The mail data is divided every predetermined reference data size into divided files which are sequentially transmitted as divided mails. When completion of transmission of divided mails corresponding to a unit image is confirmed, the image data and mail data of the unit image are eliminated from the work memory. By sequentially performing such a process, the memory use efficiency can be improved while holding image data of a unit image which has not been transmitted yet.Type: GrantFiled: March 26, 2002Date of Patent: February 10, 2009Assignee: Minolta Co., Ltd.Inventor: Atsushi Ishikawa

Patent number: 7471424Abstract: An original size detecting apparatus is capable of carrying out accurate original size detection without erroneous detection of the size of an original due to the influence of external scattered light. A CCD reads reflected light of light irradiated from a light source onto an original placed on an original platen glass. Optical sensors detect two open states of the original presser plate, and a scanner controller performs predetermined control corresponding to each of the open states of the original presser plate detected by the optical sensors, to determine the size of the original based on the result of the reading by the CCD.Type: GrantFiled: February 25, 2004Date of Patent: December 30, 2008Assignee: Canon Kabushiki KaishaInventors: Katsuhiro Ishido, Takashi Soya

Patent number: 7433098Abstract: A document processing system comprising an image capture subsystem for capturing selected image metrics and at least one image rendition from a plurality of documents and for determining if at least one of the selected image metrics for any of the at least one image rendition does not successfully compare against preselected image quality metric threshold values. An image quality flag is generated for any of the at least one image rendition if it does not successfully compare, and a record entry for each imaged document having at least one flagged image rendition is created in an image quality flag file. An image index file for individually accessing the image renditions is modified to include a reference to the corresponding image quality flag file record entry The document processing system may optionally compare selected document metrics against preselected document metrics in a similar manner.Type: GrantFiled: April 30, 2004Date of Patent: October 7, 2008Assignee: Unisys CorporationInventors: Robert D. Klein, Craig F. Lapan, George E. Reasoner, Jr.

Patent number: 7420717Abstract: A method and an apparatus for scanning an image. The method includes determining a first side of the periphery of an original document while moving an image sensor, detecting first and second reference points representing first and second end points of the first side, scanning an image between the first and second reference points, and determining a second side of the original document opposite to the first side, wherein the scanning is stopped.Type: GrantFiled: December 15, 2003Date of Patent: September 2, 2008Assignee: Samsung Electronics Co., Ltd.Inventor: Ji-sub Park

Patent number: 7391917Abstract: Stored digital data is searched for on the basis of an input image, difference information is extracted by comparing the retrieved digital data and the input image, and the difference information is composited to the digital data. Digital data generated by composition is stored. When no digital data is retrieved, the input image is converted into vector data, and the image that has been converted into the vector data is stored as digital data. Obtained region segmentation information and an input image are composited, the composite image is displayed on an operation screen of an MFP, and a rectangular block to be vectorized is designated as a specific region from the displayed region segmentation information. A user designates the specific region by designating rectangular blocks in an image using a pointing device.Type: GrantFiled: February 11, 2004Date of Patent: June 24, 2008Assignee: Canon Kabushiki KaishaInventors: Ken-ichi Ohta, Hiroshi Tanioka, Akihiro Usami, Kitahiro Kaneda, Hirohiko Ito, Shinichi Kato, Tomohiro Akiba, Tomotoshi Kanatsu, Reiji Misawa, Yoshihide Terao, Mitsuru Uzawa

Patent number: 7376258Abstract: An image quality assurance method for identifying image defects in a plurality of previously-imaged documents, where each previously-imaged document includes at least one image rendition stored in at least one image rendition file according to type of image rendition. The image renditions are analyzed to provide selected image metrics, the latter of which are compared against preselected image quality metric threshold values. An image quality flag is generated for any image rendition if at least one of the selected image metrics for that image rendition does not successfully compare against the preselected image quality metric threshold values. A record entry is created in an image quality flag file for those documents having at least one flagged image rendition, the record entry including information about the selected image metrics of the at least one flagged image rendition for that imaged document.Type: GrantFiled: April 30, 2004Date of Patent: May 20, 2008Assignee: Unisys CorporationInventors: Robert D. Klein, Craig F. Lapan, George E. Reasoner, Jr.

Publication number: 20080080016Abstract: An image forming system includes a first data compressing device, a data decompressing device, and an image forming device. The first data compressing device stores image data of a top line to be formed on a recording medium first and image data of a designated line other than the top line in a memory area with a data format capable of forming the original image data by itself, while generating difference data which indicates a difference between image data of a non-designated line other than the top and the designated lines and the image data of a line adjacent to the non-designated line, and stores the difference data in the memory area. The data decompressing device sequentially decompresses the image data of each line, based on the image data and the difference data. The image forming device forms an image on the recording medium, based on the decompressed image data.Type: ApplicationFiled: September 27, 2007Publication date: April 3, 2008Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Toshiki NARUKAWA
