  • Patent number: 7139513
    Abstract: A developing device unit has a developing device unit main body which rotates about a rotary shaft. Plural developing devices are disposed on the developing device unit main body. The developing devices respectively have developing device main bodies, and developing agent cartridges containing four color developing agents are respectively loaded into the developing device main bodies. The developing agent cartridges are attached/detached in a direction substantially tangential to the rotating direction of the developing device unit main body when a grip section is gripped and operated by the operator in the case where the developing agent cartridges are at a location substantially opposite an image carrier with respect to the rotary shaft.

  • Patent number: 7139024
    Abstract: An imager circuit includes an array of pixels, each pixel including a sensor (photodiode) connected to an input terminal of a comparator. The comparators of each pixel row have output terminals connected to a latch. A counter generates a sequence of digital values that are transmitted to a digital-to-analog converter (DAC) and to the latch of each row. The DAC generates a ramp voltage that is transmitted to a second input terminal of each pixel's comparator. The comparators of a selected pixel column are enabled to generate output signals when the ramp voltage equals each pixel's voltage, causing the associated latches to capture the current digital values. The comparators are formed such that each pixel row shares a cascode mirror circuit that detects differential currents in data line pairs connected to each pixel in that row.

  • Patent number: 7140007
    Abstract: Techniques that allow the operations of a program to be intercepted and intervened with are known. These techniques are restricted by the same limited view of the program's data that is currently available at a base level of an object or method. Some aspects need access to more information about the program's data of one or more objects than is available at the base level. An aspect of aspect-oriented programming systems, methods and environments examines the results of a computation at one stage. That aspect affects only subsequent stages of the computation, so that no circularity exists. Custom flow analyses, whether local or global, can also be performed at each stage to propagate non-local information. “Macro” style programming can be reduced or avoided, as programming can be facilitated in terms of manipulating the results of various computational stages instead of in terms of manipulating blocks of code.

  • Patent number: 7139099
    Abstract: Disclosed are an image processing device and an image processing method capable of generating a high-resolution color image of a fine gray scale from image data of a small information amount by using a small memory capacity. A character graphics image of high resolution generated by a character rasterizing block is converted by a conversion block to image data in which color information of one color is assigned per group of pixels, and tag information indicating whether the color information is used or not is added with respect to the multiple pixels to which the color information is assigned. By the tag information, while maintaining the high resolution, a fine gray scale can be assured. An image decoding block which has received such image data decodes the image data into a color image of output resolution by assigning the color information to the position indicated by the tag information.

  • Patent number: 7139442
    Abstract: A method and a system for separating an image signal into a set of image planes are disclosed. The system comprises a way to perform resolution conversion from low resolution to high resolution binary images either for synthetic or scanned imagery by using template matching with pattern replacement. More specifically, the invention applies resolution conversion to the selector plane of mixed raster content images. For selector planes in which edges are encoded (vs. region classification), template matching/pattern replacement works well, and does not affect halftoned regions, as they are not encoded in this image.

  • Publication number: 20060256385
    Abstract: An image processing method generates a halftone image by forming a halftone dot represented by a set of one or plural output dots corresponding to an intensity of an input image signal while making a part of the dots constituting the halftone dot to be an actual non-output dot so as to reduce an amount of a coloring material of a halftone-dot portion. The image processing method includes holding in a predetermined storage medium halftone-dot profile data for forming the halftone dot corresponding to the intensity of the image signal and gap-size profile data representing a size of a set of the non-output dot; and generating the halftone dot comprising a gap having a size based on the gap-size profile data, a size of the halftone dot being based on the halftone-dot profile data.

  • Publication number: 20060256394
    Abstract: For an automatic image diagnosis, toned images or residual toner existing on the photoconductive surface of a photoreceptor may be scanned with light energy provided by the raster scanning system. The light energy, which may be reflected from the photoreceptor surface, may be disturbed due to scattering/absorption in toned or damaged surface regions. The light energy may be directed to image sensors to obtain a spatial image map of the photoreceptor surface in conjunction with pixel clock information present for the raster scanning system. The evaluation may be made based on the spatial image map. Diagnostic and maintenance may then be applied to correct the defect and/or adjust a tone level for a latent image formed on the photoreceptor surface.

  • Publication number: 20060255526
    Abstract: A media separator, that cooperates with a media pick to form a nip in a feed path of a media handling apparatus, supports a separation pad that includes first and second friction regions for movement relative to the media separator, against a bias force, in a feed direction of a sheet of media through the nip. The first and second friction regions selectively engage the sheet of media passing through the nip with a retard/separation force determined by the bias force, to retard and control a feeding operation of the sheet of media through the nip, and to feed plural sheets of media through the nip one at a time.

  • Publication number: 20060257158
    Abstract: A capability is provided to reduce misregistration effects, and/or color-to-color registration errors, in output multi-color images based on velocity and position deviations and/or disturbances in transfer subsystems in image forming devices. A capability is provided to automatically compensate for torque disturbances caused by a photoreceptor belt seam crossing a mechanical device in a photoreceptor belt-based transfer subsystem in an image forming device. A learning algorithm, based on a mathematical model of transfer subsystem mechanical operational dynamics by which a series of performance curves could be generated, is employed to facilitate prediction of a torque disturbance profile in a mechanical motor driven transfer subsystem in an image forming device in order to produce a response profile which automatically predictively attempts to nullify the effects of the mechanical torque disturbance.
