=== Bayer transformation ===

The [[photodiode]]s employed in an [[image sensor]] are color-blind by nature: they can only record [[Shades of gray|shades of grey]]. To get [[color]] into the picture, they are covered with different color filters: [[red]], [[green]] and [[blue]] ([[RGB]]) according to the pattern designated by the [[Bayer filter]] - named after its inventor. As each photodiode records the color information for exactly one [[pixel]] of the image, without an image processor there would be a green pixel next to each red and blue pixel.

This process, however, is quite complex, and involves a number of different operations. Its quality depends largely on the effectiveness of the [[Algorithm|algorithms]] applied to the raw data coming from the sensor. The mathematically manipulated data becomes the photo file recorded.
