CCD or Charge-coupled device is the product created by these advanced technologies, and made the digital camera possible.
When light strikes the CCD, the moving frees electrons are created, accumulate the moving frees electrons in the capacitors and by a circuit count them at regular intervals.
The combination of these measurements can reproduce a picture as a virtual mosaic of the individual point of measurements, this is the picture we see. The higher resolution of the resulting picture are the more points of measurement found on the CCD.
Increase in Camera Digital technology offer their benefit in the study of celestial objects. By digital technology, digital camera also have the capability to detect distant, by inferring their presence and comparing the light collected over time.
The telescope is one of another specialized camera that benefits from digital technology.
In traditional method, points of light are collected by a traditional camera which are mounted to telescopes then this points of light expose the film. In case of faint points of light this provide more sensitivity than the human eye but brighter points of light the image could be washed out. With Camera Digital technology digital camera using a CCD replace the film camera, continue receive and measure photons indefinitely.
To detect a very faint points of light in the sky it is possible to be done by electronically filtering out the brighter sources of light with the aid of computers.
Camera digital technology can make a highly specialized camera that are not possible with film based technology. With a CCD an image made by an X-ray film can be converted to a digital display an X-ray image on a computer screen. A modern X-ray cameras not only can instantly display an X-ray image on a computer screen, but have capability to print an image of X-ray on film, develops the film and review the tiny film image. Increase the improvements in a dentist's practice Camera Digital technology give the advantages of time saving and no waste of exposed film or development chemicals this technology also protects the environment.
