In order to sustain illumination of a screen between images of views projected in succession onto it, a flat reflector (1 or 77), mobile in its own plane by rotation or translation respectively, is placed between the lens of said view projector and the location of the illumination during a change in view, thus blocking the light for projecting the views, which comes from the direction (A) and goes in the direction (C), and therefore reflecting, in the direction (C), an auxiliary light coming from the direction (B). Said flat reflector is withdrawn while the views are being projected. Two reflectors, mobile by translation, may also be moved symmetrically. |
