Publication number: 20120236377Abstract: A system including a reading device that reads an image from a document and a control device that controls the reading device is disclosed herein. The control device includes a processor and a memory storing computer-readable instructions. The computer-readable instructions instruct the processor to determine whether a read image read by the reading device comprises a table image. The computer-readable instructions instruct the processor to generate a first file in a first file format when the processor determines that the read image comprises the table image. The computer-readable instructions instruct the processor to generate a second file in a second file format when the processor determines that the read image does not comprise the table image. The second file is different from the first file. The second file format is different from the first file format. Computer-readable media storing the computer-readable instructions and corresponding methods also are disclosed herein.Type: ApplicationFiled: March 15, 2012Publication date: September 20, 2012Inventor: Shinsuke KAIGAWA

Publication number: 20120236376Abstract: A scanning apparatus capable of switching a scanning background includes a pair of glass plates, a pair of background boards pivoted to the glass plates and a driving mechanism. The glass plates are disposed in a frame and overlapped with each other. The two glass plates define two scanning areas face to face. A portion of the frame adjacent to an outer surface of the glass plate defines a first color area of the scanning background corresponding to the scanning area. One background board is positioned above one glass plate, and the other background board is positioned under the other glass plate and away from the one background board. Each background board defines a second color area of the scanning background corresponding to the scanning area. The driving mechanism mounted in the frame drives the background boards to turn over with respect to the corresponding glass plates.Type: ApplicationFiled: December 9, 2011Publication date: September 20, 2012Applicant: FOXLINK IMAGE TECHNOLOGY CO., LTD.Inventors: KUAN-CHENG HUANG, YUNG-KAI CHEN

Patent number: 8270047Abstract: First, second, and third image planes are obtained from at least one image sensor. The first image plane is formed from light of a first spectral distribution. The second image plane is formed from light of a second spectral distribution. The third image plane is formed from light of a spectral distribution which substantially covers the visible spectrum. First spatial frequency components are generated from the first, second and third image planes. A second spatial frequency component is generated from the third image plane. A color transform is applied to the first spatial frequency components from the first, second, and third image planes to obtain at least first, second and third transformed first spatial frequency image planes. The at least first, second and third transformed first spatial frequency image planes are combined with the second spatial frequency component from the third image plane to form an image.Type: GrantFiled: June 26, 2008Date of Patent: September 18, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Stephen Pollard, Andrew Hunter, Renato Keshet

Patent number: 8269989Abstract: A printing data generating unit designates a first section (page numbers, etc.) corresponding to a change target part of a before-being-changed document and a second section corresponding to printing data of a changed part. A printing unit includes a replacement processing portion. The replacement processing portion determines whether or not the section of the counted number of sheets of paper matches the first section, and when they match, instructs the printing unit to print the printing data of the changed part corresponding to the second section, and when they do not match, causes the before-being-changed document to be discharged directly from the printing unit, and thereby replacing just the first section of the before-being-changed document with a document of the changed part corresponding to the second section.Type: GrantFiled: September 28, 2005Date of Patent: September 18, 2012Assignee: Sharp Kabushiki KaishaInventor: Atsushi Uemura

Patent number: 8264746Abstract: An image sensor includes: a light transmissive member extending in a direction orthogonal to a direction of conveying the document; a reference portion provided outside the conveying region where a document is conveyed with respect to the orthogonal direction and having a transmittance lower than a transmittance of in the conveying region of the light transmissive member; and a light source unit. The image sensor further includes: a lens unit converging the light transmitting through the document and the reference portion; a light receiving unit that receives the light transmitted through the lens unit and outputs an electric signal; an amplifying unit that amplifies the electric signal of the document corresponding to the conveying region and outputs an image signal of the document; and a controlling unit configured to control an amplification factor of the amplifying unit based on the electric signal corresponding to the reference portion.Type: GrantFiled: May 27, 2011Date of Patent: September 11, 2012Assignee: Mitsubishi Electric CorporationInventors: Naoyuki Tokida, Takafumi Endo

Patent number: RE43892Abstract: A four-line CCD sensor is structured by line sensors R, G, B in which color fillers are respectively disposed on surfaces of light receiving elements, and a line sensor BK at which no color filter is disposed. Amplitudes of signals which are outputted from the line sensors R, G, B at a time of reading a color document, and an amplitude of a signal which is outputted from the line sensor BK at a time of reading a monochrome document are adjusted so as to be substantially equal to one another. In a case in which a color document is read, outputs of the line sensors R, G, B are selectively provided, and in a case in which a monochrome document is read, output of the line sensor BK is selectively provided.Type: GrantFiled: August 18, 2011Date of Patent: January 1, 2013Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventors: Jun Sakakibara, Koji Tanimoto
