Title:
CAMERA SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/121677
Kind Code:
A1
Abstract:
The camera system according to an embodiment of the present disclosure comprises illumination having a peak light emission wavelength at room temperature that is in the near-infrared band and an imaging device including a photoelectric conversion element. The photoelectric conversion element has spectral sensitivity at the peak light emission wavelength. The external quantum efficiency of the photoelectric conversion element has a first peak at a first wavelength longer than the peak light emission wavelength, and the external quantum efficiency at the first wavelength is greater than the external quantum efficiency at the peak light emission wavelength. The external quantum efficiency at a wavelength 200 nm longer than the first wavelength is less than 1%.
