Abstract.  Coarse integral volumetric imaging (CIVI) combines multiview and volumetric display solutions and presents undistorted floating 3D images by correcting distortion of volumetric image for each view. In the conventional CIVI with limited viewing angle, distortions of image planes can be approximated to be parabolic in the direction of depth, while those in horizontal and vertical directions can be ignored. When the viewing angle becomes wider, however, this approximation cannot realize presentation of the undistorted image. To cope with the strong distortions, the method that the authors propose calculates the z-coordinate of the generated real image in detail and depicts each pixel on the display panel of the corresponding depth. Also distortions in horizontal and vertical directions are corrected by using texture mapping. To attain precise correction in vertical, horizontal and depth directions, optical paths of light rays between the display panel and each viewpoint are calculated with an optical simulator. Color aberration can also be corrected by mapping red, green and blue textures separately based on the result of the optical simulation.
