[0036] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0037] The terms "first," "second," and the like in the specification of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. Furthermore, the term "and / or" in this specification indicates at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0038] The following describes in detail the shooting method, shooting device and electronic device provided in the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0039] In some embodiments of the present application, as shown in FIG1 , a shooting method is proposed, which is performed by an electronic device, the electronic device including a front camera and a rear camera, and the shooting method includes:

[0040] Step 102: Control the front camera to capture a first image.

[0041] In some embodiments of the present application, the front camera may capture images periodically, such as once every 3 seconds, or once every 5 seconds, or once every 1 second. The value may be determined according to the setting requirements and will not be described in detail here.

[0042] Step 104 : setting the first camera movement trajectory corresponding to the first image as the camera movement trajectory corresponding to the first camera in the rear camera.

[0043] In some embodiments of the present application, the correspondence between the gesture corresponding to each image and each camera movement trajectory is pre-set. Then, when the gesture corresponding to the first image is acquired, the gesture corresponding to the first image can be used to search in the correspondence to determine the first camera movement trajectory.

[0044] In some embodiments of the present application, the first image includes one of a gesture associated with the first camera movement trajectory, text associated with the first camera movement trajectory, and an object image associated with the first camera movement trajectory.

[0045] In some embodiments of the present application, the first camera movement trajectory is set to the camera movement trajectory corresponding to the first camera in the rear camera. It can be understood that the first camera movement trajectory is associated with the first camera so as to display the first shooting preview screen corresponding to the first camera based on the first camera movement trajectory.

[0046] Step 106: Display a first shooting preview image corresponding to the first camera based on the first camera movement trajectory.

[0047] In the embodiment of the present application, the front-facing camera is controlled to capture images to detect user operations, and then a camera movement trajectory is bound to the first camera based on the captured first image, so that the electronic device can display a first shooting preview image corresponding to the first camera based on the first camera movement trajectory. During this process, the user does not need to operate the touch screen, and even if the touch screen is malfunctioning, the camera can still be bound to the desired camera movement trajectory.

[0048] In this embodiment, by binding the first camera to the first camera movement trajectory, and then displaying the first shooting preview interface according to the first camera movement trajectory, the user does not need to manually move the camera during the shooting process, and the object to be shot can always be stably displayed in the shooting preview interface, so that the object to be shot can be shot with a stable camera movement trajectory, thereby reducing the difficulty of shooting.

[0049] Among them, camera movement refers to shooting methods such as "push", "pull", "turn", "move", "penetrate", "follow" and "shake". In the embodiment of the present application, it can be understood as controlling the camera to move or cropping and scaling the captured image.

[0050] In some embodiments of the present application, the camera movement trajectory is essentially a plurality of state streams connected in sequence, wherein any state in the plurality of state streams connected in sequence has posture information of an electronic device and position information of a corresponding shooting selection area.

[0051] In some embodiments of the present application, the first camera movement trajectory may be recorded by an electronic device, or may be a camera movement trajectory recorded by other electronic devices and then stored in the electronic device.

[0052] Specifically, displaying the first shooting preview screen corresponding to the first camera based on the first camera movement trajectory specifically includes: obtaining the first camera movement trajectory, the first camera movement trajectory including the first posture information of the electronic device and the first position information of the follow-up object in the shooting preview interface; when shooting according to the first camera movement trajectory, obtaining the second posture information of the electronic device and the second position information of the follow-up object in the shooting preview interface; processing the shooting screen based on the first posture information, the second posture information, the first position information and the second position information of the follow-up object in the shooting preview interface, thereby realizing camera movement.

[0053] During this process, the shooting picture is processed in combination with the current second posture information of the electronic device, the second position information of the followed object in the shooting preview interface, the first posture information and the first position information of the followed object in the shooting preview interface. This can make the followed object stably displayed in the shooting preview interface and keep the picture stable, thereby reducing the difficulty of shooting.

[0054] The first posture information and the second posture information can be understood as 6D posture information of the electronic device.

[0055] The first position information may be position information of the shooting selection area in the shooting preview interface. For example, the first position information may be a pixel position corresponding to the shooting selection area in the shooting preview interface.

[0056] The shooting selection area is the position information of the shooting object in the shooting preview interface.

