1. Field of the Invention
The present invention relates to an image display apparatus that displays an in-vivo image obtained by a capsule endoscope inserted in a subject body, and a capsule endoscope system.
2. Description of the Related Art
Conventionally, in an examination of a subject using a capsule endoscope that is inserted in a subject body and captures an image inside the body, an in-vivo image group obtained by the capsule endoscope is observed in a pseudo moving image or a still image list to select what has an abnormal observation. This operation is called “observation.”
When an abnormal observation is found, in order to identify in which portion (i.e. which organ) in the subject body it is found, a method of estimating the position of each in-vivo image captured in the subject and a method of creating the trajectory of the capsule endoscope in the subject have also been proposed (for example, see Japanese Laid-open Patent Publication No. 2006-75301, Japanese Laid-open Patent Publication No. 2007-283001 and Japanese Laid-open Patent Publication No. 2008-100075).
