How to use Binning Mode on MV Series Camera
Applicable Camera Modules:
| Series | Model |
|---|---|
| MV Series | MV-MIPI-GMAX4002M |
1 Capability Verification and Configuration
The "mv_mipi_i2c_new.sh" script can be used to verify the camera’s "readmode" capabilities and configure the current settings.
1.1 readmodecap
If bit1 in the read value is set to 1, the camera supports 2x2 binning mode.
1.2 readmode
Use the following command to enable binning mode:
./mv_mipi_i2c_new.sh -w readmode 1 -b your_i2c_bus_number
After configuration, verify the mode with:
./mv_mipi_i2c_new.sh -r readmode -b your_i2c_bus_number
When 2x2 binning mode is enabled, the camera automatically adjusts parameters such as maximum resolution, current ROI region, and maximum frame rate.
Verify these parameters using:
./mv_mipi_i2c_new.sh -r maxwh -b your_i2c_bus_number
./mv_mipi_i2c_new.sh -r roi -b your_i2c_bus_number
./mv_mipi_i2c_new.sh -r maxfps -b your_i2c_bus_number
./mv_mipi_i2c_new.sh -r fps -b your_i2c_bus_number
For the MV-MIPI-GMAX4002M, you can still freely configure the ROI region, frame rate, and lanenum in 2x2 binning mode.
1.3 paramsave
After configuring "readmode", save the settings to the camera’s non-volatile memory with:
./mv_mipi_i2c_new.sh -w paramsave -b your_i2c_bus_number
2 Usage
For embedded platforms like Jetson, Raspberry Pi, and Rockchip, the camera drivers do not support direct "readmode" configuration. Use the script mentioned above.
Recommendations:
1. After saving the "readmode" settings, fully power off and restart the system.
2. Upon reboot, the camera will operate in binning mode as seamlessly as in standard mode.
