Patent number: 7907249Abstract: A film exposer has a modulator which modulates light from a light source and projects it onto a light-sensitive film guided continuously past the modulator. The modulator comprises a two-dimensional arrangement of elements which each project a specific quantity of light onto the film. A pixel entering the projection area of the modulator of the film on one side integrates the light which is projected onto the pixel by elements arranged in a row in the transport direction of the film. The quantity of light integrated by the pixel depends on how many elements are switched on, that is to say project light onto the film, while the film passes through the projection area of the modulator. The total quantity of the light to be integrated can be adjusted for each pixel by appropriate control of the elements respectively lying in a row in the transport direction of the film.Type: GrantFiled: August 3, 2005Date of Patent: March 15, 2011Assignee: GBVV Holdings S.A.R.L.Inventor: Klaus Anderle

Patent number: 3932032Abstract: A system is described for digital, as opposed to the usual analog, recording of a sound track in synchronism with a visual image on a motion picture film and automatically reproducing the sound in synchronism with the visual image. In one embodiment of the invention, a camera employs a linear array of light-emitting diodes across the sound track to enter a digital representation of the sound on the same frame as the synchronous visual image. The digital, specifically binary, signals which excite the light-emitting diodes are produced by analog to digital conversion of samples of the sound waveform. The binary representations are entered into shift registers at a uniform rate, and read out to the light-emitting diodes in a burst during the film advance interval immediately following shutter closure, thereby entering on the film track an optical record of all the binary pulses derived from sound produced during the just concluded frame interval.Type: GrantFiled: April 3, 1974Date of Patent: January 13, 1976Inventor: Stephen B.
