<P>PROBLEM TO BE SOLVED: To form a plane image for IP from which a three-dimensional (3D) image having a large degree of freedom can be reproduced by introducing general computer graphics (CG). <P>SOLUTION: A 3D image preparation method is used in a 3D display apparatus which displays a plane image 2 of a background through a two-dimensional (2D) lens array 1 constituted of M×N micro convex lenses, and the method comprises the steps of: setting a reference visual distance between the plane image 2 and a position for observing a 3D image, a visual area V and i×j visual points in the visual area V; generating a virtual object by general CG on the basis of the set contents; selecting one visual point and one convex lens; calculating an intersection of the extension of a line connecting the visual point to the center of the convex lens and the surface of the plane image 2; recording image data along a line connecting the visual point and the convex lens on a calculation point as a pixel; recording pixels concerned with all the visual points about the convex lenses on the plane image 2 by repeating similar operation to complete a unit plane image; and selecting another convex lens and repeating similar operation to complete unit plane images 2 for all the convex lenses. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
