The following Pearleye P-030 LWIR table shows an overview of the consumed
time by the command k=0:
T = Time for one frame-out (Pearleye P-030 LWIR: 41.6 ms)
N1 = number of data sets (max. 32)
N2 = number of integrated images (max. 64)
In case that the camera is exposed to unsteady operating conditions it might be
an advantage that the automatic data set selection regularly starts on its own.
If k is not set to 0 the automatic search starts at approx. each k * 256
images. At a frame rate of e.g. 40 images per second the chronological resolu-
tion of the k value is approx. 6.4 seconds.
Example
The automatic correction data selection shall always be started approx. every
1200 seconds (20 minutes): 1200 sec. / 6.4 sec. per count ≈ 188 = 0xBC.
