Patent ID: 7486317

Claim:
A method for correcting red eye phenomenon in photographic image data, comprising the steps of: detecting a skin color pixel in the image data based on a predetermined skin color detection condition; detecting a white color pixel in the image data based on a predetermined white color detection condition; detecting a red color pixel in the image data based on a predetermined red color detection condition; dividing the image data into a plurality of blocks of a predetermined size and setting the detected red color pixel as a red eye pixel candidate and then determining the red eye pixel candidate as a red eye pixel according to a determination condition using the number of the skin color pixels and the number of the white color pixels belonging in blocks around another block in which the red eye pixel candidate belongs; and correcting the red eye phenomenon by changing a pixel value of said determined red eye pixel; and wherein said skin color detection condition is defined by using respective differences between R, G, B values of each pixel and a brightness value of this pixel; the white color detection condition is defined by using a skin color chroma value of a white color pixel candidate and an average skin color chroma value of the skin color pixels present around the white color pixel candidate; and the red color detection condition is defined by using a red color chroma value.
