ABSTRACT:
In an apparatus for projecting a picture on a projection screen, having a light source (1) emitting light, whereby a luminous area (3) can be generated with said light, having a reflective light modulator (12, 13, 14) that can receive the light emitted from the luminous area (3) and modulates it for the purpose of generating a picture, and further having a projection optics (16) arranged following the light modulator (12, 13, 14) in order to project the picture on the projection screen (17), wherein an optics system (7, 23, 31, 33, 34) is arranged in front of the light modulator (12, 13, 14), wherein the optics system images the light received from the luminous area (3) on the light modulator (12, 13, 14) on the one hand, and on the other hand images the light modulated by means of the light modulator (12, 13, 14) in order to generate a picture in the intermediate image level (ZE) that can be projected on the projection screen by the projection optics.
