Patent ID: 8437056

Claim:
A method for computing a video hologram of a scene to be reconstructed, which scene to be reconstructed comprises a multitude of object points for use in a holographic display device with at least one light modulator means, comprising: defining a visibility region within a periodicity interval of the video hologram of the scene to be reconstructed; for each object point, defining a modulator region by the defined visibility region together with each object point of the scene to be reconstructed, where a sub-hologram of an object point of the scene to be reconstructed is computed in each modulator region, and where the video hologram is created by superposition of said sub-holograms; determining complex hologram values of a sub-hologram in a modulator region from a wave front of an object point to be reconstructed; and computing and analyzing transmittance functions or modulation functions of an imaging element of said holographic display device, which is modelled in the modulator region, and which comprises at least one modelled prism, and in whose focal point the object points to be reconstructed lie, where the sub-hologram of said object points are computed using the transmittance or modulation functions.
