The implementation of feature values is implemented for each region, and an evaluation value of skin characteristic value is calculated, thereby making it possible to more accurately than when not performing the evaluation of the skin was evaluated by the color area division.
Dividing means divides the captured image of skin into a plurality of regions. For example, the area separating unit (23) into the region of the skin region and the non-skin region (e.g., pores, spots, body hair and other regions) in the planar direction. Feature value calculation means (24) on the nature of eigenvalues ​​divided by the area dividing unit (23) calculates the color of each region related to, e.g., associated with the skin brightness, color, transparency and other characteristic values. Calculating means (25) using the characteristic value calculating means (24) calculates the feature values ​​to calculate the evaluation value of skin. In this way the implementation of feature values ​​calculated for each region, and calculates an evaluation value of skin characteristic value, thereby making it possible to more accurately than when not performing the evaluation of the skin was evaluated by the color area division.
