Publication number: 20040120517Abstract: To reduce processing load or processing time required for compression and encryption of data. Data to be compressed, such as image data, is divided into specified block sizes by am image divider (10). A quantizer (12) references a quantization table (14) to quantize each of these blocks of data. The result of this quantization is entropy encoded by an entropy encoder (16) referencing a coding table (18) to acquire compressed data. An encryptor (20) encrypts the quantization table (14) and coding table (18) used in the quantization and encoding using a specified encryption method. A multiplexor (24) gathers together the encrypted data acquired as a result together with the compressed data in a specified format.Type: ApplicationFiled: July 23, 2003Publication date: June 24, 2004Applicant: FUJI XEROX CO., LTD.Inventors: Kohshiro Inomata, Katsuya Mitsutake

Publication number: 20040122626Abstract: When a movement detector section detects that a network device has been moved, a deletion section causes the deletion of pre-movement positional information stored in a positional information storage section. When an alert output section detects a state in which no positional information is set in the positional information storage section, the alert output section outputs an alert. A positional information setter section updates the positional information storage section with post-movement positional information of the network device which is input by an administrator in response to the alert so that the actual installation position matches the positional information set in the positional information storage section. In this manner, the network device avoids a situation in which positional information indicating an installation position before movement is still set even after the device has been moved.Type: ApplicationFiled: November 12, 2003Publication date: June 24, 2004Applicant: FUJI XEROX CO., LTD.Inventors: Junichi Okuyama, Katsuya Mitsutake

Publication number: 20040119722Abstract: Methods and systems for classifying images, such as photographs, allow a user to incorporate subjective judgments regarding photograph qualities when making classification decisions. A slide-show interface allows a user to classify and advance photographs with a one-key action or a single interaction event. The interface presents related information relevant to a displayed photograph that is to be classified, such as contiguous photographs, similar photographs, and other versions of the same photograph. The methods and systems provide an overview interface which allows a user to review and refine classification decisions in the context of the original sequence of photographs.Type: ApplicationFiled: December 23, 2002Publication date: June 24, 2004Applicant: Fuji Xerox Co., Ltd.Inventors: David M.

Patent number: 6754453Abstract: The present invention relates to a method for applying usage or weighting factors to static cycle counts or “clicks” as tallied in a document processing system. The application of weighting factors to a system cycle count when suitably summed will provide superior measure of the wear to a replaceable element as well as improved indication for the determination of the end of life for a replaceable element in that system. As such the more timely service or substitution for that replaceable element in the system can be provided, thereby allowing costs and service down-time to be minimized.Type: GrantFiled: December 28, 2001Date of Patent: June 22, 2004Assignee: Xerox CorporationInventors: Robert P.

Patent number: 6753976Abstract: The present invention is directed to a method for differentially processing image types within a document image to enhance the quality of on an image on a receiving medium. In one aspect of the invention, the method begins by receiving document image data including one or more image regions. The method determines for each image region whether the region includes any image data corresponding to a first image type. The method then prints regions including image data corresponding to the first image type according to a first pixel management process and prints regions not including image data corresponding to the first image type according to a second pixel management process.Type: GrantFiled: December 3, 1999Date of Patent: June 22, 2004Assignee: Xerox CorporationInventors: Peter A. Torpey, Virgil Joseph Hull, Glenn K. Smith, Lesley P. Dudek

Patent number: 6752888Abstract: The present disclosure relates that constraining a substrate into a convex arc prior to mounting and affixing of any chips, allows those chips to achieve exemplary final chip-to-chip abutment when the substrate is released and allowed to return to stasis. This is particularly of use where there are any intervening thermal cycles, and the thermal temperature coefficients of expansion for the chip/die and any substrate/mount are significantly different. This will allow the utilization of otherwise more desirable materials for the substrate in spite of some mismatch in thermal coefficients that may exist between the substrate and chips.Type: GrantFiled: December 12, 2001Date of Patent: June 22, 2004Assignee: Xerox CorporationInventors: Paul A. Hosier, Kraig A. Quinn

Systems and methods to determine a contrast and a brightness adjusted system tone reproduction curve
Patent number: 6753987Abstract: Contrast and brightness adjustments can be made to a system tone reproduction curve. These contrast and brightness adjustments can be made, for example, by user, via a user input device, or alternatively, automatically detected, based on an image analysis routine. By determining one or more generic tone reproduction curves, and interpolating these tone reproduction curves with the system tone reproduction curve, a new, adjusted tone reproduction curve is produced. This allows for a determination of the adjusted system tone reproduction curve as opposed to calculating and restoring the families of system tone reproduction curves adjusted for all the possible combinations of contrast and brightness.Type: GrantFiled: February 25, 2000Date of Patent: June 22, 2004Assignee: Xerox CorporationInventors: Charles E.
