Abstract
An image processing apparatus includes an image forming device, a reading device, and circuitry. The image forming device is configured to form a first pattern on a recording medium. The first pattern includes a plurality of patches in a plurality of tones. The reading device is configured to read the first pattern. The circuitry is configured to acquire read data of the first pattern from the reading device. The read data includes red, green, and blue (RGB) color space values. The circuitry is further configured to: correct the read data based on information indicating a relationship between a color and a position in the first pattern to reduce variation in readings due to a read position of the first pattern; convert the read data corrected into device-independent data; and adjust a color reproduction characteristic of the image forming device based on the device-independent data.
