Automatically controlling an on/off state of a light source for an endoscope during a surgical procedure in an operating room

An endoscope system capable of automatically turning on/off a light source during a surgical procedure is disclosed. This endoscope system includes: an endoscope module; a light source module coupled to the endoscope module; and a light-source control module. Moreover, the light-source control module controls an ON/OFF state of the light source by: (1) receiving real-time video images captured by the endoscope module; (2) processing the real-time video images to determine whether the endoscope module is inserted into a patient's body or is outside of the patient's body; and (3) in response to determining the endoscope module being outside of the patient's body while the light source is turned on, generating a control signal to immediately turn off the light source to the endoscope module, thereby ensuring safety of people in the operating room and preventing sensitive information in the operating room from being captured by the endoscope module.
