Patent number: 7277201Abstract: Historically, the creation of digital line screens was considered to be a subset of the creation of the digital cluster dot screens. The geometric constraints necessary for digital cluster dot screens were imported into the creation of digital line screens. Accordingly, the number of available angles or digital line screens was also significantly limited. In various exemplary embodiments of the systems and methods according to this invention, a digital line screen cell is defined such that the vectors defining the digital line screen cell are not necessarily isometric and are not necessarily at right angles to each other. By using a high-addressability grid that has different resolutions along x and y axis of the grid, the systems and methods according to this invention allow the components of the vectors along the high-addressability direction to be noninteger multiples of the components of the vectors along the other direction of the grid.Type: GrantFiled: May 28, 2003Date of Patent: October 2, 2007Assignee: Xerox CorporationInventor: Charles M.

Patent number: 7277203Abstract: A method for initializing a printing system using error diffusion is discussed. In application of the invention to color printing systems, the method initializes a first error buffer with a first set of seed values and then initializes at least one other error buffer with another set of seed values. The other set of seed values is negatively correlated with respect to the first set of seed values in the first error buffer. The method then uses the seed values in all the error buffers to start an error diffusion process. For monochrome systems, only one error buffer is initialized with random numbers.Type: GrantFiled: September 21, 2000Date of Patent: October 2, 2007Assignee: Sharp Laboratories of America, Inc.Inventor: John Charles Dalrymple

Patent number: 7277204Abstract: A method of building threshold matrices for stochastic screening by using the actual size and shape of imaged pixel and/or pixel agglomerate instead of the nominal one, in the stage of calculating appropriate threshold matrices. For each relevant combination of imager and imaged media, a matrix with desirable blue-noise-like characteristics is created from actual imaged pixels and/or pixel agglomerates, taking into account their overlap when placed in close proximity.Type: GrantFiled: July 31, 2003Date of Patent: October 2, 2007Assignee: Kodak IL Ltd.Inventors: Alexander Krol, Alex Weiss

Patent number: 7277205Abstract: While a general large layer dither volume provides great flexibility in dither cell design, by decoupling different intensity levels, they are inefficient to access since each colour component requires the retrieval of a different bit from the volume. Therefore in a multi threshold dither volume for digital halftoning a contone colour image, in the form of an array of contone colour pixel values to bi-level dots, there is allocated for each dither cell location a fix set of n thresholds defining n+1 intensity intervals within which said dither cell location is defined to be alternatively not set and set.Type: GrantFiled: August 8, 2003Date of Patent: October 2, 2007Assignee: Silverbrook Research Pty LtdInventors: Paul Lapstun, Simon Robert Walmsley, Kia Silverbrook

Patent number: 7277206Abstract: A method for reducing image noise in a digital image including establishing image data of image pixel values; specifying a local virtual surface patch; fitting the local virtual surface patch to the image data; using the local virtual surface patch to estimate a palliative value of at least one pixel in the region of the local virtual surface patch; replacing an original pixel value with the palliative value.Type: GrantFiled: July 29, 2005Date of Patent: October 2, 2007Assignee: Corel CorporationInventors: Mikhail Ivanovich Trifonov, Kryzstof Antoni Zaklika, Pavel Vladimirovich Gruzdev

Patent number: 7277207Abstract: A recording device includes an image retrieval unit, a memory, an image forming unit, and a control unit. The image retrieval unit retrieves images of the document pages as document image data. The control unit begins retrieving document image data from the memory as the image retrieval unit is retrieving document image data and sends the document image data to the image forming unit. The image forming unit uses document image data to form images on recording sheets faster than the image data is retrieved. The control unit checks the memory to confirm whether document image data for a next document page is stored in the memory. The timing of the memory check is both after completion of forming an image of a present document page at the recording sheet transport speed and when storage of image data for the next document page is anticipated to start in the memory.Type: GrantFiled: July 23, 2002Date of Patent: October 2, 2007Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoshinari Okamoto, Makoto Suzuki

Patent number: 7277208Abstract: A hologram recording medium is provided which can prevent sensitization of a region thereof other than a data recording region thereby to prevent deterioration of a characteristic of the hologram recording medium. The hologram recording medium includes partition members for partitioning a recording material. Upon recording, unnecessary light generated when signal light and reference light enter the recording material is blocked from propagating in the recording material by the partition members and cannot advance into adjacent partitions. Therefore, unnecessary sensitization of the recording material by the unnecessary light can be prevented, and particularly, decrease of the recording capacity can be prevented. Consequently, the performance of a hologram recording and reproduction apparatus which adopts, for example, a multiplex recording system can be exhibited fully.Type: GrantFiled: March 25, 2005Date of Patent: October 2, 2007Assignee: Sony CorporationInventors: Nobuhiro Kihara, Hisayuki Yamatsu

Patent number: 7277209Abstract: The method consists of computing (E1-E4) a set of two-dimensional images in a three-dimensional geometrical space representing a virtual object from respective different viewpoints. The virtual object is represented by digital data stored in a computer. Holograms are computed (E5-E6) for the respective two-dimensional images using a fast complex transform, such as a Fourier transform. The holograms are then juxtaposed (E7) to form a digital hologram of the object which is physically reproduced (E8) by a spatial light modulator. A three-dimensional image of the object is obtained by illuminating the spatial light modulator with a coherent source.Type: GrantFiled: November 17, 1998Date of Patent: October 2, 2007Assignee: European Community (EC)Inventors: Jean-Claude Grossetie, Pierre Noirard

Patent number: 7277210Abstract: An optical apparatus in which multiplexed holograms are used to achieve wavelength selectivity and polarization manipulation is used to facilitate near-normal incidence of light on the holograms. The polarization manipulation allows light reflected from the holograms to be separated from the light incident on the holograms. In one application, the apparatus can be used to extract spectral lines of an analyte from radiation scattered from a sample.Type: GrantFiled: July 21, 2005Date of Patent: October 2, 2007Assignee: C8 Medisensors Inc.Inventor: Jan Lipson
