早期的扫描仪定位于处理图形图象的专业领域,因而采用了传输速率比较高的SCSI接口,但也造成了扫描仪的造价偏高,不利于扫描仪的普及应用。此外,采用SCSI接口的扫描仪相对而言,在安装使用上也比较复杂。针对专业扫描仪的这些缺点,各个厂商纷纷推出了多种普及型的扫描仪。佳能公司所推出的CanoScan FB320/620彩色图像扫描仪,采用了CIS(Contact Image Sensor)技术和增强的EPP并行接口,极大地方便了扫描仪的安装、使用,并在保证扫描质量的基础上,提供了平易近人的价格。作为扫描仪,首先注重的自然是它的成像质量。CanoScan FB320/620提供了300dpi和600dpi的分辨率,并都可以达到2400dpi的插值分辨率。这两者都建立在佳能先进的LIDE技术基础之上。利
Early scanners positioned in the professional field of graphics processing, which uses a relatively high transfer rate SCSI interface, but also caused the high cost of the scanner is not conducive to the popularity of the scanner. In addition, the use of SCSI interface scanner is relatively speaking, the installation is more complicated. For these shortcomings of professional scanners, various manufacturers have introduced a variety of popular scanners. Canon’s CanoScan FB320 / 620 color image scanner, introduced by CIS (Contact Image Sensor) technology and enhanced EPP parallel interface, greatly facilitates the installation and use of the scanner, and on the basis of ensuring the scanning quality, Provides approachable price. As a scanner, the first thing to focus on is its imaging quality. CanoScan FB320 / 620 provides 300dpi and 600dpi resolution, and can reach 2400dpi interpolation resolution. Both are based on Canon’s advanced LIDE technology. Lee
