Apparatus and method for generating density correction curve

Abstract

Abstract PROBLEM TO BE SOLVED: To provide a density correction curve generating device and method that can properly correct the density of an image. SOLUTION: A correction object image is divided into areas (step 31). A high density area and a low density area are eliminated from the division areas and a standard density area is extracted (step 32). Furthermore, a principal image part is extracted (step 33). A representative density is calculated on the basis of the standard density area and the principal image part (step 34). A density correction curve is generated so that the calculated representative density reaches an object density (step 35). Using the generated density correction curve corrects the density of the correction object image.
