4.2.2 Status Line
If enabled, the status line replaces the last row of the image with image information. It
contains the properties described above and additional information. Every parameter is coded
into 4 pixels (LSB first) and uses the lower 8 bits of the pixel value, so that the total size of a
parameter is 32 bit. The remaining pixels (24..1024) are set to 0.

The status line is also available when using an ROI. For an ROI with a width <24
pixels, the status line will be clipped.
The first two data fields of the status line (preamble and image counter) are also
transmitted on the 3D data (in either of the output modes "2D and 3D" or "3D").
Preamble:
The first parameter contains a constant value of 0x55AA00FF as a preamble in order to allow
the image processing system to easily recognise the beginning of the status line.
Image counter:
See Section 4.2.1.
Time counter:
The time counter starts at 0 after camera start, and counts real-time in units of 1 micro-second.
The time counter can be reset by the software in the SDK (Counter width 32 bit).
Missed trigger counter:
See Section 4.2.1.
Average image value:
See Section 4.2.1.
Exposure cycles:
The exposure cycles parameter outputs the current exposure time in units of clock cycles (see
Table 8.1).
