ABSTRACT:
Methods of correcting color images often involve a complex interrelation of many color components and require extensive training to be able to be fully utilized. The present disclosure involves a simplified form of color correction. From the selection of a series of actual (16,17) and desired (18,19) colors, a series of contrast and brightness values are derived, which can then be applied to the color image to produce the color corrected image.
