Abstract
An image processing apparatus includes circuitry that estimates a first geometric transformation parameter aligning first output image data with the original image data, the first output image data being acquired by reading a first output result, and a second geometric transformation parameter aligning second output image data with the original image data, the second output image data being acquired by reading a second output result. The circuitry associates, based on the first and second geometric transformation parameters, combinations of color components of the first and second output image data, corresponding to pixels of the original image data, to generate pixel value association data, and determines, based on the pixel value association data, a mapping for estimating color drift between the first output image data and the second output image data from the original image data. The original image data is subjected to color conversion based on the mapping.
