On that basis, from an example of color adjustment parameters set in directions of colors, it is found out that, when inputted V is in a negative range, B has a small influence. Accordingly, a B component is omitted from calculation in order to reduce a calculation amount. Similarly, components having small influences are omitted when B is in a positive range, when U is in the positive range, and when U is in the negative range. Thereby, adjustment parameters AR, AG, and AB set in directions shown in the drawing can be defined. When inputted V is in the positive range, a V component can be adjusted by multiplying AR by the inputted V. Similar processing is performed when inputted V is in the negative range, when U is in the positive range, and when U is the negative range, respectively.

Abstract: Conversion of colors of an image from a source color space to a destination color space by use of both a color profile and an image profile. The source and destination color spaces are respectively represented by source and destination color space transformations associated with source and destination color profiles. Colors in an image are converted from the source color space to a device-independent color space, using the source color space transformation.

The gamut mapping is applied, and the gamut mapped colors are transformed from the device-independent color space to the destination color space, using the destination color space transformation.
