Abstract

An arrangement for lifting images of check documents at one or more check-imaging stations; each station being illuminated and providing an image-lift optical pathway to an electronic camera, this image pathway including photopic filter means adapted to shift the received spectrum in the direction of optimal human-eye response; the camera being selected and operated to exhibit a spectral response close to that of the human eye.
