Abstract
An image processing apparatus comprises a generation unit configured to generate correction information for reducing density change in image formation using a printing material including a plurality of colors. The generation unit generates correction information, sequentially in ascending order from a region of a smaller number of printing materials in a read-out image acquired by reading an image formed using a printing material including a plurality of colors, the correction information corresponding to a printing material for which correction information has not been generated among the printing materials used for the region.
