In this embodiment, the image processing method may be applied to the mobile terminal shown in fig. 1 or fig. 2, and it is understood that the image processing method may also be applied to electronic devices such as a tablet, an electronic book, and the like. The image processing method comprises the following steps:
step S310, determining a background image;
step S320, acquiring a continuously acquired video image;
and S330, synthesizing the acquired video image and the background image in real time to obtain a target video.
Through the embodiment, after the image acquisition application program is started, the background image is determined in the unified graphical user interface provided by the application program, the background image is displayed through the image preview interface of the application program, the video image continuously acquired by the image acquisition device is controlled by receiving the video acquisition instruction in the current graphical user interface, then the target video is obtained by real-time synthesis according to the acquired video image and the background image, and the real-time synthesized target video is displayed on the image preview interface, so that a user can know the currently synthesized target video in real time.
The above steps will be specifically described with reference to specific examples.
In step S310, a background image is determined.
Specifically, the background image includes at least one of: at least one background static picture; and a background video image. The background still picture refers to a still picture, which may be one or more, and is not particularly limited. A background video image refers to a segment of a video file. The background image may be an image that has been shot previously, or may be an image that is temporarily captured in the current state.

step S3101, providing an image preview interface and a first interactive control through a graphical user interface;
step S3102, determining the background image in response to the touch operation for the first interactive control.
Specifically, the method and the device can realize the synthesis with the background image while acquiring the video image through a single application program, and avoid the complicated flow caused by the separate operation of the steps of acquiring the video and synthesizing the background image in the prior art. In step S3101, the gui is an exchange interface provided by the mobile terminal, and the image preview interface is an interface provided by the present application for displaying the synthesized video image in real time, for example, if the image processing function provided by the present application is provided by a camera application of the mobile terminal, the image preview interface is a preview interface after the camera application is started, and the content displayed in the preview interface is an image acquired by an image acquisition device of the mobile terminal. It should be noted that one of the important points of the present application lies in the selection of the background image and the subsequent acquisition of the video image, which can be displayed in real time through the image preview interface.
The first interactive control can be a specific position of the setting and image preview interface, so that a user can set a background image on the current interactive interface without switching to other application programs.
In an alternative embodiment, step S3102 may include the steps of:
step S31021, displaying a material selection interface including an existing picture or video in the material selection interface in response to the touch operation of the first interactive control;
step S31022, responding to the selection operation on the material selection interface, and according to the target picture or video corresponding to the selection operation;
step S31023, the target picture or video is determined to be a background image.
Specifically, through the above embodiment, the user can select the background image from the pictures or videos already saved in the mobile terminal. In this embodiment, the touch operation of the first interactive control is a click operation, a slide operation, or other operations that can trigger the first interactive control. The material selection interface can be overlapped in the current image preview interface in a pop-up window mode, and thumbnails generated according to pictures or videos stored in the mobile terminal are displayed in the material selection interface. Through the embodiment, the user can select the image which is required to be used as the background from the saved pictures or videos before the video image is acquired.
In an alternative embodiment, step S3102 may include the steps of:
step S31024, in response to the touch operation for the first interactive control, acquiring an image through an image acquisition device, wherein the image may be a picture or a video;
in step S31025, the captured image is determined as the background image.

In step S330, a real-time synthesis is performed according to the captured video image and the background image to obtain a target video.
Specifically, the video recording process comprises video decoding, the decoded video is sent to a video superposition module, the video collected by a camera and a background image are synthesized by the video superposition module, the synthesized data are respectively drawn to a screen area to be displayed in real time, and meanwhile, the synthesized data are sent to an encoder to generate a video file. In an alternative embodiment, step S330 may include the following steps:
step S3301, displaying the background image through the image preview interface;
s3302, synthesizing the video image collected in real time with the background image to obtain target video data;
and step S3303, drawing the target video data to the image preview interface to display the target video in real time.
Specifically, in a specific implementation, the background image and the acquired video image are respectively drawn into a screen in a process of synthesizing, a current synthesized video effect is displayed through an image preview interface, and simultaneously, synthesized video data is sent to an encoder to generate a target video file in real time.
Through the implementation mode, the user can record the video and display the video effect synthesized with the self-defined background image in an interactive interface or a flow, and simultaneously, the synthesized video can be generated when the video recording is finished.
Further, the method provided by the present application further includes:
and responding to the selection operation of the superposition mode, and determining the superposition mode of the background image and the video image. The superposition mode refers to a pixel superposition mode of a background image and a video screen image frame.

Wherein, the superposition mode comprises at least the following modes: transparency stacking, bright portion stacking, dark portion stacking, and top-bottom stacking. Specifically, the transparency overlap is obtained by performing weighted average on the video image and the background image according to the transparency selected by the user to obtain an overlapped image. And (3) bright part superposition: and comparing the pixels of the video image and the background image one by one, reserving brighter pixels, and forming a superposed image by the pixels. Dark part superposition: and comparing pixels of the video image and the background image one by one, reserving darker pixels, and forming a superposed image by the pixels. And (3) stacking up and down: the upper half or lower half of the video image and the lower half or upper half of the background image are used to form the overlay image, as selected by the user.
Through the embodiment, the user determines the composite effect in advance before the mobile terminal collects the video image, and then the video image and the background image are directly composited according to the composite mode determined by the user in the video collecting process and are displayed through the image preview interface.
