Imaging apparatus

摘要

An imaging apparatus includes a light source unit (14) that selectively outputs white light and light in a different wavelength band to an observation target (3), an imaging unit (15) including an imaging device (15a), and a spectral image formation circuit (29, 51) that generates a spectral image signal for a specified wavelength. The imaging unit selectively obtains an image of the observation target (3) for each of first, second and third light components in a visible light region and for each of at least fourth and fifth light components in a near-infrared region. The imaging unit (15) includes first spectral devices (B+Nb, G+Ng and R+Nr) that make only the first and fourth light components enter first pixels of the imaging device (15a) and second spectral devices (B+Nb, G+Ng and R+Nr) that make only the second and fifth light components enter second pixels thereof.
