Abstract: A camera system includes a light source having a peak emission wavelength at room temperature in a near-infrared region, and an imaging device including a photoelectric conversion element that converts near-infrared light into an electric charge. An external quantum efficiency of the photoelectric conversion element has a first peak at a first wavelength longer than the peak emission wavelength, and the external quantum efficiency at the first wavelength is higher than the external quantum efficiency at the peak emission wavelength.
