ABSTRACT:
An electronic image pickup device for endoscopes is arranged so that at least two filters having mutually different transmitting wavelength ranges are inserted either alternatively or as a rotatable filter disc into an optical path of either an illuminating system or an image pickup system in order to make it possible to obtain either alternatingly or simultaneously color images produced by at least two kinds of rays having mutually different wavelength ranges. As an alternative the filter disc may be tilted relative to the optical axis.
