[0034] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0035] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0036] The following is a detailed description of the shooting method and shooting device provided in the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0037] See also Figure 1 , an embodiment of the present application provides a shooting method, the method comprising:

[0038] S110, when displaying a shooting preview picture, identifying an object in the shooting preview picture to obtain a reference object and at least one non-reference object;

[0039] During the process of taking photos or videos, a shooting preview screen is displayed for users to view the shooting scene or picture in real time, so that users can instantly view the shooting effect, shooting parameters, and composition. When the electronic device is in shooting preview mode, the camera module shoots at a preset frame rate to generate a shooting preview screen, and displays the shooting preview screen through the display module for users to browse.

[0040] In some embodiments of the present application, at least two shooting modes are provided. In the first shooting mode, a shooting preview screen is displayed, and the object in the shooting preview screen is not identified. When the shooting input is received, a shooting image is generated based on the shooting preview screen. In the second shooting mode, a shooting preview screen is displayed, and the object in the shooting preview screen is identified to obtain a reference object and at least one non-reference object. The second shooting mode can be a "shoot the same style" mode, and the user can manually turn on or off the "shoot the same style" mode provided in the embodiment of the present application. Exemplarily, the user can instruct the mobile phone to turn on the camera application by touching a specific control on the mobile phone screen, pressing a specific physical key or key combination, inputting a voice, making an air gesture, etc. In response to receiving an instruction from the user to turn on the camera, the camera application is started, the shooting module shoots, and the shooting preview screen is displayed. When the "shoot the same style" mode is turned on, that is, in the second shooting mode, the electronic device can identify the object displayed in the shooting preview screen. If the "shoot the same style" mode is not turned on, that is, in the first shooting mode, the electronic device displays the shooting preview screen and does not identify the object displayed in the shooting preview screen.

[0041] When the display interface displays the shooting preview screen, it also displays the setting controls, photo controls, video controls and other functional controls (such as portrait mode controls, night scene mode controls, movie mode controls or more other controls). Exemplarily, the shooting preview screen displays the first control, and the first control is used to turn on or off the "shoot the same style" mode. The user turns on the "shoot the same style" mode by clicking the first control, and identifies the object in the shooting preview screen when the shooting preview screen is displayed.

[0042] When one or more objects are displayed in the shooting preview screen, the pre-stored object detection algorithm can identify the objects in the shooting preview screen to divide them into images showing different objects. The objects can be buildings, landscapes, plants, animals, people, etc.

[0043] After identifying multiple objects in the shooting preview screen, one or more of the multiple objects can be deleted or multiple identified objects can be merged into the same object according to the user's input operation. It is also possible to determine that one of the multiple objects is a reference object and at least one object is a non-reference object according to the user's input operation. For example, see Figure 2 , the pyramid, person A and person B in the real scene are photographed, and the shooting preview screen shot in the electronic device displays the pyramid 21, person A22, person B23, person C and obstacle D. The objects in the shooting preview screen are identified, and the objects include the pyramid 21, person A22, person B23, person C25 and obstacle 24. The user can delete the person C25 in the identified object, and can also merge the person A22 in the identified object and the person B23 in the identified object into the same object. The user can also select the pyramid 21 in the identified object as a reference object, and the person A22 and person B23 merged into the same object, and the obstacle 24 in the identified object as a non-reference object.

[0044] The electronic device may also send the identified images showing different objects to a cloud server, and the cloud server may identify a reference object and at least one non-reference object among the multiple objects. Optionally, the electronic device may also send information such as the shooting location and time to the cloud server to improve the accuracy of the cloud server in distinguishing between the reference object and the non-reference object.

[0045] Optionally, the reference object is a marker with specific characteristics, including landmark buildings and iconic geological features. For example, landmark buildings can be the Sydney Opera House, the Eiffel Tower in Paris, the Tiananmen Square in Beijing, the Statue of Liberty in New York, etc. Iconic geological features can be the Hukou Waterfall of the Yellow River, Mount Fuji in Japan, the Grand Canyon in Colorado, etc.

