Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a method of embedding and detecting data for a printed image with several resolutions using a camera of a mobile phone. The proposed method is based on the method which uses the block division and code diffusion. To specify the image resolution and the number of blocks, invisible markers which are embedded in the amplitude domain of discrete Fourier transform of the target image are used. The angle between the maker and x-coordinate is used for the specification of resolution and the number of blocks. The proposed method can increase the variety of the image for data embedding. From the experimental results, it is shown that the proposed method is effective for specifying the resolution and the number of blocks in the captured image.
