Abstract
Simultaneously and automatically with creating a CG image by computer graphics, (1) the image is segmented to create a mask image, (2) a mask attribute table is created by data transformation, (3) an intrinsic image (object color component, light source color component, ambient color component) is created by data transformation, and the results are saved. The mask image is used to cut a portion from the computer graphics image and the cut portion is combined with a different image, which may be a natural image for example, to obtain a composite image, and at the same time, transparency processing or other such image processing is conducted on the basis of the attribute data. In addition, the color etc. of the object are modified by changing the object color vector or the like.
