Eastman Kodak has developed digital camera technology that nearly eliminates the need for flash photography, part of the company's effort to make money from its deep patent portfolio.

The world's biggest maker of photographic film says its proprietary sensor technology significantly increases sensitivity to light. Image sensors act as a digital camera's eyes by converting light into an electric charge to begin the capture process.

Kodak, which is in the last year of a lengthy and expensive transformation into a digital photography company as its film business shrinks, intends to lean on its wealth of intellectual property to boost its bottom line, expecting up to $250 million this year alone in royalties and related revenues.

For example, CE Antonio Perez has previously said its new inkjet printer strategy grew out of the discovery of existing, unused patents for printer ink.

"Our strategy is to get it out of the lab and onto the street," said Chris McNiffe, GM of Kodak Image Sensor Solutions.

Analysts have looked at that outlook sceptically, since Kodak has given few details about the types of patents it intends to exploit. Moreover, they say licensing contracts are incremental and hard to bank on in the long term.

"They have been guarded about their portfolio, with certain degrees of success," said analyst Christopher Chute of research firm IDC. "But at the end of the day you need to have invented something or have some kind of intellectual property in order to maintain a market position."

Competitive-edge

Kodak said the new technology advances an existing Kodak standard in digital imaging. Today, the design of almost all colour image sensors is based on the "Bayer Pattern", an arrangement of red, green and blue pixels first developed by Kodak scientist 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 colour signal for each pixel in the final image. Kodak's new proprietary technology adds "clear" pixels to the red, green and blue elements that form the image sensor array, collecting a higher proportion of the light striking the sensor.

Manufacturing customers interested in the design will likely get a chance to sample it in early 2008, but Kodak's McNiffe was unsure when devices using the technology would be in stores. The technology could be used at first in devices such as cellphones and eventually products made for industrial and scientific imaging.

IDC's Chute said Kodak would probably use the technology for its own cameras, hoping to gain a competitive-edge.

"The potential [for its success] is always there, but it's a wait-and-see thing," he said.

It is interesting that Kodak would do such a thing. Many over at Dpreview have been speculating on the next Nikon flagship camera and what sensor it will carry. Some have suggest that it would carry a Kodak sensor. Who knows? Either way, this is a new way of saying 'low light photography.'
