5. Setup Guide
5.1 Hardware Connection
- Ensure your Raspberry Pi is powered off and disconnected from any power source.
- Locate the MIPI CSI-2 camera connector on your Raspberry Pi board. This is typically a long, thin slot.
- Gently pull up the plastic clip on the camera connector.
- Insert the appropriate FPC cable (15-pin or 22-pin, depending on your Pi model) into the connector with the silver contacts facing the clip. Ensure the cable is fully inserted and straight.
- Push the plastic clip back down to secure the FPC cable.
- Connect the other end of the FPC cable to the camera module's connector, ensuring the contacts face the correct direction (usually towards the PCB).
- Before powering on, remove the protective film from the camera lens.

5.2 Software Configuration
To enable the camera module on your Raspberry Pi, follow these steps:
- Boot your Raspberry Pi and open a terminal.
- Modify the configuration file. For older Raspberry Pi OS versions, use: sudo nano /boot/config.txt. For the latest Raspberry Pi OS, use: sudo nano /boot/firmware/config.txt.
- Add the following line to the last line of the file: dtoverlay=imx708.
- Change camera_auto_detect=1 to camera_auto_detect=0 if present.
- Save the file and exit the editor (Ctrl+X, then Y, then Enter).
- Reboot your Raspberry Pi: sudo reboot.
- After reboot, test the camera with the command: libcamera-hello -t 0 to preview the camera feed.

6. Operating Instructions
6.1 Basic Image and Video Capture
Once configured, you can use the libcamera tools to capture images and videos:
- Preview: libcamera-hello -t 0 (continuous preview)
- Capture Still Image: libcamera-still -o image.jpg
- Record Video: libcamera-vid -t 10000 -o video.h264 (records for 10 seconds)
Refer to the official Raspberry Pi documentation for more advanced libcamera commands and options.
6.2 Autofocus and HDR Functionality
The camera module features Phase Detection Autofocus (PDAF) for quick and accurate focusing. In most cases, autofocus operates automatically. For specific applications, manual focus control might be available through software commands. The HDR (High Dynamic Range) mode enhances image quality in scenes with high contrast, providing more detail in both bright and dark areas. This mode can be enabled via software settings.
6.3 Customizable Lens Options
The module supports interchangeable M12 or CS mount lenses, allowing for customization based on your project's needs. To change the lens:
- Carefully unscrew the existing lens from the module.
- Gently screw in the new M12 or CS lens.
- Adjust the focus manually if using a manual focus lens, or allow the autofocus system to recalibrate.

7. Maintenance
- Cleaning the Lens: Use a soft, lint-free cloth specifically designed for optics to gently clean the lens. Avoid abrasive materials or harsh chemicals.
- Storage: Store the camera module in a dry, dust-free environment when not in use.
- Firmware Updates: Regularly update your Raspberry Pi OS to ensure compatibility and access to the latest camera drivers and features.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Camera not detected / No image | Incorrect FPC cable connection, software configuration error, incompatible OS version. | Ensure FPC cable is securely and correctly inserted. Verify config.txt settings. Update Raspberry Pi OS to the latest version. Reboot the Pi. |
| Image is blurry or out of focus | Protective film still on lens, autofocus range limitations, manual focus lens not adjusted. | Remove any protective film from the lens. Note that autofocus may have limitations for very close objects (e.g., closer than 10cm). If using a manual lens, adjust it carefully. |
| Poor image quality / Color issues | Lighting conditions, software settings, dirty lens. | Ensure adequate lighting. Check camera software settings for white balance or exposure. Clean the lens with a suitable cloth. |
| Camera module is physically larger than expected | Design difference from official Raspberry Pi cameras. | This module has a 32x32mm footprint. Custom enclosures may be required if standard Raspberry Pi camera cases are too small. |
