> This breakthrough advances an existing Kodak technology that
> has become a standard in digital imaging. Today, the design of
> almost all color image sensors is based on the Bayer Pattern,
> an arrangement of red, green, and blue pixels  that was first
> developed by Kodak Scientist Dr. Bryce Bayer in 1976. In  this
> design, half of the pixels on the sensor are used to collect green
> light, with  the remaining pixels split evenly between sensitivity
> to red and blue light.  After exposure, software reconstructs a full
> color signal for each pixel in the  final image. 
> 
> Kodak™s new proprietary technology builds on the existing  Bayer
> Pattern by adding panchromatic, or "clear" pixels to the red, green,
> and  blue pixels already on the sensor. Since these pixels are
> sensitive to all  wavelengths of visible light, they collect a significantly
> higher proportion of  the light striking the sensor. The remaining red,
> green, and blue pixels are  then used to record the color information
> of the scene.
