Matsushita (Panasonic) developed a new robust image sensor. The new image sensor would not decay under harsh sunlight for more than 20 years.

Unlike traditional image sensors with polymer onchip microlenses and dyed color filters, the revolutionary MOS image sensor has digital-microlenses and photonic color filters, both made of inorganic materials that are inherently fade-resistant and quite robust. Conventional MOS image sensors require polymer onchip microlenses and dyed RGB color filters, which are fragile and extremely susceptible to sunlight exposure and a change in temperature.

When the new Panasonic image sensor will be available in digital cameras is not disclosed yet.
