Solid state image pickup device
First Claim
1. A solid state image pickup device comprising:
- a semiconductor substrate;
a number of photoelectric conversion elements disposed in a surface layer of said semiconductor substrate in a matrix shape having a plurality of rows and columns;
an output signal generator unit capable of generating an output signal from charges accumulated in each of said photoelectric conversion elements; and
a spectral device disposed above said semiconductor substrate and covering said photoelectric conversion elements as viewed in plan, said spectral device having a plurality of spectral regions each corresponding to a plurality of photoelectric conversion elements, each of the spectral regions spectroscopically splitting light fluxes of a plurality of colors necessary for color imaging and contained in incidence light toward different directions, each of the spectroscopically split light fluxes becoming incident upon an associated photoelectric conversion element among the plurality of photoelectric conversion elements corresponding to each of the spectral regions.

Abstract
A spectral device is disposed above a semiconductor substrate formed with a number of photoelectric conversion elements. The spectral device has a plurality of spectral regions each corresponding to a plurality of photoelectric conversion elements, each of the spectral regions spectroscopically splitting light fluxes of a plurality of colors necessary for color imaging and contained in incidence light toward different directions, each of the spectroscopically split light fluxes becoming incident upon an associated photoelectric conversion element among the plurality of photoelectric conversion elements corresponding to each of the spectral regions.
