CCD cameras, or Charge-Coupled Device cameras, are a type of digital camera that use a special sensor to capture images. This sensor converts light into electrical signals, which are then processed to create a digital image. CCD technology is known for its high-quality image capture, making it popular in professional photography and scientific applications. These cameras are often used in various fields, including astronomy, medical imaging, and surveillance. Unlike other types of sensors, CCDs are praised for their ability to produce low noise and high sensitivity, resulting in clearer images, especially in low-light conditions.
