./mv_mipi_i2c_new.sh -r exptime -b your_i2c_bus_number

Get the current exposure time. This command is valid in any exposure mode.

Unit: microseconds.

7.17.15 curgain

./mv_mipi_i2c_new.sh -r curgain -b your_i2c_bus_number

Gets the current gain. This command is valid in any exposure mode.

7.17.16 aaroienable

./mv_mipi_i2c_new.sh -w aaroienable [0,1] -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -r aaroienable -b your_i2c_bus_number

Whether to enable AAROI statistics function, not enable means full ROI statistics.

7.17.17 aaroi

./mv_mipi_i2c_new.sh -w aaroi [x] [y] [width] [height] -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -r aaroi -b your_i2c_bus_number

The AAROI coordinates are relative coordinates within the ROI area. So the area must be smaller than the image ROI.

7.17.18 exptime_range

./mv_mipi_i2c_new.sh -r exptime_range -b your_i2c_bus_number

Maximum and minimum exposure time in the current mode.

Unit: microseconds.

./mv_mipi_i2c_new.sh -w aeag_run_once_save -b your_i2c_bus_number

Execute AE&AG once operation and save the results to the camera as manual values!
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：

1. Set AE and AG range to MAX.
2. Run AE once and AG once.
3. Wait 5 seconds.
4. Check AE once and AG once result.
5. Save the previous result to manual mode.
6. Run paramsave,save to flash.

7.17.20 snsreg

./mv_mipi_i2c_new.sh -r snsreg [sensor reg addr] -b your_i2c_bus_number

Read the sensor's register indirectly via the camera controller unit.

7.18 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.

8 Configuration Method for Typical Application Scenarios:

8.1 Manual Exposure Mode:

 ./mv_mipi_i2c_new.sh -w expmode 0 -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w gainmode 0 -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w metime exptime_you_want_to_set_us -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w mgain gain_you_want_to_set_dB -b your_i2c_bus_number

 After configuration, read the parameters with the following commands to confirm they have taken effect:

 ./mv_mipi_i2c_new.sh -r exptime -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -r curgain -b your_i2c_bus_number

  Note: The maximum exposure time must be strictly less than the reciprocal of the fps.

8.2 Continuous Auto Exposure Mode:

./mv_mipi_i2c_new.sh -w expmode 2 -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w gainmode 2 -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w aatarget brightness_target -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w aemaxtime [16,1000000/fps] -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w agmaxgain [0,maxgain] -b your_i2c_bus_number

  After continuous imaging for a while, you can read the current actual exposure time and gain using the following commands:

./mv_mipi_i2c_new.sh -r exptime -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -r curgain -b your_i2c_bus_number

8.3 Normal Trigger Mode:

   First, stop the image acquisition to enter a state where the trigger mode can be modified:

   ./mv_mipi_i2c_new.sh -w imgacq 0 -b your_i2c_bus_number

   In the following example, configure the camera for normal hardware trigger mode, where each trigger signal captures 1 image:

./mv_mipi_i2c_new.sh -w trgmode 1 -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w trgsrc 1 -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w trgnum 1 -b your_i2c_bus_number

   You may optionally execute the following two commands to set the trigger edge and delay:

./mv_mipi_i2c_new.sh -w trgedge [0,1] -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w trgdelay [us] -b your_i2c_bus_number

   After configuration, you can start the image acquisition to accept trigger signals:

 ./mv_mipi_i2c_new.sh -w imgacq 1 -b your_i2c_bus_number

8.4 Long Exposure Mode

Some models support long exposure times, such as the MV-MIPI-IMX178M, which supports exposure times up to 100 seconds. The usage is as follows:

1. Stop image acquisition.

./mv_mipi_i2c_new.sh -w imgacq 0 -b your_i2c_bus_number

2. Set exposure and gain to manual mode:

 ./mv_mipi_i2c_new.sh -w expmode 0 -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -w gainmode 0 -b your_i2c_bus_number

3. Read the minimum frame rate:

   ./mv_mipi_i2c_new.sh -r minfps -b your_i2c_bus_number

   r minfps @ current setting is 0.0100 fps

4. Set the current frame rate to 0.016:

   ./mv_mipi_i2c_new.sh -w fps_ex 0.016 -b your_i2c_bus_number

   ./mv_mipi_i2c_new.sh -r fps_ex -b your_i2c_bus_number

5. Read the current exposure time range:

   ./mv_mipi_i2c_new.sh -r exptime_range-b your_i2c_bus_number

6. Set the exposure time:

 ./mv_mipi_i2c_new.sh -w metime 10000000 -b your_i2c_bus_number

./mv_mipi_i2c_new.sh -r exptime-b your_i2c_bus_number

After completing the above configuration, you can proceed to start capturing images.

Please note that if you need to adjust the frame rate during the image acquisition process, you must first stop the acquisition before making the changes.  

After stopping the acquisition, the camera will still complete the capture of the current frame.

The newly set parameters will only take effect afterward.
