A weighting processing unit performs a weighting process for an individual lesion similarity which is a similarity between a target lesion and a case lesion of the same type, using a first weighting coefficient corresponding to the degree of contribution of each type of lesion to the specification of a disease name, to calculate a processed individual lesion similarity corresponding to a first purpose of specifying the disease name. In addition, the weighting processing unit performs the weighting process for the individual lesion similarity, using a second weighting coefficient corresponding to the degree of contribution of each type of lesion to the specification of a severity, to calculate a processed individual lesion similarity corresponding to a second purpose of specifying the severity. A total similarity between a target image and a case image is calculated for each purpose on the basis of the processed individual lesion similarities.
