Photo Glossary

Q. What is Demosaicing?

A. The term refers to the processing of a digital image from (usually) red, green, and blue mosaic-like patterns captured by a digital sensor. With most digital cameras, the mosaics are created by a Bayer color array, named for Bryce Bayer of Eastman Kodak, who patented a color filter array for digital sensors in 1976. Comprising red-, green-, and blue-recording pixels, the Bayer array produces three mosaics of varying densities depending on the colors of the original scene. In-camera image processing of the three mosaics uses demosaicing algorithms to reconstruct a continuous-tone image through sophisticated processes of interpolation. The result of the demosaicing process is an image that we recognize as a natural or true representation of a scene, and not a simple mosaic- or tile-like pattern of primary colors.
