Kodak are not standing still they are deriving more & more of their revenues from alternative technologies like OLEDs and here is their latest refinement of the bayer pattern they invented.

ROCHESTER, N.Y., June 14, 2007 – Eastman Kodak Company (NYSE:EK) today introduced a groundbreaking advancement in image sensor technology that will help make dark, blurry digital photos a thing of the past.

Kodak’s new sensor technology provides a significant increase in sensitivity to light when compared to current sensor designs. With this new technology, users will realize a 2x to 4x increase in sensitivity (from one to two photographic stops), which will improve performance when taking pictures under low light and reduce motion blur when imaging moving subjects. In addition, this technology enables the design of smaller pixels (leading to higher resolutions in a given optical format) while retaining imaging performance.

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.

Go research the rest on the net.

Kind of a Dalsa design, eh?

Dalsa? Naw, looks more like a shoebox version of my Ektasound 140 Super8 Sound movie camera, right down to the zoom lens:

Do you think red shoulderpad will work with that????

The Kodak advancement referred to in Nova's post above is a refinement of the Bayer filter array and is described by the inventors in more detail here:

It holds the promise of increased sensitivity by using panchromatic (clear) pixels along with red, green, and blue.
Since it involves changes in the demosaicing algorithm, I'd be interested in Graeme's opinion of this and whether it might find it's way into future Mysterium sensors.

thanks for the link, interesting read about the clear pixels

there was a comment after the article about putting nd filters for the extreme highlights on some of the clear pixels to increase dynamic range - i wanted to see what that would look like and also thought of making one larger pixel in the center for taking in more light in the shadows
