PROBLEM TO BE SOLVED: To accurately discriminate inappropriate images.SOLUTION: An extraction module 121 is configured to extract an amount of characteristic for each low-ranked category on the basis of sample images having a first high-ranked category, second high-ranked category and low-ranked category allocated, and extract the amount of characteristic from object images of appropriateness or inappropriateness determination, and a calculation module 122 is configured to calculate a similarity level between the amount of characteristic for each low-ranked category and the object image. A determination module 123 is configured to determine the first high-ranked category to which the object image is highly likely to belong on the basis of the similarity level, and a change module 124 is configured to change the similarity level with a weight to be imparted to the similarity level of the determined first high-ranked category made greater than a weight to be imparted to that of other first high-ranked category. The determination module 123 is configured to determine the second high-ranked category to which the object image is highly likely to belong on the basis of the changed similarity level, and a decision module 125 is configured to decide appropriateness or inappropriateness of the object image on the basis of the determined second high-ranked category.SELECTED DRAWING: Figure 1
