Bayer filter
A Bayer filter mosaic is a technology used in sensors for digital photography. Eastman Kodak first made the filters and patented them in the 1970s. The Bayer filter uses a grid of filters. Half of them are sensitive to green, a quarter each is sensitive to red or blue. In 2021, most image sensors used in digital cameras used a Bayer filter.
