摘要
本文按照ISO 12233标准建议的倾斜边缘法测量了两款消费级平板扫描仪的空间频率响应。测量结果表明,扫描仪的实际分辨率明显低于制造商给出的数据,且提高扫描分辨率并不能改善扫描仪的空间频率响应,这种特点值得使用者注意。
In this paper,Spatial frequency respanse（SFR） features of two types of consumer flatbed scanner were measured with the slanted-edge method acconding to ISO 12233.The results show that the actual resolution of two scanners is significantly lower than the datas given by scanner manufacturers,and the SFR features of scanners can not be improved by increasing scanning resolution,which is worthy of notice by scanner users.
