<p>The present invention provides a discrimination method which reduces memory size and validate bills at a high speed. Accoding to the present invention, reflected light or transmitted light from a paper note is received by an image sensor, image data is stored in a memory device, a region of the paper note is cut out from the image data in the memory device, the cut-out paper note image data is blocked and normalized, and a bit corresponding to the blocked value is turned on, the block paper note image data is encoded into pattern data, and the compression-coded pattern data is compared with prestored reference paper note pattern data to discriminate the paper note. <IMAGE></p> |
