoulders of the human body, and the corresponding range of the first photographing subject is a close-up; for another example, if the first photographing subject is an animal, the range information in the first image frame is analyzed as the whole body of the animal, and the corresponding range of the first photographing subject is a panoramic view.

[0072] In some embodiments, the photographing device may also determine the scene of the first photographed subject based on the area ratio of the first photographed subject in the first image frame and the corresponding relationship between the preset area ratio and the scene.

[0073] After determining the scene of the first photographed subject, the photographing device according to an embodiment of the present disclosure determines a first target scene based on the scene of the photographed subject; in some embodiments, the first target scene corresponding to the scene of the first photographed subject in the first image frame may be determined based on the corresponding relationship between the preset scene and the first target scene; wherein, in the corresponding relationship between the preset scene and the first target scene, the viewing range corresponding to the first target scene may be smaller than the viewing range corresponding to the mapped scene. For example, if the scene of the first photographed subject is a panoramic view, the corresponding first target scene may be a medium shot, a close-up shot, or a close-up, so as to present an effect of zooming in (focusing on the local part) based on the viewing image corresponding to the first target scene; in addition, the viewing range corresponding to the first target scene may also be larger than the viewing range corresponding to the mapped scene. For example, if the scene of the first photographed subject is a close-up shot, the corresponding first target scene may be a medium shot, a close-up shot, or a panoramic view, so as to present an effect of zooming out (focusing on the whole) based on the viewing image corresponding to the first target scene, etc.

[0074] After determining the first target scene according to an embodiment of the present disclosure, a first mark is displayed on the first image frame; wherein, the first mark corresponds to the first target scene, and the first mark is used to identify the area where the first photographed subject corresponds to the first target scene. For example, if the first target scene is a close-up shot, the corresponding viewing range is above the shoulders of the human body, so the first mark identifies the area above the shoulders of the first photographed subject; if the first target scene is a close-up shot, the corresponding viewing range is above the chest of the human body, so the first mark identifies the area above the chest of the first photographed subject, etc. The shape of the first mark according to an embodiment of the present disclosure may be a square, a rectangle, a circle, or other polygons, and the line of the first mark may be a solid line, a dotted line, etc. The present disclosure does not limit this.

[0075] The first mark according to an embodiment of the present disclosure can highlight the first photographed subject in the first image frame, and the presence of the first mark does not affect the content of the first image frame. For example, the interface for displaying the image frame according to an embodiment of the present disclosure includes a layer for displaying the image frame (displaying the previewed first image frame), and the first mark may be displayed by overlaying a mask layer on the layer for displaying the first image frame; or, the interface for displaying the image frame includes multiple layers, and the first mark may be displayed on the layer above the layer where the first image frame is located, so as to bring an overall display effect to the user.

[0076] It should be noted that while the shooting device in the embodiments of the present disclosure displays the first image frame, it also displays the area corresponding to the first target scene of the first shooting subject, so that the first mark moves following the movement of the first shooting subject.

[0077] In step S12, the shooting device generates the first video image of the video based on the image of the area where the first mark is located in the first image frame. Exemplarily, the shooting device crops the first image frame according to the area where the first mark is located to obtain the image of the area where the first mark is located, and thus uses the image of the area where the first mark is located as the first video image of the video.

[0078] Another exemplarily, the shooting device can perform processing such as stretching, tiling, and interpolation on the image of the area where the first mark is located to obtain the first video image of the video, etc., so that the size of the first video image adapts to the display size of the display component (such as a display screen).

[0079] Figure 2 is a comparative example diagram before and after shooting processing shown in the embodiments of the present disclosure. Figure 2 In the figure, L1 identifies the first image frame, L2 identifies the first video image generated by using the shooting method provided by the embodiments of the present disclosure, and a1 identifies the first mark; the shooting range of the first target scene is smaller than the shooting range of the first shooting subject in the first image frame. It can be seen that the first shooting subject in the first video image identified by L2 is more prominent and has a stronger visual impact.

