Retired Kodak research scientist Bryce Bayer, whose invention of a color filter array enabled digital imaging sensors to capture color, has been honored by the Royal Photographic Society with its Progress Award at a ceremony in London.
The Royal Photographic Society, founded in 1853 “to promote the art and science of photography,” has chapters across the U.K. and ten regions around the world.
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 developed 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
