Cameras
Before 1984, cameras suffered from the
technology they used: the internal picture sensor, the
tube, was large, heavy, delicate and consumed a lot of
power. The current generations of sub-miniature cameras
and camcorders are only possible because of the
development of the Charge Coupled Device, or CCD, which
is a solid-state device - an image sensor on a chip. In
stark contrast to the tube, a CCD is tiny, rugged and
requires very little power; CCDs are also far more
sensitive than tubes, allowing shooting to continue in
extremely low light levels. 1983/4 was also the period when the camera and recorder were combined to form the first camcorders, and although the very first ones still used tubes, the CCD allowed the camera part to be miniaturised along with the recorder. |
