    摘要： A capsule endoscope includes a capsule casing and interior components housed therein whose total specific gravity is set such that the capsule casing floats in liquid introduced into a subject. The capsule endoscope also includes a gravity center position setting unit that sets a position of center of gravity of the capsule casing at a decentered position so that the capsule casing is stabilized in the liquid introduced into the subject without rotating except for rotation about an axis in a direction of the center of gravity; and an imager that takes an in-vivo image in a body cavity with an imaging field being set so that a surface of the liquid is out of view when the capsule casing floats in the liquid introduced into the subject in a stabilized posture.

    摘要： An image display system has a capsule endoscope for capturing an in-vivo image of a subject, a receiving device for receiving the in-vivo image from the capsule endoscope, and an image display apparatus for displaying a group of in-vivo images of the subject. The capsule endoscope has an imaging unit having a black region which optical rays do not reach in an effective pixel region contributing to image capture. By the imaging unit, an in-vivo image including the signal level of the black region is detected. The receiving device receives an image signal of the in-vivo image. The image display apparatus obtains an in-vivo image group from the receiving device. The image display apparatus does not display an in-vivo image in the in-vivo image group determined as an image influenced by fluctuations in the power source voltage but displays a stable in-vivo image which is not influenced by fluctuations in the power source voltage.
