Abstract
The invention relates to an electronic motion picture camera having an optical receiving system and a beam splitter which splits the receiving beam path into a taking beam path leading to an optoelectronic taking sensor and a viewfinder beam path leading to an optical viewfinder. The camera has an electronic display for the reproduction of an additional image. An optical vision mixer is arranged in the viewfinder beam path by which the taken image and the additional image can be directed in the direction of the viewfinder such that the taken image or the additional image, or the taken image and the additional image as a uniform image, can be observed in the viewfinder.
Claims19
An electronic motion picture camera comprising:
- an optical receiving system;
- an optoelectronic taking sensor;
- an optical viewfinder;
- a beam splitter, which splits a receiving beam path into a taking beam path leading to the optoelectronic taking sensor and a viewfinder beam path leading to the optical viewfinder;
- an electronic display, which reproduces an additional image;
- an optical vision mixer arranged in the viewfinder beam path, which directs a taken image imaged along the viewfinder beam path by the optical receiving system and the additional image reproduced by the electronic display in the direction of the viewfinder;
- a photodetector arranged in the viewfinder beam path, which measures the brightness of the taken image imaged by the optical receiving system in the viewfinder;
- and
- a brightness regulation device, which regulates the brightness of the additional image reproduced by the electronic display in dependence on the measured brightness of the taken image.

An electronic motion picture camera comprising:
- an optical receiving system, which images a taken image along a receiving beam path;
- an optoelectronic taking sensor;
- an optical viewfinder;
- a mirror aperture, which has a transmission region and a mirror-coated masking region, wherein the mirror aperture is adapted to direct the taken image imaged by the optical receiving system selectively along a taking beam path in the direction of the optoelectronic taking sensor if the transmission region is located in the receiving beam path, or along a viewfinder beam path in the direction of the optical viewfinder if the mirror-coated masking region is located in the receiving beam path;
- an electronic display, which reproduces an additional image;
- an optical vision mixer arranged in the viewfinder beam path, which directs a taken image imaged along the viewfinder beam path by the optical receiving system and the additional image reproduced by the electronic display in the direction of the viewfinder;
