In the data source clipping interface, a user can cut and combine pictures or videos or process the pictures or videos by adding other elements such as background music, special effects, scenes and other materials so as to increase the richness of the pictures or videos. Referring to fig. 3, an interface schematic diagram of a data source clipping interface according to the embodiments of the present application is shown in fig. 3, where an area 310 is a data source display area, an area 320 is a user-imported picture or video displayed in the data source display area, a control 330 is a background setting interface triggering control, and when the user touches the control 330, the data source clipping interface may be switched to the background setting interface.

Optionally, the zoom level of the background picture may be preset by a developer, or may be set by the user.

Step 230, cropping the equally scaled background picture such that the width and height of the cropped background picture are equal to the width and height of the data source display area.

Step 240, setting the background of the data source according to the cropped background picture, wherein the data source refers to the material processed at the data source processing interface.

Alternatively, the cropped background picture may be directly set as the background of the data source, or the cropped background picture may be processed and set as the background of the data source.

In summary, in the background setting method according to the embodiment of the present application, when a background setting instruction is received, a background picture is obtained according to the background setting instruction, and the center of the background picture and the center of a data source display area in a data source processing interface are taken as references, so that the width and the height of the background picture after equal scaling are both greater than or equal to the width and the height of the data source display area, and the background picture after equal scaling is cropped, so that the width and the height of the background picture after cropping are equal to the width and the height of the data source display area, and the background of the data source is set according to the cropped background picture, so that when the data source is processed, the integrity of the display of the data source is ensured, and the data loss caused by the change of the data source is reduced.

In step 601, a data source is acquired, where the data source is at least one of a video and a picture.

Optionally, multiple pictures can be played in a combined mode in the data source clipping interface in a video mode, and a user can set the time length and the display mode of each picture in the picture clipping process, for example, multiple pictures can be displayed in the same data source display area.

Similarly, the user may also clip, sequence and splice the video, such as combining multiple video content to play in the same video, or clip different video, combine the desired segments, and so on.

Step 602, obtaining an aspect ratio of a data source display area and an aspect ratio of a data source, respectively.

The application program to which the data source clipping interface belongs can identify the width and the height of the data source display area and the width and the height of the data source respectively, so as to calculate the aspect ratio of the data source display area and the aspect ratio of the data source respectively, and compare the aspect ratios of the two.

In step 603, when the aspect ratio of the data source is different from the aspect ratio of the data source display area, scaling the data source to be equal in proportion to the width or height of the data source to meet the data source display area based on the center of the data source and the center of the data source display area in the data source processing interface, and the size of the picture of the data source is not larger than the size of the data source display area.

In the above process, the scaling operation of the data source is stopped when one of the height and the width of the data source is connected with the data source display area for the first time, so as to ensure that the data source can be completely displayed in the data display area.

Referring to fig. 7, a schematic diagram of scaling a data source in an equal proportion is shown in fig. 7, where a portion a in fig. 7 shows a schematic diagram of the data source before scaling, and a portion B in fig. 7 shows a schematic diagram of the data source after scaling, where a region 710 represents a data source display region, a region 720 represents a data source, and in a scaling process of the data source, it is required to keep a center of the data source aligned with a center of the data source display region all the time, for example, a point 730 in fig. 7, where the center of the data source coincides with a center of the data source display region, and when a width or height of the scaled data source is equal to a width or height of the data source display region, that is, the data source meets the data source display region, scaling of the data source is stopped.

The user may trigger the touch operation of the control through the background setting interface in the data source clipping interface, and open the background setting interface, where the background is set according to the received background setting instruction, and the process please refer to the related description in the embodiment shown in fig. 2, which is not described herein.

Step 604, when receiving the background setting instruction, obtaining a background picture according to the background setting instruction.

Optionally, when the data source is a video, obtaining the background picture according to the background setting instruction may be:

acquiring each picture frame in a data source;

and setting each picture frame as a background picture corresponding to each picture frame in the data source. The user may set the acquired background picture as a moving picture by touching a designated control in the background setting interface, for example, in the background setting interface shown in fig. 4, the user may set the background picture of the data source as a moving picture by touching a control 432 in the area 430.

