PROBLEM TO BE SOLVED: To prevent reading at a place which is not desired by an original preparing person by adding copy inhibiting information to image data at the time of detecting picture reading inhibiting information in read image data. SOLUTION: From image data reaching an area separating part 103 by way of CCD 101 and an image processing part 102, only a required image area is separate-extracted and sent to an inhibiting information judging part 121 to judge the presence/absence of a reading inhibiting image pattern in the separate-extracted image. When there is the reading inhibiting image pattern, main body control part 100 adds the bit pattern of print output inhibition in each pixel of image data to image data on an image forming part 108 with respect to an image data information adding part 122. Since the output of image data to a paper, etc., is not inhibited by image data reading inhibiting information but is regulated at the pre-stage of image data outputting by adding copying inhibiting information, the regulation of a display inhibited image is ensured. |
