What does CCD mean?

CD stands for Charge Coupled Device. In a digital camcorder the CCD is the light-sensitive chip used to capture images; an optical sensor converts light into electronic signals for high-quality images. In essence CCDs control how an image is captured. A single CCD camcorder is sufficient for most people although often the resolution is not as high as a decent stills camera. With three CCDs, each captures a different colour, resulting in greater colour accuracy and a sharper image; more CCDs ensure better picture quality. Once very costly, 3-CCD models are more widely available now.
