Gain Speed
Gain update speed is specified as follows.
(fast)11 - 10 - 01 - 00(slow)
Integration Time Fine
Tune
Integration time fine tuning is performed when AE arrive around AE Fine
Tune Boundary to settle into AE lock state smoothly.
Preamp Gain Fine
Tune
Preamp gain fine tuning is performed when AE arrive around AE Fine Tune
Boundary to settle into AE lock state smoothly.
Anti-Banding
Minimum Break
When AE is still of out lock state despite that AE preamp analog gain
update value exceeds preamp minimum gain value(18h) and integration
time(63h-65h) is reached to AE Anti-Banding Step(6ah-6ch), integration
time(63h-65h) is broken to less than AE Anti-Banding Step(6ah-6ch).
AE Subsampling
Mode
AE statistics is executed on 1/4 of original image data to save power
consumption
AE Analog Gain
Control
AE updates preamp gain register(17h) in order to reach optimum exposure
state
AE Digital Gain
Control
AE updates Y digital gain register(78h) in order to reach optimum exposure
state

Integration time value register defines the time during which active pixel element evaluates photon
energy that is converted to digital data output by internal ADC processing. Integration time is equivalent
to exposure time of general camera so that integration time need to be increased in dark environment
