In a kind of possible implementation, can be required for select user in step S1402 according to user's request
Two field picture.Specifically, the screen time is for example recorded for 5s, namely when a length of 5s of the video for obtaining is shielded in record, it is generally the case that from
75～100 two field pictures can be parsed in the video.Then, these two field pictures and may be not all what user wanted.There is mirror
In this, user can select two field picture, such as 30 two field pictures required for user from these two field pictures, then in above-mentioned step
Selected this 30 two field pictures are synthesized in rapid S1403, to produce the desired GIF figures of user for video,
In being then stored in corresponding memory.
In a kind of possible implementation, can be changing what is extracted in step S1402 according to user's request
Time interval between each two field picture.Specifically, in each two field picture for being extracted, timestamp is generally all carried, these
Timestamp can represent the time period that the two field picture shows in the GIF figures to be synthesized.For example, with each two field picture for being extracted
Content independently, the time interval between record each two field picture for obtaining of screen starts to be 2s, however exist user want it is longer
The demand of a certain two field picture interested of viewing of time.At this moment, can by the display duration of the two field picture arrange compared with
It is long, that is, change the two field picture and before or after two field picture between time interval.It is each that above-mentioned change is extracted
Time interval between two field picture can be realized by adjusting the timestamp of each two field picture.Then, in above-mentioned steps S1403
In, each two field picture synthesis after above-mentioned process will be carried out, to produce the desired GIF figures of user for video, so
After store in corresponding memory.So, when playing above-mentioned GIF figures on the display device, it is possible to achieve according to the need of user

In a kind of possible implementation, can be extracted with being changed in above-mentioned steps S1402 according to user's request
The DISPLAY ORDER of each two field picture for going out.Specifically, in some cases, adjust DISPLAY ORDER in GIF figures of each two field picture,
Such as backward shows can obtain more preferable display effect.Thus, in step S1402, can be needed according to user or real
The application scenarios on border record the DISPLAY ORDER of each two field picture that screen is obtained suitably to adjust.For example, if there are 10 frames in video
Image, then correspondingly after record screen obtain 10 two field pictures, generally this 10 two field pictures be positive sequence, for example according to from two field picture
The order of 1 to two field picture 10 is sequentially output.However, in order to obtain more preferable effect, in the present embodiment, display can be adjusted suitable
Sequence for example can be by being sequentially output from two field picture 10 to the backward of two field picture 1.Certainly, adjustment DISPLAY ORDER of the invention is not limited to
Backward is adjusted to, and the DISPLAY ORDER of these two field pictures can be arbitrarily adjusted according to the application scenarios of the demand of user or reality.
The DISPLAY ORDER of each two field picture that above-mentioned change record screen is obtained can be realized by changing the timestamp of each two field picture.So
Afterwards, in above-mentioned steps S1403, each two field picture synthesis after above-mentioned process will have been carried out, to produce the use for video
