Definitions

  • 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.
  • 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.
  • 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.
  • the electronic angle of inclination sensor is connected to the trigger and the viewfinder image of the viewfinder via electrical lines.
  • 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:
  • FIG. 1 shows the front view, partly in section, of a camera
  • FIG. 2 shows an external inclination angle sensor according to the invention, accommodated in an intermediate piece, for connection to a camera according to FIG. 1.
  • the camera shown in FIG. 1 essentially consists of a camera housing 10 with a lens 11 and a viewfinder 12.
  • An electronic operator component 13 is accommodated in the housing 10 and can be fed, for example, by an also integrated electrical battery 14 .
  • the electrical battery 14 is connected to the operator component 13 via electrical lines 15 and this in turn is connected to a trigger 16 and a viewfinder 12 via electrical lines 15.
  • the user can observe a viewfinder image 17 in which a range finder display 19 and an exposure meter display 20 are provided as optical signals, for example as red-green signals, outside the recording area.
  • a switch 28 is assigned to the operator component 13, by means of which its operational readiness can be established or interrupted.
  • the camera housing 10 is provided with a tripod thread 21.
  • the tripod thread 21 can be connected to the electronic operator component 13 via an electrical line 15.
  • FIG. 2 shows a component 26 designed as an intermediate piece with an intermediate piece housing 29 in which an external inclination angle sensor 22 is accommodated.
  • an intermediate battery 29 also houses an electric battery 14 for keeping the operating voltage ready.
  • the component 26 is provided with a threaded bolt 23 with which it can be connected to the tripod thread 21 of the camera housing 10.
  • a tripod thread 27 is also provided, with which the component 26 can be screwed onto a tripod, not shown.
  • an external visual display 24 and / or an acoustic display 25 is provided.
  • the acoustic display 25 can be accommodated both in the camera housing 10 and in the component 26.
  • any camera can use such an external camera tion angle sensor 22 can be retrofitted.
  • the tripod thread 21 can be connected to the operator component 13 via an electrical line 15.
  • the flashlight shoe not shown in each camera, can be connected to the operator component 13 or directly to the viewfinder 12.
  • the component 26 and with it the external inclination angle sensor 22 can also be connected to the tripod thread 21 in the camera housing 10 without an electrical connection via the flashlight shoe (not shown) or via a threaded bolt 23.
  • the information coming from the inclination angle sensor 22 via the operator component 13 can be fed in as an inclination angle display in the form of LCs (Liquid Cristals) 18 or also as red-green displays.
  • LCs Liquid Cristals
  • the exact horizontal alignment for landscape format recordings or the exact vertical alignment for portrait format recordings can thus also be displayed in the viewfinder 12.

Abstract

Caméra pour film, photo et vidéo, comportant un boîtier de caméra (10) avec un objectif (11), un viseur (12) et un capteur d'angle d'inclinaison (22) indiquant l'inclinaison du boîtier de caméra par rapport à un plan contenant l'axe optique et une droite horizontale perpendiculaire à cet axe. Le capteur d'angle (22) est placé dans un composant externe (26) relié au boîtier de caméra (10). Le composant (26) contient une pile électrique (14) et est muni d'un système d'indication optique (24) et/ou acoustique (25).
