PURPOSE:To allow the exact adjustment of the size of a superposing image by previously setting three-dimensional position information on the object appearing in a background image and automatically calculating the magnification ratio and reduction ratio of the superposing image from the two-dimensional position in the background image. CONSTITUTION:The superposing image is automatically magnified or reduced to the size suitable for the superposing position thereof and is synthesized by superposition when the superposition place (superposing position) is assigned by using the three-dimensional information applied in the background image. The synthesized images superposed with the superposing image in the state of having a natural perspective feel on the background image is automatically obtd. in this way without making laborious operation. The labor for assigning the magnification ratio and reduction ratio at every time of changing the position of the superposed image, changing its layout, etc., is eliminated. |
