By lowering the TbpVerticalStep parameter, the algorithm uses more pixels in
calculation and consequently provides more precise results. On the other hand,
Note
using more pixels in calculation causes the algorithm to be slower and can lead to
a decreased frame rate.
Increasing the TbpFramesToAvg parameter increases the amount of frames used in
averaging, localized single frame tap differences thus have smaller impact on the final
Note
result when tap difference is compared to the threshold. On the other hand, increasing
the number of frames used for averaging increases the delay or reaction time between
detecting the difference between taps and adjusting it.
The operation of the automatic tab balancing algorithm can be controlled via the property GainAutoBalance,
adjusting the gain, and BlackLevelAutoBalance, adjusting the Black Level of the camera. Both have three
operation modes, listed it Table 50.
