To decide a rotational center for rotationally displaying on a display screen a projection image projected from a three-dimensional image.
The projection image formed by projecting an observation object 5 from the three-dimensional image in a prescribed projection direction is generated, the generated projection image is displayed in the display screen center of a display device, the area extending in the prescribed projection direction from the center of the display screen is set as a setting area S1, at least a portion of an overlap region where the set setting area overlaps the observation object is decided as a rotation center candidate region CR1, and the rotation center P1 is decided within or near the decided rotation center candidate region CR1.