[0057] In this embodiment, the second posture information may be obtained by measuring the posture of the electronic device using a gyroscope provided in the electronic device, or by measuring the posture of the electronic device using other equipment.

[0058] In some embodiments of the present application, the second position information can be determined by performing object recognition on the shooting preview interface to determine the display position of the tracking object in the shooting preview interface, and the above display position is used as the second position information.

[0059] In some embodiments of the present application, before controlling the front camera to capture a first image, the method further includes: displaying at least two camera movement trajectories to be selected; receiving a first input from a user for a first camera movement trajectory among the at least two camera movement trajectories to be selected; in response to the first input, displaying a gesture recording window, the gesture recording window being used to display a second image captured by the front camera; associating a matching gesture corresponding to the second image with the first camera movement trajectory; wherein the first image includes a matching gesture.

[0060] In this embodiment, the user can select the first camera movement trajectory through the first input, and obtain the matching gesture based on the second image captured by the front camera, and then bind the first camera movement trajectory with the matching gesture. In this way, when the camera movement trajectory is bound to the first camera, the first camera movement trajectory can be determined according to the matching gesture corresponding to the first image.

[0061] In some embodiments of the present application, displaying at least two camera movement trajectories to be selected includes: displaying a first shooting scene; receiving a selection input for the first shooting scene; and displaying a first window in response to the selection input, wherein M camera movement trajectories to be selected are displayed in the first window, where M is a positive integer greater than or equal to 2.

[0062] During this process, when the first shooting scene is selected, the first window is automatically displayed, making it convenient for the user to select the camera movement trajectory.

[0063] As shown in Figures 2 and 3, if the first shooting scene is underwater shooting, when the underwater shooting scene is selected, the first pop-up window 202 is displayed, wherein the first pop-up window 202 displays a reminder message of "Whether to import the shooting trajectory", and whether to display the first window 302 can be determined based on the user's input.

[0064] Specifically, when “Yes” displayed in the first pop-up window 202 is selected by the user, the first window 302 is displayed; otherwise, the electronic device directly enters the shooting mode.

[0065] In some embodiments of the present application, the first window 302 may be understood as a trajectory interface stored in the electronic device.

[0066] As shown in FIG3 , in the first window 302 , M camera movement tracks to be selected are displayed, namely, track 1 , track 2 , track 3 , track 4 , track 5 and track 6 .

[0067] In some embodiments of the present application, when the user selects track 2, track 3, and track 4, track 2, track 3, and track 4 can be used as camera movement tracks.

[0068] In some embodiments of the present application, as shown in FIG4 , the first window 302 further includes a confirmation control 402 . Based on this, the first input may be a click operation on M camera trajectories to be selected and a click operation on the confirmation control 402 .

[0069] In some embodiments of the present application, as shown in Figure 3, a first identifier 304 is also displayed in the first window, and the shooting method also includes: receiving a selection input for the first identifier; in response to the selection input for the first identifier, displaying O online camera movement trajectories, O is a positive integer greater than or equal to 1; receiving a selection input for P online camera movement trajectories among the O online camera movement trajectories, P≤O, and P is a positive integer; in response to the selection input for P online camera movement trajectories among the O online camera movement trajectories, updating and displaying at least two camera movement trajectories to be selected based on the P online camera movement trajectories.

[0070] In this embodiment, considering that the camera movement tracks stored locally in the electronic device may not meet the needs of the user, in this embodiment of the present application, a first indicator 304 is provided on the basis of the first window. When the user clicks the first indicator 304, O online camera movement tracks can be displayed. Then, according to the user's input, the selected P online camera movement tracks are downloaded to the local electronic device for use by the electronic device.

[0071] During this process, the number of camera movement tracks to be selected can be expanded, making it easier for users to select suitable camera movement tracks.

[0072] In some embodiments of the present application, the O online camera movement trajectories can be displayed using a new pop-up window, or they can be displayed based on the first window. The specific display method will not be repeated here.

[0073] In some embodiments of the present application, the method also includes: controlling the front camera to capture a third image; setting the second camera movement trajectory corresponding to the third image as the camera movement trajectory corresponding to the second camera in the rear camera; and displaying a second shooting preview screen corresponding to the second camera based on the second camera movement trajectory; wherein the second camera is different from the first camera.