[0080] It can be understood that the embodiments of the present disclosure respond to the detected operation of recording a video, capture multiple image frames, display the currently previewed first image frame and the first mark in the multiple image frames, and generate the first video image of the video based on the image of the area corresponding to the first shooting subject corresponding to the first target scene identified by the first mark in the first image frame; since the first mark in the embodiments of the present disclosure corresponds to the first target scene, and the first target scene is determined according to the scene of the first shooting subject in the first image frame, it thus realizes guiding the generation of the first video image based on the area associated with the first target scene (i.e., the area where the first mark is located), presenting, for example, magnifying the first shooting subject to highlight the first shooting subject, or presenting a larger view including the first shooting subject to show a more content-rich picture, making the dynamic adjustment of the shooting picture ratio more reasonable, helping the user to shoot a more professional and natural high-quality video, and meeting the user's needs for video shooting.

[0081] In some embodiments, the first image frame further includes a second shooting subject; the method further includes:

[0082] Display a second marker; wherein, the second marker corresponds to a second target scene, and the second target scene is determined according to the scene of the second shooting subject in the first image frame; the second marker is used to identify the area where the second shooting subject corresponds to the second target scene; the visual effect of the second marker is different from that of the first marker to highlight the image in the area where the first marker is located.

[0083] In the embodiments of the present disclosure, the first image frame currently previewed includes a first shooting subject and a second shooting subject, wherein the second shooting subject can be one object or multiple objects.

[0084] While displaying the first image frame and the first marker currently previewed in multiple image frames in the embodiments of the present disclosure, a second marker is displayed, such as Figure 2 the rectangular frame other than the first marker identified by a1 in the figure; wherein, the second marker corresponds to a second target scene, and the second target scene is determined according to the scene of the second shooting subject in the first image frame. The manner in which the embodiments of the present disclosure determine the scene of the second shooting subject in the first image frame is similar to the foregoing manner of determining the scene of the first shooting subject in the first image frame; the manner in which the embodiments of the present disclosure determine the second target scene according to the scene of the second shooting subject in the first image frame is similar to the foregoing manner of determining the first target scene according to the scene of the first shooting subject in the first image frame, which will not be elaborated here.

[0085] The second marker displayed in the embodiments of the present disclosure is used to identify the area where the second shooting subject corresponds to the second target scene; wherein, the visual effect of the second marker is different from that of the first marker, for example, their shapes, sizes, colors, etc. are different, and the first marker is more prominent visually than the second marker. Exemplarily, the size of the first marker is larger than that of the second marker; the line color of the first marker is yellow, and the line color of the second marker is gray, etc., so that the image in the area where the first marker is located can be highlighted based on the displayed first marker and second marker.

[0086] It can be understood that in the case where the first image frame includes multiple shooting subjects in the embodiments of the present disclosure, based on the different markers corresponding to the first shooting subject and other shooting subjects (i.e., the second shooting subject), the image in the area where the first marker including the first shooting subject is located is highlighted, facilitating the user to intuitively learn the current focus image. In addition, in the case where the user intends to switch the subject, the focus object can be switched conveniently and quickly by clicking on the area where the second marker is located.

[0087] In some embodiments, the imaging range of the first shooting subject under the first target scene is smaller than that under the scene, and the frame occupied by the first shooting subject under the first target scene is larger than that under the scene.

[0088] In the embodiments of the present disclosure, the imaging range of the first shooting subject at the first target scene is smaller than that at the scene, that is, compared with the scene of the first shooting subject in the first image frame, the view-finding range corresponding to the first target scene in the embodiments of the present disclosure is smaller; and the frame occupied by the first shooting subject at the first target scene in the embodiments of the present disclosure is larger than that at the scene, so that the local part of the first shooting subject within the view-finding range corresponding to the first target scene is visually highlighted and magnified.

