MATRIX VISION - mvBlueFOX3 Technical Documentation
mvBlueFOX3-1012d (1.2 Mpix [1280 x 960])

Introduction

The sensor features one acquisition mode:

  • rolling shutter.

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

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 * (    1650    )) + ((VerticalBlank+2) *      1650    )
FrameTime =                 ------------                           ------------
                             PixelClock                             PixelClock

If exposure time is lower than frame time:

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

If exposure time is greater than frame time:

                1000000
FPS_max =   ----------------
               ExposureTime

Snapshot mode

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

            (ImageHeight * (    1650    )) + ((VerticalBlank+2) *      1650    )
FrameTime =                 ------------                           ------------
                             PixelClock                             PixelClock
FPS_max =                  1
           -----------------------------------
                 FrameTime + ExposureTime

Note
The exposure time step width is limited to the sensor's row time of 41.3 us and therefore
- auto exposure with very low exposure times will perform with relatively large increments and
- exposure mode = TriggerWidth (if available) will perform with a jitter corresponding to the row time
