ABSTRACT:
A 3D dynamic image production system capable of automatically producing the appropriate viewpoint data for observing the target object. In this system, object data indicating objects and viewpoint data indicating a viewpoint are inputted, and an imaging target object to be imaged is specified. Then, whether a blocking of a viewing axis with respect to the imaging target object by another object is judged, where the viewing axis is determined according to the viewpoint data, and the viewpoint data is changed when it is judged that the viewing axis is blocked. The 3D dynamic image of the imaging target object is then produced according to a new viewing axis determined from the changed viewpoint data.
