Abstract: An endoscopic system and method for its operation are disclosed. The system comprises a light source, an endoscope with a distal light entrance surface, an image sensor capturing images through the light entrance surface and a rinsing device for providing a rinsing fluid flow for rinsing the light entrance surface, the method including the steps of receiving a sensor signal from a sensor detecting a user input starting a rinsing operation of the rinsing device, and, upon receipt of the sensor signal, changing an illumination mode of the light source from a first illumination mode to a second illumination mode and/or changing the video capture from a first video capture mode to a second video capture mode. The second illumination and/or video capture mask undesirable visual artifacts which can occur when collecting images with a rolling shutter sensors while performing a liquid flush of the light entrance surface.
