Abstract

An image processing method includes the steps of resolving the color of an image on a transparent original to extract an infrared component, detecting the level of the infrared component, detecting the defect infrared component level at the defect position on the transparent original where the infrared component level becomes lower than a first infrared level, obtaining a correction factor by calculating (first infrared component level)/(defect infrared component level) on the basis of the first infrared component level and defect infrared component level, resolving the color of the image on the transparent original to extract a visible component, detecting the visible component level of the visible component, and calculating the corrected visible component level by multiplying the defect visible component level at the defect position on the transparent original by the correction factor.
