The switching duration of each picture is the duration required to switch from that picture to the next frame of picture. The playing time of each picture is the time required for playing one picture. A picture can be understood as a frame. The first accumulation time corresponding to each picture is the time of recording the switching process in the process of switching the picture to the picture of the next frame of the picture, for example, when one picture starts to be switched, the first accumulation time is zero, the switching process of one picture is just completed, and the first accumulation time is the switching time of the picture.

If the first accumulation time is the switching time of the picture, the switching from the picture to the next frame of picture of the picture is completed, and after the switching is completed, the next frame of picture of the current frame of picture can be started to be played. If the first accumulation time is not equal to the switching duration, the switching is not completed, so that the picture is continuously switched until the first accumulation time is equal to the switching duration. For example, the current frame picture is picture a, the next frame picture of the current frame picture is picture B, and when the switching from picture a to picture B is completed, the playing of picture B is started.

And when the second accumulation time is equal to the playing duration, indicating that the playing of the picture is completed, and starting to switch the picture to the next frame of picture of the picture. And when the second accumulation time is not equal to the playing duration, indicating that the picture is not played, and continuing playing the picture. For example, the current frame picture is picture B, the next frame picture of the current frame picture is picture C, and when playing of picture B is completed, switching of picture B to picture C is started.
The present embodiment and the previous embodiment can be understood as one cycle in practice, for example, there are a picture a, a picture B, and a picture C. The next frame picture of picture a is picture B and the next frame picture of picture B is picture C. After the picture A is played, switching from the picture A to the picture B is started, and when the switching from the picture A to the picture B is completed, playing the picture B is started; when playing the picture B is completed, starting to switch the picture B to the picture C; and switching the picture B to the picture C to finish, starting to play the picture C … … if the picture C does not have the picture of the next frame, indicating that the target visual angle playing is finished, and continuing to switch the picture C to the picture of the next frame if the picture C exists.

Optionally, the playing module 404 is further configured to obtain a switching duration of each picture in the target view and a playing duration of each picture; and playing the target visual angle according to the first accumulation time corresponding to each picture, the switching time of each picture, the second accumulation time corresponding to each picture and the playing time of each picture.
The switching duration of each picture is the duration required to switch from that picture to the next frame of picture. The playing time of each picture is the time required for playing one picture. A picture can be understood as a frame. The first accumulation time corresponding to each picture is the time of recording the switching process in the process of switching the picture to the picture of the next frame of the picture, for example, when one picture starts to be switched, the first accumulation time is zero, the switching process of one picture is just completed, and the first accumulation time is the switching time of the picture. The second accumulation time corresponding to each picture is the time of recording the playing process in the process of playing the picture, for example, when one picture starts to be played, the second accumulation time is zero, the playing of one picture is just completed, and the second accumulation time is the playing duration of the picture.
Optionally, the playing module 404 is further configured to complete switching from the current frame picture to the next frame picture of the current frame picture according to the first accumulation time corresponding to the current frame picture and the switching duration of the current frame picture, including: updating the first accumulation time corresponding to the current frame picture in real time, and starting to play the next frame picture of the current frame picture when the first accumulation time corresponding to the current frame picture is equal to the switching duration corresponding to the current frame picture.
When a picture starts to be switched, the first accumulation time is zero, the picture switching process is just completed, and the first accumulation time is the switching duration of the picture. If the first accumulation time is the switching time of the picture, the switching from the picture to the next frame of picture of the picture is completed, and after the switching is completed, the next frame of picture of the current frame of picture can be started to be played. If the first accumulation time is not equal to the switching duration, the switching is not completed, so that the picture is continuously switched until the first accumulation time is equal to the switching duration. For example, the current frame picture is picture a, the next frame picture of the current frame picture is picture B, and when the switching from picture a to picture B is completed, the playing of picture B is started.
Optionally, the playing module 404 is further configured to complete playing of the current frame picture according to the second accumulation time corresponding to the current frame picture and the playing duration of the current frame picture, including: and updating the second accumulation time corresponding to the current frame picture in real time, and starting switching from the current frame picture to the next frame picture of the current frame picture when the second accumulation time corresponding to the current frame picture is equal to the playing time corresponding to the current frame picture.
When one picture starts to be played, the second accumulation time is zero, the playing of the one picture is just completed, and the second accumulation time is the playing duration of the picture. And when the second accumulation time is equal to the playing duration, indicating that the playing of the picture is completed, and starting to switch the picture to the next frame of picture of the picture. And when the second accumulation time is not equal to the playing duration, indicating that the picture is not played, and continuing playing the picture. For example, the current frame picture is picture B, the next frame picture of the current frame picture is picture C, and when playing of picture B is completed, switching of picture B to picture C is started.
The present embodiment and the previous embodiment can be understood as one cycle in practice, for example, there are a picture a, a picture B, and a picture C. The next frame picture of picture a is picture B and the next frame picture of picture B is picture C. After the picture A is played, switching from the picture A to the picture B is started, and when the switching from the picture A to the picture B is completed, playing the picture B is started; when playing the picture B is completed, starting to switch the picture B to the picture C; and switching the picture B to the picture C to finish, starting to play the picture C … … if the picture C does not have the picture of the next frame, indicating that the target visual angle playing is finished, and continuing to switch the picture C to the picture of the next frame if the picture C exists.
