Abstract: The disclosure extends to methods, systems, and computer program products for detecting whether an illumination source of an endoscope is in use (inside the body of a patient) versus not in use (outside the body of a patient). The disclosure relies on the fact that the working environment is lit solely by the endoscope and its components.

Conversely, when the illumination source is turned off and the endoscope is inside the body, the sensor will not detect any light (or will detect only a very low level of light).
