Method and apparatus for skin color correction and digital photographing apparatus using both

An apparatus for skin color correction, the apparatus comprising:

• a face region detecting unit configured to detect a face region in an input image;
• a skin color extracting unit configured to extract skin colors from the detected face region;
• a principal component analyzing unit configured to perform a principal components analysis using skin colors to calculate axes for a principal component analysis (PCA) vector space and transform the extracted skin colors to the PCA space;
• and
• a skin color correcting unit configured to identify a color of the input image as a skin color using the result of the transformed skin colors to the PCA space and configured to correct a color identified as a skin color.

A computer readable recording medium encoded with a computer executable program to perform a method comprising:

• extracting skin colors;
• analyzing the extracted skin colors to calculate axes of a different vector space;
• transforming the extracted skin colors to the different vector space;
• using the result of the transformed skin colors to identify a color from an input image as a skin color;
• and
• correcting the color identified as a skin color.
