PROBLEM TO BE SOLVED: To suppress unnaturalness of a composited image when a real picture (a moving picture) is composited into a computer graphics(CG). SOLUTION: An image pickup part 2 picks up an image of a plate 1 while moving. When a ball created in a computer graphics CG is composited into continuous pictures picked up by the image pickup part 2, how twelve patterns (surrounded by a frame 21) near the ball 5 Aj (j indicates 1 to 12) are converted into the continuous pictures picked up by the image pickup part 2 is indicated by a rotational conversion function and a rectilinear transduction function and, with these rotational conversion function and rectilinear transduction function, a composited position of an projected image of the ball 5 is obtained for each picture. |
