Description
under normal operation
bhidnlimlo
xx
If the “bhipcagc” is lower than this digital output value, and
the integration time equal or greater to “mg0max”, the AGC
will switch the gain and NUC tables to operate in high gain
bhidnlim
xx
Reduces exposure or gain if “bhipcagc” is greater than this
digital output value
bhipcagc
xx
Mean brightness high percentage of the cumulative histogram
to remap the AGC algorithm that tries to maintain to “bhitgt”
digital value
blopacagc
xx
Mean brightness low percentage of the cumulative histogram
to remap the AGC algorithm that tries to maintain to 0 digital
value
bhipccontrast
xx
Percentage of the cumulative histogram at which the
histogram stretching maps to 1023 digital value output
blopccontrast
xx
Percentage of the cumulative histogram at which the
histogram stretching maps to 0 digital value output
bhitgt
xx
Target brightness that AGC tries to maintain “bhipcagc”
bhiuplimlo
xx
If the “bhipcagc” is greater than this digital output value and
the integration time equal or smaller than “mg0max”, the AGC
will switch the gain and NUC tables to operate in medium
gain
bhiuplim
xx
increase exposure or gain if “bhipcagc” is lower than this
digital output value
count
xx
Number of histogram to average to calculate AGC statistics
hggain
[0-7]
Gain value used for the “High Gain” setting
hgmin
xx
Minimum integration time (in lines) of the “High Gain” setting
hgmax
xx
Maximum integration time (in lines) of the “High Gain” setting
hgtransdn
xx
Integration time (in lines) to set the sensor to when
transitioning from the “High Gain” to the “Medium Gain”
Setting
hgtransup
xx
Integration time (in lines) to set the sensor to when
transitioning from the “Medium Gain” to the “HighGain”
Setting
int_g
xx
Maximum reduction in percentage of the sensor exposure
when the digital output is saturated
intgtime
xx
Set camera integration time (in lines) to x if the AGC is
disabled
intglolim
xx
Maximum attenuation of the sensor exposure in percentage
during an AGC update
intghilim
xx
Maximum gain of the sensor exposure in percentage during
an AGC update
intgr8b4agc
[0|1]
Sets the AGC averaging statistics to open before (1) or during
(0) an AGC update loop
lggain
[0-7]
Gain values used for the “Low Gain” setting
lgmin
xx
Minimum integration time (in lines) of the “Low Gain” setting
lgmax
xx
Maximum integration time (in lines) of the “Low Gain” setting
lgtransdn
xx
Integration time (in lines) to set the sensor to when
transitioning from the “Medium Gain” to the “Low Gain”
