ABSTRACT:
A continuous-motion line-array telecine images the film image onto three linear array sensors having respective color filters. Vertical scanning is provided by the continuous motion of the film. The sensors can be spaced by an amount equivalent to a given number of line scans for one film and television format combination. To accommodate other formats, a cylindrical lens pair is selectively included, which provides a desired magnification in the vertical direction but not the horizontal direction. The sensor spacing does not then need to be changed and the sensors can be made as an integral device, so that they can be constructed closer together and are likely to have more similar characteristics.
