  • Patent number: 8390883
    Abstract: An image processing apparatus that comprises an obtaining section that obtains data of numerical values or numerical expressions used to describe a drawing process, and a generating section that generates, based on data obtained by the obtaining section, image information including color information on a color of each of a plurality of pixels, the image information having a first set of color information that describes using a color space different from a color space defined by colors of colorants used by an image forming section, and a second set of color information that specifies an amount of black colorant used by the image forming section.

  • Patent number: 8264735
    Abstract: An image processing apparatus, which includes: an extraction section that extracts a drawing element to be printed in a black color; a contour portion determination section that determines a contour portion of the drawing element extracted by the extraction section; and a controller that controls a printing unit such that, for a portion determined as the contour portion by the contour portion determination section, the portion is overprinted on a printed background image, and for a portion not determined as the contour portion by the contour portion determination section, the portion is printed without printing the background image.

  • Patent number: 7362467
    Abstract: The image processing device and method of the present invention prevent a problem such as misregistration and a phenomenon that an edge pales, and enable high speed output in a color printer and a color copying machine. The color materials of Y, M, C of a predetermined amount are output onto a black object regardless of peripheral pixel values and thereby a phenomenon that an edge pales is prevented. In the edge of the black object, trapping processing according to peripheral pixel values is executed and a problem due to misregistration is made inconspicuous.

  • Patent number: 6867872
    Abstract: The present invention provides an image processing apparatus and an image processing method that enable efficient use of code information storage areas and can rapidly process code information to render characters. A character data management unit stores reference information for referencing the shape data of a character indicated by inputted character data in an intermediate code buffer in association with an intermediate code. Thereby, a data amount of the intermediate code buffer is reduced. At the same time, reference information for referencing the intermediate code is stored in a font cache buffer in association with the character shape data. By dint of the mutual reference, when character shape data is to be saved from, e.g.

  • Patent number: 6297829
    Abstract: To secure high quality, require no bulk memory and reduce processing time when code image data is expanded to plotted pattern data, a binary expansion section for expanding code image data to binary plotted pattern data, a multivalued expansion section for expanding code image data to multivalued plotted pattern data and an expansion method determining section for judging whether code image data is data for plotting a character and a line or not and whether code image data meets a predetermined condition or not and determining the expansion section to be applied are provided, and code image data is applied to the expansion section determined by the expansion method determining section.
