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

摘要

An apparatus and method of correcting skin color in an image is disclosed. The method may include 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. The different vector space may be a principal components analysis (PCA) vector space. Extracting skin colors may include detecting a face region as a skin region in an input image and extracting skin colors from the face region. A lookup table be generated according to the result of projecting the skin colors to fewer dimensions of the different vector space. Extracting skin colors may include extracting colors from a training image of skin colors.
