Abstract
A color correction coefficient generating apparatus includes a first color information obtaining unit that obtains pieces of color information to be corrected in a color space made up of plural color components including a specific color component, a second color information obtaining unit that obtains pieces of color information used for correction corresponding to the pieces of color information to be corrected in the color space, a weighting coefficient obtaining unit that obtains weighting coefficients corresponding to the pieces of color information to be corrected, on the basis of a position relationship between colors represented by the pieces of color information to be corrected and a specified color region and weights that are based on densities of the colors represented by the pieces of color information to be corrected, and a generating unit that generates color correction coefficients for correcting specific density values.
