Embodiment one:
Embodiment one method flow as shown in Figure 2, this embodiment imports the decoded multiframe static image data of video cartoon background paper into driver layer in the mode of filename to carry out special effect processing, it specifically comprises:
The processing of application layer
(11) selected video cartoon background paper of user.
(12) start the background guide that is located in the PC, be written into video cartoon background paper selected in the step (1).
(13) the video cartoon background paper that is written into is decoded by certain time interval, generate the multiframe static image data, be stored in document form data in the disk of PC, this time interval is used for the control to video cartoon background play frame rate.
(14) user freely chooses background special effect processing parameter for decoded multiframe static image data, these parameters comprise: the number of foreground, the R of each foreground, G, B value, the value of the alpha blending of each foreground (alpha mixing) vector, it is that a kind of two images of the alpha vector value with pixel color and this pixel color that make up simultaneously are to determine the last a kind of method that produces the mixed pixel color that alpha mixes; The user can also carry out special effect processing earlier with these multiframe static image datas, but be formed with the video cartoon background of the preview of special efficacy effect after selected these parameters; After the user confirms the background special efficacy effect of institute's preview, the fileinfo parameters such as filename that the notice driver layer receives background special effect processing parameter and is stored in the multiframe static image data in the PC.Also the time interval can be delivered to driver layer as parameter.

OriBlue: the B value of the source pixel that obtains from digital camera device;
BmpRed: the R value of the pixel of the foreground of importing into from background guide;
BmpGreen: the G value of the pixel of the foreground of importing into from background guide;
BmpBlue: the B value of the pixel of the foreground of importing into from background guide;
FrontColor[dwFrontColorIndex] .AlphaBlending): the value of the Alpha blending vector of dwFrontColorIndex foreground correspondence;
DwFrontColorIndex foreground carried out the R that following processing just obtains final blend color pixel, G, the B value:
OriRed＝{OriRed*(255-FrontColor[dwFrontColorIndex].AlphaBlending)+BmpRed*FrontColor[dwFrontColorIndex].AlphaBlending}/255；
OriGreen＝{OriGreen*(255-FrontColor[dwFrontColorIndex].AlphaBlending)+BmpGreen*FrontColor[dwFrontColorIndex].AlphaBlending}/255；
OriBlue＝{OriBlue*(255-FrontColor[dwFrontColorIndex].AlphaBlending)+BmpBlue*FrontColor[dwFrontColorIndex].AlphaBlending}/255。
