Abstract
By disposing a plurality of magnetic-field generating elements in the inserted portion of an endoscope, and by detecting it using a magnetic-field detecting unit disposed around the inserted portion, the shape of the inserted portion inserted into a body cavity is detected and it is displayed on a display device. For this purpose, it is determined whether the inserted portion is in an effective detection range in which the insertion portion shape can be detected by a detecting unit with a practicable accuracy, and by changing the display color of the inserted portion shape based on the determination result, it can be easily checked whether the inserted portion is in the effective detection range.
