SPECIFIC IMAGE AREA DETECTING DEVICE, PAPER DOCUMENT PROCESSOR, SPECIFIC IMAGE AREA DETECTING METHOD, AND PAPER DOCUMENT PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a specific image area detecting device, a paper document processor, a specific image area detecting method, and a paper document processing method with which processing costs can be reduced and processing precision is improved.;SOLUTION: An arrangement stamper is provided with a detecting part 4 for detecting a charge meter applied to a postal object. The detecting part 4 is provided with a photoelectric converting part 12 for reading the gray multi-level image of the postal object, and for reading a red bar multi-level image, a buffer 14 for storing the gray multi-level image read by the photoelectric converting part 12, a buffer 16 for storing the red bar multi-level image, and a discriminating part 18. The discriminating part 18 extracts a charge meter candidate from the gray multi-level image stored in the buffer 14, and collates it with a comparison parameter in a parameter table stored in a memory 19, and discriminates whether or not it is the charge meter.;COPYRIGHT: (C)2004,JPO&NCIPI
