Abstract
An imaging system includes: a first lighting device for irradiating an imaging target object with visible light; a second lighting device for irradiating the imaging target object with near-infrared light; and an image sensor for photodetecting visible light caused by the visible light and coming from the imaging target object and fluorescence caused by the near-infrared light and coming from the imaging target object during a predetermined shutter open period every frame of a predetermined period. The image sensor outputs photodetection signals corresponding to photodetection amounts of the visible light and the fluorescence. The imaging system also includes a controller that generates a composite image of a visible image and a fluorescence image based on the photodetection signals, and has a lighting controller that turns on the second lighting device with optical power corresponding to the shutter open period in synchronism with the shutter open period.
