Charge-Coupled Device (CCD) is a type of semiconductor device that’s sensitive to light. CCD consists of photodiodes that operate by converting light energy in the form of photons into an electronic charge. A charge is created when photons strike the semiconducting material. As more photons fall on the surface, more electrons are liberated, thus creating a charge that’s proportional to the light’s intensity and can be read by electronics and turned into a digital copy of the light patterns falling on the device.
CCD is used in various devices including digital cameras, video cameras, and digital imaging technologies. Quality of an image captured by a CCD depends on the resolution of the sensor.
The full form of CCD is Charge-Coupled Device
