The short version is that by replacing 1/2 of the sensor elements of a bayer
pattern with panchromatic elements, Kodak claims a 1-2 stop boost in

"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."
