Patent ID: 7853048

Claim:
An iris color correction apparatus comprising: a processor for: a skin color identification means which identifies the skin color of a photographed person in an inputted image; a skin correction color calculation means which obtains a skin correction color that is an iris color of said person that should be shown in said image based on the skin color identified by said skin color identification means; a brightness estimation means which estimates a GB brightness value and forming correction object pixels before a color tone abnormality occurs in pixels of an iris portion of said photographed person from a value of said pixels of said iris portion; and a correction means which corrects the iris color of said photographed person based on said estimated GB brightness value and a correction reference color based on said skin correction color; wherein said brightness estimation means are equipped with a function that calculates said GB brightness value which is a brightness set based on G and B values from R, G, B values that create the skin color of said pixels of said iris portion; and wherein said correction means carry out conversion so that a GB brightness value of the correction reference color becomes the same as the GB brightness value of the correction object pixels based on R, G, B values of the correction reference color.
