=== Bayer transformation ===
The [[photodiode]]s employed in an [[image sensor]] are color-blind by nature: they can only record 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. (Actually, with most [[Sensor|sensors]] there are two green for each blue and red diode.)
 
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.
