Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application are capable of operation in sequences other than those illustrated or described herein, and that the terms "first," "second," etc. are generally used in a generic sense and do not limit the number of terms, e.g., a first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.

The shooting method and the device thereof provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.

At present, as the frequency of shooting by using the electronic device by a user is higher and higher, the requirement on the shooting effect of the electronic device is also higher and higher. For example, in the process of shooting an image or video by a user, a horizontal line correction process is required, which may be a process of correcting an inclined line in order that a line actually parallel to a horizontal plane remains parallel to the horizontal plane in the shot image or video and a line actually perpendicular to the horizontal plane remains perpendicular to the horizontal plane in the shot image or video, in order to solve a problem that the line is inclined due to an inclined camera view angle in a picture captured by a camera.

However, in the existing horizon correction shooting mode, the electronic device always performs recognition correction based on the content collected by a single camera, and the recognition correction effect is poor due to the single field angle range.

Based on this, the present application provides a shooting method, which may be applied to correct a shooting scene, and the following describes in detail the shooting method provided in the embodiments of the present application with reference to fig. 1 to 8. In the shooting method provided by the embodiment of the present application, the execution subject may be a shooting device. In the embodiment of the present application, a shooting method executed by a shooting device is taken as an example, and the shooting method provided in the embodiment of the present application is described.

Fig. 1 is a schematic flowchart of a shooting method according to an embodiment of the present application.

As shown in fig. 1, the photographing method may include the steps of: s110 to S130, which will be described in detail below.

S110, receiving a first input of a target object displayed in a first shooting preview interface of the electronic equipment by a user.

The electronic device in the embodiment of the application may include a plurality of cameras, and the first shooting preview interface may be a preview interface displayed when shooting is performed by using one of the cameras.

In addition, the first input may be an input selected by the user on a target object displayed in the first shooting preview interface, where the input mode of the first input includes, but is not limited to, single click, double click, long press, and the like, and the target object includes, but is not limited to, a person, an object, and the like.

For example, after the user selects the target object to be photographed through the first input, the object locking frame may be displayed in the first photographing preview interface and disappear after a preset time period, so that the user may determine whether the selected target object is an object that the user wants to photograph.

In some specific examples, in a scene where a user uses a mobile phone to shoot an object, the user may enter a horizon correction mode by opening camera software in the mobile phone, and display a preview interface acquired by a camera of the mobile phone currently on a screen, that is, a first shooting preview interface. When a user faces a camera of the mobile phone to an object to be shot, the object to be shot can be displayed in the first shooting preview interface. As shown in fig. 2, if the user double-clicks the target object 21 displayed in the current preview interface, focus tracking recognition may be started, and after the target object 21 is recognized, the corresponding lock frame 22 may be displayed, and the target object 21 is locked. The lock box 22 may disappear after 3 seconds, but no focus chase is cancelled.

And S120, responding to the first input, and displaying the target object in a target area of a second shooting preview interface based on pictures acquired by a plurality of cameras of the electronic equipment.

Here, after the user selects the target object, the locked target object may be displayed in the target area of the second photographing preview interface through a preset focus-following algorithm and a plurality of cameras provided on the electronic device. The plurality of cameras may include any of a main camera, a 5X camera, a 2X camera, and a wide-angle camera, for example.

The position of the target area may be determined according to actual needs, and may be, for example, a central position area of the second shooting preview interface, or may be an area that facilitates correction processing, which is not limited herein.

For example, the present embodiment may select a camera having an optimal angle of view for the target object from a plurality of cameras provided on the electronic device according to a preset focus tracking algorithm, so that the target object can be displayed in a central position area of the shooting preview interface.

And S130, correcting and shooting the image displayed on the second shooting preview interface to obtain a target image.

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 the target image. The correction process may be, for example, a horizon correction process.

For example, the image information collected by the camera may be corrected in real time according to a preset horizon correction recognition algorithm, and then a correction shooting preview interface as shown in fig. 3 may be obtained, where the correction shooting preview interface may include a correctable area 31, and a preview picture after the horizon correction processing may be displayed in the correctable area 31.

In some embodiments, after obtaining the corrected shooting preview interface, the shooting method provided in the embodiments of the present application may further include:

receiving a second input of the user to the correction shooting preview interface;

and responding to the second input, and performing correction shooting based on the correction shooting preview interface to obtain a target image.

