摘要
The invention relates to an apparatus for projecting a moving or still stereo or multichannel image (IM), said apparatus comprising at least a first (R) and at least a second (L) video projector, or the like, for projecting images intended for the left and the right eye of a viewer (H) alternately in time and in synchronization with the function of shutter glasses (G) or the like worn by the viewer. According to the invention, said video projectors are liquid crystal video projectors (PI) in which liquid crystal video projectors (PI) the illuminating, and thereby image-projecting light source (FP) of the liquid crystal matrix (LC) is a light source (FP) that produces light in a pulsed manner, the pulsing of said light source (FP) being arranged to occur in synchronization with the presentation of images. The pulsing of light sources according to the invention enables the projection of high-quality stereo image by means of affordable liquid crys-tal video projectors functioning at the normal image frequency.
