The target brightness of AE and AG algorithm.
Within the set range, the algorithm will prioritize the increase in exposure time,
./mv_mipi_i2c.sh -r -f aatarget
and increase the gain if the exposure time reaches the maximum and still cannot reach the set target brightness value.

===== exptime =====
<code>./mv_mipi_i2c.sh -r -f exptime</code>
./mv_mipi_i2c.sh -w -f aaroienable -p1 [0,1]
Get the current exposure time. This command is valid in any exposure mode.
./mv_mipi_i2c.sh -r -f aaroienable
===== curgain =====
<code>./mv_mipi_i2c.sh -r -f curgain</code>
Gets the current gain. This command is valid in any exposure mode.

===== aaroienable =====
<code>./mv_mipi_i2c.sh -w -f aaroienable -p1 [0,1]</code>
<code>./mv_mipi_i2c.sh -r -f aaroienable</code>
Whether to enable AAROI statistics function, not enable means full ROI statistics.

<code>./mv_mipi_i2c.sh -r -f aaroi</code>
The AAROI coordinates are relative coordinates within the ROI area. So the area must be smaller than the image ROI.
