  • Patent number: 8417025
    Abstract: The image processing apparatus according to the present invention includes a local skin color level calculating section, a local brightness deviation calculating section, and a correction amount calculating section. The local skin color level calculating section calculates, as a local skin color level, a skin color level in a predetermined local region in an image. The local brightness deviation calculating section calculates, as a local brightness deviation, a brightness dynamic range in the predetermined local region. The correction amount calculating section determines whether the predetermined local region is a skin region or not by using the local skin color level and the local brightness deviation.
