<P>PROBLEM TO BE SOLVED: To achieve preferable color reproduction in an output device corresponding to an extension color space by determining a regenerative color gamut in input image data, defining a color standard color gamut as an optimal input color space and further selecting a color conversion profile having an optimal saturation compressibility for the regenerative color gamut in the input image data in accordance with the regenerative color gamut in the input image data. <P>SOLUTION: An image processing apparatus comprises a means for analyzing a regenerative color gamut in input image data and selecting an optimal standard color space as an input color space, and a means for setting a ratio of suited color gamut information by comparing color gamut information having a plurality of predetermined ratios in the selected input color space with the regenerative color gamut in the input image data, and implements color conversion processing in the input image data and outputting an image using the standard color space defined as an input color space and a color conversion profile in an output device by selecting the color conversion profile resulting from optimizing a saturation/gradation compression parameter for an output color space for the ratio of suited color gamut information. <P>COPYRIGHT: (C)2007,JPO&INPIT |
