Charged Coupling Devices (CCDs) or Chips are the devices within video cameras that seek images to record. Professional grade cameras typically contain 3 chips which interpret three different signals on three different paths, while consumer grade cameras combine the signals into one path. This is one of the reasons why professional grade cameras deliver a higher clarity picture.
The image-sensing devices in todayâ€™s camcorders are Charged Coupling Devices, also known as CCDâ€™s, or chips. Camcorders generally have one or three chips, and they are generally Â½â€ or 2/3â€ in size. Professional level camcorders generally have 3 chips. The chips take the primary colors of video, red, green, and blue, and transform them into electronic signals that the camcorders put to tape. With a 3-chip camcorder, each color has its own path, while a single chip camera puts all three colors on the same path. By keeping the colors separate, 3-chip cameras tend to have an advantage in clarity over 1-chip cameras.
