Gateway routine to auto-exposure methods
[integrationTime,maxSignalVoltage,smallOI] = autoExposure(OI,ISA,[level = 0.95],[aeMethod])
Find an integration time (sec) that will produce a voltage at a
fraction (0 < level < 1) of the voltage swing. The data used to set
the level are from the signal current image plus the dark current
image.
The currently implemented methods are
{'default'} - Calculate only for point with highest luminance
{'luminance'} - Full computation of the response
Yes, more methods will be implemented.
The default method finds the signal voltage for a one sec exposure of the
portion of the optical image with peak illuminance. The exposure routine
then returns an integration time that produces a value of "level" times
the voltage swing.
