In an in-space viewpoint control device, a viewpoint control means comprises a recommend vector setting means, a viewpoint information determination means, a viewing point order calculation means, a viewpoint pass generating means, and a relevant information visualization control means. The recommend vector setting means sets recommend vectors for the object which reflects the intentions of the content designer. The viewpoint information determination means is determines a viewing direction and a viewpoint position in the space for viewing the object on the basis of the recommend vector information. The viewing point order calculation means is responsive when a plurality of recommend vectors are being set, as it determines a rotation order for each viewing point being determined in accordance with the recommend vector. The viewpoint pass generating means calculates an appropriate shifting pass for the viewing point following the calculated rotation order, such that the viewing point is shifted smoothly. The relevant information visualization control means is responsive to the user's decision of having relevant information displayed along with the object, as it controls their disposition, the place and direction of the viewing point such that they do not interfere with each other.
