Abstract

PURPOSE:To improve the decision accuracy of a seal print collation, and also, to use an inexpensive display by setting the density of seal print information to a value being suitable for a display resolution of a display. CONSTITUTION:A marker which is generated by a marker generating mover 5 is moved to a registration and a seal print to be collated 11 which are displayed to an actual size, respectively, a seal print feature point of almost the same part of both seal prints is extracted arbitrarily, and enlarged and displayed to match a resolution of a CRT display 7. By enlarging the seal print information to match the resolution of the CRT display 7, a feature point of a boundary of a seal print dot part, or a detailed part becomes distinct, and also, a dot separation due to an excessive enlargement is avoided. In this regard, by selecting an enlarge part by the marker, an image processing of a rotation, a movement, etc., having a high level and generating a processing error is not required. In such a way, a comparatively inexpensive CRT display can be used, and also, the decision accuracy is improved.
