Kodak develops colour-filter technology

Eastman Kodak Co has developed a colour-filter technology that increases the sensitivity to light of the image sensor in digital cameras by 2 to 4 times.

The technology allows crisp, clear images to be taken even in poor light conditions.

The new filter system will replace an industry-standard filter pattern designed by Kodak scientist Bryce Bayer in 1976.

Kodak plans to provide samples of the new technology to camera manufacturers in the first quarter of 2008. It could be incorporated in cameras and camera phones sometime next year.

The technology is expected to be of the greatest benefit to camera phones, which use smaller, and less sensitive sensors than digital cameras.

The new technology involves “panchromatic” cells which are sensitive to all wavelengths of visible light.
