摘要： Image characteristics of a finally generated printed image that is reproduced from YMCK halftone dot percentage data from an image editor by an image output unit B are simulated highly accurately taking into account periodic noise and random noise, and the simulated image is outputted from an image output unit A. Specifically, the YMCK halftone dot percentage data from the image editor are converted into color image data corresponding to image characteristics of the image output unit B by an LUT combiner/converter, and periodic noise and random noise that can be produced by the image output unit B are applied to the color image data. The noise-applied color image data are then outputted from the image output unit A.

摘要： To deeply encrypt and embed auxiliary information into image data, table generation means generates a table, based on a quantization error which occurs when image data S0 is converted from a first color space, to which the image data S0 belongs, to a second color space that is a destination of conversion. The table represents which color coordinate of a second color space a color coordinate of a first color space is mapped onto. In coding means, information H0 to be embedded is coded by referring to the table, whereby coded auxiliary information H1 is obtained. When the image data S0 is converted in color conversion means, the auxiliary information H1 is embedded into the quantization error, whereby image data S1 embedded with the auxiliary information H1 is obtained.

摘要： Color patches established at given intervals are calorimetrically measured to determine a relationship between color signals Y, M, C, a lightness index L*, and chromaticnesses a*, b*. The determined relationship is processed by a dual regression analysis to determine color signals to be interpolated with priority in the order in which changes in the indexes are progressively greater as a color signal changes. The color signals are then interpolated with priority in the above order, and a highly accurate color conversion table is generated.

摘要： The improved color reproduction data conversion method of the present invention comprises the steps of obtaining the color matching ink amounts of CMY colors being metamer with the calorimetric data as to a plurality of different amounts of K-plate; obtaining an achromatic amount from a total ink amount of CMYK for each amount of the K plate; obtaining an achromatic amount function for the amount of the K plate in the linear portion; generating a mapping function from the calorimetric data and the achromatic amount to the ink amounts of CMYK in the linear portion and obtaining a weighting coefficient for reflecting to the achromatic amount with the K plate control condition previously selected; determining the achromatic amount from the colorimetric data; and calculating ink amounts of CMYK from the achromatic amount and the calorimetric data with the use of the mapping function of the CMYK ink amount. As a result, the invention method can obtain reproducible four-dimensional color reproduction data for actual printing from the three-dimensional colorimetric data while maintaining metamerism under a K plate generating condition set up arbitrarily by the user.

摘要： First colorimetric data with respect to device data C, M, Y with device data K=0 % are determined as a first color-predicting LUT, and second colorimetric data with respect to rough device data C, M, Y, K are determined as second color-predicting LUT. Third calorimetric data with respect to device data C, M, Y, K having the same device data K are predicted from the second colorimetric data. A third color-predicting LUT representing a relationship of the third colorimetric data to the device data C, M, Y, K is determined from the third calorimetric data. The first, second, and third color-predicting LUTs are established as a desired color-predicting conversion relationship.

摘要： YMCK halftone dot percentage data from an image editor are converted into color image data in an XYZ colorimetric system with a common color space conversion table generated by a common color space conversion table generator. The color image data are converted into a gamut mapping and appearance corresponding to an image monitor device with a gamut mapping/appearance table generated by a gamut mapping/appearance generator. Then, the color image data are converted into color image data in a device color space of an image output unit with a device color space conversion table generated by a device color space conversion table generator for thereby predicting a color image which will be reproduced by the image output unit. Alternatively, the YMCK halftone dot percentage data from the image editor may be corrected using dot gain correcting coefficients established respectively for tristimulus values X, Y, Z, and then converted into color image data in the XYZ color space with a common color space conversion table.
