扫描仪扫描效果的好坏取决于扫描速度、分辨率、色彩等等。只要你在选购时了解清楚这些指标并亲身试用,就可避免买到假冒伪劣产品。市面上的扫描仪其光学分辨率通常有300×600dpi、600×1200dpi两种,虽然对于一般用户来说300×600dpi的光学分辨率就够用了,但是如果在价格差不多的情况下最好选600×1200dpi。另外,除了光学分辨率之外,扫描仪的包装箱上还会标注一个最大分辨率,如光学分辨率为600×1200dpi的则为9600dpi,实际上这是通过软件在真实的像素点之间插入经过计算得出的额外像素,从而获得的插值分辨率。插值分
Scanner scan quality depends on the scanning speed, resolution, color and so on. As long as you understand these indicators in the purchase and try it yourself, you can avoid buying fake and shoddy products. Optical scanner on the market usually have 300 × 600dpi optical resolution, 600 × 1200dpi two, although for the average user 300 × 600dpi optical resolution is enough, but if the price is similar in the case of the best choice 600 × 1200dpi. In addition, in addition to the optical resolution, the scanner’s box will be marked with a maximum resolution, such as the optical resolution of 600 × 1200dpi then 9600dpi, in fact, this is inserted between the real pixels through the software Calculated extra pixels, resulting in interpolation resolution.