[0074] In an embodiment of the present application, the front camera is controlled to perform image capture to achieve gesture detection, and then the second camera is bound to a mirror movement trajectory based on the captured third image, so that the electronic device can display the second shooting preview screen corresponding to the second camera based on the second mirror movement trajectory.

[0075] In this embodiment, by binding the second camera to the second camera movement trajectory, and then displaying the second shooting preview interface according to the second camera movement trajectory, there is no need for the user to manually move the camera, and the object to be shot can always be stably displayed in the shooting preview interface, so that the object to be shot can be shot with a stable camera movement trajectory, thereby reducing the difficulty of shooting.

[0076] In addition, in this embodiment, corresponding camera movement trajectories can be set for different cameras, so that multiple images after camera movement can be obtained in one shooting.

[0077] In some embodiments of the present application, the method further includes: displaying a third shooting preview screen; wherein the third shooting preview screen is associated with the first shooting preview screen and the second shooting preview screen; and outputting a fused video, wherein the screen content of the fused video is the same as the screen content of the third shooting preview screen.

[0078] In some embodiments of the present application, the first camera may be a main camera of the electronic device, and the second camera may be a camera other than the main camera in the electronic device.

[0079] In this embodiment, two cameras are used for shooting, so as to combine the shooting pictures using the first shooting picture and the second shooting picture, thereby outputting a fused video.

[0080] In some embodiments of the present application, the second camera may be a wide-angle camera.

[0081] In this embodiment, the main camera and the wide-angle camera are used in combination, which not only ensures the clarity of the subject being photographed, but also takes the shooting range into consideration, thereby restoring the user's perspective to the greatest extent.

[0082] In some embodiments of the present application, the first camera and the second camera are integrated into the same module, namely, a camera module, so that the distance between the two is relatively fixed, thereby obtaining the same shooting posture and achieving a unified shooting perspective.

[0083] In some embodiments of the present application, a camera movement track is set for each of the first camera and the second camera, so as to achieve the fusion of images captured by different camera movement tracks, thereby obtaining more shooting effects.

[0084] In some embodiments of the present application, the third shooting preview screen is associated with the first shooting preview screen and the second shooting preview screen, including: when the shooting object is detected in the first shooting preview screen and the second shooting preview screen, obtaining the main image including the shooting object in the first shooting preview screen, and obtaining the background image excluding the main image in the second shooting preview screen; and obtaining the third shooting preview screen based on the main image and the background image.

[0085] In this embodiment, the main camera has a higher pixel of the image it captures, while the second camera has a lower pixel of the image it captures.

[0086] By acquiring the subject image and the background image, a fused image is obtained by fusing the subject image and the background image, so as to ensure the clarity of the photographed object while taking into account the shooting range and improving the shooting effect.

[0087] In some embodiments of the present application, image recognition is performed on the image captured by the first camera and image recognition is performed on the image captured by the second camera, wherein, after image recognition is performed on the image captured by the first camera, first contour information corresponding to the tracking object is obtained, and after image recognition is performed on the image captured by the second camera, second contour information corresponding to the tracking object is obtained, and the image captured by the first camera is cropped based on the first contour information to obtain a main image; and the image captured by the second camera is cropped based on the second contour information to obtain a background image.

[0088] The fused image is obtained by stitching the subject image and the background image.

[0089] The photographed object is also the user's follow-up object.

[0090] In some embodiments of the present application, as shown in FIG5 , the display screen of the electronic device includes a first display area 502, a second display area 504, and a third display area 506. The first display area 502 is used to display a first shooting preview screen, the second display area 504 is used to display a second shooting preview screen, and the third display area 506 is used to display a third shooting preview screen.

[0091] In some embodiments of the present application, when at least one of the images captured by the first camera and the images captured by the second camera does not detect a tracking object, the third shooting preview screen displays the image captured by the first camera.

[0092] In this process, unnecessary energy consumption can be reduced when no tracking object is detected, thereby reducing the energy consumption of electronic devices and extending the standby time.

