SensorShutterMode – Enum – R/W
Type of the shutter. Figure 1 illustrates different sensor shutter modes.
Global [Default] All pixels reset and start exposure at same time.
All pixels shifted to readout at same time. All pixels have
same ExposureValue
Rolling Each row is reset, exposed, and read out in succession
from top to bottom of image. All pixels have same
ExposureValue. This mode is susceptible to motion blur;
however, this mode offers enhanced SNR/dynamic range
GlobalReset All pixels reset and start exposure at same time. Pixels are
shifted to readout one line at a time from top to bottom of
image. This mode does not allow overlapped exposure and
readout. In this mode, ExposureValue is the time from
global reset to start of readout of top row. Subsequent
rows will have a longer exposure time (ExposureValue +
row readout time * row number). This mode offers
enhanced SNR/dynamic range with no motion blur, which
is useful for strobe applications
