<p>A method and apparatus for reducing the occurrence of a problem which a first conversion method has for colors in the neighborhood of a color gamut when colors are converted, and a problem which a second method has in the conversion of a color far from the color gamut. When an L*a*b* value of a certain color is outside a target color gamut to be converted, it is judged (S2) whether the L*a*b* value is located within the range of the color gamut set under a predetermined condition. This set range is a range in which the accuracy is degraded if colors are converted using only the first method, for example, a range in the neighborhood of the color gamut. If a color to be converted is located within the range, colors are converted using the second method (S3). If the L*a*b* value of the color to be converted is outside of the set range, it is converted using the first method (S5) until the conversion result is contained within the range. <IMAGE></p> |
