 In the raw file, each of 4.7 million triples of digitized data from the sensor contains three measurements taken at three different depths within the silicon chip.The penetration of light into silicon is dependent on the wavelength of the light; therefore, the red, green, and blue values can be independently calculated at each of 4.7 million locations.This is in contrast to the approach utilized in a Bayer sensor, which can only measure one color channel at each location, and must interpolate the remaining color information based on the neighboring values.
