After the camera transferred a whole frame, the camera goes into wait state. When user sends an
AcquisitionStop
command in wait state, the camera will return to stop acquisition state. The camera will
not send any frames even if it is just going to start the next exposing.
8.2.2. RegionSendMode
MER-134-93U3M/C(-L) camera supports MultiROISendMode, any other cameras only support
SingleROISendMode. MultiROISendMode means the camera sends several images after one exposure
as shown in Figure 8-9
while SingleROISendMode means the camera sends only one image after one
exposure as shown in Figure 8-10

In the SingleROISendMode, the image sensor of the camera outputs only the image of the corresponding
region of the ROI.
In the MultiROISendMode, the camera will calculate the multi-ROI parameters that are set by the user and
the equivalent ROI parameters, then the image sensor will output the image of the corresponding region
of the equivalent ROI parameters.