[0089] Exemplarily, as Figure 3 shown, Figure 3 is an example of the shooting method flow shown in the embodiments of the present disclosure Figure 2 , from Figure 3 it can be seen that the following steps are included:

[0116] It can be understood that the imaging range of the first shooting subject in the first target scene in the embodiment of the present disclosure is smaller than that in the scene, and the frame occupied by the first shooting subject in the first target scene is larger than that in the scene. Therefore, the first image frame of the video is generated based on the image within the first mark corresponding to the first target scene, visually pulling the first shooting subject closer, and it is possible to highlight the first shooting subject and improve the visual impact on the user without adjusting the focal length.

[0117] In some embodiments, the captured multiple image frames further include a second image frame, and the second image frame includes a third shooting subject; the method further includes:

[0118] In response to detecting a subject switching instruction, the currently previewed second image frame and a third mark are displayed; wherein the third mark corresponds to a third target scene, and the third target scene is determined according to the scene of the third shooting subject in the second image frame; the third mark is used to identify the area where the third shooting subject corresponds to the third target scene;

[0119] Based on the image in the area where the third mark is located in the second image frame, a second video image of the video is generated.

[0120] In an embodiment of the present disclosure, the captured multiple image frames further include a second image frame, wherein the second image frame includes at least a third shooting subject, and the third shooting subject is not limited to a person, an animal, a moving or immovable item, etc.

[0121] In the shooting device according to the embodiments of the present disclosure, when a subject switching instruction is detected, the second image frame currently being previewed and a third marker for identifying the area where the third shooting subject corresponds to the third target scene are displayed; wherein, the third marker corresponds to the third target scene, and the third target scene is determined according to the scene of the third shooting subject in the second image frame. The method for determining the scene of the third shooting subject in the second image frame in the embodiments of the present disclosure is similar to the method for determining the scene of the first shooting subject in the first image frame; the method for determining the third target scene according to the scene of the third shooting subject in the second image frame in the embodiments of the present disclosure is similar to the method for determining the first target scene according to the scene of the first shooting subject in the first image frame, which will not be elaborated here.

[0122] In the embodiments of the present disclosure, detecting the subject switching instruction may be detecting a touch instruction, a voice instruction, a gesture instruction, etc. issued by the user. In addition, the shooting device may also identify the subject switching instruction automatically; for example, when there are multiple shooting subjects in the second image frame, the shooting device in the embodiments of the present disclosure determines the area ratio of each shooting subject in the second image frame, and in response to the change of the shooting subject with the largest area ratio, detects the subject switching instruction, and uses the shooting subject with the largest area ratio as the third shooting subject after switching the subject.

[0123] After determining the third marker for identifying the area where the third shooting subject corresponds to the third target scene in the embodiments of the present disclosure, a second video image of the video is generated based on the image in the area where the third marker is located in the second image frame.

[0124] It can be understood that, based on the detected subject switching instruction, the embodiments of the present disclosure can switch to the third shooting subject intended by the user or automatically identify and present the third shooting subject, and display the third marker based on the third target scene corresponding to the third shooting subject to generate a second video image, so as to meet the requirement of generating videos by switching different shooting subjects.

[0125] In some embodiments, the first shooting subject is further included in the second image frame; the method further includes:

[0126] In response to detecting the subject switching instruction, the display of the first marker is cancelled.

[0127] In the embodiments of the present disclosure, when the first shooting subject and the second shooting subject are included in the second image frame, in response to detecting the subject switching instruction, the second image frame currently being previewed and the second marker are displayed, and the display of the first marker is cancelled; and then a second video image of the video is generated based on the image in the area where the second marker is located in the second image frame.

[0128] It can be understood that when the second image frame also includes the first shooting subject, in response to detecting a subject switching instruction, that is, switching from the first shooting subject to the second shooting subject, the first mark corresponding to the first shooting subject is cancelled and only the second mark corresponding to the second shooting subject is displayed, which can reduce the visual interference caused by the display of the first mark to the user and improve the purposefulness of responding to the subject switching instruction.

[0129] In some embodiments, the captured multiple image frames further include a third image frame, and the third image frame includes the first shooting subject; the method further includes:

[0130] In response to detecting a scene switching instruction, display the currently previewed third image frame and a fourth mark; wherein, the fourth mark corresponds to the scene indicated by the scene switching instruction; the fourth mark is used to identify the area where the first shooting subject is located corresponding to the scene indicated by the scene switching instruction;

[0131] Generate a third video image of the video based on the image in the area where the fourth mark is located in the third image frame.

[0132] In the embodiments of the present disclosure, the captured multiple image frames further include a third image frame, wherein the third image frame at least includes the first shooting subject.

[0133] When the shooting device in the embodiments of the present disclosure detects a scene switching instruction, it displays the currently previewed third image frame and a fourth mark for identifying the scene corresponding to the first shooting subject indicated by the scene switching instruction; wherein, detecting the scene switching instruction in the embodiments of the present disclosure can be a touch instruction, a voice instruction, a gesture instruction, etc. issued by the detected user. For example, the display interface includes a plurality of virtual buttons, and each virtual button corresponds to a scene. When detecting a touch instruction of the user on a certain virtual button, the scene corresponding to the virtual button to which the touch instruction acts is determined as the scene indicated by the scene switching instruction.

[0134] In addition, the shooting device can also identify the scene switching instruction in an automatic manner; for example, when the area ratio of the first shooting subject in the third image frame is greater than a first preset ratio threshold, a scene switching instruction is detected, and the first preset scene is determined as the scene indicated by the scene switching instruction; or, when the area ratio of the first shooting subject in the third image frame is less than a second preset ratio threshold, a scene switching instruction is detected, and the second preset scene is determined as the scene indicated by the scene switching instruction.

[0135] After determining the fourth mark for identifying the scene corresponding to the first shooting subject indicated by the scene switching instruction in the embodiments of the present disclosure, a third video image of the video is generated based on the image in the area where the fourth mark is located in the third image frame.

[0136] It can be understood that the embodiments of the present disclosure can switch to the scene in which the first shooting subject is presented according to the detected scene switching instruction, or automatically identify the scene of the first shooting subject that is preferably presented, and generate a third video image based on the area where the scene indicated by the scene switching instruction corresponding to the first shooting subject is located, so as to meet the requirement of generating a video by switching different shooting scenes.

[0137] In some embodiments, the method further includes:

[0138] In response to detecting a shooting subject in the first image frame of the current preview, when the orientation of the shooting subject meets the preset orientation condition and / or the area ratio of the shooting subject is greater than the preset area ratio threshold, the shooting subject is determined as the first shooting subject in the first image frame of the current preview.

[0139] In the embodiments of the present disclosure, the shooting device uses a target detection algorithm to detect the shooting subject in the first image frame, and determines the orientation of the shooting when the shooting is detected in the first image frame; wherein, the orientation of the shooting subject is such as the face orientation, body orientation, etc.; for example, the face orientation recognition can be realized by using a Learning Vector Quantization (LVQ) neural network, a model based on a self-attention mechanism (Vision Transformer, VT), etc.

[0140] In addition, the shooting device determines the area ratio of the shooting subject in the first image frame; for example, the ratio between the size of the shooting subject and the size of the first image frame can be determined as the area ratio, or the ratio between the number of pixel points included in the shooting subject and the number of pixel points included in the first image frame can be determined as the area ratio.

[0141] In the embodiments of the present disclosure, if the orientation of the shooting subject is the preset direction (such as the face facing the shooting device) or is within the preset angle range with the normal line of the photosensitive surface of the image sensor, it is determined that the orientation of the shooting subject meets the preset orientation condition, so as to determine the shooting subject with the orientation meeting the preset orientation condition and / or the area ratio greater than the preset area ratio threshold as the first shooting subject in the first image frame.

