Abstract
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.
Claims7
An endoscope system, comprising:
- an endoscope photographing a subject in a body cavity of a patient and outputting an image signal of a predetermined number of pixels;
- a control device performing a predetermined 3D process on an output signal of the endoscope and outputting a 3D image signal obtained by the 3D process to a display device as a moving image signal of a predetermined frame rate;
- polarized glasses worn by an operator performing a surgical operation on the patient;
- sensors provided in the display device and the polarized glasses respectively;
- and
- a trigger signal generating unit generating a trigger signal for instructing zoom of a display image of the display device,
- wherein when the trigger signal generating unit generates the trigger signal, the control device identifies a fixation point of the operator in the display image of the display device based on a relationship between a detection signal of the sensor in the polarized glasses and a detection signal of the sensor in the display device at a time of generation of the trigger signal, and zooms in a periphery of the fixation point.
