| 摘要 | A color filter array includes a plurality of color filters having different center frequencies and each formed of static metal structures and an insulator, a first common electrode formed across the plurality of color filters, a second common electrode opposed to the first common electrode, separated from the static metal structures of the plurality of color filters by the insulator, and formed across the plurality of color filters, and a voltage applying unit configured to apply a voltage between the first common electrode and the second common electrode and change charge density on the surfaces of the static metal structures to thereby simultaneously change the center frequencies of the plurality of color filters. | ||
