Abstract
A color correction apparatus and method thereof in an image system are capable of automatically processing color correction by storing reference colorimetric data regarding a predetermined test pattern for estimating the color correction in a storage medium, and then scanning the estimating test pattern so that the color correction can be performed by minimizing an error between the reference data and the scanning data obtained by scanning the test pattern. As a result, color correction can be performed without using an optical densitometer or a colorimeter, and the operation for correcting the color can be performed without knowledge of the color coordinate system or the color signal.
