Abstract
An endoscope system in accordance with an embodiment of the present invention includes an endoscope with a monochrome image pickup device for capturing reflected light and fluorescence from the body cavity, an excitation light cut filter which is installed in front of the image pickup device for shielding excitation light, and an endoscope ID which includes information on the type of the endoscope. A light source unit includes a first switching filter that irradiates light including excitation light for a fluorescent image mode and a filter for generating continuous light for a normal-light image mode. The filters switch based between the fluorescent image mode and the normal-light image mode. A second switching filter with a limiting filter that limits certain wavelengths of excitation light of the first switching filter is provided. The limiting filters are switched according to the endoscope ID or observation state in the fluorescence mode. The excitation light cut filter shields excitation light generated by the first and second filters.
