Patent number: 7782347Abstract: A printing apparatus (100) for printing digital images onto a photosensitive medium (140) employing, for exposure energy, a light source (20) that uses various arrays of LEDs (32). The printing apparatus (100) may form the print image using sequential modulation, one color at a time, or by applying all colors simultaneously. Arrangements of discrete LEDs (32) may include high-intensity devices configured with collector cones (41) arranged as a multicone structure (141), with parabolic reflectors (65), or collimating lenses (36). Large area LEDs (46) may alternately be used, arranged on an angled mounting surface (64), for example.Type: GrantFiled: January 22, 2008Date of Patent: August 24, 2010Assignee: Eastman Kodak CompanyInventors: Martin E. Oehlbeck, Richard L. Druzynski, Robert J. Zolla, James E. Roddy

Patent number: 6980280Abstract: A two level image writer (10) forms an image from digital data onto a photosensitive medium. A first level illumination system has a first source (20) for emitting a first polarized light beam having a first color; a second source (22) for emitting a second polarized light beam having a second color; and a third source (26) for emitting a third polarized light beam having a third color. A fold mirrors directs each beam to a second level. Three polarizing beamsplitters (73, 75, 77) on the second level receive the polarized beams from the fold mirrors and isolate polarization states of each of the first, second, and third polarized light beam. Three spatial light modulators (90, 95, 97) on the second level modulate the first, second, and third polarized light beam from the polarizing beamsplitter prisms to form an array of image pixels according to said digital data. A diechroic combiner (86) combines the three modulated light beams.Type: GrantFiled: October 12, 2001Date of Patent: December 27, 2005Assignee: Eastman Kodak CompanyInventors: James E. Roddy, Robert J. Zolla, Richard L. Druzynski

Patent number: 6778290Abstract: A method of printing image frames from a digital image file of a motion picture includes providing a two-dimensional LCD modulator having predetermined pixels which selectively can be activated so as to respond to incident light to provide monochromatic visual images; responding to the digital image file to activate the pixels in the LCD modulator to provide visual image planes corresponding to each frame of the motion picture; and moving a photosensitive medium past the LCD modulator to illuminate different portions of such medium from the illuminated LCD modulator to record the image planes on such medium.Type: GrantFiled: August 23, 2001Date of Patent: August 17, 2004Assignee: Eastman Kodak CompanyInventors: Martin E. Oehlbeck, Rockwell N. Yarid, Richard L. Druzynski

Patent number: 6478426Abstract: A pin-registered film transport assembly provides an interlacing motion for moving and guiding a photographic film through a film gate. The assembly includes a first carriage mounted for movement parallel to a direction of film travel and a first pin assembly including a first pair of registration pins which are engageable in oppositely disposed perforations of the film, where the first pin assembly is mounted on the first carriage for movement perpendicular to the direction of film travel for engaging and disengaging the film perforations. The assembly also includes a second carriage mounted for movement parallel to the direction of film travel and a second pin assembly including a second pair of registration pins which are engageable in oppositely disposed perforations of the film, where the second pin assembly is mounted on the second carriage for movement perpendicular to the direction of film travel.Type: GrantFiled: September 21, 2000Date of Patent: November 12, 2002Assignee: Eastman Kodak CompanyInventors: Richard L.

Publication number: 20020125287Abstract: A perforated filmstrip transportation and registration system (100) and method provide a substrate in the form of a rotating drum (104) with vacuum holes (106) to allow an internally produced vacuum to act upon an engaged filmstrip (102). The rotating drum (104) has a number of registration-tension pin pair assemblies (216) that register and subsequently advance a filmstrip (102) at the 3 o'clock position in a registration mode (FIGS. 2 and 3), and are ready to be inserted in filmstrip perforations (208) when they approach the 3 o'clock position in a load mode (FIG. 4). The registration-tension pin pair assemblies (216) each contain a registration pin (220) and a tension pin (230) which are sized small enough to fit into filmstrip perforations (208) without interference, and which move away and towards each other in the nature of scissors blades in the preferred embodiment.Type: ApplicationFiled: January 8, 2001Publication date: September 12, 2002Applicant: Eastman Kodak CompanyInventors: Richard L. Druzynski, Jeffery R. Hawver
