Computer editing and generating of dynamic scenes of various targets and backgrounds have been actualized. At first, four elements composed the scenes are analyzed, i.e., target, background, moving pattern and special events. Then they are programmed into four modules to fulfil corresponding tasks. In the target and background modules, the images are processed and interest parameters are calculated. In the moving pattern module, the pattern is specified. In the events module, some typical events independent of target can be added. At last, using the synthesizing techniques, the required dynamic scenes are automatically generated by computer. The original target and background images can be easily got through the image DBMS.
