摘要	In order to avoid image degradation caused by rolling shutter distortion, CMOS imager sensors (CISs) with global shutter (GS) function are required to capture a picture of the fast moving scene. However, due to parasitic signal generated at the storage node of the GS CIS, the output of the sensor is degraded, which causes the sensor output varying hugely at the same exposure time but different frame rate. Then, the exclusive relationship between radiation intensity and sensor output cannot be obtained through radiometric calibration. The traditional approach is adding the light-shield structure for the storage node. We present here a new variable operation mode of the GS CIS, which makes it possible to automatically adjust the sequence of the sensor operating state on the basis of the relationship between exposure time and frame rate. This operation mode can ensure that the integrity of the stored signal is not compromised during the memory period. The accuracy of detection can be well improved. Furthermore, this new approach is proved valid by comparing the radiometric calibration results of traditional and new operation modes.
