Estimating the term…
From profiles of an input color space and an output color space, the specific color data on respective color spaces are obtained, and a color space compression parameter is set based on each specific color data obtained. In other words, the color space compression parameter for appropriately converting data within the input color space into data within the output color space is derived from each specific color data. The color space compression processing (color matching) is performed on an absolute color space using the derived color space compression parameter so that it becomes possible to perform at a higher speed an appropriate color matching that takes into account the characteristics of the input color space and the output color space.
A color matching method in which, when color reproduction ranges of a first device and a second device differ, image data within a color reproduction range of said first device is converted using a conversion parameter into image data within a color reproduction range of said second device, comprising the steps of:
A color matching device for converting image data within a color reproduction range of a first device into image data within a color reproduction range of a second device using a conversion parameter when the color reproduction ranges of said first device and said second device differ, comprising:
A computer readable record medium storing a color matching program for having a computer execute a color matching method for converting image data within a color reproduction range of a first device into image data within a color reproduction range of a second device using a conversion parameter when the color reproduction ranges of said first device and said second device differ, wherein said color matching method includes the steps of:
