Referring to FIG. 1 , which is a flowchart of a method for a first embodiment of a photographing method according to an embodiment of the present invention, the method of the embodiment may be performed by a photographing device, and the device may be implemented by software and/or hardware. And generally can be integrated in the mobile terminal. As shown in FIG. 1, the photographing method includes:

S110. Control a fixed camera to take a picture of the photographed area to obtain a first image.

In life, we often encounter that we want to shoot a dynamic object in the photographing area with the shooting area as the background. However, the problem of shooting failure due to the moving of the moving subject always affects the shooting effect and the mood of shooting. For example, the user wants to shoot a butterfly against the background of a rose. When we shoot for the moon, the butterfly may fly away, and the rose and the butterfly cannot be photographed on a photo.

The embodiment of the invention creatively uses a dual camera to take a picture, and the two cameras respectively capture the shooting area and the dynamic focus object, and then combine the captured photos, so that the moving object can be conveniently associated with the desired background area. Presented on the same photo. The dynamic focus object may be a dynamic human, an animal, a plant, and other objects, for example, a running animal, a swaying flower, and a kite floating in the air, etc., which is not limited in this embodiment.

When the user takes a photo using the mobile terminal, the terminal screen simultaneously displays a preview or shooting page of the two cameras. The preview or the shooting page of the two cameras can be divided into the terminal screens, or displayed in a small window, which is not limited in this embodiment.

First, a fixed camera is used to take a picture area, which is the background area that the user wants to take, usually a still area. For example, it can be a piece of grass, a picture, or a person posing. Even if there are a few movements, the movement is not very large. So you can shoot with a fixed camera. The fixed camera in this embodiment refers to a camera that is fixed in position and cannot be rotated. The first image is an image captured by a fixed camera, and generally only needs to take a first image. Of course, a fixed camera can also take multiple first images.

S120. Control a dynamic camera to perform tracking shooting on the dynamic focus object of the photographing area to obtain a second image.

The second image is an image captured by a dynamic camera, the dynamic camera is used for tracking and shooting a dynamic focus object, the mobile terminal senses a dynamic focus object in the camera through a dynamic camera, and then controls the dynamic camera to track the dynamic focus object, that is, The camera moves as the dynamic focus object moves.

There are two ways to take pictures. The first type, when the user presses the shooting button to start taking a picture, the terminal can control the fixed camera to take a first image, and control the dynamic camera to continuously capture the dynamic focus object; During the preview, the dynamic camera is controlled to track the dynamic focus object, and the user presses the shooting button according to the tracking state of the dynamic camera, the fixed camera captures a first image, and the second image of the dynamic focus object when the dynamic camera captures the position, the second image Only one shot was taken.

The embodiment of the present invention focuses on the first mode, so that the dynamic camera continuously captures the dynamic focus object, and takes multiple photos for the user to select. If only one picture is taken, the position and shape of the dynamic focus object may not match the user. Expectations. Exemplarily, if a dynamic camera is used to capture a child in a running, and a plurality of captured children are in a blinking state and a closed eye state, the user only needs to select the child's blinking state to use. It is very convenient to shoot. If you only take one shot, it is possible that the child is in a closed-eye state and needs to retake the shot.

The dynamic camera includes: a dynamic camera moving along a preset track, or a rotatable dynamic camera. Referring to FIG. 2, FIG. 2 is a schematic structural diagram of a terminal according to a first embodiment of a photographing method according to an embodiment of the present invention. The dynamic camera 11 follows the dynamic focus object movement along the preset track 12 in the horizontal direction, and the fixed camera 13 is used to capture the user-selected shooting area. It should be noted that the preset track 12 may be in the terminal width direction, or may be in the terminal length direction, or other preset directions. FIG. 2 is only a specific example of the preset track 12 in the terminal width direction.

The dynamic camera can also be rotatable. Such a dynamic camera is fixed in position but can be rotated in any direction for flexibility. If the dynamic focus object moves not only in the horizontal direction, for example, the bird will move up. The rotatable dynamic camera makes it easier to track dynamic focus objects.

S130. Splicing the first image and the second image to obtain a photo.

After acquiring the first image and the second image, the mobile terminal splices it to obtain a photo in which the dynamic focus object and the shooting area are presented together.

It is worth noting that the second image may have multiple photos, and the terminal may present the multiple photos for the user to select, or set the terminal to automatically select. You can select one of the photos to be spliced with the first image, or you can select multiple photos to be spliced with the first image to get the photos you want.

In summary, the camera is photographed by controlling the fixed camera to obtain a first image, and the dynamic camera is controlled to perform tracking shooting on the dynamic focus object of the photographing area to obtain a second image, and then the first image and the second image are stitched and combined. Get the photo. The program captures the dynamic focus object by using the dynamic camera while shooting the photographing area, and can display the dynamic focus object and the still photographed area of the photograph on the same photo, which increases the fun of photographing and improves the user experience.

Please refer to FIG. 3 , which is a flowchart of a method for the second embodiment of the photographing method according to the embodiment of the present invention. The embodiment of the present invention performs the stitching of the first image and the second image on the basis of the first embodiment. Detailed. In this embodiment, the first image includes a photo, and the second image includes a plurality of photos. As shown in FIG. 3, the photographing method includes:

S210. The focused object detected by the fixed camera is in a moving state.

