Figure 1: Rolling shutter
In rolling shutter mode, a doubling of the exposure time clearly leads to a doubling of the gray
value:
ExposureTime2
GrayValueFactor = -------------
ExposureTime1
Note:
Moving objects together with a rolling shutter can cause a shear in moving objects.
The global reset release shutter, which is only available in triggered operation, starts the exposure
of all rows simultaneously and the reset to each row is released simultaneously, too. However, the
readout of the lines is equal to the readout of the rolling shutter: line by line:
Figure 2: Global reset reslease shutter
Note:
The max. exposure time of the global reset release mode is 206ms.
Any triggered operation (like software trigger) leads inevitably to the global reset mode (even if the
shutter mode property is still set to "mvRollingShutter").
