光学分辨率是扫描仪最重要的性能指标之一,它直接决定了扫描仪扫描图像的清晰程度。扫描仪的分辨率通常用每英寸长度上的点数,即dpi来表示,市场上售价在1000元以下的扫描仪其光学分辨率通常为300×600dpi,而价格在1000至2000元之间的扫描仪其光学分辨率通常为600×1200dpi。另光学分辨率之外,扫描仪的包装箱上通常还会 Optical resolution is one of the most important performance indicators of a scanner, which directly determines the clarity of the scanned image. The scanner’s resolution is usually expressed in dots per inch of length, ie, dpi. Scanners priced at less than $ 1,000 on the market typically have an optical resolution of 300x600 dpi and a price of between 1000 and 2000 yuan The scanner’s optical resolution is usually 600 × 1200dpi. In addition to the optical resolution, the scanner’s box will usually be
