  • Patent number: 8994931
    Abstract: A paper sheets identification apparatus to identify the monetary kinds of paper sheets and to determine whether or not they are genuine provides for a simplified and general purpose detection to be performed irrespectively of the difference in the portions of each of such sheets in which their optical characteristics are arranged. The paper sheets identification apparatus includes a light emitting element; a light receiving element disposed opposite to the light emitting element with the transport path of such sheets interposed therebetween; a plurality of reflective mirrors to conduct light emitted from the light emitting element to the light receiving element; and a guide to move at least one of the reflective mirrors to the direction crosswise to the transport direction of such sheets within a surface in parallel with the carriage surface.
    Type: Grant
    Filed: September 14, 2011
    Date of Patent: March 31, 2015
    Assignee: Hitachi-Omron Terminal Solutions, Corp.
    Inventors: Akira Mori, Yuka Nishizawa

  • Patent number: 8089528
    Abstract: The color signal processing circuit includes a first calculation unit generating an R/G value, a second calculation unit generating a B/G value, and a position specifying unit specifying, based on the R/G and B/G values, a position expressed as a color temperature of the light of a light source in a color coordinate system defined by R/G and B/G coordinate axes as the position of the light source. The color signal processing circuit further includes a pull determining unit determining a displacement amount between the light source position specified and a position of a target point on a blackbody radiation curve defined in the color coordinate system, sets gain values for the R, G, B color signals for achieving a white balance based on the displacement amount, and supplies the gain values to white balance amps amplifying the R, G, B color signals, and carries out white balance processing.
