PURPOSE: To judge the imitation or real of the sheet immediately by containing a normal portrait and split images of the portrait in the sheet and reproducing the portrait from the split one to compare with the normal one. CONSTITUTION: A portrait 18 is captured in the TV camera 20 and the image signals are digitized and transmitted to the image composer 22 and computer 23. The computer 23 processes the signals to split plural sections and changes the order according to a specified rule. The changed signals are converted and outputted to the image composer 22. When the sheet is judged its reality, the normal portrait 1a on the sheet and reproduced image 1d from the computer 23 are displayed on the color monitor 28 simultaneously to compare whether they are matched or not. |
