Imaging processing method for mapping video source information onto a displayed object
First Claim
1. A video processing apparatus, comprising:
- first video processing means for performing a spatial transformation on a first source video by reading said first source video from a first memory in accordance with a first read address data in order to generate a first two-dimensional transform video;
second video processing means for performing a spatial transformation on a second source video by reading said second source video from a second memory in accordance with a second read address data in order to generate a second two-dimensional transform video;
third video processing means for performing a spatial transformation on a third source video by reading said third source video from a third memory in accordance with a third read address data in order to generate a third two-dimensional transform video;
composite means for combining said first, second and third two-dimensional transform video to generate a two-dimensional composite video; and
control means for generating said first read address data, said second read address data and said third read address data, and for modifying said second read address data and said third read address data in accordance with said spatial transformation to be performed on said first source video so that said two-dimensional composite video image appears as a desired three-dimensional object.

Abstract
An image processing apparatus and the method for mapping a plurality of images which are on the two-dimensional plane on the corresponding faces of a solid in the three-dimensional virtual space. The mapping image on the side face being close to the object image displaying face is formed in accordance with the shape of object image displaying face of the solid on which the object image is mapped, and the image mapped on each face is displaced in accordance with the movement of the solid in the three-dimensional space. Therefore, the image that as if a desired image is stuck to the faces of the solid moving in a virtual space can be displayed on a screen surface by easily operating by an operator.
