C4180)
1
DefectPixelThreshold
– Sets the threshold value for dynamic defective pixel correction.
The sensitivity increases as the value decreases. Defective Pixel Threshold should be set
with the image data output level at about 75% of maximum.
2
HotPixelThreshold
– Sets the threshold value for dynamic hot pixel correction. The
sensitivity of the correction increases as the value decreases. You should set the hot pixel
threshold using the longest expected exposure time with the longest expected frame time
at the maximum expected ambient temperature. The camera should be warmed up for 10
minutes prior to determining the desired threshold.
3.4.7.1
FFC Sequencer
This feature is available only for the 4-channel CXP-6 cameras (C5190, C4191, and C4190)
and is enabled by default. FFC Sequencer is required to apply appropriate FFC table (refer
Flat Field and Noise Correction).