[0046] S120, acquiring image feature information of the shooting template and a three-dimensional model of a reference object, wherein the image feature information includes first-viewing angle information of the reference object;

[0047] The shooting template may be a fused image file generated in advance based on one or more popular images or videos about the reference object. The shooting template has the common features of one or more popular images or videos. Figure 3 For example, a plurality of popular images 31 about the reference object are obtained, characteristic information of the reference object displayed in the popular images 31 is extracted, and a shooting template 32 is generated. The characteristic information includes shooting angle information of the reference object, and the shooting angle information is the first angle information of the reference object.

[0048] The image feature information may also include position information, size information, depth of field information, exposure information, color temperature information, etc. of the reference object in the shooting template.

[0049] A virtual three-dimensional model of the corresponding reference object can be generated based on the texture information, depth of field information, size information, etc. contained in the three-dimensional model. The real reference object can be scanned in advance to obtain the three-dimensional model of the reference object. The real reference object can also be photographed from multiple angles in advance, and the three-dimensional model of the reference object can be generated based on images from different shooting angles.

[0050] S130, adjusting the reference object in the shooting preview picture shot at the second viewing angle to be displayed at the first viewing angle according to the image feature information and the three-dimensional model of the reference object;

[0051] The second perspective is the perspective of the user's electronic device taking pictures of the real environment, such as Figure 4 The range shown by the dotted line is the range corresponding to the second viewing angle. The first viewing angle and the second viewing angle may be the same or different. When a user shoots a reference object in a real environment, due to environmental factors, the geographical location of the electronic device held by the user relative to the reference object cannot be maintained at the first viewing angle when shooting the reference object. By adjusting the reference object shot at the second viewing angle in the shooting preview screen to the reference object displayed at the first viewing angle, a shooting preview screen displaying the reference object at the first viewing angle can be obtained. The reference object displayed at the first viewing angle can be understood as a three-dimensional model projected at the first viewing angle on the shooting preview screen currently being shot.

[0052] It can be understood that in order to ensure the authenticity of the shooting preview screen, except for the reference object in the shooting preview screen which is adjusted to the first perspective display, the non-reference objects in the shooting preview screen are all maintained in the second perspective display state, that is, the non-reference objects in the shooting preview screen are displayed in the real perspective of the electronic device in real time.

[0053] For example, see Figure 4 , among which, Figure 4 As shown in (a), when the "shoot the same style" mode is not turned on, the electronic device shoots objects in the real environment in real time, shoots the landmark building 41 and the person 42 from a second perspective, and the generated shooting preview screen shows the side of the landmark building 41, and the person 42 stands on the right side of the landmark building 41.

[0054] like Figure 4 As shown in (b), when the "shoot the same style" mode is turned on, the electronic device shoots the objects in the real environment in real time, identifies the landmark building 41 and the person 42, and sends the identified landmark building 41 and the person 42, as well as the shooting time and location to the cloud server. The image feature information of the shooting template of the landmark building 41 and the three-dimensional model of the landmark building 41 sent by the cloud server are received, and the reference object displayed in the shooting preview screen is adjusted according to the image feature information of the shooting template and the three-dimensional model. The generated shooting preview screen displays the landmark building 41 shot from the first perspective, that is, the front of the landmark building 41 is displayed, and the person 42 shot from the second perspective is displayed.

[0055] S140, receiving a first input;

[0056] S150 , in response to the first input, generating a captured image based on the captured preview picture.

[0057] When the electronic device displays a shooting preview screen, a first input is received, and the first input may be a single click, double click, long press, etc., made on a control, image, frame, etc. displayed on the shooting preview screen, or a specific sliding gesture made, a voice command issued, etc. The first input is used to instruct the camera module to shoot an image.

[0058] In response to the first input, the camera module is mobilized to generate a captured image according to the captured preview screen. The adjusted relative spatial position relationship between the reference object and the non-reference object in the captured preview screen is the same as the relative spatial position relationship between the reference object and the non-reference object in the captured image. The reference object displayed in the first perspective in the captured preview screen is the same as the perspective of the reference object displayed in the captured image.

