Abstract
An electronic endoscope includes a white light source, an excitation light source, an imaging device, and a light amount controller. The white light source emits white light for illuminating a subject. The excitation light source emits excitation light for generating fluorescent light on the subject. The imaging device generates first image signals by receiving reflected light of the white light, and generates second image signals by receiving the fluorescent light. The light amount controller controls the amount of the white light to lower the difference between a reflected light luminance and a fluorescent light luminance, so that a normal image corresponding to the first image signals and a fluorescent image corresponding to the second image signals that are both real-time images representing the same subject at the time of receiving the reflected light and the fluorescent light can be generated.
