9.3.2.4 mvBlueLYNX-X105 (5MP 2592 x 1944)
This sensor uses two acquisition modes:
rolling shutter (ShutterMode =
ElectronicRollingShutter
) and •
global reset release shutter (ShutterMode =
GlobalResetRelease
). •
With the rolling shutter the lines are exposed for the same duration, but at a slightly different point in time:

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:

This means, the bottom lines of the sensor will be exposured longer! For this reason, this mode will
only make sense, if there is no extraneous light and the flash duration is shorter or equal to the exposure
time.
Global reset release will only make sense, if a flash is used which is brighter than the ambient light. The
settings in wxPropView will look like this:
