Abstract
An issuing apparatus is configured to acquire an image obtained by capturing a collation image printed on an information medium via a camera as a first captured image. A collation apparatus is configured to acquire an image obtained by capturing a collation image printed on an information medium to be collated via a camera as a second captured image, generate a corrected image obtained by performing density correction on the first captured image, by predicting a density change at a time point at which the second captured image is acquired based on an elapsed time from a time point at which the first captured image is acquired, and determine a collation region for collation between the first captured image and the second captured image based on a difference image obtained by obtaining a difference between the second captured image and the corrected image for each pixel.
