  • Method for transferring hot-melt ink to a recording medium
    Patent number: 5342132
    Abstract: The present invention discloses a method for thermally transferring an ink pattern to a recording medium, comprising the steps of preparing an ink sheet provided with a hot-melt and/or hot-sublimable ink layer and a transparent material sheet provided with a transparent hot-melt material layer, thermally producing an ink pattern on the transparent material layer of the transparent material sheet by heating the ink sheet with thermal head, and thermally transferring the ink pattern to the recording medium together with the transparent hot-melt material layer.

  • Image scanning apparatus
    Patent number: 5140443
    Abstract: An apparatus for scanning an image, comprising a main unit body casing, a first original platen having a transparent surface on which a light-reflective original is placed, a second original platen movable in a horizontal direction inside the main unit body casing upon which platen a light-transmissive original is placed, a light source that irradiates light to the first and second original platens, an image sensor, and an optical apparatus disposed inside the body casing, and which respectively passes reflected light from the original placed on the first original platen and light transmitted through the original placed on the second original platen to the image sensor.

  • Method of reading an image recorded in a photographic film tone characteristic correcting method in reproducing an image recorded in a photographic film
    Patent number: 5060061
    Abstract: A frame of photographic film is optoelectronically scanned after development to produce an electronic image which is analayzed to determine the exposure and development conditions of the film. Tone conversion signals are generated in accordance with the analyzed conditions to convert the tone characteristics of the electronic image to optimal values and thereby compensate for non-standard exposure and development. The electronic image of the entire frame, or alternatively only a part of the electronic image corresponding to an unexposed area of the frame, may be used to determine the development conditions.
