[0029] 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.

[0030] 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.

[0031] The following is a detailed description of the shooting method and device provided by the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] At present, as users use electronic devices to take photos more and more frequently, the requirements for the shooting effect of electronic devices are also getting higher and higher. For example, when a user takes an image or video, a horizon correction process is required. The horizon correction process can be aimed at the problem of tilted lines in the picture collected by the camera due to the tilted field of view of the camera, and the tilted lines are corrected so that the lines that are actually parallel to the horizontal plane remain parallel to the horizontal plane in the image or video taken, and the lines that are actually perpendicular to the horizontal plane remain perpendicular to the horizontal plane in the image or video taken.

[0033] However, under the existing horizon correction shooting method, the electronic device always performs recognition and correction based on the content collected by a single camera. Due to the single field of view angle range, the recognition and correction effect is poor.

[0034] Based on this, the present application provides a shooting method, which can be applied to correct shooting scenes. Figure 1-Figure 8 The shooting method provided in the embodiment of the present application is described in detail. It should be noted that the shooting method provided in the embodiment of the present application can be executed by a shooting device. In the embodiment of the present application, the shooting method provided in the embodiment of the present application is described by taking a shooting device executing the shooting method as an example.

[0035] Figure 1 It is a flowchart of a shooting method provided by an embodiment of the present application.

[0036] like Figure 1 As shown, the shooting method may include steps: S110-S130, which are described in detail below.

[0037] S110: Receive a first input from a user on a target object displayed in a first shooting preview interface of an electronic device.

[0038] In the embodiment of the present application, the electronic device may include multiple cameras, and the first shooting preview interface may be a preview interface displayed when shooting is performed using one of the cameras.

[0039] In addition, the first input may be an input in which the user selects the target object displayed in the first shooting preview interface. The input method of the first input includes but is not limited to single-click, double-click, long press, etc. The target object includes but is not limited to a person, an object, a person and an object, etc.

[0040] Exemplarily, after the user selects the target object to be photographed through the first input, an object lock frame may be displayed in the first shooting preview interface and disappear after a preset time, so that the user can determine whether the selected target object is the object the user wants to photograph.

[0041] In some specific examples, when a user uses a mobile phone to shoot a certain object, the user can open the camera software in the mobile phone, enter the horizon correction mode, and display the preview interface of the current mobile phone camera on the screen, that is, the first shooting preview interface. When the user points the mobile phone camera at the object to be shot, the object to be shot can be displayed in the first shooting preview interface. Figure 2 As shown, if the user double-clicks to select the target object 21 displayed in the current preview interface, the focus tracking recognition can be turned on. After the target object 21 is recognized, the corresponding lock frame 22 can be displayed and the target object 21 can be locked. The lock frame 22 can disappear after 3 seconds, but the focus tracking will not be canceled.

[0042] S120: In response to the first input, the target object is displayed in a target area of ​​the second shooting preview interface based on images captured by multiple cameras of the electronic device.

[0043] Here, after the user selects the target object, the locked target object can be displayed in the target area of ​​the second shooting preview interface through the preset focus tracking algorithm and multiple cameras set on the electronic device. Among them, the multiple cameras set can include any multiple cameras of the main camera, 5X camera, 2X camera or wide-angle camera, for example.

[0044] In addition, the location of the target area can be determined according to actual needs, for example, it can be the central location area of ​​the second shooting preview interface, or it can be other areas that are convenient for correction processing, which is not limited here.

[0045] Exemplarily, this embodiment may select a camera having an optimal field of view for a target object from multiple cameras provided on the electronic device according to a preset focus tracking algorithm, so that the target object can be displayed in the central position area of ​​the shooting preview interface.

[0046] S130, correcting and photographing the image displayed on the second shooting preview interface to obtain a target image.

[0047] Here, the image frame displayed on the second shooting preview interface may be corrected to obtain a corrected shooting preview interface, and then shooting may be performed based on the corrected shooting preview interface to obtain a target image. The correction process may be, for example, a horizon correction process.

[0048] For example, the image information collected by the camera can be corrected in real time according to the preset horizon correction recognition algorithm, and the following can be obtained: Figure 3 The correction shooting preview interface shown in the figure may include a correctable area 31, and a preview image after horizon correction processing may be displayed in the correctable area 31.

[0049] In some implementations, after obtaining the correction shooting preview interface, the shooting method provided in the embodiment of the present application may further include:

[0050] receiving a second input from the user on the correction shooting preview interface;

[0051] In response to the second input, correction shooting is performed based on the correction shooting preview interface to obtain a target image.

[0052] Here, the second input may be a shooting trigger input performed by the user based on the corrected shooting preview interface obtained after horizon correction processing. The input method corresponding to the second input may include clicking a shooting button, or controlling the shooting through voice commands.

[0053] In some examples, the user can click on Figure 3 The photo button in the correction shooting preview interface shown is pressed to obtain the image displayed in the correctable area 31, that is, the target image.

[0054] In this way, by performing image capture based on the final correction capture preview interface after correction processing, the target object that the user wants to capture can always be kept within the target area, thereby improving the correction effect of the target object.

[0055] In addition, before the above S130, it can also be determined whether it is currently necessary to re-perform object tracking and recognition. If so, return to execute S120, if not, execute S130.

[0056] For example, if the user cancels the focus tracking, for example, by clicking Figure 2 , you can restore the default camera to shoot and restore the zoom ratio, such as 1x zoom range. When the user re-selects another object for focus tracking, the focus tracking state of the selected object can be triggered again.

[0057] Therefore, by locking the target object selected by the user while the user is using the electronic device to take pictures, the content that the user wants to shoot, that is, the target object, is displayed in the target area of ​​the second shooting preview interface based on the images captured by multiple cameras in the electronic device, and then correction processing and shooting are performed based on the second shooting preview interface to obtain the target image. In this way, since the embodiment of the present application shoots the target object based on multiple field of view angle ranges corresponding to multiple cameras, even if the user slightly offsets the electronic device, the multi-camera shooting technology can be used to present the target object that the user wants to shoot in a fixed area of ​​the shooting preview interface, which makes it easier to correct and shoot the target object, thereby improving the correction effect during image shooting and enhancing the user's shooting experience.

[0058] Based on the above S110-S130, in some embodiments, as Figure 4 As shown, the above S120 may specifically include:

[0059] S1201, determining a display area corresponding to a target object in a first shooting preview interface;

[0060] S1202, when the display area does not match the target area, switching a first camera in the electronic device that captures the target object to a second camera;

[0061] S1203: Capture a target object through the second camera, and display the target object in a target area of ​​the second shooting preview interface.

[0062] Here, the mismatch between the display area and the target area may include at least one of position mismatch and size mismatch.

[0063] Exemplarily, when the display area does not match the target area, the camera being used, i.e., the first camera, can be switched to adjust the field of view angle range, and then the target object is photographed based on the field of view angle range corresponding to the switched camera, i.e., the second camera, so that the target object is displayed in the target area of ​​the second shooting preview interface, thereby achieving the effect of matching the display area corresponding to the target object with the size of the target area.

[0064] In addition, after switching to the second camera, if the target object is still not displayed in the target area of ​​the second shooting preview interface, the magnification of the second camera can be adjusted until the target object is displayed in the target area so that the display area corresponding to the target object matches the size of the target area.

[0065] In this way, by switching the first camera being used to the second camera when there is a mismatch between the display area corresponding to the target object and the target area, a shooting field of view matching the target object can be obtained, so that the target object is displayed in the target area of ​​the second shooting preview interface. In this way, the success rate of correction and recognition of the target object can be improved, and the correction effect can be improved.

[0066] In addition, in some implementations, before the step of switching the first camera for capturing the target object in the electronic device to the second camera, the shooting method provided in the embodiment of the present application may further include:

[0067] Obtaining difference information between the display area and the target area;

[0068] According to the difference information, a target camera whose field of view angle matches the target object is determined from multiple cameras, and the target camera includes the second camera.

[0069] Here, the difference information may include at least one of size difference information and position difference information. The number of target cameras may be one or more, that is, there may be one or more cameras whose field of view angles match the target object, and then a camera is randomly selected or selected according to a preset rule as the second camera to be finally switched.

[0070] In this way, by determining the camera whose field of view matches the target object from multiple cameras based on the difference information between the display area and the target area, and then determining to switch to the second camera, the camera suitable for the target object can be accurately found, thereby improving the camera switching efficiency and quickly locating the suitable camera for the current shooting scene.

[0071] In some embodiments, the step of determining, from a plurality of cameras, a target camera whose field of view matches the target object according to the difference information, wherein the target camera includes a second camera, may specifically include:

[0072] When it is determined according to the difference information that the display area is smaller than the target area, a camera having a smaller field of view angle than the first camera is determined from the multiple cameras as the target camera;

[0073] When it is determined according to the difference information that the display area is larger than the target area, or the position offset of the display area relative to the target area exceeds a preset threshold, a camera having a field of view greater than the first camera is determined from multiple cameras as the target camera.

[0074] In some specific examples, if the camera currently being used is the main camera, such as Figure 5 As shown in FIG. 1 , when the target object 51 for tracking is identified to be close, the display area 52 corresponding to the target object 51 is larger than the target area 53. Therefore, according to the size difference information between the two, the wide-angle camera with a larger field of view than the main camera can be automatically switched to obtain a better field of view; Figure 6 As shown in FIG. 1 , when the target object 61 is far away, the display area 62 corresponding to the target object 61 is smaller than the target area 63. Therefore, according to the size difference information between the two, the 2X camera with a smaller field of view than the main camera can be automatically switched to the display area 62 corresponding to the target object 61. Figure 6 5X camera as shown; Figure 7 As shown, if the mobile phone offsets the target object 71, the target object 71 may not be fully displayed in the preview image taken by the current camera, that is, the position difference between the display area 72 and the target area 73 corresponding to the target object 71 is relatively large. For example, if the position offset of the display area 72 relative to the target area 73 exceeds a preset threshold, the camera can be automatically switched to a wide-angle camera with a larger field of view than the main camera based on the position difference information between the two.

