Patent number: 8670166Abstract: A method of automatic white balance adjustment for a scanner is described hereinafter. First, a light source provides a white light to make the scanner scan a document and get an initial image of the document. Secondly, red, green and blue chromatic values of a background color are obtained in the initial image. Next, a factor is calculated based on the chromatic values and a calibration value which is stored in a calibration sheet. Lastly, the scanner automatically adjusts a brightness ratio of the red, green and blue lights of the light source according to the factor, and then rescans the document to get a final image which has a processed background color. Therefore, the final image having the background color close to white is in favor of identification. Furthermore, the adjustment is executed in the process of the scanner rescanning the document so that the step of executing adjustment by software can be eliminated.Type: GrantFiled: April 24, 2012Date of Patent: March 11, 2014Assignee: Foxlink Image Technology Co., Ltd.Inventors: Chang-Hsien Sung, Chien-Shen Chien

Patent number: 8599452Abstract: An image reading apparatus includes an automatic document feeder, a first reading unit to read a first side of a document fed by the automatic document feeder and to function as a main reading unit, a second reading unit to read a second side of the document fed by the automatic document feeder; and a control unit to operate the first and second reading units in order to perform an ADF two-sided reading mode. The control unit determines a point in time when the main reading unit is changed, based on a frequency in use of the ADF two-sided reading mode, and changes the main reading unit to the second reading unit at the determined point in time.Type: GrantFiled: March 29, 2012Date of Patent: December 3, 2013Assignee: SAMSUNG Electronics Co., Ltd.Inventor: Young Min Kim

Patent number: 8587613Abstract: A document processing system for accurately and efficiently analyzing documents and methods for making and using same. Each incoming document includes at least one section of textual content and is provided in an electronic form or as a paper-based document that is converted into an electronic form. Since many categories of documents, such as legal and accounting documents, often include one or more common text sections with similar textual content, the document processing system compares the documents to identify and classify the common text sections. The document comparison can be further enhanced by dividing the document into document segments and comparing the document segments; whereas, the conversion of paper-based documents likewise can be improved by comparing the resultant electronic document with a library of standard phrases, sentences, and paragraphs. The document processing system thereby enables an image of the document to be manipulated, as desired, to facilitate its review.Type: GrantFiled: August 27, 2012Date of Patent: November 19, 2013Assignee: Pricewaterhousecoopers LLPInventors: Lever Wang, Glenn Ricart, Cynthia Ann Thompson, Keith Wishon, Sheldon Laube

Patent number: 8587843Abstract: An apparatus and a method for controlling a light source used for image reading according to a user activity are provided. The light source controller being coupled to a light source and configured to change the power of the light source from an OFF state to an ON state when a user activity signal having a first state is output, the user activity signal having the first state being assumed to be output when a user activity, other than an instruction to begin scanning, that is assumed to ultimately cause output of the image reading start signal has been performed on the image reading apparatus.Type: GrantFiled: May 7, 2008Date of Patent: November 19, 2013Assignee: Ricoh Company, Ltd.Inventors: Takashi Enami, Toyonori Shiho, Hiroaki Umezawa

Patent number: 8587833Abstract: A printing system is provided for enabling a consistent color job re-print comprising a plurality of image marking engines. The system includes printing a master test image document printed by at least a first image marking engine. The master test image can have a data glyph and a plurality of reference patches. The data glyph can record distinct job attributes and the plurality of reference patches can record color parameters of a desired output. The system further provides a scanner for scanning the master test image document. The data glyph can provide the job attributes of the master test image document and can generate set-up data therefrom. The reference patches can provide the color parameters of the master test image document and can generate set-up data therefrom.Type: GrantFiled: June 14, 2012Date of Patent: November 19, 2013Assignee: Xerox CorporationInventors: Daniel Bray, Aaron M.
