Description

Externe Neigungswinkelanzeige für Kameras External tilt angle display for cameras
Die Erfindung betrifft eine Kamera für Film-, Foto- und Videoaufnahmen, mit einem Kameragehäuse, mit einem Objek¬ tiv, mit einem Sucher und mit einem eine Schräglage des Kameragehäuses relativ zu einer die optische Achse und eine senkrecht zu dieser Achse und horizontal verlaufende Gerade enthaltenen Ebene anzeigenden Neigungswinkelsensor.The invention relates to a camera for film, photo and video recordings, with a camera housing, with an objective, with a viewfinder and with an inclined position of the camera housing relative to a straight line extending perpendicularly to the optical axis and a line perpendicular to this axis included inclination angle sensor.
Derartige Kameras werden entweder auf einem Stativ befe¬ stigt oder werden von freier Hand gehalten betätigt. Damit die Ausrichtung der Kamera nicht subjektiv auf das Beobach¬ tungsvermögen des Benutzers angewiesen ist, ist es bei ei¬ ner aus der DE 30 17 820 A1 bekannten Stereokamera vor¬ gesehen, Quecksilberschaltkontakte für die lageabhängige Verkantungsanzeige zu verwenden. Diese Verkantungsanzeige ist sehr speziell und nur für Stereokameras vorgesehen. Beispielsweise für Vermessungs- oder Architekturaufnahmen sind Schräglagen des Kameragehäuses relativ zur optischen Achse nachteilig und zu vermeiden. Aufgabe der vorliegenden Erfindung ist es, einfache, nach- rüstbare Mittel zu schaffen, mit denen eine Schrägausrich¬ tung einer Kamera vermieden werden kann.Such cameras are either attached to a tripod or are operated by a free hand. So that the orientation of the camera is not subjectively dependent on the user's ability to observe, it is provided in a stereo camera known from DE 30 17 820 A1 to use mercury switch contacts for the position-dependent tilting display. This tilt indicator is very special and only intended for stereo cameras. For example, for measurement or architectural recordings, inclined positions of the camera housing relative to the optical axis are disadvantageous and should be avoided. The object of the present invention is to provide simple, retrofittable means with which an oblique alignment of a camera can be avoided.
Gelöst wird diese Aufgabe dadurch, daß der Neigungswinkel¬ sensor in einem externen, mit dem Kameragehäuse verbindba¬ ren Bauteil untergebracht ist, das Bauteil eine elektrische Batterie beinhaltet und mit einer optischen Anzeige und/ oder einer akustischen Anzeige versehen ist. Zur Verein- fachung der Bedienung ist es vorgesehen, daß der elektroni¬ sche Neigungswinkelsensor über elektrische Leitungen mit dem Auslöser und dem Sucherbild des Suchers verbunden ist.This object is achieved in that the inclination angle sensor is accommodated in an external component which can be connected to the camera housing, the component contains an electric battery and is provided with an optical display and / or an acoustic display. To simplify operation, it is provided that the electronic angle of inclination sensor is connected to the trigger and the viewfinder image of the viewfinder via electrical lines.
Durch diese Maßnahmen kann jede Kamera mit einfachen Mit¬ teln nachgerüstet und unabhängig von den subjektiven Veran- lagungen des Benutzers exakt ausgerichtet und betätigt wer¬ den. Eine Schräglage des Kameragehäuses relativ zur Ebene der optischen Achse kann festgestellt und vermieden werden. Dabei spielt es keine Rolle, ob die Aufnahme im Hoch- oder Querformat gemacht werden soll. Auch bei Aufnahmen schräg auf- oder abwärts ist eine exakte Ausrichtung der Kamera relativ zu der auf das aufzunehmende Objekt gerichteten op¬ tischen Achse gewährleistet. Verkantungen und Verzerrungen in der Perspektive werden vermieden und die so gemachten Aufnahmen sind beispielsweise für Größenermittlungen ver- wendbar oder können für sog. Panoramaaufnahmen verwendet werden. Der Neigungswinkelsensor findet dabei vorteilhaf¬ terweise Aufnahme in einem Stativadapter. Weitere vorteilhafte Maßnahmen sind in den Unteransprüchen beschrieben. Die Erfindung ist in der beiliegenden Zeich¬ nung dargestellt und wird nachfolgend näher beschrieben; es zeigt:By means of these measures, each camera can be retrofitted with simple means and precisely aligned and actuated independently of the subjective dispositions of the user. An oblique position of the camera housing relative to the plane of the optical axis can be determined and avoided. It does not matter whether the picture should be taken in portrait or landscape format. Even when taking pictures diagonally upwards or downwards, an exact alignment of the camera relative to the optical axis directed at the object to be recorded is guaranteed. Tilting and distortion in the perspective are avoided and the pictures taken in this way can be used, for example, for size determination or can be used for so-called panorama pictures. The angle of inclination sensor is advantageously accommodated in a tripod adapter. Further advantageous measures are described in the subclaims. The invention is illustrated in the accompanying drawing and is described in more detail below; it shows:
