Submission + - Kodak unveils brighter CMOS color filters (

brownsteve writes: Eastman Kodak Co. unveiled what it says are "next-generation color filter patterns" designed to more than double the light sensitivity of CMOS or CCD image sensors used in camera phones or digital still cameras. The new color filter system is a departure from the widely used standard Bayer pattern — an arrangement of red, green and blue pixels — also created by Kodak. While building on the Bayer pattern, the new technology adds a "fourth pixel, which has no pigment on top," said Michael DeLuca, market segment manager responsible for image sensor solutions at Eastman Kodak. Such "transparent" pixels — sensitive to all visible wavelengths — are designed to absorb light. DeLuca claimed the invention is "the next milestone" in digital photography, likening its significance to ISO 400 color film introduced in the mid-1980's.
