Efficient interpretation of medical images containing abnormal shadow candidates is achieved. An image to be interpreted is divided into a plurality of regions of interest (R1 to R16) . Then, regions of interest (R6, R9, R11) containing the abnormal shadow candidates are determined based on detection information of the abnormal shadow candidates. When the regions of interest are displayed in enlarged view, the regions of interest (R6, R9, R11) containing the abnormal shadow candidates are displayed in descending order of the degree of malignancy of the abnormal shadow candidates, and then, the other regions of interest are sequentially displayed.
