Abstract
A method and apparatus for generating/converting a digital hologram is provided. The method for generating the digital hologram includes: clustering points of a 3D object to a plurality of clusters according to a distance to a screen; generating diffraction patterns in a unit of a cluster; and generating a fringe pattern by overlapping the diffraction patterns with one another. Accordingly, calculation complexity can be reduced and thus it is possible to generate a digital hologram at high speed. Since a range/size of a cluster which has a trade-off relationship with an image quality of a digital hologram is adjustable, it is possible to generate a customized flexible digital hologram.
