"Method and device for forming a combination of a real object with a background and an image recording of this combination ¹ '

The invention relates to a method and a device for forming a combination of a real object or a person with the background and an image recording of this combination, in which the formation of the background by electronic means, the dynamic reshaping of the background depending on the action of the real one Object or person on the scene of the projection is released onto the moving screen o

Jüs is familiar with the methods and devices for forming, for example, a combination of the actor on the stage and his image with the background, which is projected onto the screen on the stage by a projection apparatus. In front projection, it is bothersome that the image of the background is also projected onto the object or person on the scene, or that the object or person on the scene has to be outside the projected background. There is usually not enough space behind the scene for the background projection "in addition, the background when projecting shape, color can u _or the like" are affected depending on the action of the real object or person on the scene in any way. If z. B ₀ a slide or a film is projected onto the moving screen, this wall must follow the movement of the projected image and not the other way around to combine the person with the background and the process for forming the moving mask is known from film technology. In all of these cases it is
