Abstract

A capsulated body having a facility, which acquires biomedical information through endoscopic examination or the like, incorporated therein is inserted into a duct within a living body. Whether the capsulated body has halted for a certain period of time is detected from the time-varying position of the capsulated body or a time-passing change in an image. If it is judged that the capsulated body has halted at a stenosed region or the like, the fact is notified so that the capsulated body can be collected immediately.
