Abstract: A capsule endoscope system includes: a capsule endoscope; a receiving unit that receives an image signal of an object transmitted wirelessly from the capsule endoscope; an image display unit that displays an image based on the image signal received by the receiving unit; a position detection unit that detects a position of the capsule endoscope; and a control unit having a first determination unit that determines whether normal display of the image based on the image signal is possible and having a second determination unit that determines whether normal position detection for the capsule endoscope is possible by the position detection unit. The control unit causes the image display unit to start display of the image based on the image signal when the normal display of the image based on the image signal is possible and the normal position detection for the capsule endoscope is possible.
