Patent ID: 8134191

Claim:
A solid-state imaging apparatus that performs color imaging using visible light and imaging using infrared light, the solid-state imaging apparatus including a plurality of two-dimensionally arranged pixel cells, in each of which a filter mainly transmits one of visible light and infrared light, wherein: arrangement of the filters is a combination of (i) a first unit of arrangement where a plurality of filters that mainly transmit visible light are arranged and (ii) a second unit of arrangement where a filter that mainly transmits visible light and a filter that mainly transmits infrared light are arranged, a multilayer interface filter that composes each of the filters that mainly transmit visible light includes two λ/4 multilayer films and a dielectric layer sandwiched therebetween, the dielectric layer having an optical film thickness different from an optical film thickness of each layer that composes the λ/4 multilayer films, and each of (i) the two λ/4 multilayer films that are included in each of the filters that mainly transmits visible light and (ii) a λ/4 multilayer film that composes the filter that mainly transmits infrared light includes two types of dielectric layers that have been alternately laminated, each type of dielectric layers being composed of inorganic materials, and having a same optical thickness and a different refractive index from each other.
