agcupdinterva
XX
Number of histogram 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
