Sigma Buys Foveon

Sigma, a camera and lens maker, has bought Foveon, the sensor technology company that develops the sensors used in Sigma's cameras. Foveon uses three layers to detect red, green, and blue light at each pixel. Sigma claims that owning the company will allow the development of new kinds of sensors. Sigma Corporation, located in Kawasaki, Japan, has acquired 100% of the stock of the company that developed the original three-layer sensor. Sigma first worked with Foveon in 2000.
