Patent ID: 8368743

Claim:
An interface with at least one encoding unit, where the interface transmits digital image data with depth information to a holographic encoding unit, where the holographic encoding unit generates from the digital image data with depth information complex hologram values and/or pixel values for controlling at least one light modulator means of a holographic display device, where the at least one light modulator means of the holographic display device controlled by the complex hologram values and/or pixel values controls the amplitude and/or phase values of a light wave front, where the interface transmits using a transmission means and a communication protocol to the holographic encoding unit a depth map and, separately, a colour map of the image data, where the depth map comprises the depth information and where the colour map comprises the colour information of pixelated images of an image sequence, and where the interface is further configured such that the depth map is read from a Z buffer and the colour map is read from a frame buffer of a graphics card or from other dedicated memory areas of a graphics system, where the holographic encoding unit generates based on the depth map and the colour map complex hologram values, which are used to control the holographic display device in order to reconstruct an entire video hologram which represents a scene which is divided into object points, the entire video hologram can be seen from a visibility region, said visibility region lying within one periodicity interval of the reconstruction of the entire video hologram, and where the visibility region defines a sub-hologram together with each object point to be reconstructed of the scene which is represented by the depth map, and where the entire video hologram is formed by superimposition of sub-holograms.
