1. A method of image processing comprising the steps of:
receiving image data of an original image, the original image having character images provided on a background image;
conducting character recognition on the image data including
preprocessing the image data for character recognition;
extracting areas from the image data which correspond to the character images; and
generating character code data based on the extracted character images;
changing, based on the character recognition, the image data by replacing the extracted areas with the background image with
reference to the image data therein generating changed image data representing an image which is same as the original image
except without the character images; and
storing the changed image data and the character code data along with a relationship between them.