[0093] In some embodiments of the present application, the shooting method also includes: obtaining a first shooting duration corresponding to the first camera movement trajectory and a second shooting duration corresponding to the second camera movement trajectory; when the first shooting duration is greater than the second shooting duration, performing frame extraction processing on the image frame sequence captured by the first camera so that the shooting duration corresponding to the first shooting preview screen is consistent with the second shooting duration; or when the first shooting duration is less than the second shooting duration, performing frame extraction processing on the image frame sequence captured by the second camera so that the shooting duration corresponding to the second shooting preview screen is consistent with the first shooting duration.

[0094] In this embodiment, frame extraction processing is performed so that the shooting time corresponding to the first shooting preview screen is consistent with the second shooting time, or the shooting time corresponding to the second shooting preview screen is consistent with the first shooting time, so that when the screen fusion is performed, a shooting effect with consistent time can be obtained.

[0095] In some embodiments of the present application, before controlling the front camera to capture the first image, the method further includes: displaying preview images corresponding to the first camera and the third camera in the rear camera; receiving a second input from the user; and in response to the second input, selecting the preview image of the first camera.

[0096] In this embodiment, the third camera may be the second camera, or may be a camera different from the second camera.

[0097] In this embodiment, the camera to be set can be selected according to the user's operation, so as to set the associated camera movement trajectory for the camera.

[0098] Specifically, the second input may be a pressing operation of a volume up key of the electronic device.

[0099] In this embodiment, the electronic device can enable the first mirror movement track and the second mirror movement track by recognizing the user's gesture.

[0100] During this process, the user does not need to manually press the electronic device to activate the first camera movement track and the second camera movement track, thereby improving the convenience of starting the camera movement.

[0101] During this process, the user can use the front camera to control whether the first camera and the second camera enable the corresponding first camera movement track and second camera movement track while watching the display screen of the electronic device.

[0102] Specifically, taking the scene of underwater shooting as an example, due to the seabed pressure and water flow, the electronic device cannot remain stable under the disturbance of water flow. At the same time, the user cannot control it by pressing buttons or touching the screen, making it impossible to stabilize the follow-up object in the shooting preview interface. In the embodiment of the present application, while using the first camera movement track and the second camera movement track for camera shooting, the user does not need to manually press buttons or touch the screen to enable the camera movement track, thereby improving the convenience of shooting.

[0103] In some embodiments of the present application, when the first camera operates according to the previous camera movement trajectory, if a first image is captured, the shooting method further includes: after the first camera finishes operating according to the previous camera movement trajectory, continuing to record according to the first camera movement trajectory until the first camera movement trajectory ends.

[0104] In some embodiments of the present application, when the first camera is not operating along a camera movement trajectory, if the first image is captured, the shooting method further includes: upon receiving an input to start recording, recording according to the first camera movement trajectory until the first camera movement trajectory ends.

[0105] The input for starting recording may be pressing a power button of the electronic device.

[0106] In some embodiments of the present application, after the camera movement trajectory consistent with the user's gesture image is bound to the first camera, vibration + text is used to prompt the user that the binding is successful.

[0107] In some embodiments of the present application, the preview screen of the second camera is in the selected state by pressing the volume down key, which will not be described in detail here.

[0108] In some embodiments of the present application, the shooting method further includes: controlling the front camera to capture M images, the M images including gesture images corresponding one-to-one to M camera movement trajectories to be selected; and associating the M gesture images with the M camera movement trajectories to be selected.

[0109] In some embodiments of the present application, as shown in FIG. 6 , the electronic device can display a second window, wherein the second window displays a first information box 602 , a second information box 604 and a gesture preview interface 606 .

[0110] Specifically, the first information box 602 is used to display the selected camera track, such as the track cover thumbnail and name. The second information box 604 is used to display the prompt message "Please enter gesture". The gesture preview interface 606 is a rectangular box surrounded by dotted lines, which is used to display the recognized gesture.

[0111] As shown in Figures 7, 8, and 9, after a gesture is recognized, a 3-second countdown will begin. If the gesture remains unchanged within 3 seconds, the binding gesture is successful, and the color of the rectangular box turns into a green solid line box.

[0112] As shown in Figure 10, the second window displays a prompt mark 1002, wherein the prompt mark 1002 is used to indicate that the gesture image is bound to the next selected camera trajectory. If the prompt mark 1002 receives the user's input, the content displayed in the first information box, the content displayed in the gesture preview interface, and the color and virtuality and reality of the rectangular box are updated.

