Definitions

  • the invention relates to a viewfinder for a studio camera, and to a studio camera provided with a viewfinder.
  • Studio camera viewfinders are hand-adjusted to allow the camera operator to have a good view on what is picked up by the camera.
  • viewfinders having an LCD display known for having a large viewing angle dependency of the display, it is very important that the camera operator continuously has a good view on the viewfinder display.
  • the viewfinder is provided with a pan and tilt mechanism that is to be operated by the camera operator, who for this purpose, has to remove his hands from the camera controls (sharpness, zooming, pan, tilt).
  • a studio camera comprising an image pickup unit for converting a scene into image signals, and a viewfinder for displaying the image signals on a viewfinder display, the viewfinder having a position adjustment mechanism for allowing a camera operator to have an optimal view on the viewfinder display, the position adjustment mechanism is automatically controlled so as to direct the viewfinder display to the camera operator.
  • Fig. 1 shows an embodiment of a studio camera in accordance with the present invention
  • Fig. 2 shows parts of the studio camera of Fig. 1 in more detail.
  • the studio camera SC comprises an image pickup unit PUU and a viewfinder VF.
  • the viewfinder VF has a position adjustment mechanism PAM to automatically direct a viewfinder display D to a camera operator CO.
  • the position adjustment mechanism PAM just has a tilt motor M.
  • the position adjustment mechanism PAM is controlled by a receiver REC that receives position information signals from a transmitter TRANSM unit mounted on a head H of the camera operator CO.
  • the transmitter unit TRANSM has a device for attaching the transmitter to the head H, and a proper transmitter T.
  • the viewfinder VF is provided with a (tilt) motor M which is controlled by a transmitter TRANSM, preferably an optical transmitter, mounted on the cameraman's head H, preferably in his headphone, in such a manner that the viewfinder display D is always directed to the camera operator's face.
  • a transmitter TRANSM preferably an optical transmitter
  • the viewfinder's position adjustment mechanism comprises a gyroscope to ensure that the viewfinder display stays directed to the camera operator's face even if the image pickup unit is moved.
  • any reference signs placed between parentheses shall not be construed as limiting the claim.
  • the word "comprising” does not exclude the presence of other elements or steps than those listed in a claim.
  • the invention can be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer. In the device claim enumerating several means, several of these means can be embodied by one and the same item of hardware.