[0059] In the shooting method provided in the present application, by acquiring the image feature information of the shooting template and the three-dimensional model of the reference object, the reference object in the shooting preview screen shot at the second perspective is adjusted to be displayed at the first perspective according to the image feature information and the three-dimensional model of the reference object, so that the user can imitate the shooting template to obtain a shot image showing the reference object at the first perspective without changing the geographical location of the shooting module relative to the reference object, so as to avoid the situation where the image shot due to environmental factors cannot replicate the reference object displayed in the shooting template.

[0060] In some embodiments, after S130, the following steps are included:

[0061] S210: Adjust the relative spatial position relationship between the reference object and at least one non-reference object in the shooting preview picture according to the image feature information.

[0062] The image feature information of the shooting template includes the spatial position relationship between the reference object and the non-reference object in the shooting template, and the relative spatial position relationship between the reference object and the at least one non-reference object in the shooting preview screen can be adjusted according to the spatial position relationship of the shooting template. The image feature information of the shooting template can also include the spatial position relationship of the preset reference object and the non-reference object, and the relative spatial position relationship between the reference object and the at least one non-reference object in the shooting preview screen can be adjusted according to the preset spatial position relationship of the reference object and the non-reference object.

[0063] Adjust the relative spatial position relationship between the reference object and at least one non-reference object in the shooting preview screen so that the displayed reference object and non-reference object can replicate the spatial position relationship of the shooting template, avoid a serious sense of disharmony caused by a large difference in size and position of the reference object and non-reference object, and make the display of the reference object and non-reference object in the shooting preview screen conform to real visual habits.

[0064] In some embodiments, S210 may include at least one of the following:

[0065] When the image feature information includes size information of the reference object in the template image, adjusting the relative size ratio of the reference object and at least one non-reference object in the shooting preview image according to the size information of the reference object in the template image;

[0066] When the image feature information includes position information of the reference object in the template image, adjusting the relative display positions of the reference object and at least one non-reference object in the shooting preview screen according to the position information of the reference object in the template image;

[0067] When the image feature information includes depth information of the reference object in the template image, the relative depths of the reference object and at least one non-reference object in the shooting preview image are adjusted according to the depth information of the reference object in the template image.

[0068] For example, see Figure 4 , among which, Figure 4 As shown in (a), when the "shoot the same style" mode is not turned on, the electronic device shoots objects in the real environment in real time, shoots the landmark building 41 and the person 42 from a second perspective, and the generated shooting preview screen shows the side of the landmark building 41, and the person 42 stands on the right side of the landmark building 41.

[0069] like Figure 4As shown in (b), when the "shoot the same style" mode is turned on, the image feature information of the shooting template of the landmark building 41 and the three-dimensional model of the landmark building 41 are obtained, and the reference object displayed in the shooting preview screen is adjusted according to the image feature information and the three-dimensional model of the shooting template. The generated shooting preview screen displays the landmark building 41 shot from the first perspective, that is, the front of the landmark building 41 is displayed; the generated shooting preview screen displays the person 42 shot from the second perspective standing in front of the landmark building 41, and the person 42 is displayed in a larger size relative to the landmark building 41.

[0070] In some embodiments, the image feature information may further include visual effect parameters, which may include filter parameters, sticker parameters, subtitle parameters, etc. After S130, visual effects may be added to the preview image according to the image feature information.

[0071] In some embodiments, after S110, the following steps are included:

[0072] Establish corresponding layers for the reference object and each non-reference object respectively;

[0073] S130 includes:

[0074] Adjust the reference object to display in the first person perspective for the layer that displays the reference object;

[0075] S210 includes:

[0076] At least one of a relative size relationship, a relative position relationship, and a relative depth relationship between a layer displaying a reference object and each layer displaying non-reference objects in a shooting preview screen is adjusted according to the image feature information.

[0077] By creating separate layers for reference objects and non-reference objects, it is convenient to adjust the reference objects and non-reference objects independently of other layers.

