A image pickup system has an image pickup apparatus including a spectral prism and two image pickup devices. The spectral prism has a spectral face formed from a dichroic film. The spectral face has spectral transmission characteristics of color filters disposed for each pixel in the image pickup devices, that is, a wavelength characteristic which divides a wavelength band of each of RGB colors. Incident light from a subject is split into two optical paths by the spectral face, and spectral images of the subject traveling in the optical paths are obtained by the image pickup devices. Thus, a plurality of spectral images can be obtained in one shot with excellent efficiency regarding the quantity of light.
