Abstract
A color inspection device includes a reading device and circuitry. The reading device images a reference object and a color detection object to obtain readings of each of the reference object and the color detection object. The circuitry corrects the readings of the color detection object by using a correction coefficient that is generated from the readings of the reference object and color information measured for each arbitrary region of the reference object.
