Abstract
Disclosed is a banknote processing method and device. The banknote processing method includes: scanning a substrate through the image acquisition module while acquiring banknote image data through an image acquisition module to obtain substrate image data; acquiring a characteristic value of the substrate image data; calculating a change value of the characteristic value of the substrate image data relative to a reference characteristic value; judging whether the change value is greater than a preset threshold value; and configuring parameters of the image acquisition module if it is judged that the change value is greater than the threshold value.
