Image forming apparatus

摘要

An image forming apparatus includes a character distinguishing unit, a character string extraction unit, a character specifying unit, a determination unit, an overwrite image data generation unit, and a control unit. The overwrite image data generation unit generates, if it is determined by the determination unit that there is a plurality of matches, overwrite image data that has been overwritten such that a character specified by the character specifying unit is indistinguishable as a character. The control unit performs control using the overwrite image data generated by the overwrite image data generation unit so as to cause a printing unit to perform printing on a printed material set in a printed material setting unit.

1. An image forming apparatus comprising:
a printed material setter configured to cause a user to set a printed material on which a character is printed therein; a printer configured to perform printing on the printed material set in the printed material setter; a printed material image reader configured to read an image printed on the printed material set in the printed material setter; a character distinguisher configured to distinguish a character from the image read by the printed material image reader; a character string extractor configured to extract a character string formed of a plurality of characters distinguished by the character distinguisher; a character specifier configured to cause the user to specify one of the plurality of characters forming the character string extracted by the character string extractor; a determiner configured to determine whether or not there is a plurality of matches between character string data formed of a part of the extracted character string other than the character specified by the character specifier and respective parts of character string data registered in dictionary data in which a plurality of character strings each of which is formed of a plurality of characters are registered in advance, each of which is formed of characters other than a character in the same position as a sequence position of the character specified by the character specifier; an overwrite image data generator configured to
generate, if the determiner determines that there is a plurality of matches, overwrite image data that has been overwritten such that the character specified by the character specifier is indistinguishable as a character, andif the determiner does not determine that there is a plurality of matches, not to generate the overwrite image data; and a controller configured to perform control using the overwrite image data generated by the overwrite image data generator so as to cause the printer to perform printing on the printed material set in the printed material setter.
