Patent number: 5096286Abstract: A method is disclosed whereby a motion picture projector is equipped to operate at two or more different speeds, such as 24 and 30 frames per second. It is envisioned that different parts of a motion picture may be recorded at different frame rates, to variably impart a highly intense effect upon the audience, expanding the parameters of creative control for the producer of the film. In operation, the method described facilitates switching between these different frame rates, both during the presentation of a single motion picture and between pictures. Cue signals recorded onto the film actuate the change in speed. The projector is automatically set to switch operation into a different speed, and the frames of the film that will be shown during the transitional period are prepared to give the audience the impression of a smooth transition between speeds.Type: GrantFiled: March 7, 1990Date of Patent: March 17, 1992Inventor: Robert C.

Patent number: 4158487Abstract: My invention relates to photographing scenes with standard motion picture photographic equipment where multiple views of a subject are photographed while the subject rests on a moving turntable and the stationary camera has its optical axis pointed at the turntable rotation axis or where the subject is stationary and the camera effectively moves in an arc about an axis located between the camera and scene.The surface of the processed film (or other appropriate media) is arrayed in a vertical plane and constrained to move horizontally around a portion of a circle. Film images are scanned by a light source and radially projected in a direction away from a vertical rotation axis. Concentric with the vertical axis are the semi-specular screen of radius R and the scanning projector circle of radius close to R/3. The screen reflects projected light in a horizontal plane and scatters projected light in a vertical plane.Type: GrantFiled: February 17, 1978Date of Patent: June 19, 1979Inventor: Robert B. Collender

Patent number: 4110017Abstract: There is disclosed a method for generating a low-frequency sound program for play during the performance of a motion picture film to produce a physical effect on the theater audience. Rather than to use random low-frequency noise or some other low-frequency source which is unrelated to the audible sound program, the low-frequency program is derived by shifting down in frequency a selected portion of the audible sound program. The final low-frequency program contains frequency components below 40 Hz, at least 50% of the total energy of which is derived from the shifted-down audible program. By so harmonically relating the audible and low-frequency programs, the audio/visual and vibrational sensations are perceived in a less disjointed fashion.Type: GrantFiled: June 3, 1977Date of Patent: August 29, 1978Assignee: Warner Bros. Inc.Inventors: Thomas L. McCormack, Albert P. Green

Patent number: 4089597Abstract: My invention relates to photographing scenes with standard motion picture photographic equipment in which there is a relative motion between the scene and camera with the purpose of stereoscopic viewing of the motion picture or stationary reproduction without the need for viewing aids at the eyes. The system is compatible with scenes photographed without this relative motion, where with the reproduction is viewed in conventional two dimensions.The surface of the processed film (or other appropriate media) is arrayed in a vertical plane and constrained to move horizontally around a segment of a circle of radius 2R. At the center of the film circle is a film motion compensator which can be a multi faceted mirror drum of radius R. The film is rapidly scanned about the center of this circle by a light source directed through the film and toward the center of the mirror drum.Type: GrantFiled: March 11, 1976Date of Patent: May 16, 1978Inventor: Robert Bruce Collender

Patent number: 3973839Abstract: 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: December 30, 1974Date of Patent: August 10, 1976Assignee: MCA Systems, Inc.Inventors: Richard J. Stumpf, Waldon O. Watson, Robert J. Leonard

Patent number: 3967888Abstract: Image display from a continuously moving image carrier with the aid of a repeatedly advanced and reset optical compensator is improved by omitting the traditional compensator bias spring and resetting the compensator with electric power pulse doublets. A substantially constant driving torque may be provided for the compensator in proportion to a damping term of the compensator equation of motion. An electric bias may alternatively or additionally be provided for biasing the compensator during image display against the direction of advance motion. Decelerating power may selectively be applied to the compensator to prevent or correct overshooting in the advance direction.Type: GrantFiled: November 13, 1970Date of Patent: July 6, 1976Assignee: Bell & Howell CompanyInventors: Joseph H. Lancor, Jr., deceased, Leonard A. Ferrari
