Abstract:
1. A method for generating video holograms for a holographic display device with at least one light modulator means, comprising: dividing a scene into object points; encoding the scene as an entire hologram onto said at least one modulator means; tracking a variable position of an observer eye, said position of said observer eye comprising a visibility region and the scene being viewable as a reconstruction from the visibility region, the visibility region lying within one periodicity interval of the reconstruction; encoding sub-holograms on the light modulator means, each of said sub-holograms being a subset of the entire hologram and comprising a size and a position depending on the position of the visibility region and a position of an object point of the scene to be reconstructed; and forming the entire hologram by superpositioning of said sub-holograms, where, in a sequence of image contents for each image:
