Abstract
An imaging device includes: an imaging sensor; a color filter including first band filters and a second band filter configured to transmit narrowband light having a maximum value of a transmission spectrum outside a range of the wavelength band of the light that passes through each first band filter; a first light source unit; a second light source unit configured to radiate light having an upward projecting distribution of a wavelength spectrum in relation to intensity and having a narrowband light spectrum narrower than the broadband; and a control unit configured to cause the first light source unit and the second light source unit to radiate the beams of light simultaneously, wherein a peak wavelength of the light radiated by the second light source unit is an infrared region or a near-infrared region.
