Description
Gemäß dem den Gegenstand' der- Erfindung bildendem Verfahren zur Vorführung kinematographischer Darstellungen erfolgt die Bildprojektion mittels eines einzigen Kinematographerj auf einen undurchsichtigen: und gleichzeitig auf einen- durchsichtigien Teil der Pro j ektionsfläche derart, daß beide Projektionen seitenrichtig Beschauern! der vorderen und rückwärtigen Seite der ProjektionswandAccording to the subject of the invention educational method for the presentation of cinematographic representations takes place Image projection using a single cinematographerj on an opaque: and at the same time on a transparent part of the Pro j ektionsfläche such that both projections the wrong way around! the front and back of the screen
ίο vorgeführt werden können·. Dies wird durch eine besondere Anordnung von Spiegeln mit Bezug auf den z. B. seitlich des Zuschauerraumes aufzustellenden Vorfühirungsapparat erreicht. Die Zeichnung veranschaulicht ein.ίο can be demonstrated ·. This is going through a special arrangement of mirrors with reference to the z. B. side of the auditorium to be set up demonstration apparatus achieved. The drawing illustrates a.
Ausführungsbeispiel.Embodiment.
A bezeichnet den seitlich vom Zuschauerraum aufgestellten Kinematographien und a, b zwei Spiegel, die gegenseitig und mit Bezug auf die optische Achsie des Kinematographen>objektivs geneigt angeordnet sind. Zwischen diesen beiden Spiegeln a, b ist eine durchsichtige Spiegelscheibe c angeordnet, so daß zwei Projektionen erfolgen: ein.mal wird daisi Bild mittels der durchsichtigen Glasscheibe ο auf den Spiegel α und das andere Mal durch die Glasschieibe c hindurch auf den Spiegel b reflektiert. Die Projektion des Bildes von a wird auf die untere, undurchsichtige Hälfte d der Projektionsfläche, das Bild von b auf die obere, durchsichtige Hälfte d' 'derselben, Projektionsfiäche projiziert, und zwar in beiden Fällen seitenrichtig, derart, daß das eine Bild von Beschauern der vorderen! und das andere von solchen der rückwärtigen Seite der Projektionsfläche seitenrichtig beobachtet werdfeni kann. A denotes the cinematography set up to the side of the auditorium and a, b two mirrors, which are arranged so as to be inclined to one another and with respect to the optical axis of the cinematograph> objectively. A transparent mirror plate c is arranged between these two mirrors a, b , so that two projections take place: once the image is reflected by means of the transparent glass plate o onto the mirror α and the other time through the glass plate c onto the mirror b . The projection of the image of a is projected onto the lower, opaque half d of the projection surface, the image of b onto the upper, transparent half d ' ' of the same, projection surface, and in both cases correctly laterally, in such a way that one image of the onlookers the front one! and the other side can be observed correctly from those on the rear side of the projection surface.
Dieses Verfahren ist für alle Arten von kinematographischen Darstellungen, insbesondere auch für das in der Patentschrift 293573 beschriebenie Verfahren zum Dirigieren einer Musikkapelle unter Benutzung eines die Person des Dirigenten vorführenden Kinematographen vorteilhaft anwendbar.This method is particularly useful for all types of cinematographic presentations also for the method of conducting described in patent 293573 a band using a cinematograph showing the person of the conductor advantageously applicable.
Statt einer einzigen Projektionsfläche kann· man auch zwei getrennte verwenden. 'Instead of a single projection surface, it is also possible to use two separate ones. '
