BESCHREIBUNG DER ERFINDUNGDESCRIPTION OF THE INVENTION

Funkgesteuerte Blenden-, Schärfen- und Brennweitenverstellung sowie Übertragung eines Impulses zur funkgesteuerten Schaltung des Kamera-Rotlichtes an Videokameras unter Einbeziehung des im Objektiv eingebauten Blende-, Schärfe- und Brennweitenstellmotors.Radio-controlled aperture, focus and focal length adjustment as well as transmission of a pulse for radio-controlled switching of the camera red light on video cameras, including the aperture, focus and focal length adjustment motor built into the lens.

Problem :Issue:

Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, Blende, Schärfe und Brennweite an professionellen Videokameras in Einsatzsituationen, in denen kein direkter Zugriff auf die Kamera möglich ist, (z.Bsp. beim Arbeiten mit einem sog. "Steadicam"-Stabilisierungssystem) funkgesteuert zu verstellen. Das gleiche gilt für das Ein- und Ausschalten des Kamera-Rotlichtes. Desweiteren müssen in diesen Situationen vorgewählte Blenden- und Schärfenwerte einstell- und abrufbar sein.The invention specified in the protection claim is based on the problem of adjusting the aperture, focus and focal length on professional video cameras using radio control in situations in which direct access to the camera is not possible (e.g. when working with a so-called "Steadicam" stabilization system). The same applies to switching the camera's red light on and off. Furthermore, preselected aperture and focus values must be adjustable and retrievable in these situations.

Lösung :Solution :

Durch einen Fernsteuersender werden Impulse übertragen, die in dem an der Kamera montierten Empfänger mit nachgeschalteter Elektronik Steuerspannungen erzeugen, die die im Objektiv serienmäßig eingebauten Motoren für Blende, Schärfe und Brennweite ansteuern. Empfänger und nachgeschaltete Elektronik werden elektrisch zwischen Kamera und Objektiv eingeschleift. Ebenso erfolgt die Übertragung Rotlicht-Schaltimpulses.A remote control transmitter transmits impulses that generate control voltages in the receiver mounted on the camera with downstream electronics that control the motors for aperture, focus and focal length that are built into the lens as standard. The receiver and downstream electronics are electrically looped between the camera and the lens. The red light switching impulse is transmitted in the same way.

Am Sender lässt sich darüberhinaus eine Vorrichtung in den Regelweg einschleifen, mit der mehrere frei wählbare Blenden- und Schärfewerte gespeichert und bei Bedarf abgerufen werden können. Darüberhinaus lassen sich Blende, Schärfe und Brennweite an dieser Vorrichtung auch über Handregler einstellen. Diese Schalteinrichtung kann, über drei 3-adrige Kabel mit dem Sender verbunden, auch über mehrere hundert Meter Entfernung den Sender ansteuern.A device can also be looped into the control path on the transmitter, with which several freely selectable aperture and focus values can be stored and called up when required. In addition, the aperture, focus and focal length can also be set on this device using a hand controller. This switching device, connected to the transmitter via three 3-core cables, can also control the transmitter from a distance of several hundred meters.

Vorteil :Advantage :

Im Gegensatz zu anderen Herstellern, die die Verstellung mit extern angesetzten Motoren realisieren, arbeitet die eingereichte Erfindung mit den im Objektiv serienmäßig eingebauten Motoren. Da die Steuerspannungen weltweit genormt sind, ist die Erfindung universell für alle Objektiv-Marken und Typen einsetzbar und darüberhinaus kleiner, leichter und preiswerter.In contrast to other manufacturers who implement the adjustment with externally attached motors, the submitted invention works with the motors built into the lens as standard. Since the control voltages are standardized worldwide, the invention can be used universally for all lens brands and types and is also smaller, lighter and less expensive.

