Since public libraries want to play a role in promoting and leading the reading of the public, they should be at the forefront of the times, comply with this change in people's reading methods, and strive to promote the digital development of public libraries.
The latest generation of book scanners with projection-type dazzling cold light source technology are suitable for all books, files, maps and various drawings that need to be scanned. The low-brightness light source provides extremely sufficient protection for precious books and archives, and the high-precision true color scanning lens perfectly reproduces the true details of the original. For precious documents that cannot be disassembled, or all kinds of drawings and pictures in A2 format, book scanners should be used to scan. Such scanners can fully solve the black stitches and fonts generated when scanning documents that cannot be disassembled. The problem of deformation.
1. CCD linear scanning, electronically controlled scanning system instead of shutter design. Electronically controlled linear scanning system is fully electronically controlled and has no life limit. The light source and CCD move synchronously from the front to the direction of the scanner to ensure uniform illumination of the scanning surface, no shadows will be produced even in the middle of the book, and uniform color image quality can be obtained without being affected by external light;
2. The number of OS12000 book scanners is equipped with powerful scanning software and image processing software, which supports the embedding of ICC feature files, which can meet various needs of users. The powerful work management module function facilitates users to batch process various book scanning tasks. The image of any part of the book can be customized, and 10 images in different positions in writing can be obtained in one scan, such as newspaper clippings, which can also meet the specific needs of users; the randomly configured PerfectBook perfect 3D book scanning module is currently the only professional book scanner Using two imaging system scanners, a linear CCD to obtain a plane image of the scanning surface, and a 3D camera to obtain a three-dimensional image of a book. The hardware superimposes the two images, which is very convenient for automatic correction, distortion correction of characters and lines on both sides of the middle seam, Automatic spine curvature correction, automatic recognition of book outlines, automatic paging and automatic removal of finger images. The specific scanning method is shown below:
3. 80% market share of domestic high-end professional ancient book scanners; the global market share can reach 70%.
4. The after-sales engineers are all strictly trained and certified by the manufacturers. Beijing, Shanghai, and Guangzhou have engineers and parts libraries, which can quickly solve the worries of users.
