1. An image processing apparatus for performing color correction on input values of input signals in a predetermined region to be corrected in a color coordinate system, comprising:

  • a movement amount calculating section for calculating movement amounts indicating how much the input values should be moved, in accordance with a voltage corresponding to a distance between the input values and the center of the region to be corrected; and

    a color correction section coupled to the movement amount calculating section, for performing color correction on the input values, by moving the input values based on the calculated-movement amounts,wherein the movement amount calculating section calculates the movement amounts such that the movement amounts become smaller as the distance between the input values and the center of the region to be corrected becomes larger, andwherein the movement amount calculating section calculates the movement amounts in accordance with an equation having a distribution with a kurtosis greater than that of the distribution defined by the equation;

    (1−

    (the distance between the input values and the center of the region to be corrected)/(conditional data which defines the region to be corrected))×

    (a maximum distance of the movement amounts).
