  • Patent number: 5375000
    Abstract: A method of generating a representation of an image comprises scanning a film (2) carrying an image to which the film has been exposed to obtain signals (4,5,6) representing the color component content of the recorded image. During exposure of the image its appearance has been modified in accordance with a function characteristic of the film. The signals obtained are modified with a function (11,10,8) constituting the inverse of the film characteristic function to compensate.

  • Patent number: 5027151
    Abstract: A method of mounting a transparency for use in an input scanner comprises first inserting a transparency into an envelope. Within the envelope a film of liquid of substantially the same refractive index as the transparency is spread over the transparency. The liquid may be provided in a rupturable pod within the envelope. The transparency holder is sealed by either an integral seal or adhesive tape. The transparency holder protects the transparency from dust and scratches and helps to prevent Newtons rings occuring in the image produced when mounted in the scanner.
