Detailed explanation-1: -A CCD sensor breaks the image elements into pixels. Each pixel is converted into an electrical charge whose intensity is related to the intensity of light captured by that pixel.
Detailed explanation-2: -A charge-coupled device (CCD) is a semiconductor device capable of both photo-detection and memory, which converts light to electronic impulses. One-and two-dimensional CCD arrays are used in scanners to perform the first stage in converting an image into digital data.
Detailed explanation-3: -The fundamental light-sensing unit of the CCD is a metal oxide semiconductor (MOS) capacitor operated as a photodiode and storage device.
Detailed explanation-4: -CCD stands for Charged Coupled Device. CCD uses an actual lens to reduce the entire image onto the imaging sensor. This method is excellent for capturing high-resolution details and widening color space. In many cases, CCD scanners are preferred when the highest image quality is paramount.
Detailed explanation-5: -Charge coupled devices, or CCDs, are sensitive detectors of photons that can be used in telescopes instead of film or photographic plates to produce images. CCDs were invented in the late 1960s and are now used in digital cameras, photocopiers and many other devices.
