  • Patent number: 6842788
    Abstract: A router can consider two color vectors for a path including multiple links through a network. One color vector indicates colors that all of the multiple links include. Another color vector indicates the colors that none of the multiple links include. In setting up a constraint-based label switched path (LSP), a router can use a program that includes a logical process. With the process, the router can automatically compute the color vectors for the path whenever the path of an LSP changes and/or the characteristics (colors) of one or more of the multiple links constituting the LSP changes. Computing whether the path is eligible for inclusion in the LSP includes calculating whether the path includes all colors that must be included in an LSP and calculating whether the path includes any of the colors that must be excluded from the LSP.

  • Patent number: 6804033
    Abstract: Upon executing auto color select (ACS) generally, since a prescan for ACS must be done before a main scan for capturing actual image data, a long processing time is required, resulting in low productivity. In this invention, an ACS task is executed while the scanner is making an image capture scan. If the ACS task determines that the captured original is a color original, the ACS task informs the printer of that information, and then normally terminates itself. After the end of scan, if it is not determined that the original is a color original, information indicating that the original is a monochrome original is sent to the printer. Hence, appropriate ACS can be done without any prescan.

    Abstract: When an L*a*b* value of a certain color is outside a target color gamut to be converted, it is judged whether the L*a*b* value is located within the range of the color gamut set under a predetermined condition. This set range is a range in which the accuracy is degraded if colors are converted using only a first method, for example, a range in the neighborhood of the color gamut. If a color to be converted is located within the range, colors are converted using a second method. If the L*a*b* value of the color to be converted is outside of the set range, it is converted using the first method until the conversion result is contained within the range. Then, the occurrence of both a problem which the first conversion method has for colors in the neighborhood of the color gamut when colors are converted and a problem which the second method has in the conversion of a color far from the color gamut can be suppressed.

  • Patent number: 6567186
    Abstract: The method of the invention converts colors resident in a first device color space to gray levels for reproduction in a color or monochrome rendering device. The method initially converts the color values resident in the first device color space to corresponding color values in a device independent color space. Next, the resulting color values in the device independent color space are converted to further color values in the same color space that correspond to color values resident in the color space of a target color rendering device. The further color values from the device independent color space are then converted to corresponding gray levels so that they may be rendered by either the target color rendering device or a different color or monochrome rendering device. The use of an intermediate gamut conversion within the device independent color space enables more precise gray representations to be achieved for certain color representations.

  • Patent number: 6559975
    Abstract: A method for transforming an image, containing an arbitrary number of colors from a full color process printing mode to a spot color printing mode while preserving the user's intended color usage as much as possible. The method is contained in a utility and referred to as “Spot Color Transformation” (SCT). The SCT utility provides a user the ability to transform an image generated by a computer program module, such as a desktop publishing computer program module, from a full color mode into a spot color mode. The SCT utility operates on an object-by-object basis to map objects within an image to one of several partitions: a black partition and a color partition. The SCT utility maps each object that has an associated color that is substantially black or a tint of black to the black partition. Next, the SCT utility converts the colors of unmapped objects to a tint of the spot color based on the luminance value of the particular color relative to the lowest luminance value found in the image.

  • Patent number: 6556312
    Abstract: Due to high resolution of color printers and the increased number of colors in image formation from four colors (Y, M, C and K) to six or seven colors including pale colors, the number of times of referring to LUT data and the number of times of calculation are increasing in interpolation operation for generating print data. In view of this, when inputted R, G and B data are converted to Y, M, C and K data by performing interpolation operation using a conversion table which expresses the input-output relations, if output values corresponding to eight vertices of a unit cube used for interpolation are the same value, the calculation is not performed but the value is outputted as the interpolation result.

  • Patent number: 6505252
    Abstract: In an image data server 200, a preview data generation unit 218 generates preview data corresponding to image data, and a transmission controller 211 transmits the preview data to a computer system 100 in an image receiver apparatus. In accordance with another possible application, the preview data is not generated by the image data server 200, but is generated by a computer system 300 in an image transmitter apparatus, which transmits the image data to the image data server 200, and transmitted to the image data server 200. In the computer system 100 in the image receiver apparatus, a display controller 113 causes the contents of the preview data to be displayed on the screen of a monitor 150. The user determines whether or not the image data corresponding to the displayed preview image is required. In response to an instruction for transfer of the image data input from the user, a transmission controller 111 transmits a request for transfer of the image data to the image data server 200.

  • Patent number: 6504950
    Abstract: An apparatus for creating an ICC profile in a simple manner without using a specialized measuring instrument. A display control unit reads out a dot pattern image from a pattern image data holding unit and a grayscale pattern image containing a plurality of grayscale patches of gradually varying gray scale from a grayscale image data holding unit, and presents the thus readout images for display on a display device. A user selects the grayscale patch having brightness closest to the brightness of the dot pattern image by operating a selection unit. Based on the selection, a gamma coefficient value is calculated by a gamma coefficient value calculation unit, and based on this gamma coefficient value, a profile creation unit modifies the ICC profile held in a common information holding unit and thus creates a customized ICC profile.

  • Patent number: 6486981
    Abstract: A color image processing apparatus which codes image data while suppressing image deterioration. A color character area discrimination unit divides an input color image into 16×16-pixel blocks, and determines whether or not each block expresses color characters. In accordance with the determination result, a sub-sampling ratio switching unit switches the sampling ratio for each of color components YCrCb composing the color image data so that the sample ratio is Y:Cr:Cb=4:2:2 or Y:Cr:Cb=4:1:1. Subsequently, sampling is performed in accordance with the switched sampling ratio, and DCT, linear quantization and entropy coding are then performed.
