  • Patent number: 5146321
    Abstract: A film scanner operable according to dual line standards includes red, green, and blue linear array sensors separated by a line spacing that constitutes substantially integral first and second multiples of the line spacings of the respective line standards. More particularly, in 1125 and 1250 line television standards, the linear arrays are spaced such that the distance is substantially equivalent to 9 lines of the 1125 line standard and 10 lines of the 1250 line standard. The output signal from each linear array is registered to the same line for each standard by inserting separable sets of line delays into the signal paths from two of the linear arrays. The separable delays correspond to the first and second multiples of the respective standards. By switching between the respective sets of delays, an output signal is developed for a selected line standard.
