Patent number: 6122078Abstract: A system for scanning and digitizing large images using a reseau for accuracy without obscuring the image to be scanned. The system uses two separate CCD photoreceptor arrays which are fixed in a rigid position with respect to each other and any accompany lenses and mirrors. In one embodiment, a first CCD photoreceptor array is used to scan the image while the second CCD photoreceptor array simultaneously scans the reseau. In a second embodiment, a single CCD photoreceptor array is used to first scan the reseau and then to scan the image. One illumination source illuminates the reseau while second illumination source illuminates the image. The arrangement of the lens(es) and the photoreceptor arrays allows the determination of any displacement of the scanner along the X-axis, Y-axis, and Z-axis, as well as the determination of any rotation of the scanner around the X-axis, Y-axis, or Z-axis.Type: GrantFiled: August 24, 1995Date of Patent: September 19, 2000Assignee: Vexcel Imaging GmbHInventors: Franz W. Leberl, Christian Jorde, Michael Gruber

Patent number: 6023348Abstract: A dual drum rotary image scanner has a headstock and a tailstock between which may be mounted drums of different diameter. The tailstock has substantially annular surfaces which contact corresponding surfaces on the different diameter drums. The different drums, when held in the scanner, each create a different separation between the headstock and tailstock. These different separations are detected by photodetectors, the outputs of which are received by a system controller. The controller uses the photodetector signals to control motors that position the scanning head and the transmittance illuminator relative to the surface of the particular drum mounted in the scanner. The motors turn pinions which, in turn, move racks to which are attached the scanning head and the transmittance illuminator, respectively. The movement of the scanning head also results in the modification of the optical path within the optics box of the scanner.Type: GrantFiled: October 18, 1994Date of Patent: February 8, 2000Assignee: Howtek, Inc.Inventors: Thomas W. Bosse, Mark W. Magee, Richard F. Lehman, Calvin Winey, III

Patent number: 5896203Abstract: In a facsimile apparatus, transmission image data is stored in an image memory after being produced by encoding and compressing raw image data. A storing operation of the transmission image data and a transmitting operation for transmitting the transmission image data are performed at the same time. A receiving operation is prohibited when the transmitting operation is being performed and the transmitting operation is prohibited when the receiving operation is being performed. Thus, the transmitting operation and the receiving operation are not interrupted due to an insufficient memory capacity of the image memory. Additionally, the transmission image data is transmitted by each set of block data when the operation of the image information communication apparatus is switched to the G3 facsimile communication mode. The transmission image data is transmitted by each set of single-page image data when the operation is switched to the G4 facsimile communication mode.Type: GrantFiled: April 3, 1996Date of Patent: April 20, 1999Assignee: Ricoh Company, Ltd.Inventor: Hiroshi Shibata

Patent number: 5880856Abstract: Disclosed herein is a method of storing and of progressively transferring a still image so that it can be conveniently previewed during the transfer and so that a user can terminate the transfer at an early stage if the image turns out to be undesirable. The methods of the invention include transforming the image into a plurality of decomposition levels using a discrete wavelet transform. Each decomposition level comprises a plurality of subimages which allow reconstruction of an image representation of the still image. The decomposition levels are transmitted beginning with a base decomposition level providing a low level of image resolution and then proceeding with decomposition levels providing increasingly higher levels of image resolution. Within each decomposition level, rows of the various subimages are arranged or interlaced together in contiguous blocks, so that all data for a single row, at a single decomposition level, is transmitted together.Type: GrantFiled: November 19, 1996Date of Patent: March 9, 1999Assignee: Microsoft CorporationInventor: Philippe Ferriere

Patent number: 5861960Abstract: An image signal encoding apparatus reads an image from an original and converts the image into color data values including lightness and chromaticity components. The data values are stored and divided into pixel blocks with data values of lightness components and pixel blocks with data values of chromaticity components. Average lightness component data values are computed for pixel blocks of lightness components and average chromaticity data values are computed for pixel blocks of chromaticity components. A region determination is made whether the pixel blocks correspond to a color, monochrome or background region in the original based on the average pixel block data values of lightness components and chromaticity components. A switch outputs the lightness pixel block data values during the region determination, and outputs the lightness and chromaticity pixel block data values after the region determination.Type: GrantFiled: September 20, 1994Date of Patent: January 19, 1999Assignee: Fuji Xerox Co., Ltd.Inventors: Kazuhiro Suzuki, Toshiaki Yoshinari, Taro Yokose, Ken Umezawa

Patent number: 5838458Abstract: A method and apparatus for receiving document images including portions linked to one or more electronic addresses. The linked portion of the document is identified using a predetermined visual attribute, such as bold-face text, or delimiters to mark the portion. The document image is then transmitted using, e.g., existing apparatus for transmitting images, such as a facsimile machine. An electronic address associated with the identified portion of the document is also transmitted using existing techniques, such as by touch-tone telephone. The address may be a voice telephone number, facsimile telephone number, World Wide Web address, or any other address with which communication can be established. At the receiving end, both the document image and electronic address are received. Pattern matching is performed on the document image to identify the portion with the predetermined attribute as a linked portion. The received electronic address is then correlated with the linked portion.Type: GrantFiled: December 14, 1995Date of Patent: November 17, 1998Inventor: Irving Tsai

Patent number: 5835688Abstract: A system is provided for automatically analyzing timing constraints of capabilities, and establishing parameters for automatic generation of finite-state machines which schedule from print engine capabilities. The system generates a finite-state machine which encodes, for each capability, a means by which any given schedule may be extended to one that includes a correct or optimal schedule for that particular capability. The system generates finite-state machines for both forward and backwards scheduling. It is adapted for both greedy and optimal search strategies. The system facilitates selectively leaving classes of constraints for run-time checking in order to reduce a size of a finite-state machine. Finite machines so generated are suitably used with schedulers to alternately control operation of a print engine.Type: GrantFiled: June 7, 1995Date of Patent: November 10, 1998Assignee: Xerox CorporationInventor: Markus P. J. Fromherz

Patent number: 5828468Abstract: A fax network for communicating fax transmissions over either a conventional public switched telephone network or a digital (frame relay) network based on a telephone number of a destination fax machine. If the destination fax machine can be serviced by the digital network, a faxjack intercepts the phone digits on the telephone link, and redirects the call to a local point-of-presence, which is preferably located near the local exchange carrier. The POP receives information related to the desired fax transmission from the faxjack, and accesses a destination POP via the digital network. The destination POP is local with respect to the destination fax machine, and the destination POP attempts to contact the destination fax machine to ascertain if a fax session is allowable. If so, the destination POP notifies the source POP, which then notifies the faxjack, thereby allowing the fax session to start.Type: GrantFiled: May 17, 1996Date of Patent: October 27, 1998Assignee: NKO, Inc.Inventors: Warren S. Lee, David W. Copp, Dale T. Platteter, Neil P. Carrier
