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.
- readmodecap
If bit1 in the read value is set to 1, the camera supports 2x2 binning mode.
- 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.
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.