Here, the second input may be a shooting trigger input performed by the user based on a corrected shooting preview interface obtained after the horizon correction processing, and the input manner corresponding to the second input may include a manner of clicking a shooting button, or controlling shooting through a voice instruction, and the like.

In some examples, the user may click on a photo button in the rectification photographing preview interface shown in fig. 3, thereby obtaining an image displayed in the rectification area 31, i.e., a target image.

In this way, the target object which the user wants to shoot can be always kept in the target area by shooting the image based on the correction shooting preview interface after the final correction processing, and therefore the correction effect of the target object is improved.

Before S130, it may be determined whether object focus recognition needs to be performed again, and if so, the process returns to S120, and if not, the process returns to S130.

For example, if the user cancels the focus tracking, for example, clicks the focus tracking cancellation button in fig. 2, the camera may be restored to the default camera for shooting, and the zoom magnification, for example, 1-time zoom range, may be restored, and when the user reselects another object for focus tracking, the focus tracking state of the selected object may be triggered again.

Therefore, in the process of shooting by the user by using the electronic equipment, the target object selected by the user is locked, the content which the user wants to shoot, namely the target object, is displayed in the target area in the second shooting preview interface based on the pictures collected by the plurality of cameras in the electronic equipment, and further, correction processing and photographing are performed based on the second photographing preview interface to obtain a target image, and thus, since the embodiment of the present application photographs the target object based on the plurality of field angle ranges corresponding to the plurality of cameras, the target object is photographed, even if the electronic equipment is shifted by a small amplitude by the user, the target object which the user wants to shoot can be presented in the fixed area of the shooting preview interface by utilizing the multi-camera shooting technology, and then be convenient for correct the processing and shoot to the target object to correction effect when can improve the image and shoot promotes the user and shoots the experience.

Based on the foregoing S110 to S130, in some embodiments, as shown in fig. 4, the foregoing S120 may specifically include:

s1201, determining a display area corresponding to the target object in the first shooting preview interface;

s1202, under the condition that a display area is not matched with a target area, a first camera for collecting a target object in the electronic equipment is switched to a second camera;

and S1203, acquiring a target object through a second camera, and displaying the target object in a target area of a second shooting preview interface.

Here, the case of mismatch between the display area and the target area may include at least one of a location mismatch and a size mismatch.

For example, in a case that the display area does not match the target area, the camera in use, that is, the first camera, may be switched to adjust the field angle range, and then the target object may be photographed based on the corresponding field angle range of the switched camera, that is, the second camera, so that the target object is displayed in the target area of the second photographing preview interface, thereby achieving an effect that the display area corresponding to the target object matches the size of the target area.

In addition, after the target object is switched to the second camera, if the target object is 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 size of the display area corresponding to the target object is matched with that of the target area.

Therefore, under the condition that the display area corresponding to the target object is not matched with the target area, the first camera in use is switched to the second camera, the shooting view angle matched with the target object can be further obtained, the target object is displayed in the target area of the second shooting preview interface, and therefore the correction recognition success rate of the target object can be improved, and the correction effect is improved.

In addition, in some embodiments, 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:

acquiring difference information between a display area and a target area;

and according to the difference information, determining a target camera with the field angle matched with the target object from the plurality of cameras, wherein the target camera comprises a second camera.

Here, the difference information may include at least one of size difference information and location difference information. The number of the target cameras can be one or more, that is, one or more cameras with the view angles matched with the target object can exist, and then one camera is selected from the cameras randomly or according to a preset rule to serve as a second camera for final switching.

Therefore, the camera matched with the target object in the field angle is determined from the plurality of cameras according to the difference information between the display area and the target area, and then the second camera is determined to be switched, so that the camera suitable for the target object can be accurately found, the camera switching efficiency can be improved, and the camera suitable for the current shooting scene can be quickly positioned.

In some embodiments, the determining, according to the difference information, a target camera whose field angle matches the target object from among the multiple cameras, where the target camera includes a second camera, may specifically include:

determining a camera with a field angle smaller than that of the first camera from the plurality of cameras as a target camera under the condition that the display area is determined to be smaller than the target area according to the difference information;

and under the condition 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 value according to the difference information, determining a camera with a view angle larger than that of the first camera from the plurality of cameras as a target camera.

