Abstract

The method and appliance for taking three-dimensional films involves taking a double picture simultaneously with only one cine camera in a first step with optical aids. In a second step with similar aids the double picture incorporates polarization filters or color filters. The two pictures are superimposed on the projection screen to produce a three-dimensional picture when viewed through special spectacles. Both lens mirrors are joined by a gear. The two deflector mirrors can be separately adjusted by means of a cog wheel mechanism.

Description

Die Erfindung betrifft ein Verfahren, das im ersten Schritt dreidimensionale Bilder auf einem Film aufnimmt, die im zweiten Schritt mit Hilfe eines Betrachtungsgerätes dreidimensional erscheinen. Dabei werden zwei unterschiedliche Verfahren angewendet. Von dem dreidimensionalen Vorgang wird simultan mit einer Kamera ein Doppelbild (2 Halbformatbilder) aufgenommen. Dieses Verfahren eignet sich besonders für hohe Bildfrequenzen und kürzeste Belichtungszeiten. Dazu wird ein spezieller optischer zweiäugiger Vorsatz verwendet der sich auf die Brennweite und den Objektabstand justieren läßt. Der so aufgenommene Film wird projiziert unter Verwendung eines ähnlich aufgebauten optischen Vorsatzes, der vor dem Projektionsobjektiv angeordnet ist. Dieser ist mit Polarisationsfiltern oder Farbfiltern z. B. rot-grün oder rot-blau ausgerüstet. Auf der Projektionsebene werden beide Bilder mit einer geringen Verschiebung überlagert, so daß beim Betrachten mit einer entsprechenden Polarisationsbrille oder einer Farbfilterbrille ein dreidimensionales Bild entsteht. Damit ist auch eine Beobachtung des aufgenommenen Vorgangs durch mehrere Personen gleichzeitig möglich.The invention relates to a method that in the first step three-dimensional images on a Recorded film in the second step with the help of a viewing device appear three-dimensional. Two different procedures are used. Of The three-dimensional process is simultaneously a double image with a camera (2nd Half-frame images). This method is particularly suitable for high Frame rates and shortest exposure times. For this, a special optical two-eye attachment used to adjust to the focal length and the object distance leaves. The film thus recorded is projected using a similar structure optical attachment, which is arranged in front of the projection lens. This is with Polarization filters or color filters e.g. B. equipped red-green or red-blue. On the Projection plane, both images are superimposed with a slight shift, so that when Consider using appropriate polarizing glasses or a color filter glasses three-dimensional image is created. This is also an observation of the recorded Operation possible by several people at the same time.

Die heute zum Einsatz kommenden 3-D-Systeme, die mit nur einer Aufnahmekamera arbeiten, verwenden das Filtersystem, das aber mit höheren Lichtverlusten verbunden ist. Dadurch ist der Einsatz auf niedrigere Bildfrequenzen beschränkt. Die üblichen Vorsätze für Doppelbild­ aufnahmen sind zwar für Einzelbilder z. B. Kleinbildaufnahmen gebräuchlich und geeignet, aber nicht für die Beobachtung von Lauffilmen. Das beschriebene Zweischrittverfahren umgeht diese Mängel indem es beide Verfahren mit Hilfe entsprechender optischer Vorsätze sowohl für die Aufnahme als auch für die Projektion miteinander verbindet. Es kann auch mit nur einem Vorsatz und geeigneten Adaptern gearbeitet werden.The 3-D systems used today, which work with only one camera, use the filter system, which is associated with higher light losses. This is use limited to lower frame rates. The usual double image resolutions recordings are for single images z. B. 35mm shots in use and suitable, but not for watching motion pictures. The described two-step process bypasses These shortcomings by eliminating both processes with the help of appropriate optical attachments connects the recording as well as for the projection. It can also be done with just one Intent and suitable adapters.

Anhand von Zeichnungen werden die optischen Vorsätze beispielsweise erläutert.The optical attachments are explained, for example, using drawings.

Fig. 1 zeigt einen zweiäugigen Vorsatz für die Aufnahme mit der Justiereinrichtung 1 zur Anpassung an die Brennweite des Aufnahmeobjektivs 2 und einer Einrichtung zur Einstellung auf das Objekt, was besonders bei Nahaufnahmen erforderlich ist. Die Spiegel 3 sind drehbar angeordnet. Vom Abstand der Austrittsöffnungen 4 ist die 3D- Wirkung abhängig. Fig. 1 shows a two-eyed attachment for the shot with the adjusting device 1 for adapting to the focal length of the taking lens 2 and a device for adjustment to the object, which is particularly necessary for close-ups. The mirrors 3 are rotatably arranged. The 3D effect is dependent on the distance between the outlet openings 4 .

Fig. 2 zeigt einen Vorsatz für die Projektion mit Filtern 5 vor den Austrittsöffnungen 4, der sonst ähnlich aufgebaut ist wie der Aufnahmevorsatz. Deshalb ist es möglich mit nur einem justierbaren Vorsatz sowohl für die Aufnahme als auch für die Projektion zu arbeiten. Fig. 2 shows an attachment for the projection with filters 5 in front of the outlet openings 4 , which is otherwise constructed similarly to the receiving attachment. It is therefore possible to work with just one adjustable attachment for both the recording and the projection.
