Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described 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, of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
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 is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The shooting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart of a shooting method according to an embodiment of the present disclosure, and as shown in fig. 1, the shooting method includes the following steps:
step 101: determining a target shooting object and a target shooting object in a target display area corresponding to the target shooting object;
in the embodiment of the application, when a user takes a video, since a target shooting object in a video to be shot needs to be always kept at the same position of the video, the target shooting object in the target video, which needs to be fixed at the same position, needs to be determined first, and certainly, a shooting scene needs to be determined, so that the target shooting object is in the shooting scene. Specifically, for example, when a user needs to take a video and ensures that a target shooting object is continuously and centrally displayed in the middle of the screen, the camera may be turned on, and a shooting mode of "focusing a shooting object" is selected, at which time the user moves the camera so that the target shooting object is located in the middle of a shooting picture of the camera, so that the target shooting object may be automatically identified and determined. Of course, other ways of determining the target photographic subject may be adopted, and the discussion will be made in other embodiments of the present application.
Step 102: synthesizing a first video image of a target shooting object and a second video image of a target shooting scene according to the target display area to obtain a target video, wherein the first video image is obtained by shooting through a first camera of the electronic equipment, and the second video image is obtained by shooting through a second camera of the electronic equipment; the first focal length of the first camera is greater than the second focal length of the second camera.
After the target shooting object and the target display area are determined, the first camera can be used for shooting the target shooting object to obtain a first video image of the target shooting object, the second camera can be used for shooting the shooting scene to obtain a second video image, and the target shooting object is a key object of video shooting, so that the first camera can be set as a long-focus camera in order to better shoot the details of the target shooting object, the shooting scene needs a wider viewing angle, and the shooting scene is provided for the target shooting object, so that the second camera can be set as a short-focus camera, the background zooming-in or zooming-out operation can be conveniently performed on the shooting scene, and different second video images can be obtained.
After the first video image and the second video image are obtained, the first video image and the second video image may be fused. It should be noted here that, for example, a user takes a video with a length of 10 seconds, and sets a frame of 30 frames per second, so that 300 fused images are required to obtain a final video.
In an embodiment of the present application, image fusion may be performed every 1/30 second, that is, image fusion is performed synchronously each time a first video image and a second video image at the same time are acquired, so as to obtain a current fusion image, and the current fusion image is displayed on a display screen of a camera.
Of course, in another embodiment of the present application, the image fusion may be performed at every preset time, for example, every 1 second, so that a total of 30 fused images need to be generated in a second. It is needless to say that the image fusion and the video generation may be performed when the user confirms that the shooting is finished, for example, the user shoots a video with a length of 10 seconds, a 30-frame picture is set every second, and 300 first video images and 300 second video images coexist at the time of the shooting, and at this time, the first video image and the second video image at the same time may be fused to obtain 300 fused images. So that the target video can be output based on the plurality of fused images.
After the fused images are obtained, the captured video file can be obtained by using the fused images. Specifically, the multiple fused images may be sequenced according to the time sequence of the timestamps corresponding to the multiple fused images when the images are fused to obtain a fused image sequence; and sequentially storing the images in the fusion image sequence as video frames to obtain a video file. Of course, in an embodiment of the present application, after each fused image is obtained, the fused image may be stored as a video frame of the video file.
Further, in one embodiment of the present application, a first input of a user may be first received in order to determine a target photographic subject; displaying a preview image of at least one object to be selected in response to the first input; and determining the target shooting object in the at least one object to be selected. That is, the user needs to turn on the camera first and enter into the interface shown in fig. 2, and fig. 2 is one of the interface schematic diagrams provided by the embodiment of the present application and responding to the first input, and it can be seen that two people are identified in fig. 2, and the person enclosed by the current dashed line is the person on the right side, and if the click is determined at this time, the person on the right side is determined to be the target shooting object. If the click is switched at the moment, the broken line frame encloses the figure on the left side, and then the click is determined, so that the figure on the left side is determined as the target shooting object. Of course, in practice, more images of the object to be selected may be identified and displayed for selection by the user. Other selection methods can be used for selection, for example, a user can directly click on an image of an object to be selected as a target photographic object, so as to determine the image of the target photographic object.
It should be noted that in practice, not only one target photographic subject may be determined, but if the first camera includes more than one camera, each camera may be set to focus on one target photographic subject, so as to select a plurality of target photographic subjects, and select corresponding display positions for the plurality of target photographic subjects. Specifically, the following steps may be performed in order to determine the first video image in the image of the object to be selected: displaying a selection interface of the at least one object to be selected; receiving a second input of the user on the selection interface; in response to the second input, determining the target object corresponding to the second input in the at least one object to be selected.
Of course, the selection of the target shooting object may also be performed in a manner of manual frame selection by the user, and specifically, the camera may receive a third input of the frame selection of the first video image by the user; determining a first video image in response to the third input; the first video image is at least one of the images of the object to be selected, which is selected by the user in a frame mode. That is, after the user manually selects the target photographic object on the touch screen, the target photographic object in the selected area is automatically identified by the electronic device, and the determination of the target photographic object is completed.
After the determination of the target photographic object is completed, a target display position of the target photographic object on the photographic scene may be set, and specifically, a preset display area may be displayed on the second video image to a user; receiving a fourth input of the user in the preset display area; in response to the fourth input, determining a target display area of the target shooting object after the target shooting object is fused in the second video image; the target display area is one of the preset display areas. For example, as shown in fig. 3, fig. 3 is one of the interface diagrams provided by the embodiment of the present application and responding to the fourth input, it can be seen that the second video image is divided into four equal rectangular areas, which are currently in a state of 1 from 4, and the user can click on a selection button of any one of the areas, thereby completing the determination of the target display area. As shown in fig. 4, fig. 4 is a second schematic view of an interface responding to a fourth input provided by the embodiment of the present application, and it can be seen that the second video image is divided into six equal rectangular areas, which are currently in a state of 1 out of 6, and a user can click on a selection button of any one area, thereby completing the determination of the target display area. As shown in fig. 5, fig. 5 is a third schematic view of an interface responding to a fourth input provided by the embodiment of the present application, and it can be seen that the second video image is divided into 9 equal rectangular areas, which are currently in a state of 1 out of 9, and a user can click a selection button of any one area, thereby completing the determination of the target display area.
Of course, the user may also manually customize the target display area, as shown in fig. 6, where fig. 6 is a fourth schematic view of an interface provided in the embodiment of the present application and responding to the fifth input. The user manually defines the target display area, and certainly, the area manually defined by the user is not regular enough, so that the size and the moving position of the rectangular frame can be adjusted by the user, and finally the area of the shooting scene corresponding to the rectangular frame is determined to be the target display area. That is, receiving a fifth input by a user on the second video image; in response to the fifth input, determining a target presentation area; and the target display area is a user-defined area clicked or circled on the second video image by the user.
On the basis of the above embodiment, the target shooting object and the target display area are determined, and the first video image and the second video image can be subjected to image fusion to obtain a plurality of fusion images, specifically, the first video image and the second video image with the same timestamp can be subjected to image fusion; the first video image is positioned in a target display area of the second video image; the first video image is located above the second video image. In the process of image fusion, the first video image may be transformed, for example, the first video image may be adapted according to the size of the target display area and the fixed aspect ratio of the original first video image, and the target display area is filled;
specifically, for example, the target display area is a rectangular area with the dimensions: the height is 9 units, the width is 6 units, and the size of the first video image is 3 units, the width is 2 units, at this time, the height and the width of the first video image can be multiplied by 3, so that the target display area can be filled; if the size of the first video image is 3 units high and 1.5 units wide, the height and width of the first video image can be multiplied by 3 to obtain a transformed first video image with a size of 9 units high and 4.5 units wide, and the target display area cannot be filled. Of course, in another fusion method of the present application, it is possible to ensure that the first video image is displayed at the middle position of the target display area selected by the user by ensuring that the geometric center coordinates of the first video image and the target display area coincide.
On the basis of the above embodiment, the target video can be output based on the multiple fusion images subsequently obtained, and specifically, the first video image and the second video image with the same timestamp can be subjected to image fusion to obtain the fusion image; sequencing the multiple fusion images according to the time sequence of the timestamps corresponding to the fusion images to obtain a fusion image sequence; sequentially storing the images in the fusion image sequence as video frames of a target video to obtain the target video; wherein the first video image is located in a target display area of the second video image; the first video image is located above the second video image. . Of course, for a video file, not only a video frame of a frame but also a corresponding audio track file are generally included, and for the audio track file, the audio file can be generated by using a sound pick-up to synchronize while recording a video, and the audio file is synthesized into a final video file.
As shown in fig. 7 and 8, fig. 7 is one of the shooting interface diagrams of a shooting method according to the embodiment of the present application; fig. 8 is a second shooting interface diagram of a shooting method according to an embodiment of the present application; as can be seen from fig. 7, the target photographic subject (target person) is located at the middle position of the photographic scene 1, while as can be seen from fig. 8, when the photographic background is shifted to the photographic scene 2, the target photographic subject (target person) is still located at the middle position of the photographic scene 2. In particular practice, the shooting scene may be subjected to sliding zooming, thereby achieving centered display of the target photographic subject under the changed shooting scene.
As shown in fig. 9 and 10, fig. 9 is a third shooting interface diagram of a shooting method according to the embodiment of the present application; fig. 10 is a fourth view of a shooting interface of a shooting method according to an embodiment of the present disclosure; in fig. 9 and 10, there are two target photographic subjects (target persons), and accordingly, there should be two image capturing units in the first camera that focus on the two target photographic subjects, respectively, and the positions of the two target photographic subjects do not change with time in the changed photographic scene. Of course, for the target photographic subject, if the target photographic subject is a moving object, a target recognition and tracking algorithm may be used to track the target photographic subject and acquire an image of the target photographic subject (target person), so as to synthesize the target photographic subject into the photographic scene.
According to the shooting method provided by the embodiment of the application, the target shooting object can be determined, and the operation cost of adjusting the focal length to keep the shooting position is reduced; and the final effect is achieved without a picture synthesis mode in the follow-up process, so that the shooting cost of the videos is reduced.
