Abstract

The method involves recording periodically a scene or object using different angles. The different angles of a camera are guaranteed by alternating switching of a shutter. The shutter is synchronised with the video signal. Preferably, the method for viewing the three-dimensional picture of the video reproduction involves using shutter spectacles. The shutter spectacles guarantee that the user sees only appropriate pictures. The shutter spectacles are synchronised with the video signal so that only the periodical correct assigned pictures are presented to the appropriate eye.

Beschreibungdescription

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen 3D-Videofilm oder 3D-Videoaufnahmen erstellen zu können und unter Verwendung einer Shutterbrille und eines standardisierten Fernsehapparates, mit einem dreidimensionalen Seheindruck betrachten zu können.The present invention has for its object a 3D video film or 3D video recordings and using one Shutter glasses and a standardized TV set, with one to be able to view three-dimensional visual impression.

Dazu wird auf einer standardisierten Videokamera der 3D-Vorsatz am Kameraobjektiv befestigt und mit der Steuereinheit verbunden. Der 3D-Vorsatz bewirkt, daß das betrachtete Objekt periodisch durch zwei Sehkanäle aufgenommen wird. Die Sehkanäle befinden sich in einem Abstand, der dem durchschnittlichen Augenabstand eines erwachsenen Menschen entspricht. Die periodische Aufnahme des Objektes wird durch eine optische Filteranordnung (Shutter) erreicht. Die Sperr- und Durchlaßfrequenz der Shutter entspricht der Bildwiederholfrequenz. Dabei werden die Shutter durch die Steuereinheit so angesteuert, daß während des Sperrzustandes des einen Shutters der zweite Shutter sich im Durchlaßzustand befindet und umgekehrt, so daß Aufnahmen mit unterschiedlichem Blickwinkel entstehen.For this purpose, the 3D attachment is on a standardized video camera Camera lens attached and connected to the control unit. The 3D header causes the viewed object periodically through two visual channels is recorded. The visual channels are at a distance that the corresponds to the average eye relief of an adult. The periodic recording of the object is through an optical filter arrangement (Shutter) reached. The blocking and pass frequency of the shutter corresponds to Refresh rate. The shutter is controlled by the control unit controlled that during the blocking state of one shutter the second Shutter is in the open state and vice versa, so that shots arise with different perspectives.

Um bei der Wiedergabe des Filmmaterials einen dreidimensionalen Seheindruck zu erhalten muß eine Shutterbrille vom Bediener getragen werden. Diese Shutterbrille ist mit der Steuereinheit verbunden. Die Steuersignale der Steuereinheit gewährleisten die Zuordnung zwischen den Aufnahmesignalen und den Wiedergabesignalen.To give a three-dimensional visual impression when the footage is reproduced To get a pair of shutter glasses must be worn by the operator. This Shutter glasses are connected to the control unit. The control signals of the Control unit ensure the assignment between the recording signals and the playback signals.

Unter Verwendung eines Adapterstückes kann diese Vorrichtung an optischen Geräten bspw. Mikroskopen, Spaltlampen angeflanscht werden, womit dreidimensionale Aufnahmen vom Mikroskoproben bzw. von Augen erzielt werden können. Weiterhin ist es zum Beispiel möglich unter Verwendung einer sich drehbaren Spiegelanordnung eine Anpassung für Nah- bzw. Makroaufnahmen zu erzielen.Using an adapter piece, this device can be used on optical Devices such as microscopes, slit lamps are flanged, with which three-dimensional images of microscope robots or eyes can be. Furthermore, it is possible, for example, using a rotatable mirror arrangement an adjustment for near or To get macro shots.
