AP article here
Most sensors use the Bayer mask: Half of the millions of cells on a checkerboard grid are filtered to collect green light and a quarter each are filtered to let through red and blue light. A computer chip then reconstructs a full color signal for each pixel in the final image. The new method, which has been under development for more than five years, adds "panchromatic" cells that are sensitive to all wavelengths of visible light and collect a larger amount of light striking the sensor. Tailoring software algorithms to this unique new pattern enables faster shutter speeds, which reduces blurring when capturing a moving subject, McNiffe said.
DP Review article
Kodak Image Sensor Solutions has today announced a new Color Filter Array (CFA) layout (and image processing path) as an alternative to the widely used Bayer pattern which should provide higher sensitivity. This new layout features one 'panchromatic pixel' (monochrome) to every colored pixel (red, green or blue) and there are three proposed layouts. Kodak ISS are presenting this as a technology solution which can be applied to any size, megapixel count or type (CCD / CMOS) of sensor. Kodak claim a one to two stop improvement in sensitivity, the tradeoff is of course color resolution which is effectively a quarter of the traditional Bayer pattern. This interesting development will of course only be proven when we see it actually implemented and we can compare it to traditional Bayer. |

This is cool, I was just coming over here to post a link about this, but you beat me too it. It looks promising. I wonder if it is going to be only in Kodak cameras or if they will sell it to others?
Here is my link:

I think this is great solution. Fairly easy to implement without having to completely change the sensor architecture. It'll be interesting to see if they can keep the color sensitivity up while increasing the light sensitivity.

According to the article I read, initial implementation is likely to be in cell phone cameras, then consumer cameras before it gets to the DSLRs. Bassackwards from how new tech usually is implemented, but makes sense since those will probably get a bigger boost from the technology, and care less about the loss of color saturation (if dpreview is right that that's the tradeoff).
Once they develop the new software algorithms, should be able to retrofit this on existing DSLRs by just swapping the filter which sits on top of the sensor.

| How many of these kodak threads are going now 4? 5? |
