Abstract
An endoscope system includes a first light source that emits visible light, a second light source that emits non-visible light, an image sensor that generates a first image including a subject through first photoelectric conversion using the visible light and generates a second image including a subject that emits fluorescence emission light due to excitation by the non-visible light through second photoelectric conversion using the non-visible light, and an output device that alternately switches between and outputs the first image and the second image. The second light source starts light emission by a predetermined time before start of the second photoelectric conversion due to driving of the driving circuit.
