Patent number: 7333669Abstract: In processing a digital image to provide a desired grain appearance, a noise table is formed that represents noise magnitude vs. intensity of the image. A plurality of potential image processing paths are provided. Each path has one or more image transforms. The noise table is modified according to the image transforms in the respective image processing paths to provide a plurality of output noise tables. Noise metrics are generated from each of the output noise tables. The noise metrics each represent the appearance of the image processed by the respective image processing path. An input is then accepted designating one of the paths. The image is processed according to the designated image processing path to provide an output image having desired noise.Type: GrantFiled: January 18, 2005Date of Patent: February 19, 2008Assignee: Eastman Kodak CompanyInventors: Andrew C. Gallagher, Martin E. Oehlbeck, Nestor M. Rodriguez

Patent number: 7053935Abstract: An electronic color image capture system includes an optical section for separating an input image into its separate color content and directing the separate color content toward an imaging section, which generates a plurality of color image signals from the input image. The spectral responses of the optical section and the imaging section are selected so as to cascade together to provide all-positive, symmetrical system curves modeled upon red, green and blue color matching functions representative of the human visual system. The color matching functions are derived from three monochromatic light sources and contain no more than three positive lobes as well as one or more negative lobes, wherein the areas under the color matching functions determined by (a) summation of all negative lobes and (b) overlap between the green and red color matching functions are minimized.Type: GrantFiled: February 21, 2002Date of Patent: May 30, 2006Assignee: Eastman Kodak CompanyInventors: Marcelo de C. Guimaraes, Nestor M. Rodriguez

Patent number: 7034862Abstract: A sequence of electronically captured images are converted into modified images providing the appearance of images captured by a film reproduction system, where the film reproduction system is of the type that includes a motion picture negative film printed onto a motion picture print film that is displayed, or a reversal motion picture system in which a reversal film is displayed. After electronically capturing the images, the electronically captured image data is transformed into linearized exposure data, which is subsequently transformed with a linear function that emulates a film exposure of the film reproduction system. The exposure-corrected images are then transformed with a non-linear function that renders the exposure-corrected images with a tone scale of the film reproduction system, and the tonescale-corrected images are transformed with a linear function that emulates a film color look provided by the film reproduction system.Type: GrantFiled: November 14, 2000Date of Patent: April 25, 2006Assignee: Eastman Kodak CompanyInventors: Karleen M. Cirulli, John C. Brewer, Nestor M. Rodriguez

Patent number: 6995793Abstract: A sequence of motion images, captured by an image capture system such as a digital camera, are converted into a sequence of modified motion images providing the appearance of motion images captured by the same capture system and subsequently rendered in a post-processing stage to simulate a particular look. The method involves capturing a sequence of motion images using a full resolution image sensor system, then recording the full resolution unprocessed image signals, and providing the recorded full resolution unprocessed image signals to the post-production process, where the images will be subsequently rendered in a post-processing stage to simulate a particular look. Meanwhile, one or more image processing algorithms are applied in the image capture system to the unprocessed image signals to simulate the particular look rendered in the post-processing stage, and the simulated image signals are displayed as a sequence of modified images.Type: GrantFiled: November 14, 2000Date of Patent: February 7, 2006Assignee: Eastman Kodak CompanyInventors: Haithem Albadawi, Nestor M. Rodriguez

Patent number: 5793418Abstract: A process and system for forming a video image with a telecine transfer device is disclosed, the process comprising converting a photographic film image into video signals representative of the image with a telecine transfer device which uses a cathode ray tube flying spot scanner in combination with at least one dichroic beam splitting mirror to separate the light from the cathode ray tube into component spectral segments which are then detected by a light detector, wherein a filter is positioned between the dichroic mirror and the light detector to compensate for an inconsistent spectral distribution of light in at least one component spectral segment resulting from a varying angle of incidence of light originating from various positions of the cathode ray tube onto the dichroic mirrors, said filter reducing the magnitude of the range of spectral change due to the varying angle of incidence.Type: GrantFiled: August 28, 1996Date of Patent: August 11, 1998Assignee: Eastman Kodak CompanyInventors: Mitchell J.

The system includes: a) an infrared filter: b) means for moving the infrared filter into the optical path between the sound system light source and photo detector when a film having a dye only soundtrack is to be projected, and for moving the infrared filter out of the optical path when a film having a silver soundtrack is to be projected; c) a preamplifier; and d) means for switching the preamplifier into a circuit between the photo detector and the sound amplifier when a film having a dye only soundtrack is to be projected and out of the circuit when a film having a silver soundtrack is to be projected.Type: GrantFiled: May 17, 1994Date of Patent: January 9, 1996Assignee: Eastman Kodak CompanyInventor: Nestor M.
