ABSTRACT:
An image obtains a desired impression by adjusting a color on the basis of a color adjustment parameter which responds to input image data. An image processing apparatus includes storage means which stores image data having different hues, and an input device inputs image data to be color adjusted. A color adjustment unit performs a color adjustment to at least one of hue, saturation and lightness of the image data to be color adjusted using a color adjustment parameter. The color adjustment parameter responds to each of the hue, saturation and lightness of the image data to be color adjusted on the basis of the stored image data. The stored image data is selected on the basis of the hue of the image data to be color adjusted.
