• align the image of the observation area with an area in a reference image, the area corresponding to the image of the observation area, the reference image including an entirety of the examination subject;
• generate a navigation map from the reference image by recording, on the reference image, a position of the image of the observation area in the reference image;
• calculate a direction of movement to an unobserved area in the navigation map, the unobserved area being an area where the position of the image of the observation area is not recorded;
