Abstract
In an endoscope device, a light source unit is configured to sequentially emit first illumination light and second illumination light. The first illumination light includes visible light. The second illumination light includes first excitation light. At least the second illumination light out of the first illumination light and the second illumination light includes second excitation light. An excitation wavelength blocking filter has a characteristic of blocking a wavelength band of the first excitation light and a wavelength band of the second excitation light and a characteristic of transmitting a wavelength band of the visible light, a wavelength band of first fluorescence, and a wavelength band of second fluorescence. An imaging unit is configured to capture an image of the visible light, the first fluorescence, and the second fluorescence and configured to output a first imaging signal and a second imaging signal.