Dipl.Ing.Michael Laufer, Nölkehof 6, 30459 Hannover SCHUTZANSPRÜCHE Dipl.Ing.Michael Laufer, Nölkehof 6, 30459 Hannover PROTECTION CLAIMS Funkgesteuerte Blenden- und Schärfen- und Zoomverstellun unter Einbeziehung des im Objektiv eingebauten Blenden-Schärfe- und Zoomstellmotors sowie funkgesteuerte Schaltung des Rotlichtes an Videokameras.Radio-controlled aperture, focus and zoom adjustment using the aperture, focus and zoom adjustment motor built into the lens as well as radio-controlled switching of the red light on video cameras. Weiterhin eine senderseitig installierbare Schalt- und Steuereinrichtung, mit der sich mehrere Blenden- und Schärfewerte speichern und aufrufen lassen oder Blende und Schärfe manuell steuern lassen.There is also a switching and control device that can be installed on the transmitter side, with which several aperture and focus values can be saved and called up or aperture and focus can be controlled manually. Die Steuerelektronik mit Funkfernsteuerempfänger und wird zwischen Objektiv und Kamera eingeschleift und verfügt über 4 Hauptfunktionen:The control electronics with radio remote control receiver is looped between the lens and the camera and has 4 main functions: 1. Zur Blendenverstellung wird funkgesteuert eine variable Steuerspannung von ca. 3,2 Volt bis ca. 6,4 Volt zur Ansteuerung des im Objektiv eingebauten Blendenstellmotors erzeugt.1. To adjust the aperture, a variable control voltage of approx. 3.2 volts to approx. 6.4 volts is generated via radio control to control the aperture adjustment motor built into the lens. Hierzu wird die Impulsbreite des Empfängerausgangssignales von der Steuerelektronik ausgewertet und eine entsprechende Gleichspannung erzeugt. Über Potentiometer ist obere (ca.6,4 Volt) und untere (ca.3,2 Volt) Schwellenspannung einstellbar. Darüberhinaus geht eine im Objektiv erzeugte Referenzspannung, die den Ist-Wert der Blende angibt, bei der Regelung zur Erzeugung der Steuerspannung ein.For this purpose, the pulse width of the receiver output signal is evaluated by the control electronics and a corresponding direct voltage is generated. The upper (approx. 6.4 volts) and lower (approx. 3.2 volts) threshold voltage can be set using potentiometers. In addition, a reference voltage generated in the lens, which indicates the actual value of the aperture, is used in the regulation to generate the control voltage. 2. Zur Schärfeverstellung wird funkgesteuert eine variable Steuerspannung von ca.3,2 bis ca.6,4 Volt zur Ansteuerung des im Objektiv eingebauten Schärfestellmotors erzeugt. Die Steuerspannung wird wie unter Punkt 1 beschrieben erzeugt.2. To adjust the focus, a variable control voltage of approx. 3.2 to approx. 6.4 volts is generated by radio control to control the focus adjustment motor built into the lens. The control voltage is generated as described under point 1. 3. Zur Brennweitenverstellung wir funkgesteuert eine variable Steuerspannung von ca.3,2 bis ca.6,4 Volt zur Ansteuerung des im Objektiv eingebauten BrennweitenverStellmotors durch die Steuerelektronik erzeugt. Die Steuerspannung wird wie unter Punkt 1 beschrieben erzeugt.3. To adjust the focal length, a variable control voltage of approx. 3.2 to approx. 6.4 volts is generated by radio control to control the focal length adjustment motor built into the lens by the control electronics. The control voltage is generated as described under point 1. 4. Das Rotlicht zur Signalisierung des Sendebetriebes der Kamera wird funkgesteuert ein- und ausgeschaltet.4. The red light that indicates the camera is transmitting is switched on and off via radio control. Eine Schalt- und Stelleinheit ist in den Regelweg des Senders einschleifbar und erlaubt das Abspeichern und Aufrufen von mehreren Blenden- und Schärfewerten sowie das Verstellen der Blende und Schärfe wahlweise auch über Handregler. Mit dieser Schalteinheit auch das Rotlicht der Kamera funkgesteuert geschaltet werden. Die Schalt und Stelleinheit wird über drei 3-adrige Kabel mit dem Sender verbunden und kann bis zu mehrere hundert Meter entfernt vom Sender diesen ansteuern.A switching and adjustment unit can be looped into the control path of the transmitter and allows the storage and recall of several aperture and focus values as well as the adjustment of the aperture and focus optionally via hand controller. With this switching unit, the red light of the camera can also be switched radio-controlled. The switching and adjustment unit is connected to the transmitter via three 3-core cables and can control it up to several hundred meters away from the transmitter.
