Patent ID: 8038608

Claim:
A body-cavity image observation apparatus, comprising: a capsule endoscope configured to capture body-cavity image data and to transmit the body-cavity image data when the capsule endoscope travels inside a body-cavity of a subject; a receiving device configured to perform a reception processing of the body-cavity image data transmitted from the capsule endoscope; and a viewer configured to be detachably connected to the receiving device and having a display device configured to display the body-cavity image data captured by the capsule endoscope, wherein the viewer includes: an antenna for directly receiving the body-cavity image data transmitted from the capsule endoscope, without transmission from the receiving device; a switching controller configured to selectively switch between a reception by the receiving device, when the viewer is connected to the receiving device, and a reception by the viewer when the viewer is not connected to the receiving device; and an identification notifying unit configured to present different identification modes which allow a sensory recognition between a case where the body-cavity image is displayed on the display device, based on the body-cavity image data received directly by the viewer, and a case where the body-cavity image is displayed on the display device, based on the body-cavity image data received by the receiving device and transmitted to the viewer.
