Abstract(in English) | There are carrier screen images which used as document security such as anti-counterfeiting technology for the bank notes. The secret information is visualized by overlaying matching screens or scanning with a certain frequency band. Also it can be decoded using a digital camera. In this study, we propose a carrier screen image for decoding with an ordinary compact digital camera. In particular, an experiment with a line pattern test chart is conducted to test the angular selectivity of the sampling process of a digital camera. |
