    Vorrichtung zur Erzeugung farbiger J :inematographischer Bilder.   



   Den Gegenstand der Erfindung bildet eine Vorrichtung zur Herstellung von Photographien in natürlichen Farben, insbesondere für kinematographische Zwecke. Das Wesen der Erfindung besteht darin, dass durch einen verhältnismässig grossen beweglichen Reflexspiegel die Lichtstrahlen den drei hintereinanderliegenden stufenweise kleiner werdenden beweglichen Objektivspiegel zugeleitet werden. 



  Wegen der kleinen Kinobilder sind die Brennweiten kurz. Diese kurzen Brennweiten haben den Nachteil, dass die Spiegelfassungen bzw. die Streifenversilberung mitphotographiert werden. Es ist notwendig, die nach allen Seiten beweglichen Spiegel direkt vor die Objektivlinse zu bringen. Um einen grossen Bildwinkel zu erzielen, ist es nötig, einen sehr grossen Reflexspiegel anzubringen. Die Objektivspiegel sind in ihrer Grösse abgestuft, u. zw. so, dass der oberste Spiegel grösser als der mittlere und dieser grösser als der hintere Spiegel ist. Durch diese Abstufung in Verbindung mit dem grossen Reflexspiegel ist ein Mitphotographieren der Spiegelfassung ausgeschlossen, bei gleichzeitiger Vergrösserung des Bildfeldes.

   Wäre z.   B-   der vom nahe dem ersten Objektiv liegende Spiegel gerade so gross, wie der Reflexspiegel, so würde die Rückseite der Fassung des Reflexspiegels durch das erste Objektiv abgebildet. Entsprechendes gilt für die anderen Objektive und Spiegel. 



   Um das Entstehen von Doppelbildern zu verhindern, werden für das obere und mittlere Objektiv keilartige Prismen vorgesehen. 



   Eine Lichtverteilung ohne Objektivblende kann dadurch erfolgen, dass der untere Prismenwinkel im Mittelspiegel durchsichtig versilbert wird. 



   Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung zur Darstellung gebracht, u. zw. bezeichnet : 1 den Reflexspiegel, 2, 3, 4 die Objektivspiegel und 5 die Objektive. Der Reflexspiegel sowie die Objektivspiegel sind beweglich angeordnet, u. zw. sitzt beispielsweise jeder Spiegel vermittels. Drehzapfen 7 in einem Rahmen, der um nen Zapfen 6 drehbar ist (Fig. 3). Die Objektivspiegel sind unmittelbar vor den Objektiven angeordnet, um in Verbindung mit dem grossen Reflexspiegel das denkbar grösste Bildfeld auch für das, unterste Objektiv zu erreichen.

    Apparatus for producing colored J: inematographic images.



   The subject of the invention is a device for the production of photographs in natural colors, in particular for cinematographic purposes. The essence of the invention consists in the fact that the light beams are fed to the three successive movable objective mirrors, which are gradually becoming smaller, through a relatively large movable reflective mirror.



  Because of the small cinema images, the focal lengths are short. These short focal lengths have the disadvantage that the mirror mounts or the strip silver plating are also photographed. It is necessary to bring the mirrors, which can be moved in all directions, directly in front of the objective lens. In order to achieve a large angle of view, it is necessary to attach a very large reflective mirror. The lens mirrors are graded in size, u. so that the top mirror is larger than the middle one and this one is larger than the rear mirror. This gradation in conjunction with the large reflective mirror prevents the mirror mount from being photographed while at the same time enlarging the image field.

   Z. If the mirror lying close to the first objective is just as large as the reflex mirror, the rear side of the mount of the reflex mirror would be imaged by the first objective. The same applies to the other lenses and mirrors.



   In order to prevent double images from occurring, wedge-like prisms are provided for the upper and middle lenses.



   A light distribution without an objective diaphragm can be achieved by silver-plating the lower prism angle in the center mirror.



   In the drawing, an embodiment of the invention is shown, u. Zw. denotes: 1 the reflex mirror, 2, 3, 4 the objective mirror and 5 the objective. The reflex mirror and the lens mirror are movably arranged, u. between, for example, each mirror sits mediating. Trunnion 7 in a frame which is rotatable about NEN pin 6 (Fig. 3). The lens mirrors are arranged directly in front of the lenses in order to achieve the largest imaginable field of view for the lowest lens in conjunction with the large reflective mirror.
