Patent number: 8711439Abstract: A scanner enables full productivity and individual image size detection, without user intervention for mixed size originals in both simplex and duplex scanning modes. The scanner provides high-productivity single pass scanning while preserving the image size for each of the document scanned. In addition, the scanner may support duplex scanning by adding a second image sensor, for example, in the document handler. Methods of scanning are also provided.Type: GrantFiled: June 9, 2009Date of Patent: April 29, 2014Assignee: Xerox CorporationInventors: Aron Nacman, Seth H. Groder, John C. Guarrera, Dawn Marie LaPietra, Whynn Victor Lovette, Daniel A. Mohabir, John F. Seward

Patent number: 7894094Abstract: A system and method to provide 180-degree rotation of image data at full throughput. The system includes a memory access controller that writes bursts of image data into a rotation buffer. The image data is then read out of the rotation buffer in the reverse order from which it was written to thereby accomplish rotation. By alternating the position in the rotation buffer in which the image data is written such that an image is either written into the buffer from top and read from the bottom or written into the buffer from the bottom and read out from the top, a one page rotation buffer of can be used to concurrently process two pages.Type: GrantFiled: September 22, 2004Date of Patent: February 22, 2011Assignee: Xerox CorporationInventors: Aron Nacman, Daniel A. Mohabir, Lisa M. Schlachter, Dawn M. Lapietra, James P. Guy, Brian R. Caffee

Patent number: 7852531Abstract: A system and method are provided for digital correction of a plurality of color channels and color image data. In color reproduction, a color image may be composed of a plurality of superimposed color channels in a color space. In order to assure the proper alignment of color channels and exemplary applications such as color printing, one or more of the plurality of color channels which compose a complete color image may be scaled to an output resolution, and corrected in order to ensure proper alignment and authentic reproduction of a color image. In place of a plurality of independent clocks, one for each channel, a single clock is provided for every channel, and additional unit is supplied to scale each channel according to independent characteristics.Type: GrantFiled: December 12, 2007Date of Patent: December 14, 2010Assignee: Xerox CorporationInventors: Aron Nacman, John Adam Handwork, Theresa M.

Patent number: 7768678Abstract: An embodiment generally relates a device for rotating images. The device includes an image memory configured to store an image and a plurality of buffers. The plurality of buffers are configured to interface with the image memory to read data words of the image from the image memory and to write rotated data words to the image memory. The device also includes a logic module configured to interface with the plurality of buffers and to micro-rotate and macro-rotate an image based on a selection of three orientations. The logic module is also configured to execute a read of data words from the image memory to a first buffer of the plurality of buffers, a rotation of a data word, and a write of rotated data words from a second buffer of the plurality of buffers to the image memory substantially simultaneously.Type: GrantFiled: May 15, 2006Date of Patent: August 3, 2010Assignee: Xerox CorporationInventors: Aron Nacman, William David Notovitz, Theresa Michelle Marconi, Brian Richard Caffee, Anthony Paul Lanza, Timothy M.

Patent number: 6778293Abstract: Multiple components of an image produced by an image output device including a raster output scanner are registered by delaying an output high addressable bit stream for a time following each raster start of scan. A multiplicity of error values are added resulting in a total error integer component and a factional component. Following the start of scan, a line sync generator delays for a number of first clock signals proportional to the integer component. After the delay, the line sync generator signals a buffer to input a video input byte. A parallel to serial shift register converts the input video byte into a high addressable bit stream. A delay register further delays the bit stream by the fractional component, which further refines where, along the raster, the bit stream will commence. Suitably, the system corrects for the errors in run time as the fast scan line is scanned.Type: GrantFiled: December 2, 1998Date of Patent: August 17, 2004Assignee: Xerox CorporationInventor: Aron Nacman

Patent number: 6754401Abstract: A system and method for selective scaling of an image by selective implementation of a window averaging processing technique or an interpolation processing technique. For enlargement scaling, the interpolation processor is implemented. For reduction scaling, the window averaging processor is implemented. For anamorphic scaling, the window averaging processor may be selected and implemented for reduction processing pursuant to a two-pass processing technique wherein the interpolator processing will be implemented thereafter. Image tags are provided for selective scaling of each area of an image according to the type of content of each area by selective implementation of a window averaging processing technique or an interpolation processing technique. The interpolation processor is implemented for line drawing areas of an image, and the window averaging processor is implemented for contone areas of the image.Type: GrantFiled: February 21, 2003Date of Patent: June 22, 2004Assignee: Xerox CorporationInventors: Aron Nacman, Ramesh Nagarajan, William A.

Patent number: 6424751Abstract: A system and method for reducing an image by receiving a scaling factor which defines a window. Input pixel intensities of the image are summed in real time as they are input and stored until all pixels within the window have been received. The sum is then divided by the number of pixels within the window which produces an average intensity. A pixel having the average intensity is output.Type: GrantFiled: September 23, 1998Date of Patent: July 23, 2002Assignee: Xerox CorporationInventors: Michael K. Carney, Ramesh Nagarajan, Anthony M.
