The preset format is set according to the requirement, for example, the preset format may be a GIF format. The GIF format can store a plurality of images, and can constitute a simplest animation by reading out the plurality of images stored in one file one by one and displaying them on a screen. In this embodiment, a GIF-format emoticon image may be generated from the multi-frame image replacing the background pattern.
Therefore, according to the technical scheme, the user can generate the expression package in the preset format according to the appointed background picture selected by the user, and the expression package provided by a third party is not required to be passively received or selected, so that the effect of the expression package required by the user is obtained, and the use experience of the user is enhanced.
In one embodiment of the present invention, the selecting a plurality of frames of images from the video in step S110 includes: selecting a plurality of frames of images from the recorded video; or, in the process of recording the video, the multi-frame image is selected from the acquired video images while the video images are acquired.
The present embodiment is a preferred embodiment of the timing of extracting a plurality of frame images. The video in step S110 may be recorded by the user, so that when the emoticon image in the preset format is generated, the portrait in the video recorded by the user may be used, and the user experience may be further improved.
In this embodiment, the extraction of the multiple frames of images may be after the video is recorded, or during the process of recording the video. For example, a user records a video, and if the user wants to generate an expression package picture in the GIF format, the user can select to generate the expression package picture in the GIF format after the recording is completed, and then select a plurality of frames of images from the recorded video.
