摘要

The invention discloses an apparatus for filing and printing data available for individual identification, which characterisitically comprises the following, an image data base memory which stores plural pieces of facial photographic data available for individual identification in the form of multi-gradational image data, a means for delivering data read out from the image data base memory in the form of printable data available for a multi-gradational video printer capable of modulating gray level per picture element, a means for generating pseudo multi-gradational bilevel data by arithmetically processing image data read out of the image data base memory by applying pseudo multi-gray scale modification, and a bilevel recording printer which receives the generated pseudo multi-gradational bilevel data and than prints the pseudo multi-gradational bilevel image.
