PROBLEM TO BE SOLVED: To visually adjust color space value correspondence relation and to simplify the adjustment. SOLUTION: A device for adjusting color space value correspondence relation displays the color gamut of a color conversion table to be an adjustment object and a target color gamut on a display. A user can adjust the color conversion table to be the adjustment object so that the conversion table matches a target on a display screen. To put it concretely, a point (corresponding to an L*a*b* value) to be the adjustment object can be dragged and dropped with a mouse to bring the point to the position of a target point. The device for adjusting the color space value correspondence relation calculates a CMYK value corresponding to the L*a*b* value at the position after movement, changes the L*a*b* value at the position before the movement and the CMYK value corresponding to it to the L*a*b* value at the position after the movement and the CMYK value corresponding to it and holds them. Also, when a certain point A is moved, the other point B is automatically moved as well in proportion to closeness to the moved point A. |