In some specific examples, if the camera currently in use is the main camera, as shown in fig. 5, when the focused target object 51 is recognized to be close, the display area 52 corresponding to the target object 51 is larger than the target area 53, so that the wide-angle camera with a larger field angle than the main camera can be automatically switched to according to the size difference information between the two, so as to obtain a better field angle; as shown in fig. 6, 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, so that the display area can be automatically switched to a 2X camera with a smaller field angle than the main camera or a 5X camera as shown in fig. 6 according to the size difference information between the two; as shown in fig. 7, if the mobile phone is shifted from the target object 71, the target object 71 may not be displayed completely in the preview picture captured by the current camera, that is, the position difference between the display area 72 corresponding to the target object 71 and the target area 73 is large, for example, the position shift amount of the display area 72 relative to the target area 73 exceeds a preset threshold, and then the mobile phone may automatically switch to the wide-angle camera with a larger field angle than the main camera according to the position difference information between the two.

As shown in fig. 6, when the user slightly moves the mobile phone, the 5X camera may be switched to a 2X camera, a main camera lens or a wide-angle lens to obtain a large field angle, and then the magnification is adjusted to display the focused target object on the camera preview interface in a centered manner.

In this way, by determining a camera whose field angle matches the target object from among the plurality of cameras according to the size difference or the position difference between the display area and the target area, it is possible to accurately find a camera suitable for the target object.

Based on this, in some embodiments, in a case that a position between the display area and the target area is not matched, the shooting method provided in the embodiment of the present application may further include:

acquiring a region image corresponding to a display region in a first shooting preview interface;

and displaying the area image in a target area of the second shooting preview interface.

For example, after the camera is switched, if the target object is not displayed in the target area of the second capture preview interface, the area image corresponding to the display area in the first capture preview interface may be cropped, and the cropped area image may be moved to the target area of the second capture preview interface, so that the target object is displayed in the target area.

In some specific examples, as shown in fig. 8, if the camera currently used by the mobile phone is a main camera, and for a case that the focused target object 81 is close and offset with respect to the mobile phone camera, the mobile phone may automatically switch to the wide-angle lens, and perform image cropping on the area 82 where the target object 81 is located, and further centrally display the area image in the area 82 in the shooting preview interface.

In this way, by image cropping, when the target object cannot be displayed in the target area even by shot cut, the entire area image corresponding to the target object is moved to the target area and displayed, and the target object can be surely displayed in the target area of the shooting preview interface.

In some possible embodiments, when the number of the target cameras is multiple, the S130 may specifically include:

performing horizontal line correction processing on the image displayed on the second shooting preview interface based on each camera in the target cameras to obtain a correctable area in the correction shooting preview interface corresponding to each camera;

determining a third camera from the target cameras according to the area of the correctable region;

and shooting based on the correction shooting preview interface corresponding to the third camera to obtain a target image.

Here, in the case where there are a plurality of target cameras, the sizes of the correctable regions in the correction shooting preview interface obtained based on correspondence between different target cameras may be different, and therefore, a camera with the best angle of view may be selected for shooting by the effective area of the correctable region determined for each target camera.

For example, after the target object of the focus tracking is determined, it may be judged whether or not to take a picture. In the process of judging whether to take a picture, a camera with the best correction effect, namely a third camera, is selected from a plurality of selectable target cameras through a horizon correction recognition algorithm and is used as a camera used in the final picture taking. The basic principle of the horizon correction identification algorithm can be to identify the effective area of a correctable area displayed in a correction shooting preview interface.

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

and determining the camera with the largest area of the correctable region in the target camera as a third camera.

Here, the larger the correctable area is, the higher the probability of successful correction recognition of the target object is, and the better the correction effect is, so that the camera corresponding to the maximum correctable area can be determined as the camera to be finally used.

In this way, in the final shooting process, the third camera used in the final shooting is determined based on the area of the correctable area in the correction shooting preview interface, so that the identified camera with the optimal field angle can be used for the horizontal line correction processing and the final shooting process, and the correction effect and the correction success rate can be further improved.
