Реферат: 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 (L, R) are provided with a shutter means / several shut-ter means (DS, LCS) to prevent the projection of an image, if necessary, the control of said shutter means being arranged in synchronization with the showing of the images in the following manner. When the right-eye shutter (R') of the shutter glasses (G) or the like worn by the viewer (H) is open, the shutter means (LS;LCS) in connection with at least the second projector (L) pro-jecting the image intended for the left eye is/are con-trolled to be shut, and correspondingly, when the left-eye shutter (L') of the shutter glasses (G) or the like worn by the viewer (H) is open, the shutter means (LS;LCS) in connection with at least the first projector (R) projecting the image intended for the right eye is/are controlled to be shut. The invention enables the projec-tion of a high-quality stereo image by means of afford-able video projectors, for example liquid crystal video projectors functioning at the normal image frequency.
