CCD
A CCD is an array of light sensitive
elements that are arranged in a grid to capture images in digital cameras,
scanners, video cameras and other digital imaging applications. Each element
senses the intensity of a particular colour of light and forms one pixel. CCD
stands for Charge-Coupled Device, which is a type of image sensor commonly used
in digital cameras and camcorders. A CCD sensor works by converting light that
enters the camera lens into electrical charges, which are then transferred and
processed to produce an image.
CCD sensors
are known for their high image quality, with accurate color reproduction and
low image noise. They are also capable of capturing high-resolution images,
making them a popular choice in professional photography and videography.
However, CCD technology is being replaced by CMOS (Complementary
Metal-Oxide-Semiconductor) sensors, which offer lower power consumption and
faster processing speeds, among other benefits.
