A method and a system for providing video signals to video displays includes the steps of receiving at least one input video signal, dithering the non-uniformity color correction, applying the non-uniformity color correction to the input video signal to generate a color corrected video signal, and increasing a frame rate of the color corrected video signal. At least one of the setting elements of the microscope is operatively connected to the camera in such a way that a specific image mode of the camera is settable as a function of a modification of the microscope setting. A pressure-resistant housing is configured to protect an interior of the module insert from the pressure of the fuel.
