Method and apparatus for correcting the density and color of an image and storage medium having a program for executing the image correction

摘要

An image correcting method corrects the density and color of an image. The method determines, from an original color image, first image data including higher spatial frequency components of the original color image and second image data in which the high frequency component is removed or reduced. Color correction is performed on the original color image by using the first image data. Density correction is performed on the original color image by using the second image data. Thus, it is possible to perform the color correction and density correction with accuracy all of the time.
