The scene that the method for the special video effect switching first introducing the present embodiment may relate to, scene is general
It is divided into personage, indoor, street, scenery with hills and waters.Each scene can be divided into again prospect (main body shot in other words)
And background.
For the main body of different scenes, background does different special effect processing respectively.General object is prominent
Main body.As:
Personage's scene, main body is people, and people does U.S. face specially good effect；Background is done smoothing processing, prominent personage.
Indoor scene, main body is probably a desk, TV ... processing mode determines that the color of main body, to the back of the body
Scape does eclipsed process, only retains the color close with main body.
Street scene, main body is probably pedestrian, street lamp ... uses and moves axle specially good effect, and main body keeps clear, Xiang Si
Week gradually obscures.

The special effect processing difference used due to different scenes is very big, if directly changing specially good effect, picture easily goes out
The problems such as now flicker.
One, during video capture by the specially good effect handoff procedure of personage's scene to indoor scene as a example by, this regards
The method of specially good effect switching frequently, including following flow process:
One people, from being sitting in chair, leaves to standing up.When people is owing to leaning to one side or body leaves picture,
Scene is switched to indoor scene by personage's scene, at this moment can draw the frame of video of the setting number of frames after scene changes
Two kinds of process are done in face simultaneously: one is the process of original personage's scene, and one is the process of indoor scene.
Again by this two frame data superposition, the frame of video processed through personage's scene special effect before this accounts for big transparency proportion,
Then gradually decrease, until being switched to indoor scene completely.
Simultaneously as people leaves picture, when processing, just there is no main body by personage, but in order to the loftiest, also
It is to continue with for the frame of video picture setting number of frames, to main body last frame video pictures before scene changes
In the band of position continue to do U.S. face specially good effect, other parts do smoothing processing by background.
