MATRIX VISION - mvBlueFOX3 Technical Documentation
mvBlueFOX3-1020a (1.9 Mpix [1600 x 1200])


The sensor uses a pipelined global snapshot shutter, i.e. light exposure takes place on all pixels in parallel, although subsequent readout is sequential.

Free running mode

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

                                           2             ImageHeight + 10 
ReadOutTime =  InternalLineLength * ---------------- * (-----------------)
                                    InternalADCClock          1000

If exposure time is lower than read out time:

FPS_max =  -------------

If exposure time is greater than read out time:

FPS_max =  --------------

Snapshot mode

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

                                           2             ImageHeight + 10 
ReadOutTime =  InternalLineLength * ---------------- * (-----------------)
                                    InternalADCClock          1000
FPS_max =  ----------------------------
            ReadOutTime + ExposureTime

Line scan mode

The sensor offers also a usage as a line scan sensor. One (gray scale sensor) or two lines (in terms of color sensor) can be selected to be read out of the full line height of 1600 lines. This or these lines are grouped to a pseudo frame of selectable height in the internal buffer of the camera.

The camera then outputs these frames which contain multiples of the same scan line(s) without gaps or interruptions.

To operate in line scan mode, use the following properties:

  • In "Setting -> Base -> Camera -> GenICam -> Device Control", please change the Device Scan Type to line scan.
  • In "Setting -> Base -> Camera -> GenICam -> Image Format Control", please set Width and Height. Height specifies how often the same line(s) will be used to reach the height of the image.
    Use Offset X to shift horizontally the starting point of the exposed line.
    Use and Offset Y to shift the scan line vertically.
The sensor will not get faster by windowing in x direction.
  • Finally, in "Setting -> Base -> Camera -> !GenICam -> Acquisition Control", please adapt the Exposure Time.
    The exposure time as to be low and max. approx. 60 us in order to achieve the max. line scan rate of 12.6 kHz.

You may use longer exposure times at the expense of scanning frequency.

Using more than one line e.g. 5, is like having an area scan with ImageHeight = 5. In line scan mode, the max. ImageHeight is ≤ 16.
You can use either Continuous or a trigger mode as Acquisition Mode in "Setting -> Base -> Camera -> GenICam -> Acquisition Control". However, if an external (line) trigger will have to be used, it is absolutely required that the external trigger is always present. During a trigger interruption, controlling or communication to the camera is not possible!
