Retired Kodak researcher honored key digital camera technology

Bayer invented the color filter array that bears his name (the Bayer filter), which is incorporated into nearly every digital camera and camera phone on the market today. Described in U.S. Patent 3,971,065, “Color Imaging Array,” filed in 1975, color filters are arranged in a checkerboard pattern to best match how people perceive images, and provide a highly detailed color image.

The Bayer Filter enables a single CCD or CMOS image sensor to capture color images that otherwise would require three separate sensors attached to a color beam splitter – a solution that would be large and expensive. The red, green, and blue colors of the Bayer filter are fabricated on top of the light-sensitive pixels as the image sensor is manufactured, a process pioneered by Kodak.

“The elegant color technology invented by Bryce Bayer is behind nearly every digital image captured today,” said Dr. Terry Taber, Kodak Vice President and Chief Technology Officer. “Bryce Bayer is very deserving of this prestigious recognition and all of us at Kodak join the Royal Photographic Society in saluting him.”

In addition to his work on digital color imaging, Bayer developed widely cited algorithms for storing, improving, and printing digital images.

Bayer joins the growing list of Kodak researchers who have been honored by the imaging industry for their contributions to the technology and standards used in digital cameras.
