Abstract

An image processing apparatus includes a generation unit generating a first chart image having a plurality of patches with different tone values, an obtaining unit obtaining measurement values acquired by measuring a test chart created by forming the first chart image on a medium, the measurement values indicating densities of a color material in regions of the test chart corresponding to the respective patches, and a selection unit selecting at least one tone value in a range in which an output characteristic of the image forming apparatus derived based on the tone values of the respective patches and the measurement values satisfies a predetermined condition. The generation unit generates a second chart image having a patch corresponding to the selected tone value included and at least one patch corresponding to the tone value outside the range in which the output characteristic satisfies the predetermined condition is omitted among the patches.
