Eastman Kodak Company is working to enable a new level of low-light sensitivity for applied imaging markets through the integration of two advanced image sensor technologies.

By combining the KODAK TRUESENSE Color Filter Pattern - a technology that increases a color sensor's sensitivity to light - with Kodak's latest Interline Transfer CCD pixel design, light starved applied imaging applications such as traffic monitoring and surveillance can look forward to a new class of cameras that will provide improved image quality under demanding lighting conditions. The first public demonstration of this technology integration, based on the currently available 1080p format KODAK KAI-02150 Image Sensor, will be shown at Kodak's exhibit at the Vision 2009 trade show held November 3 - 5 in Stuttgart, Germany.

“Improving camera performance for low light imaging is a key issue for applied imaging applications such as security and traffic monitoring,“ said Chris McNiffe, general manager of Kodak's Image Sensor Solutions group. “Deploying Kodak's new Color Filter Pattern technology on our most advanced Interline Transfer CCD platform will provide these markets a new level of imaging performance - availability of color information in low light where it wasn't available before. This integration is another example of Kodak's commitment to develop and deploy our most advanced technologies for these key markets.“

The KODAK TRUESENSE Color Filter Pattern increases a sensor's light sensitivity by adding panchromatic, or “clear“ pixels to the red, green, and blue elements that form the image sensor array. Since these pixels are sensitive to all wavelengths of visible light, they collect a significantly higher proportion of the light striking the sensor. By matching this pixel arrangement with advanced software algorithms from Kodak, users can realize a 2x to 4x increase in light sensitivity (from one to two photographic stops) compared to a standard Bayer color sensor, providing a critical performance advantage for light starved applications.

The KODAK KAI-02150 Image Sensor provides full support for the 1080p image capture standard, supporting 1920 x 1080 pixel (16:9 aspect ratio) image capture at 60 frames per second - twice the frame rate of standard HD video. The sensor also provides broad dynamic range and excellent imaging performance - parameters that are critical for applied and professional markets.

The KAI-02150 is part of a full family of CCD image sensors based on the KODAK TRUESENSE 5.5-Micron Interline Transfer CCD Platform, an advanced technology that offers significant advances in pixel size, frame rate, and image quality compared to Kodak's previous generation of technology. This family of five interline CCD image sensors - ranging from the 1-megapixel KODAK KAI-01050 Image Sensor to the 8-megapixel KODAK KAI-08050 Image Sensor - all share common pin-out and electrical configurations, allowing camera manufacturers to leverage camera designs across the entire sensor portfolio to shorten time-to-market for new camera products.

In addition to demonstrating use of the KODAK TRUESENSE Color Filter Pattern on the KAI-02150 Image Sensor at the Vision 2009 trade show, Kodak will have its full portfolio of Interline Transfer, Full Frame, and Linear CCD Image Sensors on display at this event, held this year November 3 - 5 in Stuttgart, Germany. Kodak will also present a talk on this technology demonstration as part of the trade show's Industrial VISION Days presentations on Thursday, November 5.
