Patent number: 6856355Abstract: A color scannerless range imaging system comprises four component systems, including an illumination system, an image capture device, an optical assembly and a controller for interconnecting and controlling the component systems. The illumination system separately illuminates a scene with modulated and unmodulated illumination, while the image capture device is positioned in an optical path of the reflected illumination from the scene for capturing a plurality of images thereof, including (a) at least one image of the reflected modulated illumination, whereby the modulation of the reflected modulated illumination incorporates a phase delay corresponding to the distance of objects in the scene from the range imaging system, and (b) at least one color image of the reflected unmodulated illumination.Type: GrantFiled: November 30, 1999Date of Patent: February 15, 2005Assignee: Eastman Kodak CompanyInventors: Lawrence A. Ray, Louis R. Gabello, Kenneth J. Repich

Patent number: 6778277Abstract: Apparatus for measuring deflection of a film in a film gate having an aperture illuminated by a primary light source having an output spectrum, includes: a) a reflective photonic probe mounted in the film gate, the reflective probe having at least one optical fiber; b) a measurement light source coupled to reflective photonic probe and emitting a wavelength of light outside of the primary light source's spectrum; c) a photodetector coupled to the reflective photonic probe; d) a narrow pass optical filter located between the photodetector and the reflective photonic probe, the narrow pass filter passing the light from the measurement light source and blocking the light from the primary light source; and e) signal processing electronics connected to the photodetector for producing a signal representing the motion of the film perpendicular to the plane of the film.Type: GrantFiled: May 24, 2001Date of Patent: August 17, 2004Assignee: Eastman Kodak CompanyInventors: Michael A. Marcus, Kenneth J. Repich

Patent number: 6588904Abstract: A system for compensating for film flutter in a motion picture film projector during projection of a motion picture film comprising multiple film image frames is described, the system comprising sensing the position of film image frames in a film gate of the projector relative to the focal plane of the projection lens assembly of the projector as the film image frames are being projected, and correcting the position of the film in the film gate of the projector or the position of the focal plane of the projection lens assembly to reduce the distance between the film image and the focal plane of the projection lens assembly as the film image frames are being projected, wherein the correction of the position of an individual film image frame in the film gate or that of the position of the focal plane of the projection lens assembly during projection of the individual frame image is based on the actual sensed position of the individual film image frame in the film gate, or on the position of a previously projectType: GrantFiled: October 18, 2001Date of Patent: July 8, 2003Assignee: Eastman Kodak CompanyInventors: Roger A. Morton, Christopher L. Dumont, Kenneth J. Repich, Alan T. Brewen

Publication number: 20030021599Abstract: A scannerless range imaging system includes an illumination system and an electromechanical light modulator. The illumination system illuminates objects in the scene with modulated illumination of a predetermined modulation frequency, and the modulated illumination reflected from objects in the scene incorporates a phase delay corresponding to the distance of the objects from the range imaging system. The electromechanical light modulator, which is positioned in an optical path of the reflected illumination, operates at a reference frequency that corresponds to the predetermined modulation frequency and accordingly modulates the modulated illumination reflected from the object, thereby generating a phase image from the interference between the reference frequency and the reflected modulated illumination.Type: ApplicationFiled: July 27, 2001Publication date: January 30, 2003Applicant: Eastman Kodak CompanyInventors: John C. Brazas, Louis R. Gabello, Marek Kowarz, Lawrence A. Ray, Kenneth J. Repich

Patent number: 6501530Abstract: A motion picture film projector illumination system (100) for minimizing film buckle comprises a light source (405) for producing a beam of light (416). Beam shaping optics (411) focus the light beam onto a film through an aperture (408) having an aperture opening (410) corresponding to a film frame (324). A secondary beam steering optics (465) directs stray light around edges of the aperture to illuminate film edge to frame edge areas (446).Type: GrantFiled: November 30, 2000Date of Patent: December 31, 2002Assignee: Eastman Kodak CompanyInventors: Andrew F. Kurtz, Joshua M. Cobb, Kenneth J. Repich
