PROBLEM TO BE SOLVED: To provide an imaging device capable of acquiring a plurality of spectral images with a proper light volume efficiency by one shot. SOLUTION: An imaging system 1A comprises an imaging device 10A. The imaging device 10A includes a spectrum prism 31A and two imaging elements 32a and 32b. A spectrum surface 31f constituted with a dichroic film is provided at the spectrum prism 31A. The spectrum surface 31f has spectral transmission characteristics, namely, wavelength characteristic for dividing wavelength bands of RGB each color, of colored filters arranged for every pixel at the imaging elements 32a and 32b. At the spectrum surface 31f, incident light Lo from an object SB branches out two optical paths La and Lb. Spectral images of the object SB proceeding the optical paths La and Lb are acquired by the imaging elements 32a and 32b. According to the arrangement, a plurality of spectral images can be acquired with a proper light volume efficiency by one shot. COPYRIGHT: (C)2004,JPO
