Abstract
A motion picture camera and cassette system is provided having at least one motion picture camera and several film cassettes containing an exposed and/or unexposed motion picture film. The film cassettes contain a storage device which stores at least the length of the exposed and/or unexposed motion picture film. The motion picture cameras have a device for exchanging data with the storage device of the film cassettes and sensing the exposed length of motion picture film. Changes in the exposed film length are transmitted by the data exchange device of the film camera to the storage device of the film cassettes.
Claims14
A motion picture camera cassette system comprising a motion picture camera, a film cassette containing at least one of an exposed and unexposed motion picture film, and an electronic data-processing device, wherein the electronic data-processing device is selectively connectable to at least one of said motion picture camera and film cassette, wherein the film cassette contains a storage device which stores an initial value representing a length of the at least one of exposed and unexposed motion picture film in the film cassette;
- the motion picture camera has an exchange device which exchanges data with the storage device of the film cassette;
- the motion picture camera has a detecting device which detects a length of motion picture film exposed by the camera;
- the camera has a microprocessor which based upon the initial value of the at least one of exposed and unexposed motion picture film in the film cassette and the amount of exposed film detected by the detector calculates a new value representing the length of the at least one of exposed and unexposed motion picture film in the film cassette;
- and wherein the data-exchange device of the motion-picture camera transmits the new value representing the length of the at least one of exposed and unexposed film in the film cassette into the storage device of the film cassette.
A motion picture camera cassette system comprising:
- a film cassette containing at least one of an exposed and unexposed motion picture film and a comprising a storage device;
- a motion picture camera comprising,
- a detecting device which detects a length of the motion picture film exposed by the camera,
- a microprocessor which based upon the initial value of the at least one of exposed and unexposed motion picture film in the film cassette and the amount of exposed film detected by the detector calculates a new value representing the length of the at least one of exposed and unexposed motion picture film in the film cassette, and
- an exchange device which exchanges data with the storage device of the film cassette;
- and
- an electronic data-processing device, wherein the electronic data-processing device is connectable to the motion picture camera, wherein the electronic data-processing device processes data output by the motion picture camera and outputs data to the motion picture camera, wherein the film cassette storage device stores an initial value representing a length of the at least one of exposed and unexposed motion picture film in the film cassette, and wherein the exchange device of the motion-picture camera transmits the new value representing the length of the at least one of exposed and unexposed film in the film cassette into the storage device of the film cassette.