[0113] As shown in Figure 11, if there is no next camera movement track to be selected, a pop-up window 1102 will be displayed, in which the pop-up window 1102 shows that the power button has been clicked to start recording. If the user has no shooting needs at this time, he can directly exit the current interface. The gesture matching will still be saved until the user deletes the camera movement track or re-matches the gesture for the camera movement track.

[0114] In some embodiments of the present application, obtaining the camera movement trajectory also includes: in a trajectory recording mode, displaying a preview interface, the preview interface including at least one candidate shooting object; receiving a third input from the user for a first candidate shooting object among the at least one candidate shooting object; in response to the third input, displaying a selection box in a display area corresponding to the first candidate shooting object; receiving a fourth input from the user; and in response to the fourth input, recording the candidate camera movement trajectory based on the first candidate shooting object.

[0115] In this embodiment, the user can customize the recording of the camera movement trajectory to be selected, which can reduce the problem that the existing camera movement trajectory does not match the current shooting scene and affects the shooting effect.

[0116] In some embodiments of the present application, the fourth input may be a selection operation to confirm the selection of the to-be-selected photographing object.

[0117] In some embodiments of the present application, the process of recording the camera movement trajectory to be selected further includes: obtaining posture information of the electronic device, and binding the posture information of the electronic device to the camera movement trajectory to be selected.

[0118] Specifically, as shown in FIG12 , the preview interface has three objects to be selected, namely, a first object to be selected 1201, a second object to be selected 1202, and a third object to be selected 1203. When a click operation is received on the first object to be selected, a selection box will be displayed in the area where the first object to be selected is located.

[0119] In some embodiments of the present application, the selection box includes a first type of selection box and a second type of selection box, and the shooting method further includes: when the first type of selection box and the second type of selection box are displayed in the preview interface, and the camera movement trajectory corresponding to the first type of selection box is inconsistent with the camera movement trajectory corresponding to the second type of selection box, recording the camera movement trajectory corresponding to the second type of selection box.

[0120] In this embodiment, by setting the first category selection box and the second category selection box, corresponding priorities are set for different categories of selection boxes. Therefore, when the mirror movement trajectory corresponding to the first category selection box is inconsistent with the mirror movement trajectory corresponding to the second category selection box, the mirror movement trajectory corresponding to the second category selection box is recorded, that is, the mirror movement trajectory corresponding to the higher priority is recorded.

[0121] In some embodiments of the present application, when there are multiple first-category selection boxes and the selection boxes do not include second-category selection boxes, the shooting method further includes: recording the camera movement trajectory corresponding to the first selection box; wherein the area value of the first selection box is greater than the area value of the second selection box, and the second selection box is a selection box in the first category of selection boxes other than the first selection box.

[0122] In this embodiment, the camera movement trajectory corresponding to the selection box with a larger area value is recorded first, so as to meet the recording needs in actual scenes and ensure the overall effect of the recorded picture.

[0123] In some embodiments of the present application, after a selection box is displayed in a display area corresponding to a first object to be selected, the shooting method further includes: receiving a fifth input from the user to the selection box; and updating display parameters of the selection box in response to the fifth input; wherein the display parameters of the selection box are associated with the camera trajectory to be selected.

[0124] In this embodiment, the user can adjust the display parameters of the selection box according to actual needs, thereby realizing the setting of the camera movement, thereby improving the camera movement effect.

[0125] The display parameter may be a display size or a display position, and the fifth input may be a two-finger zoom-in operation of the user on the selection box.

[0126] In some embodiments of the present application, the shooting method further includes: receiving a drag input of the selection box; and in response to the drag input, changing the display position of the selection box on the preview interface.

[0127] In some embodiments of the present application, as shown in FIG. 13 and FIG. 14 , the user can move the size of the selection box and adjust the size of the object to be selected by operation.

[0128] In one embodiment, as shown in Figures 15 and 16, suppose a user is filming a school of fish in situ and wants to capture the fish swimming at a constant speed from right to left within a fixed area, with the background gradually zooming in. A pre-set camera movement is already set: Gesture 3 represents the subject's constant movement from right to left within a fixed area, while Gesture 2 represents the background's constant zooming in.
