Imaging Device
- The front end of a motion picture film scanner is similar to a telecine. The imaging system may be either a charge-coupled device (CCD), a complementary metal–oxide–semiconductor (CMOS) or cathode ray tube (CRT) imaging pick up.
- A lamp is used as the light source in a CCD imaging front end. The CCDs convert the light to the video signals.
- In a CRT imaging system the CRT (also called a Flying spot tube) is used as the light source and part of the scanning system. Photomultipliers or avalanche photodiodes are used to convert the light to electrical video signals.
- A prism and/or dichroic mirrors or colour filters are used to separate the light into the three: red, green and blue, imaging pick up devices.

Famous quotes containing the word device:
“It is my hope to be able to prove that television is the greatest step forward we have yet made in the preservation of humanity. It will make of this Earth the paradise we have all envisioned, but have never seen.”
—Joseph O’Donnell. Clifford Sanforth. Professor James Houghland, Murder by Television, just before he demonstrates his new television device (1935)