[0075] In addition, if Figure 6 As shown, if the user moves the phone slightly, the 5X camera can be switched to the 2X camera, the main camera lens or the wide-angle lens to obtain a larger field of view, and then the magnification can be adjusted so that the target object of focus is displayed in the center of the camera preview interface.

[0076] In this way, by determining a camera whose field of view angle matches the target object from multiple cameras according to the size difference or position difference between the display area and the target area, a camera suitable for the target object can be accurately found.

[0077] Based on this, in some implementations, when the positions of the display area and the target area do not match, the shooting method provided in the embodiment of the present application may further include:

[0078] Acquire a region image corresponding to the display region in the first shooting preview interface;

[0079] The regional image is displayed in the target area of ​​the second shooting preview interface.

[0080] For example, after switching the camera, if the target object is still not displayed in the target area of ​​the second shooting preview interface, the area image corresponding to the display area in the first shooting preview interface can be cropped, and the cropped area image can be moved to the target area of ​​the second shooting preview interface so that the target object is displayed in the target area.

[0081] In some specific examples, such as Figure 8 As shown, if the camera currently used by the mobile phone is the main camera, when the target object 81 is close and offset relative to the mobile phone camera, the mobile phone can automatically switch to the wide-angle lens and crop the image of the area 82 where the target object 81 is located, and then display the area image within the area 82 in the center of the shooting preview interface.

[0082] In this way, through image cropping, when the target object cannot be displayed in the target area even through lens switching, the regional image corresponding to the target object can be moved as a whole to the target area for display, thereby ensuring that the target object can be displayed in the target area of ​​the shooting preview interface.

[0083] In addition, in some possible implementations, when there are multiple target cameras, S130 may specifically include:

[0084] Based on each camera in the target camera, the image displayed on the second shooting preview interface is subjected to horizon correction processing to obtain a correctable area in the correction shooting preview interface corresponding to each camera;

[0085] Determine a third camera from the target cameras according to the area of ​​the correctable region;

[0086] Shooting is performed based on the correction shooting preview interface corresponding to the third camera to obtain a target image.

[0087] Here, when there are multiple target cameras, the size of the correctable area in the correction shooting preview interface corresponding to different target cameras may be different. Therefore, the camera with the best field of view angle can be selected for shooting based on the effective area of ​​the correctable area determined by each target camera.

[0088] For example, after determining the target object for tracking focus, it can be determined whether to take a photo. In the process of determining whether to take a photo, the camera with the best correction effect is selected from the multiple optional target cameras through the horizon correction recognition algorithm, that is, the third camera, as the camera used for the final photo. Among them, the basic principle of the horizon correction recognition algorithm can be to identify the effective area of ​​the correctable area displayed in the correction shooting preview interface.

[0089] Based on this, the step of determining the third camera from the target cameras according to the area of ​​the correctable area may specifically include:

[0090] The camera with the largest correctable area among the target cameras is determined as the third camera.

[0091] Here, the larger the area of ​​the correctable region is, the higher the probability of successfully correcting and identifying the target object is, and the better the correction effect is. Therefore, the camera with the largest area of ​​the correctable region can be determined as the camera finally used.

[0092] In this way, by determining the third camera to be used for the final shooting based on the area of ​​the correctable area in the correction shooting preview interface during the final shooting process, the identified camera with the optimal field of view can be used for horizon correction processing and the final shooting process, thereby further improving the correction effect and the success rate of correction.

[0106] A difference acquisition submodule, used for acquiring difference information between the display area and the target area before switching the first camera for capturing the target object in the electronic device to the second camera;

[0107] A target determination submodule is used to determine, based on the difference information, a target camera whose field of view matches the target object from among the multiple cameras, wherein the target camera includes the second camera.

[0108] In one embodiment, the first display module 902 may further include:

[0117] Therefore, by locking the target object selected by the user while the user is using the electronic device to take pictures, the content that the user wants to shoot, that is, the target object, is displayed in the target area of ​​the second shooting preview interface based on the images captured by multiple cameras in the electronic device, and then correction processing and shooting are performed based on the second shooting preview interface to obtain the target image. In this way, since the embodiment of the present application shoots the target object based on multiple field of view angle ranges corresponding to multiple cameras, even if the user slightly offsets the electronic device, the multi-camera shooting technology can be used to present the target object that the user wants to shoot in a fixed area of ​​the shooting preview interface, which makes it easier to correct and shoot the target object, thereby improving the correction effect during image shooting and enhancing the user's shooting experience.
