Abstract
Provided are a capsule-type image photographing apparatus and endoscopy using the same. The apparatus includes a shell unit having a globular shape and a main body unit capable of freely rotating in the shell unit. The main body unit includes an image photographing system, a wireless transmitter, a battery, a counterweight for determining the center of gravity of the main body unit, and an encapsulant for fixing the image photographing system, the wireless transmitter, the battery, and the counterweight. The apparatus may be a long-distance capsule-type image photographing apparatus or a short-distance capsule-type image photographing apparatus depending on the position of the counterweight. By use of the long- and short-distance capsule-type image photographing apparatuses, the interior of the tested person's body can be effectively photographed.