[0078] In some embodiments, the shooting preview screen is a fused image including multiple layers, where the multiple layers include a layer for displaying a reference object and a layer for displaying a non-reference object; after S130, the following steps are included:

[0079] S310, receiving a second input of a first layer among the multiple layers;

[0080] S320: In response to the second input, adjust the spatial position of the object displayed in the first layer in the shooting preview picture.

[0081] When the shooting preview screen adjusted by the image feature information and the three-dimensional model does not meet the user's requirements, the user can make a second input to the first layer among the multiple layers to adjust the size, position, depth of field, layer order and other spatial positions of the object displayed by the first layer in the shooting preview screen. When the first layer is a layer for displaying reference objects, the objects displayed by the first layer are reference objects; when the first layer is a layer for displaying non-reference objects, the objects displayed by the first layer are non-reference objects.

[0082] Since the user can trigger the conventional functions of multiple non-adjustment layers by performing multiple conventional inputs on the shooting preview screen. Conventional functions may include adjusting the brightness of the shooting preview screen, adjusting the focal length of the shooting preview screen, adjusting the exposure time of the captured image, etc. A locked state and an unlocked state may be set for the shooting preview screen to distinguish the conventional input and the second input performed by the user on the preview interface. The user can manually switch between the locked state and the unlocked state. Exemplarily, the user can indicate the switch between the locked state and the unlocked state by touching a specific control on the mobile phone screen, pressing a specific physical key or key combination, inputting a voice, performing an air gesture, etc. Exemplarily, the shooting preview screen displays a second control, and the second control is used to switch between the locked state and the unlocked state. The user switches to the unlocked state by clicking the second control and executes S310. The user switches to the locked state by clicking the second control, and does not respond when receiving the second input to the first layer of the multiple layers.

[0083] The second input may be a click, a long press, a rotation, a zoom, a translation, etc. of a first layer among the multiple layers.

[0084] Optionally, a translation input for a first layer among the multiple layers is received; in response to the translation input, a display position of an object displayed in the first layer in the shooting preview screen is adjusted. Figure 5 ,like Figure 5 As shown in (a), the person 42 is located in front of the right side of the landmark building 41, and the person 42 is selected and translated; Figure 5 As shown in (b), the person 42 is located in front of the left side of the landmark building 41.

[0085] Optionally, a rotation input of a first layer among the multiple layers is received; in response to the rotation input, an object displayed in the first layer in the shooting preview screen is rotated. Figure 6 ,like Figure 6 As shown in (a), the landmark building 41 is displayed in the horizontal direction, and the landmark building 41 is selected and rotated; Figure 6 As shown in (b), the landmark building 41 is deflected at a certain angle.

[0086] Optionally, a two-finger movement input is received for a first layer of the multiple layers; in response to the two-finger movement input, an object displayed in the first layer is scaled in the shooting preview screen. Figure 7 ,like Figure 7 As shown in (a), the character 42 is displayed in the first size, the character 42 is selected, and two fingers are moved away from each other; Figure 7 As shown in (b), the character 42 is displayed in a larger size.

[0087] In some embodiments, the shooting preview screen is a fused image including multiple layers, where the multiple layers include a layer for displaying a reference object and a layer for displaying a non-reference object; after S130, the following steps are included:

[0088] S410, receiving a third input of a second layer displaying a reference object among the multiple layers;

[0089] S420, in response to the third input, switching the display state of the second layer to an unlocked state;

[0090] S430, obtaining a change angle of viewing angle for shooting a preview image;

[0091] S440, generating a third perspective according to the perspective change angle and the first perspective;

[0092] S450: According to the three-dimensional model, the reference object in the second layer is adjusted to be displayed in a third perspective.

[0093] The area where the reference object is displayed in the shooting preview screen can be long-pressed to select the second layer, display the lock control associated with the second layer, and click the lock control to switch the display state of the second layer between the locked state and the unlocked state. The second layer can be set to be in the locked state by default to prevent the reference object displayed in the shooting preview screen from changing as the viewing angle of the shooting preview screen changes.

