Abstract

An image processing apparatus performs color adjustment based on an original document read by a reading device. The image processing apparatus includes an image data acquirer configured to acquire image data that is generated as the reading device reads a gradation pattern formed on a recording sheet; a density corrector configured to extract, from the image data, a color component by which a read value of a process color changes according to variations in a total spectral sensitivity characteristic of the reading device, and correct a read value of the color component to a reference density; and a color adjuster configured to perform the color adjustment on the color component, based on a difference between the read value of the color component that has been corrected to the reference density and a read value that is a reference of the reading device.
