Dynamic image composition apparatus and method

Abstract

The movement of an image component is determined using the plot information, such as the position, size of the image component, etc., at each time. The complex movement of each image component can be easily generated by providing a plurality of plot information generating units for each image component and combining a plurality of pieces of plot information generated by the plot information generating units when an image is reproduced.

1 . A dynamic image composition apparatus for combining and plotting one or more images, comprising: 
 an image management device provided for each image, for including a plurality of sequentially ordered plot information generating devices for generating plot information used to plot a dynamic image, a first plot information generating device updating plot information at a previous time and passing the plot information to a subsequent plot information generating device, an intermediate plot information generating device updating plot information provided by a preceding plot information generating device and passing the plot information to a subsequent plot information generating device, and a last plot information generating device updating plot information provided by a preceding plot information generating device and generating plot information at a present time; and    a plotting device for receiving the plot information at the present time from the image management device and plotting a corresponding image based on the plot information at the present time.    
   
   
       2 . The dynamic image composition apparatus according to  claim 1 , wherein 
 each plot information generating device generates a difference of plot information between the previous time and the present time, adds the difference to inputted plot information and updates the inputted plot information.    
   
   
       3 . (canceled)  
   
   
       4 . A computer-readable storage medium on which is recorded a program for enabling a computer to execute a process, the process comprising: 
 generating plot information at a present time by updating plot information used to plot an image at a previous time for each image by a plurality of sequentially ordered plot information generating processes; and    plotting each image based on the plot information at the present time.
