摘要： PROBLEM TO BE SOLVED: To provide a LUT (lookup table) that contributes to the improvement of color reproductivity. SOLUTION: When creating a LUT 62 in which a correspondence relation between image data ORG (input value) of an RGB system and an output value of a YMC system, a hue transition track of the saturated color (YMC) of the YMC system is caught by functions (1) to (3) whose saturations are variable, and the functions are used to adapt a hue transition track about a color (correspondence color of the saturated color) of the RGB system corresponding to the saturated color. Even about a neutral correspondence color of the RGB system corresponding to a neutral color surrounded by the functions (1) to (3) in each of the saturated colors, a hue transition track is determined by the functions (1) to (3) of the saturated colors of both sides of the neutral color and functions (4) to (6) using a color deviation between the saturated colors of both sides of the neutral color and the neutral correspondence color, and by the hue transition track, a hue transition track is adapted even about a neutral correspondence color of the RGB system.

摘要： PROBLEM TO BE SOLVED: To provide an LUT (lookup table) by which various sorts of images can be suitably printed. SOLUTION: New one LUT is created by preparing an LUT 62a describing a relationship between a RGB input value and a CMYK output value and not subjected to color correction and an LUT 62b subjected to the color correction and by combining the output values of lattice points of the LUTs 62a and 62b using a coupling ratio α. A coupling ratio α indicative of a ratio of the LUT 62a is set to a value of 1 for each lattice point in a predetermined range from an outer edge of a RGB color space, and set to a value of 0 for each lattice points in a predetermined range from the center of the RGB color space. With respect to the other lattice points included in a range between the above ranges, the ratio of the LUT 62a is set to be smaller as the position of the lattice point is closer to the center of the RGB color space.

摘要： PROBLEM TO BE SOLVED: To correct color according to observation environment by a simple and inexpensive technique. SOLUTION: A color of an image displayed in a display 60 in a first conversion process is presumed how it is perceived under the observation environment. In an observation environment of a printed result of a second conversion process, CMYK values are specified which print the same color perceived as a presumed perceived color in the first conversion process. When it is presumed how the color is perceived under the observation environment, environment parameters L A , c, N c , F are substituted in a conversion profile, and the environment parameters L A , c, N c , F are obtained from illuminance I. Since the illuminance I is specified, based on a vision result of a test pattern, an illuminometer is not needed. COPYRIGHT: (C)2007,JPO&INPIT
