1. A method of operating an endoscopic system, where the endoscopic system comprises a light source, an endoscope with a distal light entrance surface, an image sensor for capturing images through the light entrance surface, a rinsing device providing a rinsing fluid flow for rinsing the light entrance surface and a comprising a pressure sensor, and a flush detection module, the method comprising the steps of:
monitoring a pressure signal from the pressure sensor indicating the pressure in the rinsing device;
detecting an impulse event from the pressure signal, the impulse event indicating a deviation from an expected pressure at a given time;
determining that a flush impulse event has occurred by correlating the received pressure signal with a pre-defined pressure signature;
determining a slope of the pressure signal during the flush impulse event;
determining, based on the indication of a flush impulse event and the slope of the pressure signal, that a flush of the distal light entrance surface has begun; and
changing from a first video settings mode to a second video settings mode.
