CCD = stands for “charge-coupled device.” First invented in the 1970s, this technology uses a shift register combined with photo-diodes to create the modern day imaging device. Used in cameras, scanners, fax machines, etc. The size of the CCD chip is normally 1/4″, 1/3″ or 1/2″. As a rule of thumb, the larger the size, the higher the quality of the image produced and the higher the price. Refer to specification sheet of the camera for its CCD chip size.
