3.2 ഡ്രൈവർ ഇൻസ്റ്റലേഷൻ
The Arducam Mini IMX477 camera requires specific kernel drivers to function correctly with your Nvidia Jetson board. Please note the following critical information:
- Kernel Driver Dependency: This camera relies on kernel drivers. A specific driver version is typically required for each kernel version.
- JetPack Compatibility: Versions of JetPack earlier than 4.3 (L4T 32.3.1) are not supported. Ensure your Jetson board is running a compatible or newer JetPack version.
- Kernel Updates: Upgrading or downgrading your operating system often results in a kernel version change. If this occurs, you will need to reinstall a matching camera driver.
- Future Updates: Future JetPack or kernel updates may necessitate new driver releases from Arducam. Check the official Arducam documentation or support channels for the latest drivers.
Refer to the official Arducam documentation for your specific Jetson board and JetPack version for detailed driver installation instructions. Typically, this involves downloading and compiling the appropriate driver package.
4. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once the camera is physically connected and the correct drivers are installed, you can begin using it with your Nvidia Jetson board. The camera interfaces via MIPI CSI-2, and can be accessed using standard Linux camera APIs and tools available on the Jetson platform.
4.1 Basic Image and Video Capture
You can typically use command-line tools or programming libraries (e.g., GStreamer, OpenCV, or `libcamera` if supported by your JetPack version) to capture images and video. Examples of basic operations include:
- സ്റ്റിൽ ഇമേജ് ക്യാപ്ചർ: Capture high-resolution images up to 4056x3040 pixels.
- വീഡിയോ റെക്കോർഡിംഗ്: Record video at various resolutions and frame rates, including 1920x1080 at 60 frames per second (fps).
Consult the Nvidia Jetson developer documentation and Arducam's specific software examples for detailed commands and programming interfaces relevant to the IMX477 sensor.

6. പരിപാലനം
To ensure the longevity and optimal performance of your Arducam Mini 12.3MP HQ Camera, follow these maintenance guidelines:
- കൈകാര്യം ചെയ്യൽ: Always handle the camera module by its edges to avoid touching the lens or sensor surface. Electrostatic discharge (ESD) precautions are recommended.
- ലെൻസ് വൃത്തിയാക്കൽ: Use a soft, lint-free microfiber cloth specifically designed for optics to gently clean the lens. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth, not directly to the lens.
- സംഭരണം: When not in use, store the camera in a clean, dry, and dust-free environment, preferably in its original packaging or an anti-static bag.
- പരിസ്ഥിതി വ്യവസ്ഥകൾ: ഉയർന്ന താപനിലയിലോ, ഉയർന്ന ആർദ്രതയിലോ, നേരിട്ടുള്ള സൂര്യപ്രകാശത്തിലോ ക്യാമറ ദീർഘനേരം തുറന്നുവെക്കുന്നത് ഒഴിവാക്കുക.
