Provided is an endoscope system wherein, when a trigger signal generating unit of an endoscope 10 generates a zoom-in or zoom-out trigger signal, a control device 40 identifies the fixation point of an operator in a display image of a display device 30 on the basis of a relationship between a detection signal from a sensor in polarized glasses 50 and a detection signal from a sensor in the display device 30 at the time of generation of the trigger signal, and zooms in or zooms out the peripheries of the fixation point. As a result, convenience of the endoscope system including an 8K endoscope is further enhanced.
