    • A color conversion technique which places an importance on a color difference and converts an input color outside a gamut into a color inside the gamut to minimize the color difference is available. However, this technique does not determine whether the input color falls inside or outside a visual limit range. Upon processing image data between image input/output devices, image data is input (S201), it is determined whether the input image data falls outside a predetermined gamut (S204), and image data which is determined to fall outside the gamut is converted into a color on the inframarginal portion of or inside the gamut (S206).
    • 可以使用将色差重要性并将色域外的输入颜色转换为色域内的颜色以最小化色差的颜色转换技术。 然而,该技术不能确定输入颜色是否落在视觉限制范围之内或之外。 在图像输入/输出装置之间处理图像数据时,输入图像数据(S201),确定输入的图像数据是否落在预定的色域之外(S204),并且被确定为落在色域外的图像数据被转换成 在色域的超边缘部分或内部的颜色(S206)。

    • In a system for converting an input image signal input from an image input device into an output image signal to be output by an image output device, an image compression unit converts a spectral image input via an image input unit into R, G, and B data, obtains principal component data by making principal component analysis of the spectral image, and stores these data in an input image storage unit. When the principal component data and R, G, and B data are loaded and stored in an output image storage unit, a spectral reflectance reconstruction unit reconstructs the spectral reflectance of each pixel using these data. A printer model determines the dot quantities of inks used to record each pixel in an image output device on the basis of the calculated spectral reflectance, and generates an output image signal for the image output device. In this way, image data which allows to estimate the spectral reflectance characteristics of an input image is provided, and faithful color reproduction can be realized.
    • 在用于将从图像输入装置输入的输入图像信号转换成由图像输出装置输出的输出图像信号的系统中,图像压缩单元将经由图像输入单元输入的分光图像转换为R,G和B 数据,通过对光谱图像进行主成分分析来获得主成分数据,并将这些数据存储在输入图像存储单元中。 当主成分数据和R,G和B数据被加载并存储在输出图像存储单元中时,光谱反射率重建单元使用这些数据重建每个像素的光谱反射率。 打印机型号基于所计算的光谱反射率确定用于记录图像输出装置中的每个像素的墨水的点数,并且生成用于图像输出装置的输出图像信号。 以这种方式,提供允许估计输入图像的光谱反射特性的图像数据,并且可以实现忠实的色彩再现。

    • A primary color dot gain correction unit corrects the spectral reflectance of each of a plurality of color agents on the basis of the dot quantity set for each color agent. An initial estimated value calculator estimates a mixed color by the KM theory using spectral reflectance data corrected by the primary color dot gain correction unit. An ink overlap correction coefficient storage unit stores correction coefficients, which are determined on the basis of errors between the actually measured values of spectral reflectance data of color patches obtained using the plurality of color agents, and estimated values estimated by the initial estimated value calculator based on the dot quantities of the respective color agents on the color patches. An ink overlap correction unit obtains the prediction result of a reproduction color by correcting the spectral reflectance data of the mixed color calculated by the initial estimated value calculator on the basis of the correction coefficients stored in the ink overlap correction coefficient storage unit.
