1. A method of correcting skin color in an image, the method comprising: extracting skin colors with a skin color extracting unit; analyzing the extracted skin colors to calculate axes of a different vector space, wherein the analyzing utilizes: a principal component analyzing unit configured to perform a principal components analysis (PCA) using skin colors extracted by the skin color extracting unit to calculate axes for a principal component analysis vector space; and a processor of an image processing device; transforming the extracted skin colors to the PCA 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.