Optionally, the data source is a picture, when the user combines a plurality of pictures into a form of an atlas for display, the picture frame of the data source changes with time in the display process, and the application program can acquire the picture change in the data source in real time and acquire the picture of each frame, and after processing the picture, the picture is used as the background picture of the data source of the corresponding frame.

When the data source is video, the video is a continuously played picture, and the playing process of the video is that of the picture frame, so that in the process of refreshing the video picture frame, an application program can acquire the picture of each frame in the video picture in real time, and the picture is processed and then is used as the background picture of the data source of the frame corresponding to the picture.

Optionally, when the picture content of n consecutive frames is the same frame, the application program may identify that the picture content of n consecutive frames is the same picture, so as to increase the interval time of collecting the picture frames, so as to reduce the waste of collecting the picture resources caused by collecting the picture frames when the picture content is unchanged all the time, where the value of n may be preset.

Optionally, when the data source is a picture, when receiving a background setting instruction, obtaining the background picture according to the background setting instruction may be:

As shown in fig. 4, in the area 430, a part of the still picture preset in the background setting interface is displayed, and the user selects the still picture as the background picture by performing a touch operation on the still picture in the area 430.

Optionally, the background setting interface further includes a control for linking the terminal picture storage file, the user performs touch operation on the control to enter the picture storage file in the terminal, and selects the region in the storage file as the background picture by selecting the picture in the storage file, for example, in the background setting interface shown in fig. 4, the user may open the picture storage file in the terminal by touch operation on the control 431, so as to select the picture in the file as the background picture.

Optionally, the picture of a certain frame picture in the data source can be designated or randomly acquired as the background picture of the data source, that is, the picture of the frame picture is always taken as the background picture in the process of playing the data source.

And step 605, scaling the background picture in equal proportion by taking the center of the background picture and the center of a data source display area in the data source processing interface as references, so that the width and the height of the background picture after the equal proportion scaling are larger than or equal to the width and the height of the data source display area, wherein the data source display area is a data source preview area in the data source processing interface.

Step 606, cropping the equally scaled background picture such that the width and height of the cropped background picture are equal to the width and height of the data source display area.

The implementation manners of step 605 to step 606 may refer to the implementation manners of step 220 to step 230 in the embodiment shown in fig. 2, and will not be described herein.

In step 607, the background of the data source is set according to the cropped background picture, where the data source refers to the material processed at the data source processing interface.

When the data source processing interface generates a data source with background setting, the application program firstly renders a background picture in the data source display area, and then superimposes and displays the data source with equal scale on the background picture so that the data source with equal scale is positioned at the uppermost part of the data source display area.

Alternatively, the cropped background picture may be directly set as the background of the data source.

And when the cut background picture is set as the background of the data source, rendering and displaying the cut background picture in a data source display area.

As shown in fig. 8, on the basis of fig. 4, a still picture indicated by the third control in the area 430 is selected as the background of the data source, and the still picture is directly set as the background of the data source after being cropped.

In one possible scenario, the still picture may be set directly as the background of the data source when the width and height of the still picture is exactly equal to the width and height of the data source display area.

Or, optionally, blurring the cut background picture;

and setting the blurred background picture as the background of the data source.

Optionally, the blurring processing of the cropped background picture may be performed by gaussian blurring processing.

And when the background picture after the blurring processing is set as the background of the data source, rendering and displaying the background picture after the blurring processing in a data source display area.

And superposing and displaying the data source after the equal scaling on the background picture after the blurring processing.

Fig. 9 is a schematic diagram showing setting a background picture after blurring processing as a data source background according to an embodiment of the present application. As shown in fig. 9, on the basis of fig. 4, a dynamic picture indicated by a control 432 in an area 430 is selected as a background of a data source, and the dynamic picture is blurred and then set as the background of the data source.

Optionally, a control for adjusting transparency of the background picture is arranged in the background setting interface, and a user can adjust transparency of the background picture through specified operation of the control, so that the background picture and the data source are more coordinated.

Optionally, after setting the background of the data source according to the cropped background picture, the method further includes:

and publishing the data source with the set background to a playing platform corresponding to the application program.
