Patent ID: 7084841

Claim:
Method for the presentation of three-dimensional images, where light beams with appropriate intensity and optionally with appropriate colour are projected in different viewing directions, thereby creating a three-dimensional image, wherein: a, a light emitting surface comprising light sources controllable in control cycles with angle independent or time-constant angle dependent radiation characteristics is positioned behind a screen, the screen comprising image pixels with a controllable light transmission or reflection, where b, the light beams emitted from a predetermined number of different light sources illuminate the individual image pixels from different directions, one image pixel being illuminated in each control cycle at least one by each of the predetermined number of light sources, c, the direction of the light beams emitted from the individual image pixels are determined by the direction of the light beams that are emitted by the light sources and propagating between the light sources and the image pixels substantially without changing direction, and further d, the distance between the centres of neighboring light sources is selected to be larger than the distance between the centres of neighboring image pixels, wherein e, the distance between the centres of neighboring light sources and the distance between the light emitting surface and the screen are selected so that the number of image pixels illuminated by one light source is greater than the predetermined number of light sources illuminating one image pixel.
