| 摘 要： | 基于CCD和CMOS传感器技术的数字照相机迅速地占领了市场，与平板扫描仪一起，成为印刷工业最重要的数字图像转换设备，还能够直接拍摄场景。数字照相机几乎与色彩管理技术同步发展，由于色彩管理技术在彩色复制工作流程中的地位越来越重要，导致在究竟应该采用RAW数据以及应该使用sRGB色彩空间还是Adobe RGB（1998）色彩空间上产生了许多争议，这些争议归结为数字照相机应如何捕获图像数据。

| Abstract: | In this paper,definitions of spatial frequency response and modulation transfer function were given.Accordingly,some important concepts and relationship between SFR/MTF and resolution or sharpness related to both of them were introduced.Additionally,cumulative effects of MTF were also discussed,and addressed aspect was MTF measurement method based on captured image data according to ISO 12233 international standard. |
