Abstract

PURPOSE:To attain the objective collation of seal impressions in an easy and quick way by displaying a reference seal print and a seal print to be collated with superposition on each other together with the superposition factor and the density ratio displayed on a screen as the parameters for decision of a collation factor. CONSTITUTION:A reference seal print and a seal print to be collated are displayed with superposition on each other. At the same time, both the superposition factor and density ratio between both seal prints are displayed quantitatively. Thus an AND total bit calculating circuit obtains the total bit number C with which the information on both seal prints are equal to 1 on the same picture element for each same address. The total bit numbers B and A of the data 1 are counted by both total bit calculating circuits for reference seal print and seal print to be collated. Then a CPU performs a prescribed operation to obtain both the superposition factor and density ratio. These factor and ratio can be displayed in percentages on a color CRT, by means of a character display controller.
