Description

Verfahren zum Erzeugen stereoskopischer Wirkung bei Kinobildern. Gegenstand der Erfindung ist ein Verfahren, um stereoskopische Wirkungen bei kinematographischen Projektionsbildern zu erhalten. Es ist bereits vorgeschlagen worden, ein rechtes Bild Ar zu projizieren, dem ein linkes Bild AL folgt, und dann ein rechtes Bild Br zu projizieren, auf das ein linkes Bild BI folgt usw.; aber infolge der Geschwindigkeit, mit welcher der Film bewegt wird (gewöhnlich 16 Bilder je Sekunde), bewirkt (las abwechselnde Abdecken des rechten und linken Auges ein solches Flimmern, daß das Verfahren praktisch nicht verwendbar ist. Um das Flimmern zu beseitigen, werden nach der Erfindung die rechten und linken Aufnahmen desselben Bildes mehrere Male in Abwechslung auf den Schirm geworfen.Method for generating stereoscopic effects in cinema images. The invention relates to a method for obtaining stereoscopic effects in cinematographic projection images. It has already been proposed to project a right image Ar followed by a left image AL and then project a right image Br followed by a left image BI, etc .; but due to the speed at which the film is moved (usually 16 frames per second), alternating covering of the right and left eyes causes such flicker that the method is practically unusable. To eliminate the flicker, after the Invention, the right and left images of the same image are thrown alternately on the screen several times.

Das Verfahren besteht also im Projizieren von rechten und linken Bildern in schneller Aufeinanderfolge und mehrere Male hintereinander. Wenn z. B. gewünscht wird, jedes Bild dreimal zu projizieren, so wird die rechte AufriahmeAr projiziert und mit dem rechten Auge gesehen, dann wird die linke Aufnahme AL projiziert und mit dem linken Auge gesehen, darauf wird wiederum dieselbe rechte Aufnahme Ar projiziert und ein zweites Mal mit dem rechten Auge gesehen, worauf dieselbe linke Aufnahme Al ein zweites Mal mit dem linken Auge gesehen wird, und schließlich wird die rechte Aufnahme Ar noch einmal projiziert und ein drittes Mal mit dem rechten Auge gesehen, und ebenso wird die linke Aufnahme Al noch einmal projiziert und ein drittes Mal mit dem linken Auge gesehen. Dann erst wird der Film weitergeschaltet, um die Aufnahmen Bi- und BI in <ilinlicher Weise auf den Schirm zu werfen.The method consists in projecting right and left images in quick succession and several times in a row. If z. For example, it is desired to project each image three times, then the right image Ar is projected and seen with the right eye, then the left image AL is projected and viewed with the left eye, and the same right image Ar is projected thereon again and a second time seen with the right eye, whereupon the same left picture Al is seen a second time with the left eye, and finally the right picture Ar is projected again and seen a third time with the right eye, and likewise the left picture becomes Al again projected and seen a third time with the left eye. Only then is the film switched on in order to throw the recordings BI and BI onto the screen in a similar manner.
