Outline of Final Research Achievements

We developed the research on the technique of embedding information in the captured image of the real object by illuminating it with brightness-modulate light. The main results are as follows. We enhanced robustness of information hiding by embedding same information in many different positions, and we developed the technique that can apply this concept to moving picture using temporally luminance-modulated light. Moreover, we developed the technique that can hide information on depth of the object in its captured image using the light that contains invisible pattern of which characteristics depend on depth.
