Table 19: AGC Commands
Command Optional Payload Description
status Display the AGC commands and settings
agcupdinterva XX Number of histograms to collect before doing an
AGC update
saturationlev XXX Sets the digital value at which a pixel is considered
saturated
bdeltalim XXX Sets the minimum brightness delta between the
high and low limit of the cumulative histogram in
conjunction with the “saturationlev” to determine
if the sensor output is saturated under normal
operation
bhidnlim XXX Increase exposure value if “bhipcagc” is lower than
this digital output value
bhipcagc XX Mean brightness high percentage of the
cumulative histogram to remap that AGC
algorithm tries to maintain to “bhitgt” digital value
blopcagc XX Mean brightness low percentage of the
cumulative histogram to remap that AGC
algorithm tries to maintain to 0 digital value
csbin_high XXX Sets the contrast stretch bin high to XXX
csbin_lo XXX Sets the contrast stretch bin low to XXX
bhipccontrast XX.X Percentage of the cumulative histogram at which
the histogram stretching maps to 1023 digital
value output
blopccontrast XX.X Percentage of the cumulative histogram at which
the histogram stretching maps to 0 digital value
output
bhitgt XXX Target brightness that AGC tries to maintain
“bhipcagc”
bhiuplim XXX Decrease exposure value if “bhipcagc” is lower
than this digital output value
cliphisteqlev XXX.XX Histogram clipping equalization level in pixel
percentage
count XX Number of histogram to obtain running average
to calculate AGC statistics
contrast_damp XXX Histograms to average to damp the video contrast
enhancement
evlim XX Maximum percentage change in exposure value
allowed between AGC updates
int_g XX Maximum reduction in exposure value if the scene
is saturated
integtime XXXX Sets camera integration time (in lines) to x if the
AGC is disabled
integr8b4agc 0
1 Update averaging statistics during AGC
Update averaging statistics before AGC
intg_max XXXX Sets the maximum integration time allowed (in
lines) by the AGC. By default the NOCTURN are
shipped with an AGC lookup table that only allows
increase of the integration time to 2120 lines. In
order to use this function for values greater than
2120, the AGC table must be adjusted.
