    摘要: The present invention generally relates to processing of color images and more particularly to a method for smoothing a color boundary between an object and a background. A method for changing the color of an object against the color of a background to smooth the color boundary between the object and the background includes the steps of: identifying the color of the boundary part of the object as a boundary color; obtaining a mixing ratio for mixing the color of the object and the color of the background to produce the boundary color; changing the color of the object relative to the color of the background; and changing the boundary color while maintaining the mixing ratio substantially constant at the boundary part before and after the color change process.

    摘要: 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.

    摘要: 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.

    摘要: In measuring a spectral irradiance distribution of light, light is irradiated to n (natural number) light-transit sections, which respectively have n kinds of given optical characteristic coefficients, and s (natural number) optical sensors, which respectively have s kinds of given spectral sensitivities, receive the light via the n light-transit sections and detects individual responses for the received light. Then a calculating section calculates m (natural number) spectral irradiances for m kinds of wavelengths as a spectral irradiance distribution based on linear formulae established between the optical characteristic coefficients, the spectral sensitivities, (n×s) responses for the light obtained by the s optical sensors, and the spectral irradiance distribution of the light.

    摘要: Color data for a color image device having a first color range (gamut) are converted into color data for a color image device having a second color range (gamut). For preventing colors from being altered when color data are converted, first color data in the first color range (gamut) of the first image device is converted into corresponding colors by referring to a classification table representing the correspondence between colors determined based on human color perception and the first color data, and then the first color data is converted into second color data in the second color range (gamut) of the second image device with respect to each of the classified colors. Since each of the colors based on the human color perception is converted, colors are prevented from being altered due to the conversion. Because each of the colors of a color image is converted, the clearness of the color image will not be lost.
