dynamic range of digital image sensors
Hello Ng,
My questions regards the dynamic range of digital image sensors (CCDs and CMOS). I understand that this is mostly limited by the size of the capacitor / well that holds the electrons and the amount of electronic noise produced by the sensor. But if the capacitor size is a limiting factor, why donīt the manufacturers use larger ones ? Is there a special relationship between the size of the capacitor and the size of of each pixel that keeps them from doing so ? Thanks for your input! Mr.Adams |
