1. Linear non-contact CCD scanning method: At present, mainstream scanners mainly use two scanning methods: 1) linear CCD scanning; 2) matrix scanning (commonly known as surface scanning). The main difference between the two scanning methods is that linear CCD scanning is performed by progressive scanning. Scanning, the details and clarity of the image are consistent, but the scanning speed is relatively slow; the matrix CCD scan speed is fast, usually the scanning time is one-fifth of that of the linear CCD scanner, but the scanning image has poor definition and serious deformation. For CCD scanning, which requires very high definition, linear CCD scanning technology is undoubtedly the first choice. 2. Under the premise of ensuring image quality, the scanning efficiency is high: At present, the number of devices in the linear CCD scanning technology, under the premise of effectively guaranteeing the scanning quality, the scanning speed is the fastest. 3, support ICC Profile full color management The ICC Profile is simply a description of the color characteristics of a color device. It shows the correspondence between the color description of this particular device and the standard color space. Therefore, the input and output of the image are better kept consistent, and the input and output devices maintain a consistent color standard, which provides strong support for post-image printout and simulation copying. 4, automatic white balance function The automatic white balance setting ensures that the series of scanners has an automatic white balance function, so that there is no chromatic aberration in the image obtained by each scan. At present, many scanning devices of the same type on the market do not have an automatic white balance function, resulting in a large color deviation of images obtained after two scans. 5, using local light focusing illumination Many devices on the market rely on ambient light without relying on ambient light, resulting in uneven image exposure. It is extremely difficult to do image processing in the later stage. The OS12000 series scanners all have LED light source, long life, zero light decay, and uniform light intensity. Minimize the contamination of the scanning environment by the external light source, so as to ensure the uniformity of the overall light of the image during the scanning process. 6, semi-automatic glass press device The semi-automatic glass press device can ensure the maximum protection of the file roll from external force during scanning, and the foot switch and exposure switch equipped at the same time can minimize the workload of the staff. 7, from the back to the front of the scanning method The scanning method from the back to the front ensures that the scanner does not exhibit its own light pollution during the scanning process. At present, some book scanners on the market adopt a left-to-right scanning mode, which inevitably causes the light source to interfere with the scanning head due to refraction when the two side light sources are irradiated to the center position. 8, unique dual scanning head technology For the ancient books, the biggest feature is the irregularity of the size. The game number scanner uses a dual scanning head technology combining stereo and plane to superimpose the stereo image and the planar image, and then correct the deviation and correct the middle seam through the Perfectbook function. 9, the professionalism of the equipment: A special scanner equipped with a V-type platen has been developed for ancient books that cannot be fully opened. The platen can not only change the width of the middle seam, but also scan the ancient books at any angle between 90-135 degrees, and at the same time ensure the scanning quality of ancient books. It is also equipped with a corresponding glass press device. 10. Connection method: IEEE1394 image acquisition card is widely used in image acquisition, especially in non-linear editing with high image requirements. It is obviously higher than SCSI in transmission speed, equivalent to the average transmission rate of usb2.0; stability is obvious Better than USB and TCP/IP interface devices, there will be no problems such as packet loss. Due to the high precision requirements in the digital work of ancient books, the images generated after scanning are large, so the use of the IEEE 1394 card does not cause abnormal phenomena such as packet loss.
