Patent number: 6476404Abstract: When color image information including silver image information is photoelectrically read, the deterioration of image quality caused by a silver image is corrected to thereby obtain a high-quality image. In an image reading apparatus 100 for reading an image on a color silver salt photosensitive material in which silver halide and/or developing silver remains, there are provided: a CCD 113 for photoelectrically reading the image on the photosensitive material F in accordance with the spectral sensitivity of the photosensitive material F; and a color correcting portion 121 for correcting the deterioration of image quality caused by silver halide and/or developing silver for each of the color outputs of the CCD 113.Type: GrantFiled: October 16, 1998Date of Patent: November 5, 2002Assignee: Fuji Photo Film Co., Ltd.Inventor: Setsuji Tatsumi

Patent number: 5972575Abstract: Methods of selectively silvering photographic materials. A method for selective reflective silvering of color negative photographic materials, whereby an attractive image comprising reflective silver, black, and full color areas may be obtained, comprises the steps of developing the materials using a conventional color developer, applying a reflective silvering bath, and removing silver from selected areas of said materials. A method for selective reflective silvering of color positive photographic materials comprises the steps of developing said materials using a conventional color developer, applying a reflective silvering bath, and removing silver from selected areas of said materials.Type: GrantFiled: March 20, 1998Date of Patent: October 26, 1999Inventor: Victoria Cabezas

Patent number: 5709972Abstract: A generalized grain ruler incorporating a plurality of uniform patches representing a range of granularities, each patch being a perceptually distinct representation of graininess spaced at perceptually uniform intervals and recorded in an increasing sequence of graininess. A method for producing a generalized grain ruler for the measurement, by comparison of, grain in a reference imaging system generated image, comprising, the steps of:a) generating a set of random numbers for each image component;b) filtering each set of random numbers to alter the Wiener spectrum to result in a filtered set of random numbers that look as if they were generated by the reference photographic system; andc) delivering the filtered set of random numbers to an output device that renders them into an image which is the generalized grain ruler.Type: GrantFiled: November 19, 1996Date of Patent: January 20, 1998Assignee: Eastman Kodak CompanyInventors: Robert Everett Cookingham, Paul James Kane

Patent number: 5571663Abstract: A silver halide light-sensitive material comprising a support having thereon at least four silver halide emulsion layers having different color sensitivity, wherein three layers of the silver halide emulsion layers each contains a specific coupler and the other silver halide emulsion layer contains coupler(s) capable of correcting colors so as to provide a substantially black color having a transmission density of 2.5 or more when all couplers on the support are reacted. A color filter comprising blue, green, red and black parts prepared by subjecting the above-described silver halide light-sensitive material to pattern exposure, color development, bleach-fixing and water washing.Type: GrantFiled: July 5, 1995Date of Patent: November 5, 1996Assignee: Fuji Photo Film Co., Ltd.Inventor: Hiroyuki Hirai

Patent number: 4678740Abstract: A photographic matte for use in traveling matte photography is formed by recording a separation of a first screen-color separation of an image on a first film layer and recording a separation of a different second color on a second layer. Preferably, the second color is complementary to the screen color. One layer is developed to form a positive image and the other to form a negative image, these images reinforcing each other. One image is formed by black dye, using a coupler and a color developer and the other is formed by a black dye destruct technique in which the developed portion of the silver halide emulsion is removed. According to another aspect of the invention, a matte of increased density can be formed without commensurate image growth by combining a black dye image with a silver image.Type: GrantFiled: April 29, 1985Date of Patent: July 7, 1987Inventor: James N. Catania
