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 () comprising cyclically addressable light sources (S). The surface () is positioned behind a screen () comprising pixels (P) with a controllable light transmission or reflection. The light beams emitted from different light sources (S) illuminate the individual pixels (P) from different directions. According to the invention, the distance between the light sources (S) is larger than the distance between the pixels (P), and the light sources (S) are positioned so much away from the pixels so that the number of pixels (P) illuminated by one light source (S) is greater than the number of light sources illuminating one pixel (P).
