ABSTRACT:
To approximate with precision the nonlinear output characteristic of an output device and enable high-precise color reproduction, a method is provided to convert a device-independent color space into an output device-dependent color space. A colorimetry value of a color patch output by the output device and represented in the device-independent color space is input, and a colorimetry value close to a conversion target value represented in the device-independent color space is extracted from the input colorimetry value. According to a distance between the input and extracted colorimetry values in the device-independent color space, there is performed a weighting process for a color value corresponding to the extracted colorimetry value and represented in the output device-dependent color space, to obtain a color value corresponding to the input colorimetry value and represented in the output device-dependent color space.
