PROBLEM TO BE SOLVED: To provide an endoscopic device presenting to an operator a positional relationship between an image displayed on a display part and a specific part.SOLUTION: When the operator operates an operation member 223 and a distal end part 211 of a flexible part 210 is shaken to the right, an affected part 500 included in an observation image moves further to the left with respect to the observation image and leaves a range of the observation image. A system controller 301 calculates an amount of movement of the distal end part 211 of the flexible part 210 on the observation image. When the amount of movement is a value at which a first instruction sign deviates from a display range of the display image, the system controller 301 inserts in the display image a second instruction sign showing the direction in which the affected part 500 is positioned with respect to a display image. The system controller 301 composites a slave image area at the upper left of the display image. |
