Abstract
A color adjustment, which matches a directional property STUV given by sensuous terms relating to color tones, can be performed by converting color image data into a color space having a direction of lightness M, a direction of saturation N and a hue axis K, and relatively changing a lightness component and a saturation component of the color image data in the color space.
Claims20
A color image processing apparatus for executing a color adjustment on color image data, comprising:
- an operation input means for giving an instruction on an increase or a decrease of a property expressed by a predetermined sensuous term relating to a color tone of the color image data;
- and
- a color adjusting means for changing the color image data in a direction of change corresponding to the predetermined sensuous term in a predetermined color space in response to the instruction on the increase or the decrease, thereby executing the color adjustment of the color image data,
- wherein the direction of change is a direction which relatively changes at least two components of a lightness component, a saturation component and a hue component of the color image data in the color space.
