Imatest Master(2021版)

matest master是完全功能的软件，即可用于检测数字相机、摄像机、工业相机拍摄的图像质量，也可用于交流检测结果。其功能包括：

• SFRplus：可以与SFRplus测试卡配合使用，检测MTF,横向色差，畸变，阶调响应和颜色还原。
• SFR：配合测试卡，可检测相机和镜头的锐度，噪音，色差。可以在相对条件下比较不同相机的表现。比较的最小区域可达10X10个像素。
• MTF：使用SFR的结果比较不同相机、镜头和影像系统的MTF性能。
• Stepchart：配合灰阶测试卡检测相机的阶调响应，噪音，动态范围。还可用于检测曝光的准确性，镜头眩光。
• Distortion：检测镜头的畸变，使用可打印的正方形和矩形网格计算矫正系数。
• Uniformity：检测镜头的渐晕，检测多种图像传感器的不均匀性，包括色彩阴影，具体的噪音分部，可见的不均匀性，灰尘污点。标识出有问题的像素。 显示选项包括迭生在图像上的轮廓线，或伪彩色的色条。
• Test Charts：可以生成图像文件用打于打印测试图。生成的测试卡包括SFR斜边图像，星形测试图，各种频率和反差的图样。可选项包括：反差，高光色彩，正弦线和条纹模式。可输出位图或 可绽放矢量图 (SVG).
• Print：打印检测，可以检测打印机、纸张、墨水的质量，包括色彩响应，色域，阶调响应，最大密度，ICC描述文件和呈色意图。
