In addition, in this application, the mobile terminal has a first camera and a second camera. The first camera and the second camera are located on the same plane, for example, on the back of the mobile terminal at the same time. However, which camera is the first camera and which camera is the second camera is not limited in this application, and for example, the mobile terminal has A, B two cameras, and a may be the first camera and B may be the second camera, or a may be the second camera and B may be the first camera.
The method specifically comprises the following steps:
in the embodiment of the invention, the user can enter the shooting mode through the entity key of the mobile terminal and also can enter the shooting mode through the application program of the mobile terminal. The mobile terminal has other shooting modes besides the dynamic image shooting mode, and after the mobile terminal enters the shooting mode, the user can select the dynamic image shooting mode. Of course, the user may also set that the mobile terminal can directly enter the dynamic image shooting mode.
When the mobile terminal is in the dynamic image shooting mode, the user can shoot through a physical button of the mobile terminal, such as a shooting button, or through a virtual button, such as a shooting button on a screen.
After the user presses the shooting button, the central processing unit of the mobile terminal can simultaneously send a shooting instruction to the first camera and the second camera, the first camera can shoot a first image after receiving the shooting instruction, the second camera can shoot a plurality of second images after receiving the shooting instruction, and as for the number of the second images, the user can set the number of the second images by himself according to the requirements, for example, 10 or 20 images can be selected. In addition, the order of shooting by the first camera and the second camera may be that the first camera shoots first, and the second camera shoots second after shooting is completed, or the first camera and the second camera shoot simultaneously, or the second camera shoots first, and the first camera shoots second after shooting is completed, which is not limited in the embodiment of the present invention.
In a preferred embodiment of the present invention, when the mobile terminal enters a dynamic image capturing mode, the first camera captures a plurality of images;
and taking any one of the plurality of images as a first image.
Specifically, the number of shots taken by the first camera may be the same as the number of shots taken by the second camera, in this case, the first camera and the second camera take shots simultaneously, and after the shooting is completed, one image is selected from the multiple shot images as the first image; the number of the first camera and the number of the second camera may be different, and only one of the plurality of images shot by the first camera is reserved, so that the first camera may not need to shoot so many images, in this case, the order of the first camera and the second camera may be that the first camera shoots first and the second camera shoots second after shooting is completed, or that the first camera and the second camera shoot simultaneously, or that the second camera shoots first and the first camera shoots second after shooting is completed.
Certainly, the user can also manually shoot a plurality of second images, when the mobile terminal is in a dynamic image shooting mode, the user presses the shooting button for the first time, the first camera shoots the first image, the second camera shoots the second image at the same time, the user presses the shooting button for the second time, the first camera does not shoot, the second camera continues to shoot the second image, and so on; the user may also press the shooting button each time, the first camera and the second camera perform shooting at the same time, after the shooting is completed, one image is selected from the multiple images shot by the first camera as the first image, and which image is selected as the first image may be selected by the central processing unit or manually selected by the user, which is not limited in the embodiment of the present invention.
because the mobile terminal is provided with two cameras which are positioned on the same plane and have a certain distance, the two cameras and the shot object form a triangle, so that the depth of field of the first image and the depth of field of the second image can be calculated through the triangle, and then the main body area and the background area in the first image and the main body area and the background area in the second image are determined according to the depth of field.
103, overlapping the layer corresponding to the first main body area with the layer corresponding to the second background area in each second image respectively to generate a plurality of third images;
specifically, after the first body region in the first image is determined, images other than the body region need to be removed, for example, the first body region can be scratched from the first image in a scratching manner, so that an image layer including the first body region is obtained, and the region in the image layer other than the first body region is transparent; correspondingly, the layer of each second image including the second background area may also be obtained in the same manner, and the area in the layer except for the second background area is also transparent. And then, overlapping the image layer containing the first main body area with a plurality of image layers containing the second background area respectively to generate a plurality of third images. For example, there are 1 layer including the first main area, 20 layers including the second background area, and the layer including the first main area is superimposed with the 20 layers including the second background area, respectively, to generate 20 third images.
And 104, generating a first dynamic image by adopting the plurality of third images.
In a preferred embodiment of the present invention, the step of generating the first moving image using the plurality of third images includes:
setting the playing time interval information of each third image;
and storing the playing time interval information and the plurality of third images as a first dynamic image.
Since the moving picture is a group of specific still pictures switched at a specific frequency, after a plurality of third pictures exist, the playing time interval of each third picture needs to be set, for example, the setting time interval is 0.5 seconds, which means that the switching is performed after the first third picture is displayed for 0.5 seconds, the second third picture is displayed, and so on. After the setting is finished, the plurality of third images and the playing time interval information are stored in a file in a GIF format to generate a first dynamic image.
In the embodiment of the invention, when the mobile terminal is in a dynamic image shooting mode, a user presses a shooting button, a first camera collects a first image, a second camera collects a plurality of second images, then a first main body area is obtained from the first image, a second background area is obtained from the plurality of second images, then the image layer containing the first main body area is superposed with the plurality of image layers containing the second background area respectively to generate a plurality of third images, then the playing time interval information of each third image is set, and finally the plurality of third images and the playing time interval information are stored as the first dynamic image. Therefore, when a user uses the mobile terminal to shoot a photo, the dynamic image can be generated without special dynamic image making software or a network, the operation is simple and quick, and the user experience is improved.

and taking any one of the plurality of images as a first image.
specifically, after the first background area in the first image is determined, the image outside the main body area needs to be removed, for example, the first background area can be scratched from the first image in a scratching mode, so that an image layer containing the first background area is obtained, and the area in the image layer except the first background area is transparent; correspondingly, a layer of each second image including the second main body region may also be obtained in the same manner, and regions in the layer other than the second main body region are also transparent. And then, overlapping the image layer containing the first background area with a plurality of image layers containing the second main body area respectively to generate a plurality of fourth images. For example, there are 1 layer including the first background region, 20 layers including the second main body region, and the layer including the first background region is superimposed with the 20 layers including the second main body region, respectively, to generate 20 fourth images.
And step 204, generating a second dynamic image by using the plurality of fourth images.
