Patent ID: 7202896

Claim:
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, wherein: said number of photoelectric conversion elements are disposed in a pixel shift layout; and each of the plurality of spectral regions is disposed in correspondence with four photoelectric conversion elements and makes a first color light flux contained in the incidence light enter one of the four photoelectric conversion elements, a second color light flux enter another of the four photoelectric conversion elements, and a third color light flux enter remaining two of the four photoelectric conversion elements.
