Normal AE
When AE Mode =0[h] was selected, the normal AE mode is established. In this AE mode, the gain and exposure time
are automatically adjusted so that the images have the appropriate brightness.
Maximum Exposure time can be set on Normal AE maximum shutter time (0x001-0x002).
Maximum Gain can be set on Normal AE maximum gain (0x004-0x005).
In the normal mode, it is not possible to extend the exposure time beyond the frame rate. This level is referred to as
the maximum exposure time. To extend the exposure time beyond the frame rate, please select Long AE.

Long AE
When the AE mode =1[h] is selected, the long AE control mode is established.
Long AE control makes it possible to expand the frame rate and obtain a longer exposure time. Then long AE
can keep the best image in low luminance.
Exposure time control on normal area can be set on Long AE normal shutter time (0x006 - 0x007).
Gain control on normal area can be set on Long AE low gain (0x00C - 0x00D).
Exposure time control on expanded area can be set on Long AE expanded shutter time (0x008 - 0x009).
Gain control on expanded area can be set on Long AE high gain (0x00E - 0x00F).
Exposure time control on maximum area can be set on Long AE maximum shutter time (0x00A - 0x00B).
Gain control on maximum area can be set on Long AE maximum gain (0x010 - 0x011).
