Title: Device for the production of an image on a screen by illuminating picture elements in a plurality of partial images

Abstract: In an apparatus for generating an image on a screen by illuminating image points in a plurality of partial images by light bundles, wherein the apparatus has at least one deflection device for deflecting a plurality of light bundles in respectively associated image points of the individual partial images, and a control device for controlling the intensity of the light bundles depending on the brightness of the respective image point to be illuminated, and optics between the screen and deflection device for deflecting the light bundles in a partial image associated with the respective light bundle, it is provided that the optics include an entrance pupil which is spread out over an extended area and an exit pupil which is much smaller in comparison to the entrance pupil, and in that a plurality of deflection devices for deflecting a light bundle associated with a partial image are provided in or near the entrance pupil which is spread out over an extended area.
