Publication number: 20100280929Abstract: Disclosed herein is a method and system for determining a billing structure for outputting documents using an image processing apparatus. If image data of the document includes color pixels, a billing structure is determined for each page based on an amount of color coverage. The marked color pixel locations of the image data to be output in the device dependent space are counted. Each color pixel location comprises at least one color plane. In some cases, a ratio of the count of the marked color pixel locations to a maximum number of pixel locations may be used to determine the amount on the page. Processing and determining a billing structure based on image data in the device dependent space, irrespective of the amount of ink/toner or color planes used, avoids charging a customer for color print job when only a small amount of color pixels are printed.Type: ApplicationFiled: October 16, 2009Publication date: November 4, 2010Applicant: XEROX CORPORATIONInventors: David Fuller COFFEY, James B. Campbell, Rafael Diaz, David Sponable, Robert J. Zolla

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.

Patent number: 6930759Abstract: A printing method and apparatus (100) for pre-exposing a digital watermark along a length of photosensitive medium at the time of manufacture is disclosed. The printing apparatus has an illumination source (60) for providing an exposure illumination, first and second LCD spatial light modulators (90a, 90b) for modulating the exposure illumination to form first and second exposure patterns according to image data, combining optics providing a single output path for directing both first and second exposure patterns onto the photosensitive medium and transport means for providing, during exposure, lengthwise displacement of the photosensitive medium with respect to the output path. The first and second exposure patterns form, lengthwise along the photosensitive medium, a latent image with modulated stripes having a predetermined intensity corresponding to the exposure patterns.Type: GrantFiled: September 23, 2003Date of Patent: August 16, 2005Assignee: Eastman Kodak CompanyInventors: James E.

Patent number: 6917758Abstract: A method for obtaining an adjusted digital image which is compensated for a watermark exposure is described comprising: determining a first sensitometric response of a photographic media without a watermark exposure; determining a second sensitometric response of the photographic media with a watermark exposure; generating a look-up table (LUT) from the first and second sensitometric responses; and modifying a digital representation of an image which is to be printed onto the photographic media in accordance with the look-up table to produce an adjusted digital image. The adjusted digital image may be printed directly onto a final print photographic film that receives a watermark exposure, or may be printed onto a printing negative photographic film to produce a printing negative with an adjusted image, which adjusted image is then printed onto a final print photographic film that receives a watermark exposure.Type: GrantFiled: December 19, 2003Date of Patent: July 12, 2005Assignee: Eastman Kodak CompanyInventors: Robert J. Zolla, Paul W. Jones

Patent number: 6882356Abstract: A printing method and apparatus (100) for pre-exposing a digital watermark image onto a photosensitive medium (140) at the time of manufacture is disclosed. For exposure energy, the apparatus employs a single color light source (60) consisting of an array of LEDs. The LEDs are spatially modulated in intensity by means of a reflective LCD array (91). The photosensitive medium (140) may be compensated to allow such single color pre-exposure while avoiding hue shift and contrast loss. The exposure at the film may be increased by: employing partial frame illumination, pulsing the LEDs with high currents with short pulse durations and low duty cycles, employing two LCD devices (91, 92) to utilize both polarizations, and dichroically combining two LED (60, 61) arrays of slightly different wavelengths.Type: GrantFiled: February 11, 2003Date of Patent: April 19, 2005Assignee: Eastman Kodak CompanyInventors: James E.
