德国爱莎ESSER噪声测试卡TE270X详细介绍
The TE270X chart is similar to the TE264 but it is equipped with two polarizing filters in the center of the chart. For cameras that do not allow a manual adjustment of the exposure, the automatic exposure control (AEC) is fooled by modifying the density (transmission) of the central part of the test chart.
This feature is needed especially for low-end cameras and camera modules in mobile devices that often do not have a manual exposure adjustment.

对于低端相机和移动设备的相机模块特别需要此功能，主要是应为其没有一个手动曝光调整
