Abstract
An endoscope system comprises first and second emitters, a fiber, and a controller. The first emitter emits illumination light to a photographic subject. The second emitter emits infrared light. Emission intensity of the second emitter is stronger than that of the first emitter. The fiber has a tip which moves in a spiral when viewed from the photographic subject during scan periods. The controller controls emission timing of the first and second emitters. Light emitted by the first and second emitters is cast from the tip of the fiber onto the photographic subject. The second emitter emits in a predetermined period of one of the scan periods, based on control of the emission timing, so as to shine infrared light with the second emitter to at least one part of the photographic subject, in order to perform marking.
Claims6
An endoscope system comprising:
- a first emitter that emits at least one of illumination light and excitation light to a photographic subject;
- a second emitter that emits infrared light, emission intensity or said second emitter being stronger than emission intensity of said first emitter;
- a fiber that has a tip which moves in a spiral when viewed from said photographic subject during scan periods;
- and
- a controller that controls emission timing of said first emitter and said second emitter;
- light emitted by said first emitter and said second emitter being cast from said tip of said fiber onto said photographic subject;
- said second emitter emitting in a predetermined period of one of said scan periods, based on control of said emission timing, so as to shine infrared light with said second emitter to at least one part of said photographic subject, in order to perform marking.
