PURPOSE:To execute a forgery judgement processing for preventing forgery to whole picture outputs in a color workstation. CONSTITUTION:A reader part 11, a printer part 13 and a hostcomputer 18 are connected in the workstation. The hostcomputer 18 stores color picture data which is read by the reader part 11 in a picture memory 15 and a forgery judging part 14 compares and collates color picture data stored in the picture memory 15 with previously prepared plural different picture patterns. When collated result as coincidence is obtained, color picture data stored in the picture memory 15 is outputted to the printer part 13 as it is and color picture data stored in the picture memory 15 is worked and outputted to the printer part 13 at the time of obtaining collated result as non-coincidence. |
