Color image processing apparatus

A color image processing apparatus comprising:

• input means for inputting color image data representing a color image of interest;
• selection means for selecting one of plural mapping modes;
• and
• mapping means for color-gamut mapping the color image data based on the mapping mode selected by said selection means,
• wherein said plural mapping modes include:
• a first mode for reproducing the color image data within a color gamut of an output device so that the color image data has a high fidelity;
• a second mode for mapping color image data outside of the color gamut of the output device into the color gamut of the output device;
• and
• a third mode for mapping the color image data so as to enlarge a gamut of the color image of interest.

A color image processing apparatus comprising:

• input means for inputting color image data representing a color image of interest;
• memory means for storing color-gamut mapping data corresponding to a plurality of color gamuts;
• extraction means for extracting information on a color gamut of the color image of interest;
• setting means for automatically setting the color-gamut mapping data based on the information on the color gamut of the image data;
• and
• color-gamut mapping means for mapping the color image data based on the color-gamut mapping data set by said setting means.

A color processing method comprising:

• an input step of inputting color image data representing a color image interest;
• a selection step of selecting one of plural mapping modes;
• and
• a mapping step of mapping the color image data based on the mapping mode selected in said selection step,
• wherein said plural mapping modes include:
• a first mode for reproducing color image data with a high fidelity within a color gamut of an output device;
• a second mode for mapping color image data outside of the color gamut of the output device into the color gamut of the output device;
• and
• a third mode for mapping the color image data so as to enlarge a gamut of the color image of interest.
