Abstract

PURPOSE: To make it possible to verify prints of seals stamped overlapping each other by obtaining digital seal-print patterns of different kinds of color information and then by collating those with registered patterns.
CONSTITUTION: Color picture input unit 9 reads color information on a subject to obtain three analog signals, which are logarithmically converted 10 and conversion outputs are weighted by matrix arithmetic circuit 11 to obtain two analog signals. Those analog signals are in proportion to the density of the seal prints stamped overlapping each other and each signal is supplied to digital circuit 2, which converts it into a digital picture, so that they will be stored in memory 3. Those digital pictures are collated with prints of seals stored in memory 4 to verify the seal prints stamped overlapping each other.
