摘要： A method of producing a color conversion table capable of enhancing continuity in an image-data color conversion, an image processing device and a method using the color conversion table, a program and a recording medium.

摘要： A method which enables high-accuracy color conversion. On condition that conversion from a second color space into a first color space can be made accurately, target coordinates in the first color space are determined and coordinates in the second color space are arbitrarily determined. The coordinates in the second color space are converted into coordinates in the first color space and the difference between the resulting coordinates and the target coordinates is calculated. A trial for moving the coordinates in the second color space is repeated until the difference becomes smaller than a prescribed threshold. Therefore, the correlation between the first and second color spaces can be defined by repeating only the accurate conversion process so that color conversion can be accurately made over the whole color gamut according to the correlation thus defined.
