[Problem] When comparing two images taken of the same subject at different times using tomographic images, to accurately extract the tomographic image at the position that corresponds to the selected tomographic image and to comparatively display same. [Solution] First tomographic image information, which specifies a first tomographic image contained in a first image, and first region of interest information, which specifies a first region of interest on the first tomographic image, are acquired. The amount of image deformation for deforming either the first image or the second image so that the first image and the second image coincide is calculated. In the second image, a tomographic picture that corresponds to the first tomographic image is specified as the second tomographic image on the basis of the amounts of image deformation for multiple positions in the first region of interest and the first tomographic image information, and a region of interest in the second image that corresponds to the first region of interest is specified as the second region interest. The second tomographic image, in which the first tomographic image and the second region of interest are imaged, is displayed. |
