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)
If the camera is exposed to unsteady operating conditions it might be an advan-
tage 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 resolution 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.
