Each preview image selects an image in one of the regions as a background image for the preview image. After the video recording is completed, the videos are placed in the corresponding areas of the target image 300 and spliced into a third video. For example, if the image in the second area 302 of the first preview image selection target image 300 is used as the background image and the first area 301 of the second preview image selection target image 300 is used as the background image, after the recording is completed, the first video is placed in the second area 302 of the target image, the second video is placed in the first area 301 of the target image, and the third video is spliced. And finally, the multiple persons sing together differently, and the effect of presenting the effect that the multiple persons sing together in the same place is realized.

And the user adjusts the shooting magnification of the first terminal according to the prompt message until the adjusted first ratio and the second ratio are close enough, and if the image ratio adjustment is finished, as shown in fig. 4, the user determines that the image ratio adjustment is finished.
3. After the image occupation ratio is adjusted, the image occupation ratio is kept stable, and the display position of the first object is further adjusted, as shown in fig. 4, the distance y2 between the person frame of the second object and the corresponding upper boundary and the distance x2 between the person frame of the first object and the corresponding upper boundary and the distance y1 between the person frame of the first object and the corresponding left boundary and the distance x1 between the person frame of the first object and the corresponding upper boundary are acquired.
4. By comparing the display position of the first object and the display position of the second object, the display moves upward (y1-y2) and moves leftward (x1-x2) in the floating frame 102. The user adjusts the display position of the first object according to the prompt information until it is sufficiently close to the display position of the second object, as shown in fig. 8.
5. After the image proportion and the display position of the corresponding preview image of all other terminals are adjusted, the picture environment of the first preview image is adjusted to be consistent with the picture environment of the second preview image through the video filter function and the background switching function.

An example of adjusting the shooting parameters of the first preview image according to the second preview image is given based on a camera with a laser ranging function in the embodiment of the present application:
1. as shown in fig. 5, the cameras of the terminals having the laser ranging function are turned on, the second distance d2 of the second object and the first distance d1 of the first object are obtained, and the ratio of d2 to d1 is calculated, for example, 0.8 times, the current shooting magnification of the first terminal is multiplied by the ratio, so that the magnification to be switched is obtained, for example, if the current shooting magnification is 1X, the magnification to be switched is 1X 0.8X, and the display is switched to 0.8X in the suspension frame 102. The shooting magnification can be more accurately adjusted by combining the laser ranging function, and the shooting magnification can be quickly adjusted in place.
2. After the image occupation ratio is adjusted, as shown in fig. 6, the distance y2 from the corresponding upper boundary and the distance x2 from the left boundary of the person frame of the second object, and the distance y1 from the corresponding upper boundary and the distance x1 from the left boundary of the person frame of the first object are obtained.
3. The connecting line between the two points is calculated by placing (x1, y1) and (x2, y2) in the same coordinate system, and as shown in fig. 6, the connecting line is displayed in the first preview image as first adjustment information, prompting the user to move the first object in the direction of the connecting line, and finally, the display position of the first object is adjusted to be close to or the same as that of the second object.
4. After the image occupation ratios and the display positions of the preview images corresponding to all other terminals are adjusted, as shown in fig. 7, the target image is divided into a plurality of areas as a large background image, and each terminal selects an image in one of the areas as the background image corresponding to the preview image.
