Description
Measured histogram data (bin 31, range 496...511)
Measured histogram data (bin 30, range 480...495)
Measured histogram data (bin 29, range 464...479)
Measured histogram data (bin 28, range 448...463)
Stall of measurement unit
Selection of clipping levels
Selection of external SOB_NEGLECT_FLAG
External SOB_NEGLECT flag
Signed value added to NEST before low pass filtering
Selection of coupling to low boundary
Scaling factor of the prefilter unit
Controls the updown counting of images. When the number of times
ce_SOB and ce_SAD are in agreement (equal ‘1’) in an image, is
smaller than WANTED_VALUE, unit are counting down; otherwise
counting up.
Lower limit for absolute difference between two adjacent pixels
Upper limit for absolute difference between two adjacent pixels
Horizontal Noise Estimator window start
Vertical Noise Estimator window start
Horizontal NOise Estimator window end
Vertical Noise Estimator window end
The number of times in an image that the number of events
(ce_SOB = ce_SAD) is lower than WANTED_VALUE.
0 = measurement unit active (default)
1 = measurement unit stalled
