Abstract
A document image to be corrected is read out from an image file which stores document images, converted into dots, and printed on a correction paper. An operator writes correction information on the correction paper which is in turn inputted to the image file system with an image reader. The image file system erases the dot image information of the image inputted with the image reader. The obtained correction information is synthesized with the original image read out from the image file. The synthesized corrected image is stored in the image file.
