Long Exposure Compensation (A504K/Kc, A503K Only) - Basler WOOD BURNING FIREPLACE Wood Burning Fireplace

Basic Operation and Features
3.4 Long Exposure Compensation (A504k/kc, A503k
Only)
The long exposure compensati-
on value can be set to optimize
image quality. The longer the
exposure time, the higher the
long exposure compensation
needs to be. The long exposure
compensation value determines
the reset voltage which is
applied to the pixels between
two images to achieve full and
uniform discharge.
If the long exposure compen-
sation is too low at a long expo-
sure time, the image shows
photo response non-uniformity
(PRNU).
If the long exposure compensa-
tion is too high at a short exposure time, the dynamic range and the sensitivity are reduced.
Set the long exposure compensation manually according to the following formula or according to
Table 3-1:
1997 ≤ exposure time ≤ 20000: Long Exposure Compensation = ( Timer 1 - 1997 ) x ( 90 / 18003 ) + 70
Exposure time* [µs]
20000
15000
10000
8000
4000
2000
Timer 1 determines the exposure time in programmable
and free-run mode. The exposure time is determined by
ExSync in edge-controlled and level-controlled mode.
Table 3-1: Long Exposure Compensation Sample Values
You can set long exposure compensation using either the Camera Configuration Tool Plus (see
section 4.1) or binary commands (see section 4.2).
