Description
Einrichtung zum optischen Kopieren stereoskopisch aufgenommener Filmbildpaare Es ist bekannt, daß zur - Erzielung eines einwandfreien räumlichen Bildeindruckes bei der Betrachtung stereoskopischer Bildpaare der Abstand der Mitten der Okulare bzw. der Mitten der Betrachtungsfenster des Betrachtungsgerätes etwa gleich dem Augenab-stand von 65 mm gewählt werden muß.Device for optical copying of stereoscopically recorded film image pairs It is known that to - achieve a perfect spatial image impression When viewing stereoscopic image pairs, the distance between the centers of the eyepieces or the middle of the viewing window of the viewing device roughly equal to that Interpupillary distance of 65 mm must be selected.
Es werden jedoch auch Aufnahmekameras verwendet, bei denen der Bildmittenabstand diesen Augenabstand von 65 mm nicht unlvesentlich über- bzw. unterschreitet. Eine Überschreitung des normalen Maßes wird z. B. in allen den Fällen stattfinden müssen, bei denen bei der späteren Betrachtung,ein räumlicher Eindruck von Gegenständen erreicht werden soll, die z. B. weiter als i oo m von der Aufnahmekamera entfernt sind. Dies ist in der Regel der Fall bei der Aufnahme ausgedehnter Landschaften. Einer Unterschreitung :des Augenabstandes wird man dagegen bei Mikrostereoaufnahmen begegnen. Um nun von solchen Aufnahmen mit einem optischen Kopiergerät zwangsläufig bei .allen damit zu .erzielenden Abbildungsverhältnissen Kopien zu erhalten, bei denen der Abstand der Bildmitten einen vorgegebenen Wert, vorzugsweise- ,gleich dem normalen Augenabstand hat, sind gemäß der Eifindung beiden Projektionsobjektiven Ablenkkeile angeordnet, deren Neigung in Abhängigkeit von der Einstellung des Abbildungsverhältnisses durch Steuermittel, wie z. B. Kurvenscheiben, entsprechend dem für den Bildmittenabstand vorgesehenen Wert zwangsläufig veränderbar ist.However, recording cameras are also used in which the center-to-center distance This eye relief of 65 mm is not insignificantly above or below this. One Exceeding the normal level is z. B. must take place in all cases in the case of which, when viewed later, a spatial impression of objects is to be achieved, the z. B. farther than i oo m away from the recording camera are. This is usually the case when shooting extensive landscapes. A shortfall: the eye relief, on the other hand, is what you get with micro-stereo recordings to encounter. In order to get such recordings with an optical copier inevitably to receive copies of all reproduction ratios to be achieved with it where the distance between the image centers is a predetermined value, preferably equal to the normal eye relief, both projection lenses are according to the invention Deflection wedges arranged, their inclination depending on the setting of the imaging ratio by control means such as B. cams, corresponding to the image center distance intended value is inevitably changeable.
Bekannte Projektionskopiereinrichtungen gestatten zwar auch eine Umformung des Bildmittenabstandes beim Kopieren, z. B. durch Querverschiebung der Projektionsobjektive, jedoch war hier keine zwangsläufige Abhängigkeit von der Einstellung des Abbildungsverhältnisses vorgesehen. Die Verwen-Known projection copying devices also allow reshaping the image center distance when copying, e.g. B. by shifting the projection lenses laterally, however, there was no inevitable dependence on the setting of the imaging ratio intended.
