Image Information and Status Line
There are camera properties available that give information about the acquired images, such
as an image counter, average image value and the number of missed trigger signals. These
properties can be queried by software. Alternatively, a status line within the image data can be
switched on that contains all the available image information.
4.11.1
Counters and Average Value
Image counter
The image counter provides a sequential number of every image that is output.
After camera startup, the counter counts up from 0 (counter width 24 bit). The counter
can be reset by the camera control software.
Real 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
The missed trigger counter counts trigger pulses that were ignored by
the camera because they occurred within the exposure or read-out time of an image. In
free-running mode it counts all incoming external triggers (counter width 8 bit / no wrap
around).
Missed burst trigger counter
The missed burst trigger counter counts trigger pulses that were
ignored by the camera in the burst trigger mode because they occurred while the camera
still was processing the current burst trigger sequence.
Average image value
The average image value gives the average of an image in 12 bit format
(0 .. 4095 DN), regardless of the currently used grey level resolution.
4.11.2
Status Line
If enabled, the status line replaces the last row of the image with camera status information.
Every parameter is coded into fields of 4 pixels (LSB first) and uses the lower 8 bits of the pixel
value, so that the total size of a parameter field is 32 bit (see Fig. 4.53). The assignment of the
parameters to the fields is listed in Table 4.8.
The status line is available in all camera modes.