[0142] It can be understood that the first shooting subject in the embodiments of the present disclosure is the shooting subject facing the direction that meets the preset direction condition and / or occupies a larger proportion in the picture, that is, the first shooting subject is more likely to be the object that the user pays more attention to. Therefore, in the embodiments of the present disclosure, the shooting subject whose direction meets the preset direction condition and / or the area proportion is greater than the preset area proportion threshold is determined as the first shooting subject in the first image frame, and then the first video frame is generated based on the image of the area corresponding to the first shooting subject identified by the first mark in the first target scene, so that the first video frame better meets the user's attention expectation, thereby improving the intelligence of video generation and the user's shooting experience.

[0143] In some embodiments, generating the first video image of the video based on the image of the area where the first mark is located in the first image frame includes:

[0144] When the first shooting subject does not leave the shooting area of the first image frame in the current preview, the first image frame including the first shooting subject is cropped based on the first mark to generate the first video image.

[0145] In the embodiments of the present disclosure, the first shooting subject in the captured image frame may move out of the shooting area. In this regard, when the first shooting subject does not leave the shooting area of the first image frame in the current preview, at this time, the first mark always identifies the area corresponding to the first target scene of the first shooting subject, so that the first image frame including the first shooting subject is cropped based on the first mark to generate the first video image, which can improve the accuracy and rationality of generating the first video image.

[0146] In some embodiments, the plurality of captured image frames further include a fourth image frame, and the fourth image frame includes the first shooting subject; the method further includes:

[0147] When the first shooting subject leaves the shooting area of the fourth image frame in the current preview, the fourth video image of the video is generated based on the image in the fourth image frame.

[0148] In the embodiments of the present disclosure, among the captured multiple image frames, there is also a fourth image frame, and the first shooting subject is included in the fourth image frame. In the embodiments of the present disclosure, when the first shooting subject leaves the shooting area of the currently previewed fourth image frame, that is, when there is no area in the fourth image frame corresponding to the first mark where the first shooting subject is located, a fourth video image of the video is generated based on the image in the fourth image frame. For example, when the shooting device determines that the first shooting subject has left the shooting area of the currently previewed fourth image frame, it directly uses the image in the second image frame as the fourth video image; or, it crops the fourth image frame within a preset range (such as the central 1 / 3 area of the fourth image frame), and obtains the fourth video image based on the cropped image. This enables the fourth video frame to include more environmental information when the first shooting subject leaves the shooting area, improving the visual experience of the fourth video frame.

[0149] In addition, during the process of shooting a video, if the first shooting subject leaves the shooting area, the shooting range can be gradually expanded to obtain a video frame with an expanded shooting range, making the visual transition of the video imaging smoother and the visual effect better.

[0150] In some embodiments, the generating the fourth video image of the video based on the image in the fourth image frame when the first shooting subject leaves the shooting area of the currently previewed fourth image frame includes:

[0151] When the duration for which the first shooting subject leaves the shooting area of the currently previewed fourth image frame is greater than a preset duration threshold, a fourth video image of the video is generated based on the image in the fourth image frame.

[0152] In the embodiments of the present disclosure, the shooting device determines the duration for which the first shooting subject leaves the shooting area, and when the duration for which the first shooting subject leaves the shooting area is greater than a preset duration threshold, a fourth video image of the video is generated based on the image in the fourth image frame; when the duration for which the first shooting subject leaves the shooting area is less than or equal to the preset duration threshold, the fourth video image of the video is continuously generated based on the image in the area where the first mark including the first shooting subject is located in the fourth image frame.

[0153] It can be understood that since there may be a situation where the shooting subject occasionally leaves the shooting area, or the shooting subject is occasionally blocked, resulting in the shooting subject not being detected and misjudged as leaving the shooting area. In this regard, in the embodiments of the present disclosure, when the duration for which the first shooting subject leaves the shooting area is greater than a preset duration threshold, the shooting device generates a fourth video image of the video based on the image in the fourth image frame, which can reduce problems such as visual fatigue caused by frequently changing the shooting range due to the occasional failure to detect the first shooting subject.
