MATRIX VISION - mvBlueFOX3 Technical Documentation
mvBlueFOX3-1031 (3.2 Mpix [2048 x 1536])

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 (FPSmax) in free running mode you will need following formula:

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

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

Snapshot mode

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

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