How a Charge Coupled Device (CCD) Image Sensor Works
How a Charge Coupled Device (CCD) Image Sensor Works50 YEARS of the CCDTELEDYNE IMAGING2 area defined by one of the pixels will be converted into one (or more) electrons and the number of electrons collected will be directly proportional to the intensity of the scene at each pixel. When the CCD is clocked out, the number of electrons in each pixel are measured and the scene can be reconstructed.(Above) Teledyne e2v CCD47-20 back- illuminated 1024 x 1024 pixel m pixel Boyle and George E. Smith invented the Charge - Coupled Device (CCD) in 1969 in the United States at AT&T Bell Labs. In 1970, Boyle and Smith submit-ted a paper on their invention of the CCD to the Bell System Technical Journal.
Jan 22, 2020 · processing on the image to determine the real or true intensity of for example different objects in an image. NOISE There are a number of contributions to the noise performance of a CCD. DARK CURRENT Dark current is thermally generated noise. At room temperature, the noise performance of a CCD can be thousands of electrons per pixel per second.
