The
Iconoscope (from the
Greek:
εἰκών "image" and
σκοπεῖν "to look, to see") was the first practical
video camera tube to be used in early
television cameras. The iconoscope produced a much stronger signal than earlier
mechanical designs, and could be used under any well-lit conditions. This was the first fully electronic system to replace earlier cameras, which used special
spotlights or spinning disks to capture light from a single very brightly lit spot.
