THE FUTURE IS HERE

Digital Camera Sensor Technology – Part 3 CCD Sensors explained

Continuing with my review of camera sensor technology I attempt to show how this CCD sensor captures and shifts out the electrons to a capacitor/amplifier before being sent to the analogue to digital convertor which gives a digital value proportional to the light which fell on that pixel during the exposure cycle. It is quite a complex operation and I have tried to keep it as simple as possible yet still retain some of the key points of this technology. It is my understanding of how the device works and may not fully represent a real world device as manufacturers quite often change designs to improve efficiency and reduce noise.
