Abstract: A hologram generating apparatus is provided. The apparatus includes a hologram signal generating unit configured to, based on light projected on at least some points corresponding to an object, generate a hologram signal corresponding to the at least some points on at least one two-dimensional plane, a processor configured to calculate a sparsity corresponding to the two-dimensional plane based on the hologram signal, and to calculate a fringe pattern based on at least some of the hologram signal, and a pattern writing unit configured to record the fringe pattern on a computer-generated holography (CGH) plane, wherein the processor is further configured to repeatedly calculate a fringe pattern until a number of dominant signals of the calculated fringe pattern coincides with a predetermined threshold value determined based on the sparsity.

Abstract: A three-dimensional (3D) display apparatus is provided, including an image input device which receives an image and depth information, a multi-view image generator which generates a multi-view foreground image having depth information which is less than a preset depth value, and a multi-view rear ground image having depth information which is equal to or greater than the preset depth value, using the received image and depth information, a multi-view image renderer which performs rendering by arranging the multi-view foreground image according to a first arrangement pattern and the multi-view rear ground image according to a second arrangement pattern, and a display which outputs the rendered multi-view image.
