3CCD 【Three-CCD】
3CCD is a technology used by some still cameras, video cameras, and camcorders. CCD refers to charge coupled device. CCD is a light sensitive semiconductor chip that converts light into electronic signals. It is the part of the camera that accepts light from the outside world and translates it into the ones and zeros that form a digital picture or video.
3CCD cameras have three separate charge-coupled devices (CCDs), each one taking a separate measurement of red, green, and blue light. Light coming into the lens is split by a special prism. It is set up to convert the light entering the camera into the three different colors; they are processed separately, and then combined into a final image. 3CCD cameras are generally provide superior image quality to cameras with only one CCD.
