Initialization of the rotational angle of an image captured by a magnetically guided capsule medical apparatus is carried out with high accuracy. A capsule guiding system (1) comprises a capsule endoscope (2) composed of an imaging device for capturing an in-vivo image of an subject and a magnet having a magnetization direction fixed relatively to the imaging device, a magnetic guiding device (4) for magnetically guiding the capsule endoscope (2) by applying a magnetic field to the magnet, a display unit (62) for displaying the captured in-vivo image, and a control unit (64).The control unit (64) controls the magnetic guiding device (4) to apply a magnetic field in a reference direction to the magnet, initializes the rotational angle of the captured image by the imaging device when the magnet is magnetized in the reference direction in response to the magnetic field in the reference direction, corrects the rotation of the successive in-vivo images while referring to the captured image, and allows the display unit (62) to sequentially display the rotation-corrected in-vivo images. |
