IMAGE PROCESSOR, IMAGE PROCESSING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent the capture of an image.SOLUTION: A two-dimensional code (2) with a logo displayed in a display part is regularly changed such that the background image (23) thereof is partially or entirely difficult to be recognized with naked eyes. Since the background image (23) of the two-dimensional code (2) with a log is prevented from partially changing in a screen shot (still image) generated by capturing such a two-dimensional code (2) with a log, it is possible to easily determine that the screen shot is not true. Thus, it is possible to prevent the two-dimensional code (2) with a log from being captured.
