Abstract (in Japanese) (See Japanese page) 
(in English) Recently, various utilizations of digital-camera have been spreading with popularization of cell-phones and smart-phones.These digital-cameras are used not only for photographing, but also for an interactive tool between a real world and virtual world.Though, bar-codes or QR-codes are well-known examples of such tools, there exist strict limitations for its design and space allocation.In order to realize various application, researchers propose some methods which embed information to image directly in the imperceptible format. However, the practical use is difficult because of serious distortion by photographing.
In this paper, we propose an embedding method that corrects photographing distortion. The method is realized by combining the noise tolerant embedding algorithm with the compensation algorithm after photographing.