[0094] When the user moves the electronic device, the viewing angle of the preview image captured by the camera module in the electronic device changes, and the viewing angle change angle is used to characterize the amount and direction of the change in the shooting viewing angle. Since the three-dimensional model is obtained, the reference object displayed in the first viewing angle can change along with the viewing angle change angle.

[0095] In some embodiments, when the second layer is selected and a lock control associated with the second layer is displayed, a layer adjustment control is also displayed, and a click input to the layer adjustment control is received to adjust the order of the second layer in the multiple layers.

[0096] For example, see Figure 8 ,like Figure 8As shown in (a), after the "shoot the same style" mode is turned on, the generated shooting preview screen shows the landmark building 41 shot from the first perspective, that is, the front of the landmark building 41 is shown; the generated shooting preview screen shows the person 42 shot from the second perspective standing in front of the landmark building 41. Figure 8 As shown in (b), the user moves the electronic device, and the person 42 displayed in the shooting preview screen changes with the shooting angle, and the display state of the landmark building 41 is in a locked state, and the angle of displaying the landmark building 41 does not change with the shooting angle.

[0097] like Fig. 9 As shown in (a), after the "shoot the same style" mode is turned on, the generated shooting preview screen shows the landmark building 41 shot from the first perspective, that is, the front of the landmark building 41 is shown; the generated shooting preview screen shows the person 42 shot from the second perspective standing in front of the landmark building 41. Fig. 9 As shown in (b), long press the area showing the landmark building 41 in the shooting preview screen to select the second layer of the landmark building 41, and the floating window displays the lock control 91 and the layer adjustment control 92 associated with the second layer. Click the lock control 91 to switch the display state of the second layer to the unlocked state. Fig. 9 As shown in (c), the user moves the electronic device, and the person 42 displayed in the shooting preview screen changes with the shooting angle. The landmark building 41 is in an unlocked state, and the angle of displaying the landmark building 41 changes with the shooting angle.

[0098] In some embodiments, the layer where the first non-reference object is located can be selected from at least one non-reference object, and the display state of the layer can be switched from an unlocked state to a locked state, so that the layer displaying the first non-reference object does not change with the shooting angle, and the layers of other non-reference objects in the unlocked state change in real time with the shooting angle.

[0099] In some embodiments, the shooting preview screen is a fused image including multiple layers, where the multiple layers include a layer for displaying reference objects and a layer for displaying non-reference objects; S130 includes:

[0100] S510, receiving a fourth input of a second layer displaying a reference object among the multiple layers;

[0101] S520, in response to a fourth input, obtaining a first sight adjustment angle;

[0102] S530, generating a fourth perspective according to the first sight line adjustment angle and the first perspective;

[0103] S540: According to the three-dimensional model, in the shooting preview screen, adjust the reference object in the second layer to be displayed at a fourth viewing angle.

[0104] The perspective of displaying the reference object is the core of the photo. The first sight adjustment angle is the angle that the user needs to adjust to shoot the reference object displayed in the preview screen. Since there is a three-dimensional model of the reference object, the reference object can be adjusted to display in the fourth perspective according to user needs in the shooting preview screen, realizing the rotation, scaling, translation, etc. of the reference object in the three-dimensional space.

[0105] For example, see Fig.10 ,like Fig.10 As shown in (a), after the "shoot the same style" mode is turned on, the generated shooting preview screen shows the landmark building 41 shot from the first perspective, that is, the front of the landmark building 41 is shown; the generated shooting preview screen shows the person 42 shot from the second perspective standing in front of the landmark building 41. Fig.10 As shown in (b), a two-finger operation is performed on the area displaying the landmark building 41 in the shooting preview screen to select the second layer of the landmark building 41. The landmark building 41 photographed from the fourth perspective is displayed according to the moving trajectory of the two fingers, that is, the landmark building 41 is displayed with a deflection, and the left part of the landmark building 41 obscures the main part of the landmark building 41.

[0106] In some embodiments, S150 includes:

[0107] S610, in the photography mode, generating a captured image based on the captured preview screen;

[0108] S620, in the video recording mode, generating a video file including a plurality of captured images according to the captured preview screen displayed on the captured preview screen.

