The image processing system includes a processing unit for correcting an image input unit for generating electronic data representing the image by reading an image printed on a medium, an image represented in the electronic data. The processing unit from the represented image into electronic data, a function of detecting a first pattern having a first size and shape that is attached to the image, the size of the first pattern is detected, the realizing a function of measuring the amount of deviation from a size as deterioration degree, a function of correcting the image represented in the electronic data so that the deterioration degree becomes small.
