Abstract
A photographic image processing apparatus, which detects a skin domain appropriately by using a simple method, and automatically distinguishes whether or not it corresponds to a harmful image, is provided with a face information extraction unit (41) which detects a face domain of a person from inputted color image data so that color difference data of the skin is extracted from the face domain, a skin domain detecting unit (42) which detects an area that is correlated with the color difference data of the skin as a skin domain from the color image data, a domain distinction unit (43) which distinguishes domain continuity between the face domain and the skin domain, and an image distinction unit (45) which calculates the ratio of areas between the face domain and the skin domain that are distinguished as a continuous domain by the domain distinction unit (43), so that based upon the ratio of the areas, it is distinguished whether or not any non-clothed portrait image is included in the color image data.
