Both MG and AG are easy to understand.
AG once: Execute automatic gain in the set range once, then stop the adjustment.
RAW-MIPI-AR0234M do not support AG once mode.
RAW-MIPI-AR0234M can not enable AG in ME mode.
===== mgain =====
<code>./mv_mipi_i2c.sh -w -f mgain -p1 [gain] -b your_i2c_bus_number</code>
<code>./mv_mipi_i2c.sh -r -f mgain -b your_i2c_bus_number</code>
Range [0,MAX_Gain]，MAX_Gain varies from sensor to sensor, for example， IMX178 is 48dB.
Read back to confirm the real mgain take effect.
===== aatarget =====
<code>./mv_mipi_i2c.sh -r -f aatarget -b your_i2c_bus_number</code>
<code>./mv_mipi_i2c.sh -w -f aatarget -p1 [1,255] -b your_i2c_bus_number</code>
The target brightness of AE and AG algorithm.
Within the set range, the algorithm will prioritize the increase in exposure time,
and increase the gain if the exposure time reaches the maximum and still cannot reach the set target brightness value.
===== aemaxtime =====
<code>./mv_mipi_i2c.sh -r -f aemaxtime -b your_i2c_bus_number</code>
<code>./mv_mipi_i2c.sh -w -f aemaxtime -p1 [16,1000000/fps] -b your_i2c_bus_number</code>
Maximum exposure time in AE mode.Range[16,1000000]. <u>Note1.</u>
Please read back to confirm the real metime take effect.
===== agmaxgain =====
<code>./mv_mipi_i2c.sh -r -f agmaxgain -b your_i2c_bus_number</code>
<code>./mv_mipi_i2c.sh -w -f agmaxgain -p1 [0,maxgain] -b your_i2c_bus_number</code>
Maximum value of auto gain. The range and step vary according to the model.
Most sensors have a gain step of 0.1dB, some are 0.3dB.
Note：For RAW-MIPI-AR0234M, agmaxgain cannot be configured and remains fixed at 24dB.
===== exptime =====
<code>./mv_mipi_i2c.sh -r -f exptime -b your_i2c_bus_number</code>
Get the current exposure time. This command is valid in any exposure mode.
===== curgain =====
<code>./mv_mipi_i2c.sh -r -f curgain -b your_i2c_bus_number</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] -b your_i2c_bus_number</code>
<code>./mv_mipi_i2c.sh -r -f aaroienable -b your_i2c_bus_number</code>
Whether to enable AAROI statistics function, not enable means full ROI statistics.
===== aaroi =====
<code>./mv_mipi_i2c.sh -w -f aaroi -p1 [x] -p2 [y] -p3 [width] -p4 [height] -b your_i2c_bus_number</code>
<code>./mv_mipi_i2c.sh -r -f aaroi -b your_i2c_bus_number</code>
The AAROI coordinates are relative coordinates within the ROI area. So the area must be smaller than the image ROI.
===== aeag_run_once_save =====
<code>./mv_mipi_i2c.sh -w -f aeag_run_once_save -b your_i2c_bus_number</code>
Execute AE&AG once operation and save the results to the camera as manual values!<br />This is a function that is useful when the camera is installed.
Please make sure that the image preview has already been started before executing this command.
It performs the following operations：
# Set AE and AG range to MAX.
# Run AE once and AG once.
# Wait 5 seconds.
# Check AE once and AG once result.
# Save the previous result to manual mode.
#Run paramsave,save to flash.
===== snsreg =====
<code>./mv_mipi_i2c.sh -r -f snsreg -p1 [sensor reg addr] -b your_i2c_bus_number</code>
Read the sensor's register indirectly via the camera controller unit.
==== Notes ====
Note1: All parameters of exposure time are in microseconds. However, due to the properties of the sensor, the actual exposure time unit of the sensor is 1 line, can not be accurate to 1us.
Note2: AE: Auto exposure; AG: Auto Gain; AA: AE and AG.
Note3: The AAROI coordinates are relative coordinates within the ROI area.
Note4: For RAW Series, there are some functions that are not supported, please refer to the register list for details.
