| | GLOBAL | In global shutter readout mode the entire detector integrates over the same time period. Global shutter images will have higher noise relative to rolling shutter images, but no spatial distortion beyond that caused by the optics (less than or equal to 0.1%). |
| | ROLLING | In rolling shutter mode each row of the detector integrates over the same amount of time, but the exact moment in time captured by each line is different (i.e., each line begins integrating by one line time after the previous line). |
