CCD, or Charge-Coupled Device, is a technology used in video cameras and digital cameras to capture images. It consists of an array of light-sensitive elements that convert incoming light into electrical signals. These signals are then processed to create a digital image. CCDs are known for their high-quality image capture and low noise levels, making them popular in professional photography and scientific applications. Originally developed in the 1960s, CCD technology has evolved significantly over the years. It is commonly used in various devices, including telescopes, scanners, and medical imaging equipment. Despite the rise of other technologies like CMOS, CCDs remain valued for their superior image quality in specific applications.
