Collating device of seal impression

Abstract

Abstract PURPOSE:To collate a seal impression surely by synthesizing a combinational picture on the screen of a CRT on a basis of picture data of the seal impression to be collated and a reference seal impression and each partition set data. CONSTITUTION:The seal impression to be collated is converted to a picture by a camera device 5 and is sent to a picture memory 10 of a picture processing device 7. The reference seal impression picture stored in an external memory 6 is sent to the memory 10 also. Data of both pictures are taken into the memory 10, and data are read out from the memory 10 by a CPU12 and are sent to a display circuit 18. The reference seal impression and the seal impression to be collated are displayed on both sides of partitions having a certain angle and the combinational picture which is formed by overlapping of both seal impressions is displayed on the inside of them on the screen of a CRT18. Further, the inked part of the reference seal impression, the inked part of the seal impression to be collated, their background parts, and the overlapped seal impression part are displayed in red, blue, white, and purple respectively, and the inclination of partitions is changed by the operation of a keyboard 23.
