Line Array CCD

The Robert Bosch GmbH, Fernseh Div., which later became BTS inc. - Philips Digital Video Systems, Thomson's Grass Valley and now is DFT Digital Film Technology introduced the world's first CCD telecine (1979), the FDL-60. The FDL-60 designed and made in Darmstadt West Germany, was the first all solid state telecine.

Rank Cintel (ADS telecine 1982) and Marconi Company (1985) both made CCD Telecines for a short time. The Marconi model B3410 telecine sold 84 units over a three-year period, and a former Marconi technician still maintains them.

In a charge-coupled device Line Array CCD telecine, a “white” light is shone through the exposed film image into a prism, which separates out the image into the three primary colors, red, green and blue. Each beam of colored light is then projected at a different CCD, one for each color. The CCD converts the light into electrical impulses which the telecine electronics modulate into a video signal which can then be recorded onto video tape or broadcast.

Philips-BTS eventually evolved the FDL 60 into the FDL 90 (1989)/ Quadra (1993). In 1996 Philips, working with Kodak, introduced the Spirit DataCine (SDC 2000), which was capable of scanning the film image at HDTV resolutions and approaching 2K (1920 Luminance and 960 Chrominace RGB) × 1556 RGB. With the data option the Spirit DataCine can be used as a motion picture film scanner outputting 2K DPX data files as 2048 × 1556 RGB. In 2000 Philips introduced the Shadow Telecine(STE), a low cost version of the Spirit with no Kodak parts. The Spirit DataCine, Cintel's C-Reality and ITK's Millennium opened the door to the technology of digital intermediates, wherein telecine tools were not just used for video outputs, but could now be used for high-resolution data that would later be recorded back out to film. The DFT Digital Film Technology, formerly Grass Valley Spirit 4k2kHD (2004) replaced the Spirit 1 Datacine and uses both 2K and 4k line array CCDs. (Note: the SDC-2000 did not use a color prisms and/or dichroic mirrors.) DFT revealed its new scanner at the 2009 NAB Show, Scanity. The Scanity uses Time Delay Integration (TDI) sensor technology for extremely fast and sensitive film scans. High speed scanning 15 frame/s @ 4K; 25 frame/s @ 2K; 44 frame/s @ 1K.

Famous quotes containing the words line and/or array:

    We are apt to say that a foreign policy is successful only when the country, or at any rate the governing class, is united behind it. In reality, every line of policy is repudiated by a section, often by an influential section, of the country concerned. A foreign minister who waited until everyone agreed with him would have no foreign policy at all.
    —A.J.P. (Alan John Percivale)

    Any one who knows what the worth of family affection is among the lower classes, and who has seen the array of little portraits stuck over a labourer’s fireplace ... will perhaps feel with me that in counteracting the tendencies, social and industrial, which every day are sapping the healthier family affections, the sixpenny photograph is doing more for the poor than all the philanthropists in the world.
