ABSTRACT:
An electronic endoscope according to the present invention has a video-scope that has a first image sensor and a second image sensor, and a light supplier that selectively irradiates white light and excitation-light on an observed portion. The electronic endoscope further has a first color filter that has spectral transmitting characteristics, such that light having a first wavelength range corresponding to blue color is transmitted, and a second color filter that has spectral transmitting characteristics, such that light having a second wavelength range corresponding to green and red colors is transmitted. The electronic endoscope has a first signal processor, a second signal processor, and a third signal processor. The first signal processor generates normal image video signals. The second signal processor generates narrow-band video signals. The third signal processor generates auto-fluorescent video signals.
