Abstract

The stereoscopic camera has two lenses, two shutters and two aperture sets, where the shutters (MV1, MV2) are operated by electromagnetic means. Both are connected to an electronic control device (SE). The aperture adjusters (MB1, MB2) are likewise operated electromagnetically, and both are connected to the control system (SE). The control device sets the opening duration of the shutters according to the setting of the aperture.

Description

Die Verschlüsse von Monokameras werden mechanisch betätigt. Die dazu erforderliche Energie wird entweder einem Federkraftspeicher entnommen oder von einem Elektromotor oder -magnet geliefert, die von einer Steuerelektronik gesteuert werden. Bei Stereokameras müssen beide Verschlüsse gleichzeitig betätigt werden. Hierzu wird bei bekannten Stereokameras eine Gestängekupplung der beiden Verschlüsse verwendet. Stereokameras mit elektromechanischer Betätigung der Verschlüsse sind nicht bekannt. Man könnte eine derartige Stereokamera aus zwei Monokameras zusammenbauen und die dazugehörigen Steuerelektroniken gemeinsam mit dem Auslöser betätigen. In diesem Fall benötigt man zwei Steuerelektroniken. Die Toleranzen der beiden Elektroniken könnten eine nicht exakte gleichzeitige Öffnung und Schließung der Verschlüsse zur Folge haben.The locks of mono cameras are operated mechanically. The the energy required for this is either a spring energy store taken from or supplied by an electric motor or magnet that be controlled by control electronics. With stereo cameras both locks must be operated simultaneously. To do this in known stereo cameras, a linkage coupling of the two Closures used. Stereo cameras with electromechanical Operation of the closures are not known. You could be one assemble such a stereo camera from two mono cameras and the associated control electronics together with the trigger actuate. In this case two control electronics are required. The Tolerances of the two electronics could not be exact simultaneous opening and closing of the closures to have.

Es hat sich also die Aufgabe gestellt, eine preisgünstige Stereokamera mit synchroner Öffnungszeit der beiden Verschlüsse zu schaffen. Diese Aufgabe wird mit den im Anspruch 1 angegebenen Mitteln gelöst. So it was the task of an inexpensive one Stereo camera with synchronous opening time of the two shutters create. This object is achieved with those specified in claim 1 Means solved.  

Die Erfindung wird nun anhand eines Ausführungsbeispiels beschrieben.The invention is now based on an embodiment described.

In der Zeichnung sind die für die Erfindung wesentlichen Teile einer Stereokamera dargestellt.In the drawing are the essential parts for the invention shown a stereo camera.

Es ist eine einzige Steuerelektronik SE vorgesehen, die mindestens einen Eingang aufweist, an dem ein Auslöser A angeschlossen ist. Die Steuerelektronik hat mindestens einen Ausgang P1 an den zwei Schrittmotoren MV1 und MV2 angeschlossen sind, die je einen Verschluß der Stereokamera betätigen. Die Steuerelektronik kann auch einen zweiten Eingang BE haben, an dem eine Blendeneinstellvorrichtung angeschlossen ist. In diesem Fall ist ein zweiter Ausgang P2 der Steuerelektronik zur Einstellung von zwei Schrittmotoren MB1 und MB2 vorgesehen, die je eine Blende der Stereokamera betätigen. Durch den Anschluß der Schrittmotoren für die Verschlüsse an eine einzige Steuerleitung ist sichergestellt, daß die beiden Verschlüsse, abgesehen von vernachlässigbaren Toleranzen der Verschlüsse selbst, synchron öffnen und schließen. Die Offenzeit der Verschlüsse kann in bekannter Weise von der Einstellung der Blendeneinstellvorrichtung bestimmt werden.A single control electronics SE is provided, which at least has an input to which a trigger A is connected. The control electronics has at least one output P1 on the two Stepper motors MV1 and MV2 are connected, each one Press the lock on the stereo camera. The control electronics can also have a second input BE, at which one Aperture adjuster is connected. In this case it is a second output P2 of the control electronics for setting two Stepper motors MB1 and MB2 are provided, each with an aperture of Operate the stereo camera. By connecting the stepper motors for the closures to a single control line are ensured, that the two closures, apart from negligible Tolerances of the closures themselves, open and close synchronously. The opening time of the closures can be known from the Setting the aperture setting device can be determined.
