Adjustment of the light spectrum is usually combined with a better and higher image resolution of the new generation endoscopes. Fujinon and Pentax use a so called super-CCD to increase the pixel resolution of the scope to 1.300.000 and 1.400.000 respectively and combined it with a DVI output signal. Olympus opted for an improved video resolution by incorporating high definition television (HDTV) in the latest processors.
