A digital camera contains what is known as an Image Sensor. An Image Sensor contains very small silicone chips made up of millions of photosensitive diodes, called 'Photosites'. During exposure the 'Photosites' record the intensity or brightness of the light that falls onto the sensor. Each photosite is then stored as a set of data.
