The output specification information specifies, for example, the address of a printing device used as an output resource, the type of printing paper used for printing, and the number of copies. The image file is transmitted to an image processing system on a network.

Abstract: The image processing device of the present invention maps signal values on saturation segments to corresponding signals on an achromatic axis. In conjunction with this, mapping of color signal present around the saturation segments is mapped while preserving the continuity prior to mapping. The image processing device determines the displacement level entailed in mapping color signal surround a saturation segment so as to be inversely proportional to distance from the saturation segments. Since chroma of signals on the saturation segments change precipitously before and after mapping, by mapping signal surround the saturation segments so as to preserve the continuity of the original signals of signals surround the saturation segments, chroma gradation of signals on the saturation segments and signals around saturation segments can be preserved with a high degree of accuracy.

Abstract: In an image processing apparatus, a desired image processing is applied to an input signal by using a color correction table which changes an amount of conversion for a white point according to the luminance of white provided from an image output apparatus. It is possible to avoid influence of adaptation of the eye by making chromaticity of a target white point (D=O, (xwt, ywt)) close to chromaticity of white of the image output apparatus (D=1, (xwd, ywd)). Further, the target white point after the conversion is made close to a white point of the image output apparatus as luminance of the white provided from the image output apparatus increases. The reason for this constitution is that the human eye tends to adapt to bright light more than to dark light.

Abstract: To provide a method for generating color-correction lookup table for better using a color reproduction area of an output system, an image processing apparatus, an image processing method, and a recording medium. An image processing apparatus uses a color-correction lookup table to apply a desired color correction to an input image signal. The image processing apparatus is provided with a color-correction lookup table for chroma enhancement, which applies chroma-enhancement processing to a desired color point in the input image signal in an area where an output system gamut is wider than an input system gamut, and uses the color-correction lookup table for chroma enhancement according to the input image signal for performing the desired color correction. The color-correction lookup table for chroma enhancement does not perform the chroma-enhancement processing when the desired color point is close to achromatic color.
