Abstract: A method and an apparatus for displaying 3D images are disclosed. 2D images are projected from multiple points to a surface with narrow diffusion characteristics, thus it is possible to get a 3D light field with arbitrary angular dependence. According to the invention, the projectors (10) do not target particular screen (12) points. The projectors (10) are directed to the screen (12) with no special positioning, however from the bunch of light beams present, pertaining to the large number of pixels in the projected images, it is possible to select and define a pixel-wise precise 3D light-field through a calibration process. A novel calibration method and device are also described for calibrating 3D display systems, the device being equipped with proper image sensor(s) and a control system.

Abstract: The invention is an image coding method for video compression, especially for efficient encoding and decoding of true 3D content, without extreme bandwidth requirements, being compatible with the current standards serving as an extension, providing a scalable format. The method comprises of the steps of obtaining geometry-related information about the 3D geometry of the 3D scene and generating a common relative motion vector set on the basis of the geometry-related information, the common relative motion vector set corresponding to the real 3D geometry. This motion vector generating step (37) replaces conventional motion estimation and motion vector calculation applied in the standard (MPEG4/H.264 AVC, MVC, etc.) procedures. Inter-frame coding is carried out by creating predictive frames, starting from an intra frame, being one of the 2D view images on the basis of the intra frame and the common relative motion vector set.

Abstract: An apparatus and an associated method for displaying 3D images includes a screen and a screen illuminating system. The screen has diffusion characteristics for direction selectively forwarding light. The screen illuminating system includes modules for generating light beams incident on points of the screen. The apparatus is configured to impart an exit divergence to the exiting light beams being transmitted through or reflected from the screen. Each module provides one beam in one direction with a convergent section. The beams are focused on the screen where the convergence (?c) of an incident light beam is not greater than the exit divergence (?x) of an exiting light beam.

Abstract: There is disclosed a method and apparatus for the presentation of three-dimensional images, where light beams with appropriate intensity and optionally with appropriate color are projected in different viewing directions and thereby creating a three-dimensional image. The light beams are created with a light emitting surface (10) comprising cyclically addressable light sources (S). The surface (10) is positioned behind a screen (20) comprising pixels (P) with a controllable light transmission or reflection.

These pixels (Cd) are pixels of a two-dimension display (50), and they are associated to different emitting directions (E) of the appropriate screen points (P).