Before taking a dual camera, first start the dual camera mode. In order to adapt to the different needs of users. "Dual camera photo mode", "fixed camera photo mode" and "dynamic camera photo mode" can be set in the application. Users can customize the selection. For example, if the user only shoots a plant, you can use the “fixed camera photo mode” to open only the fixed camera for shooting; if the user does not limit the background, only one walking kitten can be used, then “dynamic camera” can be used. Photo mode", only the dynamic camera is turned on for shooting.

Alternatively, the dual camera photographing mode may be assisted by the mobile terminal according to the state of the focused object of the photographing area. After the mobile terminal turns on the camera function, the camera is only turned on by the fixed camera for shooting. The mobile terminal controls the fixed camera to focus on the object to be shot. If the focus object of the shooting area is detected to be in motion, the camera is prompted to turn on the dual camera mode. When the focus object to the shooting area is not in motion, shooting is performed only by fixing the camera, that is, using the "fixed camera shooting mode".

S220: Output whether the prompt information of the dual camera photographing mode is turned on.

If it is detected that the focused object of the shooting area is in motion, output whether to prompt the dual camera shooting mode prompt information, and provide "Yes" and "No" options for the user to select; or output "dual camera shooting mode", " There are three modes: fixed camera shooting mode and dynamic camera shooting mode for users to choose.

S230. Receive an input instruction for turning on the dual camera photographing mode.

When the user chooses to turn on the dual camera photo mode, click the button to select. The terminal receives the instruction of the user to input the dual camera photographing mode, and turns on the dual camera photographing mode.

S240. Control the fixed camera to take a picture of the photographed area to obtain a first image.

S250. Control a dynamic camera to perform tracking shooting on the dynamic focus object of the photographing area to obtain a second image.

The dynamic camera can be controlled to track and shoot the dynamic focus object according to the time. For example, the dynamic camera can be set to capture every 0.5S, and the dynamic camera tracks the dynamic focus object 3S, so that the dynamic camera captures six photos.

In addition, the dynamic camera can also be controlled to intelligently track the dynamic focus object according to the pixel change. The above "smart" refers to the terminal automatically controlling the shooting of the dynamic camera according to the pixel change. Exemplarily, if the terminal detects that the image of the dynamic focus object previewed by the dynamic camera is different from the previous captured photo by 10 pixels, the dynamic camera is controlled to take a picture. Specifically, if the dynamic focus object is a running child, after controlling the dynamic camera to track 3S, it may take 10 photos; if the dynamic focus object is a walking elderly, control the dynamic camera to track it after 3S, possibly shooting 5 photos. Intelligent tracking shooting saves the operation of the terminal and saves the energy used for shooting.

S260. Select a photo from the plurality of photos of the second image, and splicing the first image with the selected one to obtain a still photo.

After the dynamic camera captures multiple photos of the second image, the terminal may select the last photo taken by the dynamic camera to be spliced with the first image to obtain a still photo. Alternatively, the first one can be selected, or the terminal can display all the captured photos for the user to select.

Illustratively, referring to FIG. 4 and FIG. 5, which are respectively a first photo view and a second photo view of a second embodiment of the photographing method provided by the embodiment of the present invention. When the group is photographed for the grandfather and the little boy, the mobile terminal controls the dynamic camera to take a picture of the little boy playing the plane. If FIG. 4 and FIG. 5 are the first and last photos of the captured little boy respectively, FIG. 6 is a photo of the grandfather photographed by the fixed camera, and if the mobile terminal selects the last photo in the second image of the little boy, The resulting static picture is shown in Figure 7.

In summary, by controlling the dynamic camera to continuously track the dynamic focus object, the terminal or the user selects a plurality of photos taken, and then splices the selected photo with the first image to dynamically focus the photographed area. The same shooting area is presented on a single photo, which enhances the user's shooting experience.

Please refer to FIG. 8 , which is a flowchart of a method for a third embodiment of a photographing method according to an embodiment of the present invention. The embodiment of the present invention performs splicing of a first image and a second image on the basis of the second embodiment. Detailed. Similarly, in this embodiment, the first image is a photo, and the second image includes a plurality of photos. As shown in FIG. 8, the photographing method includes:

S310. The fixed object detects that the focused object of the shooting area is in a motion state.

S320: Output whether the prompt information of the dual camera photographing mode is turned on.

S330. Receive an input instruction for turning on the dual camera photographing mode.

S340. Control the fixed camera to take a picture of the photographed area to obtain a first image.

S350. Control a dynamic camera to perform tracking shooting on the dynamic focus object of the photographing area to obtain a second image.

S360. Select a plurality of consecutive photos from the plurality of photos of the second image to create a dynamic picture, and splicing the first image with the dynamic picture to obtain a dynamic photo.

A plurality of consecutive photos may be selected from a plurality of photos of the second image to be made into a dynamic picture, and then spliced with the first image to obtain a dynamic photo for storage. Exemplarily, it can be made into a Graphics Interchange Format (GIF), that is, a plurality of consecutive photos are saved as one image file to form an animation. The completed animation can be used as a GIF animation for users to use in the live chat tool, which enhances the fun of taking pictures. Exemplarily, referring to Figures 4, 5 and 6, a small boy can be made from the beginning of throwing a paper plane to a paper plane, and then stitching with the grandfather's photo to complete the dynamic photo production.

In summary, by controlling the dynamic camera to continuously track the dynamic focus object, the terminal or the user selects several consecutive photos in a plurality of photos to create a motion picture, and then splicing with the first image to obtain the motion desired by the user. In the figure, while satisfying the user's requirements for the dynamic focus object and the fixed background photo, the acquisition of the animation enhances the interest of the photograph.
