<p>The present invention relates to a method for detecting a forged card including a control unit (310), a display unit (350) which displays an image by a control command from the control unit (310) to be connected to the control unit (310), a storing unit (330) which is connected to the control unit (310) and stores a forged card detection program, and an input unit (350) which is connected to the control unit (310) and inputs a command. The present invention includes a data image extracting step (ST-200) composing an average image extracting step (ST-210) which generates and stores an average image by an operation for a pixel forming a plurality of individual card images and a differential image extracting step (ST-220) which generates and stores a differential image by the operation for the pixel forming the average image.</p> |
