扫描仪是继键盘、鼠标之后的第三代电脑输入设备。这种综合了光、电、机械等学科领域的产品,自1984年诞生以来,经历了黑白、灰度、彩色三个阶段。产品类型也由较简单的手持扫描仪,发展为台式扫描仪、手持扫描仪、大幅面工程图纸扫描仪和馈纸式扫描仪等多种。扫描仪的优点是将图片、文字、表格等通过扫描输入电脑,再通过相应的软件对其进行各种编辑操作。它不但摆脱手工键盘的单字键输入和重复录入,而且大大提高了资料在传输过程中的信息保真度,因此应用范围逐渐由条码识别、图形图像处理发展到图文数据库、广告美术设计、多媒体图文通信和电脑传真等各个领域。扫描仪市场总量概述总体来说,中国扫描仪市场尚处于初级开发阶段。其特点是各厂商产品定位尚不明确;用户使用扫描仪的需求并未上升到主导地位;PC机和扫描仪的配套率不足4％,远远低于国际上公认的15％的配套标准,因此我们试图从1996～1997年度的扫描仪的销售总量、各类型的扫描仪的分布、用户的需求调查和扫描仪的配套率等四个方面对中国扫描仪市场总量进
The scanner is the third-generation computer input device following the keyboard and mouse. This product, which integrates optical, electrical and mechanical fields, has experienced three stages of black and white, grayscale and color since it was born in 1984. Product types have also evolved from simpler hand-held scanners to desktop scanners, hand-held scanners, large format engineering scanners, and sheet-fed scanners. The advantage of the scanner is that the pictures, texts, forms, etc. are scanned into the computer and then various editing operations are performed through the corresponding software. It not only gets rid of the single-key input and duplicate entry of the manual keyboard, but also greatly improves the information fidelity of the data in the transmission process. Therefore, the application scope gradually evolves from bar code recognition, graphic image processing to graphic database, advertisement art design, and multimedia. Graphic communication and computer fax and other fields. Overview of the total scanner market In general, the Chinese scanner market is still in the initial development stage. Its characteristic is that the positioning of various manufacturers’ products is not yet clear; the demand for users to use scanners has not risen to a dominant position; the matching rate for PCs and scanners is less than 4%, far lower than the internationally recognized 15% supporting standard. Therefore, we attempted to increase the total market for scanners in China from the total sales volume of scanners in 1996-1997, the distribution of scanners of various types, the survey of user needs, and the matching ratio of scanners.
