Data of a plurality of projected images, which is photographed from different directions, regarding an object of interest is stored in an image data storage section. A feature point coordinates acquisition section acquires the three-dimensional coordinates regarding the axis of the object of interest on the basis of the feature information and photographing directions regarding the axis of the object of interest on at least two of the plurality of projected images stored in the image data storage section. A coordinates transformation section sets the three-dimensional coordinates system, which has the axis of the object of interest as one axis, on the basis of the three-dimensional coordinates information. A reconstruction processing section reconstructs three-dimensional image data based on the set three-dimensional coordinates system from the plurality of projected images stored in the image data storage section.
