[Problem] To enable the suitable visualization of a structure in accordance with the distance between the structure and the viewpoint position of a virtual endoscope. [Solution] A structure extraction unit (24) extracts a structure from a 3D medical image (M), and a viewpoint determination unit (26) determines the viewpoint position and the line-of-sight direction of the virtual endoscope image. An image generation unit (27) calculates the distance between the extracted structure and the viewpoint position (P1), determines display attributes of the extracted structure on the basis of a plurality of display attributes that differ in accordance with the distance from the viewpoint position and that are defined in accordance with distance and structure, and generates from the 3D medical image (M) a virtual endoscope image (G1) containing the structure having the determined attributes. A display control unit (28) displays virtual endoscope images (G0) at a WS display (10). |
