Line 10:
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 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.
