Abstract: A housing device for coaxial reels of motion picture film, intended to be associated with an optical block of a film camera is provided, including: a stage housing the reels and defining a space for guiding rollers for guiding the film in a loop between the reels and a rear presser intended to face a filming window of the optical block, each reel including two circular flanges for axially holding the film around a core; a main axis intended to cooperate with the cores; two secondary axes each supporting a film return idler and separating disks for separating the flanges of a reel; and a control unit for defining a relative motion between the secondary axes and the reels, between an idle position where the secondary axes are radially distant from the reels and an active position where the separating disks separate the periphery of the flanges in a determined region, fixed with respect to the housing device.

Abstract: An analysis method for cinematographic film uses a film scanner for converting the images of the film into video images, the film scanner having a calibration mode providing a standardized video reproduction of films and a manual mode allowing the operator to adjust the film scanner for improving the visual quality of the video images it produces.

Abstract: A movie film cassette comprises a light-tight casing containing an unexposed film reel and adapted to contain, after shooting, an exposed film reel. The reels and the film are positioned so that, in an operating position within a reception device associated with a movie camera, no moving element, located in the casing and contacting the film, is in contact with a fixed element of the casing.

Abstract: A cine camera employing interchangeable film magazines with displacement of the spindles of the film take-off and take-up reels, comprises an electric motor mounted on the body of the camera and of which the horizontal driven shaft is fast with a driving magnetic plate of a magnetic coupler which is housed in an opening in the body coaxial with the axis of the motor and of the shaft. The outer front face of the driving magnetic plate is substantially flush with the outer face of the body which is adjacent the outer face of the wall of the casing of the interchangeable magazine. The magnetic coupler comprises, in the magazine, a driven magnetic plate of which the axis merges with that of the driving magnetic plate. The driven magnetic plate is fast with a driving pinion and the driven magnetic plate and the driving pinion are mounted to rotate, in the magazine, about an axis which is merged with the axis of the drive motor.

Abstract: A camera system including a matte box assembly for use on cameras for supporting a plurality of filters, the matte box assembly including first and second support arms connected to and supporting separate modules of the matte box such that a rotating filter support module is rotatable independently from the other modules.
