An endoscope system includes: an insertion part having a bending part； an observation unit； an operation unit configured to operate the bending part； a driving mechanism configured to generate a driving force used to drive the bending part； a control unit configured to control the driving mechanism； and a display unit configured to display a visual field image acquired by the observation unit, wherein the control unit has a normal mode and a lock-on mode as control modes, and the control unit is configured to stop an automatic driving of the bending part temporarily and allow the operation unit to perform a resetting of an interested position when an output from the operation unit exceeds a predetermined threshold value, and resume the automatic driving on the basis of the updated interested position when an output from the operation unit satisfies a predetermined termination condition during the lock-on mode.
