| Abstract(in English) | These days, reading on an electronic display device such as a tablet computer is popular. One of the typical document formats, the PDF is also used for printing prepress work flows and standardized as PDF/X-1a. This application requires quality of contents, and the highest-quality materials consisting contents pages need to be packed in a PDF. Whereas, electronic browsing applications consider transmission costs and performances of display devices, and storage size of created PDF must be somewhat limited. For this reason, a PDF for electronic browsing is likely to be created by simply sub-sampling a PDF file made for prepress works. This causes a novel problem of readability of bitmap-type letters in inserted pictures or drawings, which has not been occurred in the conventional printed media. In this paper, we propose a novel compression and optimization technique of PDF files for electronic display devices, maintaining as similar readability as that of printed media. Moreover, we propose an information hiding technique for PDF files, by which we can layout both text and image data invisibly and extract these hided data with a generally used PDF reader tool. |
