    摘要: Arrangement for lifting image of checks, with Xenon lamp, Fluorescent lamp or like source of stable-wavelength-output and CCPD Camera means selected to exhibit “close-to-human” spectral response plus a photopic filter, disposed upstream of the Camera and adapted to shift its received image-light spectrum in the direction of that which is optimal for the human-eye.

    摘要: A check Sorter-Imager-Processor with two (or more) imaging sites, each lit by a beam through a fibre-optic array, with a lens focusing the beam on each array such that a shift in lens-focus reduces output light from the array, the two sites being thus "matched" in light-intensity by merely focus-adjusting these lenses.
