4 Functionality
Skimming is not supported in simultaneous readout mode.
4.1.4 Constant Frame Rate (CFR)
When the CFR mode is switched on, the frame rate (number of frames per second) can be
varied from almost 0 up to the maximum frame rate. Thus, fewer images can be acquired than
would otherwise be possible.
When Constant Frame Rate is switched off, the camera delivers images as fast as possible,
depending on the exposure time and the read-out time. See Section 5.3.2 for more
information.
Constant Frame Rate mode (CFR) is not available together with external trigger
mode.
4.2 Image Information
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.
4.2.1 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.
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).
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.
