  • Method and apparatus for generating elemental image in integral imaging
    Patent number: 8643645
    Abstract: A method and apparatus for generating an elemental image by an integral image technique are provided. The method includes normalizing coordinates of dots in a frustum formed in perspective projection by mapping the dots in the frustum into a cube; reversing a grade of depth of the cube viewed from a particular viewpoint; and generating a two-dimensional (2D) elemental image necessary for three-dimensional (3D) display from dots in the cube whose grade of depth is reversed.
