To enable well-balanced color correction by reflecting a weight coefficient for a correction-inteded color value on a color correction coefficient for correcting a particular density value of a particular color component.
A color correction coefficient generator 1 includes: an input value acquiring unit 10 that acquires an input value being correction-intended color data; a correction value calculating unit 20 for calculating a correction value through color prediction using target device based data and object device based data; a weight coefficient setting unit 30 for setting a weight coefficient for a pair of input value and correction values based on setting of an important color area input from a setting picture; a table generating unit 40 that collectively calculates correction values and weight coefficients for input values having the same density of a certain color component to generate a one-dimensional color correction table for correcting the density in the color component; and a table storing unit 50 that stores the generated one-dimensional color correction table.
