in der Wagerechten verschiebbar sind. Bei der Exposition läuft das Filmband an einer Fensteröffnung vorbei, die so klein ist, dass nur ein Drittel des Bandes exponiert wird. Die Kamera ist so eingerichtet, dass sie das Farbenbild auf die übliche Grösse verkleinert. Es wird nun durch den ersten Farbenfilter zunächst das linke Drittel des Filmbandes exponiert, während die beiden anderen Drittel lichtdicht abgeschlossen bleiben.
Sodann wird das Filmband zurückgerollt und es werden die Spulen so verschoben, dass das mittlere Drittel vor die Fensteröffnung gelangt und es wird alsdann dieses durch den zweiten Farbenfilter exponiert, während die beiden äusseren Drittel bedeckt bleiben. Schliesslich wird unter Verwendung des dritten Farbenfilters in gleicher Weise nach abermaligem Zurückrollen mit dem letzten Drittel verfahren.
Auf diese Weise erhält man unter Abstufung der Expositionszeiten je nach Lichtdurchlässigkeit der Farbenfilter drei vollkommen gleich lichtstarke Teilnegative auf einem Filmbande unverrückbar in genau gleichen Abständen nebeneinander.
Von diesem Negativband wird dann das zur Projektion dienende Positivband in beliebiger Anzahl hergestellt.
Dieses Verfahren hat den Vorteil, dass bei der Projektion der Raster sich nicht bemerkbar machen kann und die Teilbilder nach einmaliger Einstellung genau übereinander liegen.
PATENT-ANSPRÜCHE :
1. Verfahren zur Aufnahme und Wiedergabe bewegter Bilder in den Naturfarben, dadurch gekennzeichnet, dass zunächst eine farbenphotographische Aufnahme auf einer mit Farbenraster versehenen lichtempfindlichen Schicht gemacht wird, worauf von den erhaltenen Farbenbildern die vorzuführenden Bilder nach dem Verfahren der Dreifarbenphotographie als Monochrome hergestellt werden.

can be moved in the horizontal plane. During exposure, the film tape runs past a window opening that is so small that only one third of the tape is exposed. The camera is set up in such a way that it reduces the color image to the usual size. The left third of the film strip is now exposed through the first color filter, while the other two thirds remain light-tight.
The film tape is then rolled back and the coils are shifted in such a way that the middle third reaches the window opening and this is then exposed through the second color filter, while the two outer thirds remain covered. Finally, using the third color filter, proceed in the same way after rolling back again with the last third.
In this way, with gradation of the exposure times depending on the light transmission of the color filters, three completely equally bright partial negatives are obtained on a film strip immovably next to one another at exactly the same intervals.
Any number of the positive tape used for projection is then produced from this negative tape.
This method has the advantage that the grid cannot be noticeable during the projection and the partial images lie exactly on top of one another after a one-off setting.
PATENT CLAIMS:
1. A method for recording and reproducing moving pictures in natural colors, characterized in that a color photographic recording is first made on a light-sensitive layer provided with a color raster, whereupon the images to be presented are produced as monochrome from the color images obtained using the three-color photography method.
