PROBLEM TO BE SOLVED: To provide an image processing unit that makes the estimate of the position of a specific pattern in an image difficult in order to prevent counterfeiting. SOLUTION: In the image processing that processes received data and outputs the processed data, whether data corresponding to a specific pattern are included in the received data or data resulting from processing the received data is detected, and when the specific pattern is detected, a stop means stopping the output is started. Preferably, when the specific pattern is detected, the stop means is started in random timing. Furthermore, when the specific pattern is detected, data in a storage means storing the received data are deleted. When the specific pattern is detected, an output disapproval instruction is outputted. |
