Abstract
An image acquisition system includes: a first narrowband light source that emits first narrowband light for exciting a luminescent agent that exists in an observation target and emits light having a wavelength belonging to a visible light wavelength band; a second narrowband light source that emits second narrowband light in a wavelength band of ±30 nm of a peak light emission wavelength of the luminescent agent; a broadband light source that emits broadband light for illuminating the observation target; a first image sensor on which an image of light in a light emission wavelength band including a wavelength corresponding to light emitted from the luminescent agent is formed; and a second image sensor including one or more image sensors on which an image of light in a wavelength band other than the light emission wavelength band is formed.
