Abstract
An image processing apparatus performs color matching of gradation values of the same target color acquired in each of two different states. The image processing apparatus includes processing circuitry. The processing circuitry acquires, in a first state, first color values of patches respectively corresponding to first gradation values and second color values of patches respectively corresponding to second gradation values. The processing circuitry acquires, in a second state, third color values of patches respectively corresponding to the first gradation values. The processing circuitry calculates a first corrected gradation value. The processing circuitry acquires, in the second state, a fourth color value of a patch corresponding to the first corrected gradation value and fifth color values of patches corresponding to third gradation values. The processing circuitry acquires calculates a second corrected gradation value.
