Document Type and Number:
Japanese Patent JP2769498
Kind Code:
B2
Abstract:
A method for generating the characteristics of a set of colors in accordance with the present invention comprises the steps of selecting at least two, and typically more reference colors; describing each of the selected reference colors by a set of color characteristic data indicating the reflectance of each color at each of a set of predetermined wavelengths; and generating descriptions of the intermediate color samples by computing the relative proportions of each base color which characterizes each intermediate color and calculating a reflectance value at each wavelength for the color to be generated proportionate to the reflectance values for each base color at the corresponding wavelength. Also described is a set of color samples created as a result of the method for generating the characteristics of the colors and arranged in a geometry indicative of the method. A system for generating the color sample data in accordance with the present invention is described which comprises storage means for storing the photometric characteristics and other data; a central processing means under software control for accessing the stored data, computing the relative proportion of each reference color comprising each color to be generated, and computing the reflectances at each wavelength for which color reflectance data is stored for each intermediate color; and output means for outputting the data generated by the central processing means.
