ABSTRACT:
BACKGROUND OF THE INVENTION
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. Especially for 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. To adjust the viewfinder orientation, 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).
SUMMARY OF THE INVENTION
It is, inter alia, an object of the invention to facilitate a camera operator's work. To this end, primary aspects of the invention provide a camera viewfinder unit, a studio camera, and a head-mountable transmitter as defined in the independent claims. Advantageous embodiments are defined in the dependent claims.
In a studio camera in accordance with the present invention, 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.
These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
