Description

Vorrichtung zum Herstellen und Wiedergeben von Kinobildern in natürlichen Farben. Für diese Anmeldung ist gemäß dem Unionsvertrage vom z. Juni igi i die Priorität auf Grund der Anmeldung in der Schweiz vom 2. September 1921 beansprucht. Die Erfindung bezieht sich auf eine Vorrichtung zur Herstellung und Wiedergabe von kinematographischen Bildern in natürlichen Farben. Es sind bereits Vorrichtungen dieser Art bekannt geworden, bei denen durch möglichst nahe beieinanderliegende Linsen die zur Farbenkinematographie notwendigen Teilbilder gewonnen werden; es ist z. B. vorgeschlagen worden, das durch ein Objektiv gewonnene Bild durch ein aus verschiedenen Teilen lose zusammengefügtes Objektiv in mehrere Teilbilder zu zerlegen.Device for producing and reproducing natural cinema images Colours. According to the Union Treaty of z. June igi i the priority claimed on the basis of the registration in Switzerland on September 2, 1921. The invention refers to an apparatus for making and playing cinematographic Images in natural colors. Devices of this type are already known where the lenses for color kinematography are as close as possible to one another necessary partial images are obtained; it is Z. B. has been proposed by an image obtained from an objective lens through an image loosely assembled from different parts Objective to be broken down into several partial images.

Das Neue besteht nun darin, daBbeider Einrichtung alle Linsenteile mit ihrer einen, im zusammengesetzten Zustand. - auf einer Kugel liegenden Fläche in einer gemeinsamen konkaven Kugelfläche einer Linse fest aufliegen. Dadurch wird nicht nur ein weitaus einfacherer Zusammenbau nies Objektives erreicht, sondern es bleibt auch die Lage der Einzellinsen in bezug aufeinander :und damit die optischen Verhältnisse unveränderlich.The new thing now is that when setting up all lens parts with one of them, in the assembled state. - surface lying on a sphere rest firmly in a common concave spherical surface of a lens. This will not only achieved a much easier assembly, but never objective the position of the individual lenses in relation to one another also remains: and thus the optical ones Relationships immutable.

In der Zeichnung ist schematisch ein Ausführungsbeispiel im Schnitt dargestellt unter Andeutung des Strahlenganges.In the drawing, an exemplary embodiment is schematically shown in section shown with indication of the beam path.

Die Linse i weist zwei Teile oder Hälften auf, die mit konvexen Flächen 2, 3 versehen sind. Die Flächen 2, 3 stoßen aneinander, .und deren optische Mittelpunkte haben an der Linse einen Abstand d voneinander. Die Flächen 2, 3 sind ,einander vollkommen gleich, i sie sind schräg zueinander gestellt und zur wagerechten Mittelebene symmetrisch. Die j Rückseite 4 der Linse i bildet einen Teil einer Kugelfläche, und mit dieser Kugelfläche ruht die Linse r in einer genau entsprechenden konkaven Fläche einer Linse 5.The lens i has two parts or halves, those with convex surfaces 2, 3 are provided. The surfaces 2, 3 abut one another, and their optical centers are at a distance d from one another at the lens. The faces 2, 3 are, one another completely the same, i they are placed at an angle to each other and to the horizontal central plane symmetrical. The j back 4 of the lens i forms part of a spherical surface, and with this spherical surface the lens r rests in an exactly corresponding concave Surface of a lens 5.

Ein von einem Objektiv erzeugtes Bild G wird durch die Linsen i, 5 in zwei Teilbilder B, B, die unmittelbar übereinanderliegen und einander vollkommen gleich sind, zerlegt. Diese Teilbilder werden in bekannter Weise auf einen Film :geworfen, wobei zwischen Linse i und Film Farbfilter eingeschaltet sind.An image G generated by an objective is broken down by the lenses i, 5 into two partial images B, B, which are directly above one another and are completely identical to one another. These partial images are projected onto a film in a known manner, with color filters being inserted between lens i and film.

Zur Wiedergabe der Teilbilder B, B vorn Film kommt dieselbe Linse i, 5 zur Verwendung. Diese erzeugt wieder ein reelles, buntes Bild, das mittels einer Projektionsvorrichtung auf den Lichtschirm geworfen wird.The same lens i, 5 is used to reproduce the partial images B, B from the film. This again creates a real, colorful image that is projected onto the light screen by means of a projection device.

PATENT-ANSPRUcH: Vorrichtung zum Aufnehmen und Wiedergeben von kinematographischen Bildern in natürlichen Farben mittels nebeneinanderliegenden Linsen, welche ein von einem Objektiv erzeugtes Bild in genau gleiche Teile zerlegen oder letztere wieder zu einem Bild vereinigen, dadurch gekennzeichnet, daß eine aus zwei genau gleichen, schräg zueinander gestellten und mit konvexen Flächen (2, 3) versehenen Hälften bestehende Linse (i) eine als ugelteilfiäche ausgebildete Rückseite (q.) besitzt und mit dieser an einer der Rückseite (q.) genau entsprechenden konkaven Seite einer Linse (5) fest anliegt. PATENT CLAIM: Device for recording and reproducing cinematographic images in natural colors by means of lenses lying next to one another, which split an image generated by an objective into exactly the same parts or combine the latter again into one image, characterized in that one of two exactly the same, oblique Lens (i), which are positioned relative to one another and have halves (2, 3) provided with convex surfaces, has a rear side (q.) designed as a partial surface and with this rests firmly against a concave side of a lens (5) which exactly corresponds to the rear side (q.) .