[0109] When the camera application or electronic device is in photography mode, clicking the photography control generates a captured image based on the shooting preview screen. The reference object and non-reference object displayed in the captured image are consistent with the reference object and non-reference object displayed in the preview interface.

[0110] When the camera application or electronic device is in recording mode, click the recording control, and multiple frames of shooting images are generated in sequence according to the shooting preview screen displayed on the shooting preview screen to form a video file. For the recording mode, the shooting template can be a video template about the reference object. During the recording process, the shooting preview screen adjusts the screen in real time according to the spatial information of the image of the same time frame in the shooting template to ensure that the spatial position of the video file recorded by the user and the reference object displayed in the video template are consistent.

[0111] In some embodiments, in the video recording mode, a video file including a plurality of captured images is generated according to the captured preview screen displayed on the captured preview screen, including:

[0112] S710, in the shooting preview screen, at least one non-reference object changes with the shooting perspective;

[0113] S720, adjusting the display viewing angle of the reference object in the shooting preview picture according to the three-dimensional model so that the viewing angle of the shooting preview picture changes as the shooting viewing angle of the shooting preview picture changes;

[0114] S730, generating a video file according to the shooting preview picture.

[0115] During the process of recording a video, if the user moves the electronic device, the shooting angle of the non-reference objects in the real environment changes, and the non-reference objects in the shooting preview screen change in real time with the shooting angle. If the reference object in the shooting preview screen remains displayed in the first perspective, the recorded video file lacks a sense of reality. Through S720, the display angle of the reference object in the shooting preview screen changes with the shooting angle of the shooting preview screen, thereby improving the sense of reality of the recorded video file. For example: in the shooting preview screen, person A is located directly in front of a landmark building, and the user moves the camera module relatively located in front of person A to the right side of person A, then the shooting preview screen moves from the front of the landmark building to the front of the landmark building displayed from the side.

[0116] In some implementations, the shooting preview screen is a fused image including multiple layers, where the multiple layers include a layer for displaying a reference object and a layer for displaying a non-reference object; and the method further includes:

[0117] S810, receiving a fifth input of a second layer displaying a reference object among the plurality of layers when a video file is generated according to the shooting preview picture;

[0118] S820: In response to the fifth input, adjust the spatial position of the reference object in the shooting preview picture, and generate a video file including a changed picture of the reference object in the shooting preview picture.

[0119] When a video file is generated according to the shooting preview screen, each frame of the video file is continuously generated according to the shooting preview screen. A fifth input is received for a second layer displaying a reference object in multiple layers, and the size, position, depth of field, layer sorting and other spatial positions of the reference object displayed in the second layer in the shooting preview screen can be adjusted according to the fifth input. The generated video file includes the changing process of the reference object in the shooting preview screen to achieve a magical display effect. For example: if the reference object is rotated, the recorded video file shows the process of the reference object gradually rotating.

[0120] When the user switches to the paused recording state through the "Pause / Continue" control, the shooting preview screen is displayed, and the generation of the shooting image based on the shooting preview screen is paused. The user can make the aforementioned adjustments to the reference object and non-reference object in the shooting preview screen. When the user switches to the recording state through the "Pause / Continue" control, the adjusted shooting preview screen is displayed, and the shooting image is generated based on the adjusted shooting preview screen. The recorded video file does not display the adjustment process of the reference object and non-reference object in the paused recording state.

[0121] In some embodiments, the captured image is a fused image including multiple layers, wherein the multiple layers include a layer displaying a reference object and a layer displaying a non-reference object; and the method further includes:

[0122] receiving a sixth input of a third layer of the plurality of layers of the captured image;

[0123] In response to the sixth input, a spatial position of the object displayed in the third layer in the captured image is adjusted.

[0124] For the generated captured images, the third layer that needs to be adjusted can be selected, and the size, position, depth of field, layer order and other spatial positions of the reference object displayed in the third layer can be adjusted in the captured images to achieve re-editing of the captured images.
