With the improvement of domestic digital construction, the widespread use of paperless office and electronic information, more and more paper documents need to be converted into electronic files for transmission and utilization on the network. One of the main businesses of China International Book Trade Corporation is to sell various books, magazines, newspapers, etc. to major libraries overseas. These books and newspapers are mostly sold in the form of original book paper. It is more intuitive, but it also has the following shortcomings:
1. The weight of the original of the newspapers and periodicals increases the operating cost and the mailing time is too long;
2. Older books and newspapers will be damaged during transportation;
3. For precious books, once the newspapers are lost, they will cause huge losses;
4. For some books that are more precious and can no longer be published, it is difficult to find them after the sale, and the demand for digital books by foreign customers is further increased.
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 accounting files, especially the vouchers and ledgers, are bound in the form of this book, and the drawings are characterized by large format. Therefore, in the process of digitization, specific analysis of different paper file characteristics is needed. If you choose the right scanner, you can do the digital work, otherwise it will be half the effort.
At present, scanners can be roughly divided into four categories: high-speed scanners, book scanners, flatbed scanners, and wide-format scanners. The high-speed scanner features an automatic feeder that automatically flicks paper for high-speed scanning. For example, the KODAK I series, from 20 to 100 pages per minute, holds the high-end scanner high-end market and has many The perfect image scanning technology of patented technology.
