自八十年代中期第一台光电扫描仪(Scanner)诞生以来,随着计算机硬件设备资源的日新月异,图象输入-处理-输出系统不断完善,以及各类扫描仪应用系统的开发应用,光电扫描仪已逐步作为基本的输入设备成为商用和家用系统必不可少的一部分。 扫描仪的扫描过程是通过扫描光源与待扫材料之间的相对运动来完成的。按其相对运动方式的不同,扫描仪可分为平板扫描仪(Flatbed_Scanner),手持式扫描仪(HandHeld_Scanner)和滚筒式扫描仪(Scroll_Scanner)三大类。手持式扫描仪价格低廉,小巧方便,但因其对操作要求高(需手持匀速运动),精度较低等原因,只占据部分低档市场。台式平板扫描仪是目前国内应用最为广泛的扫描仪产品。它的扫描精
Since the birth of the first Scanner in the mid-1980s, with the ever-changing resources of computer hardware and equipment, the continuous improvement of image input-processing-output systems, the development and application of various scanner application systems, photoelectric scanning Instrumentation has gradually become the basic input device to become an integral part of commercial and domestic systems. The scanning process of the scanner is accomplished by scanning the relative motion between the light source and the material to be scanned. According to the relative movement of different ways, the scanner can be divided into Flatbed Scanner (Flatbed_Scanner), Handheld Scanner (HandHeld_Scanner) and Roller Scanner (Scroll_Scanner) three categories. Hand-held scanners are cheap and compact, but they only occupy part of the low-end market due to their high operating requirements (hand-held uniform motion) and low accuracy. Desktop flatbed scanner is currently the most widely used scanner products. It’s scanning fine
