Patent number: 4974096Abstract: A virtually transparent magnetic layer is included as an additional layer in a color negative film. Information exchange between various users of the film--such as the camera user, the dealer, and the photofinishers film-to-video printer--is carried via plural longitudinal magnetic tracks on the film, each track being dedicated to the writing and reading of a predetermined set of related parameters. The photofinisher-dedicated track locations fill the exposed image area of each frame. The camera tracks lie along the edges of the film between the film perforations, the preforations being widely spaced for this purpose. All data, such as cropping, zooming, rotating or character superposition instructions, is recorded as individual pieces of information identified by virtual data identifiers to enable the film-to-video printer to quickly access and execute such instructions by altering the video signal produced from each frame of the developed film.Type: GrantFiled: November 15, 1989Date of Patent: November 27, 1990Assignee: Eastman Kodak CompanyInventor: Michael L.

Patent number: 4307946Abstract: Flutter in an audio signal recorded on a magnetic tape is reduced by sampling the audio at a rate determined by the frequency of a reference signal also recorded on the tape, reading the samples into respective cells of a memory, and reading out respective cells of the memory at a substantially constant rate that is independent of rapidly changing short duration variations in tape speed. The read-out rate is isolated from tape speed by introducing a time delay between the read-in and read-out of the same sample, the amount of the delay changing in accordance with differences in speed between the tape and a fixed reference. Changes in the delay between read-in and read-out of the same sample generate an error signal that is used to control the speed of the capstan motor that drives the tape past a transducer.Type: GrantFiled: July 7, 1980Date of Patent: December 29, 1981Assignee: Polaroid CorporationInventors: William R.

Patent number: 4294523Abstract: This invention utilizes a series of two-dimensional photographs of successive cross-sections of an object. The photographs are arranged on a film strip in the order in which the successive sections appear in the object. The film strip is transparent and is intermittently illuminated as the successive frames of the film strip move across an optical path. A projection screen in the optical path is moved with respect to the optical path so that as each successive photograph is illuminated, that photograph is projected onto the screen at a successive position and so that each photograph as projected on the screen appears more remote from an observer than the preceding one. Thus there is formed on the screen a series of images which appear to an observer having persistence of vision to be a composite three-dimensional imgage. The illuminating means may omit the illumination of certain photographs of the series, so that only selected photographs are reproduced on the screen.Type: GrantFiled: October 19, 1979Date of Patent: October 13, 1981Assignee: The Zyntrax CorporationInventors: Edward A.

Patent number: 4194817Abstract: The user of a motion-picture camera selects between motion-picture and single-exposure operation, and presses a release member to initiate shooting, letting go of it to terminate motion-picture shooting. Each time the user lets go of the release member, an internal device provides an interrupt-transport marking alongside the just exposed film frame, or phase shifted relative thereto. Alternatively, the interrupt-transport marking is provided the next time the user presses the release member. In this way, the terminal frame of each motion-picture scene, and each and every one of the interspersed single-exposure shots, is provided with an interrupt-transport frame marking. Thus, if the film is run through a reproducing apparatus provided with a marking detector, detection of each interrupt-transport marking during motion-picture reproduction causes the terminal frame of each motion-picture scene, and also each one of the still shots, to be persistently reproduced as a still image.Type: GrantFiled: October 10, 1978Date of Patent: March 25, 1980Assignee: AGFA-Gevaert, A.G.Inventors: Frank Staudacher, Otto Stemme, Peter Lermann, Werner Went, Volkmar Stenzenberger, Eberhard Herzig, Friedrich Stumpf, Thomas Scheller, Jurgen Sylla, Friedrich Winkler, Johann Zanner

Patent number: 3958872Abstract: A motion picture camera of the type having an electrically magnetically operated release. The electric circuit includes a drive circuit and a release circuit as well as a signal circuit connected between the drive circuit and the release circuit. The drive circuit includes an electric motor for driving the film and a normally open drive switch all connected in series with the current source. The release circuit includes a release magnet having an armature and an exciting coil. The armature operates a normally open release switch for closing it upon energization of the exciting coil. The release switch and exciter coil are connected in series with the source. Finally, the signal circuit includes an electro-optic indicator such as an incandescent lamp or light-emitting diode connected in parallel with the exciter coil of the magnet and in series with the motor. As a result, the indicator lights up upon closing of the release switch to produce a light mark on the film before the motor begins to drive the film.Type: GrantFiled: October 7, 1974Date of Patent: May 25, 1976Assignee: Braun AktiengesellschaftInventor: Johann Roth

Patent number: 3945718Abstract: A switch adapted to cooperate with the pull-down claw of a silent movie camera for transmitting an electrical signal each time a frame of movie film is advanced past the shutter of the camera includes an insulating base adapted to be positioned within the film receiving compartment of a movie camera so as to fit around the film gate, the base having a grounding contact arm engaging the gate so as to be grounded through the camera and a contact finger insulated from the gate and disposed for intermittent engagement with the reciprocating pull-down claw which serves to close the switch each time a frame of film is advanced past the shutter.Type: GrantFiled: July 8, 1974Date of Patent: March 23, 1976Inventor: John D. Werner

Patent number: 3944348Abstract: If a cine film is to be projected to the accompaniment of a sound track on a separate tape it is necessary to cheek that the film and the sound track are correctly coordinated. This is ensured by reading a code mark from the sound track and using it to slow or stop the motion of the film. The point at which the film motion is slowed or stopped is used to evaluate the relative position of the film with respect to the sound track and thus check that correct coordination is present. This evaluation may take place visually or automatically. In the latter case the prolonged presence of a correlation marking on the film in a sensing position can be used to signal the existence of correlation whereas the absence of such marking may energize a warning lamp or deactivate the film drive.Type: GrantFiled: November 8, 1973Date of Patent: March 16, 1976Assignees: Karl Vockenhuber, Raimund HauserInventor: Otto Freudenschuss

Patent number: RE30278Abstract: A special effects system for simulating physical sensations in an audience during the presentation of a motion picture. Relatively high intensity, very low frequency random noise is acoustically coupled to a theater space to produce psychological and physiological sensations, much as earthquake movements, in the audience. The special effects are controlled by a control sub-channel which is either frequency multiplexed onto a conventional optical audio track or, in a magnetic stripe film format, the control sub-channel is placed on an accompanying optical track. The presence and amplitude of two control frequencies in the sub-channel are detected and logically combined, providing four separate digital function control signals and two analog control signals which are variable in amplitude.Type: GrantFiled: May 19, 1978Date of Patent: May 20, 1980Assignee: MCA Systems, Inc.Inventors: Richard J. Stumpf, Waldon O. Watson, Robert J. Leonard
