作为一种不可或缺的输入设备,扫描仪得到了越来越多的关注。但扫描仪所使用的一些技术和某些常用的性能指标对于普通用户来说较难理解,往往会增加用户选购产品和使用产品的难度。我们力争用最容易理解的方式,最简单的语言解释一些专业名词,以帮助读者增加对扫描仪的了解。 CCD扫描仪 CCD扫描仪的工作方式有些类似于复印机的工作原理,它是由传动装置驱动一系列透镜和镜面组成的光学系统和CCD(电荷耦合器件)半导体芯片来完成扫描操作。CCD技术是目前大多数平板扫描仪所采用的技术,它能够获得完美的图像质量,但精密的光学系统使机器体积庞大。 CIS扫描仪 CIS(Contact Image Sensor)扫描仪用光敏传感器代替了复杂的光学系统,使扫描仪体积大大减小,厚度减到只有
As an indispensable input device, scanners get more and more attention. However, some of the techniques used by the scanner and some commonly used performance metrics are more difficult for the average user to understand and tend to increase the difficulty of users purchasing and using the product. We strive to use the most easy to understand way, the most simple language to explain some of the professional terms to help readers increase the understanding of the scanner. CCD Scanners CCD scanners work somewhat similarly to photocopiers and are driven by a series of optical and CCD (Charge Coupled Device) semiconductor chips that drive a series of lenses and mirrors to perform the scanning operation. CCD technology is currently used by most flatbed scanners, which can achieve perfect image quality, but the sophisticated optical system makes the machine bulky. CIS Scanner CIS (Contact Image Sensor) scanner with a photosensitive sensor instead of a complex optical system, the scanner size is greatly reduced, the thickness reduced to only
