<P>PROBLEM TO BE SOLVED: To provide an endoscope system that performs a treatment on an intended position easily and accurately. <P>SOLUTION: The endoscope system 1 comprises a first emitter (first to third lasers 33a to 33c) that emits illumination light; a second emitter (fourth laser 33d) that emits infrared light, emission intensity or the second emitter being stronger than emission intensity of the first emitter; a fiber 11 for illuminating that has a tip which moves in a spiral when viewed from the photographic subject, light emitted by the first emitter being cast from the tip of the fiber onto the photographic subject, during scan periods when the tip moves in a spiral; and a controller (61, 62, 63) that controls emission timing of the first and the second emitters. The second emitter emits in a predetermined period of the scan periods, based on control of the emission timing, so as to shine infrared light from the second emitter to at least one part of the photographic subjects through the fiber 11 in order to perform marking. <P>COPYRIGHT: (C)2010,JPO&INPIT |
