The digitization of ancient books is one of the important means to protect and inherit precious ancient books. The ancient books can be reproduced digitally through modern technologies such as scanning, which can reflect the original appearance of ancient books in a true and clear way, and provide public use through media such as the Internet. Since the 1980s, China has tried to digitize Chinese ancient books. After decades of exploration and development, it has achieved remarkable results. In 2007, the "Opinions of the General Office of the State Council on Further Strengthening the Protection of Ancient Books" was issued, which explicitly required the formulation of digital standards for ancient books, standardized the digitalization of ancient books, and established a digital resource library for ancient books. In 2011, the Ministry of Culture issued the "Notice on Further Strengthening the Protection of Ancient Books", demanding that the digitalization of ancient books be accelerated. In 2017, we will establish a more complete system and mechanism, conduct a census of ancient books, review the "National Precious Ancient Books List", improve the environment of ancient books, rescue and repair precious ancient books, and cultivate a team of ancient books, miniatures, digitization, photocopying, and interpretation of ancient books. The exhibition publicity, as well as the work of extracting historical wisdom from ancient books and providing literature basis for real work, summarizes the work of ten years of ancient books protection.
At present, the National Ancient Books Protection Center and the Provincial Ancient Books Protection Center are carrying out the construction of the Chinese ancient books digital resource library. The first stage is to start with the “National Precious Ancient Books Directory†and complete the 10,000 kinds of national precious ancient books directory data and images within 5 years. Database construction work. According to reports, there are still some shortcomings in the digital construction of ancient books in China. For example, lack of unified planning, serious construction, lack of unified standards, hinder resource sharing, lack of financial support, uneven regional development, and no unified publishing platform, which is not conducive to user inquiries. The meeting put forward specific suggestions for the standardization of the digitalization of ancient books, in order to realize the requirements of unified planning, unified standards, cooperation and construction, and resource sharing of digitalization of ancient books.
The process of documenting from paper to digital is basically done using a CCD scanner. The paper medium is imaged by a CCD through a certain optical path and captured to form a discrete digital signal - an electronic image. In order to save storage space, electronic images are compressed in different compression methods and saved as disk files with a fixed format. In addition, in the process of digitizing paper files, there will be differences in the format and binding form of the paper. Usually file files, vouchers, books, etc. are bound in the form of this book, and the drawings are characterized by large format. Therefore, in the process of digitization, it is necessary to carry out specific analysis for different paper file characteristics, and select suitable ones. The scanner can only do digital work, otherwise it will be half the effort.
