On the basis of displacement amount information that relates to an insertion part (31) inserted into an insertion receiving object (2) and is inputted from a fiber-shaped sensor (4) and an insertion/rotation detection unit (5), a relative position information acquisition unit (61) acquires information relating to the relative position of a portion, the position of which is to be detected, of the insertion part with respect to the insertion receiving object. Using the relative position and shape information relating to the insertion receiving object and acquired by an insertion receiving object shape acquisition unit (62), an image pickup position calculation unit (63) calculates an image pickup position (P) that is at least one among an image pickup region (83) which is a region of the insertion receiving object and an image of which is picked up by an image pickup unit (34), a region (84) which is a portion of the image pickup region, and a point within the image pickup region. A display calculation unit (64) calculates weighting information relating to the image pickup position (P) on the basis of a weighting index parameter, and sets a display form on the basis of the weighting information. An output unit (65) outputs, as display information, the display form and the image pickup position (P). |
