Introduction

The sensor features several acquisition modes ("mv Shutter Mode"):

rolling shutter ("mvRollingShutter").

Note: "FrameStart" is not available in "Settings → Base → Camera → GenICam → Acquisition Control → Trigger Selector"

With the rolling shutter the lines are exposed for the same duration, but at a slightly different point in time:

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.

Free running mode

To calculate the maximum frames per second (FPS_max) in free running mode you will need following formula:

            (ImageHeight * (    2176    )) + (VerticalBlank *      2176    )
FrameTime =                 ------------                       ------------

                1000000
FPS_max =   ----------------
               FrameTime

Snapshot mode

To calculate the maximum frames per second (FPS_max) in snapshot mode you will need following formula:

            (ImageHeight * (    2176    )) + (VerticalBlank *      2176    )
FrameTime =                 ------------                       ------------
