3. Panduan Persediaan

Follow these steps to properly connect and configure your ArduCam 64MP Autofocus Camera Module with your Raspberry Pi.

1. Prepare your Raspberry Pi: Ensure your Raspberry Pi is powered off and disconnected from any power source. It is recommended to use Raspberry Pi OS Bullseye (32/64bit) for optimal performance.
2. Locate the CSI-2 Connector: Identify the MIPI CSI-2 camera connector on your Raspberry Pi board. This is typically a long, thin slot.
3. Sambungkan Kabel Reben: Gently pull up the plastic clip on the CSI-2 connector. Insert the flexible ribbon cable from the ArduCam module into the connector, ensuring the silver contacts on the cable face the corresponding contacts in the connector. Push the plastic clip back down to secure the cable.
4. Selamatkan Modul: Position the camera module securely, ensuring it does not interfere with other components.
5. Power On and Configure: Reconnect power to your Raspberry Pi. Once booted, open a terminal and run sudo raspi-config. Navigate to 'Interface Options' -> 'Camera' and enable the camera interface. Reboot your Raspberry Pi if prompted.
6. Install ArduCam Software (if necessary): Depending on your specific application and Raspberry Pi OS version, you may need to install additional ArduCam drivers or software. Refer to the official ArduCam documentation for the latest installation instructions.

4. Arahan Operasi

Once the camera module is set up, you can begin capturing images and videos. The operation typically involves using command-line tools or programming libraries.

4.1 Taking Still Images

• To capture a high-resolution still image (up to 9152 x 6944 pixels), use the appropriate camera command or library function for your Raspberry Pi OS.
• The autofocus feature will automatically adjust the lens for optimal sharpness. Ensure your subject is within the 8cm to infinity focus range.
• Supported output formats include JPEG, YUV, RGB, and RAW10.

4.2 Merakam Video

• The module supports various video resolutions and frame rates: 1080p at 30FPS, 720p at 60FPS, and 640x480p at 60/90FPS.
• Select the desired video mode based on your project requirements. Higher resolutions and frame rates will consume more processing power and storage.
• The autofocus system will continuously adjust during video recording to maintain clarity.

4.3 Autofocus Control

The ArduCam 64MP module features an autofocus lens. In most standard applications, the autofocus will operate automatically. For advanced users, specific libraries or commands might allow for manual focus control or adjustment of autofocus parameters. Consult ArduCam's documentation for detailed programming interfaces.

5. Penyelenggaraan

Proper care will extend the lifespan and maintain the performance of your camera module.

• Pembersihan Kanta: Use a soft, lint-free microfiber cloth specifically designed for optics to gently clean the lens. Avoid using abrasive materials or harsh chemicals.
• Ribbon Cable Handling: Always handle the flexible ribbon cable with care. Avoid sharp bends, twists, or excessive force, as this can damage the conductors.
• Storan: When not in use, store the camera module in a dry, dust-free environment, preferably in its original anti-static packaging.
• Keadaan Persekitaran: Avoid exposing the module to extreme temperatures, high humidity, or direct sunlight for prolonged periods.

6. Penyelesaian masalah

If you encounter issues with your ArduCam 64MP module, refer to the following common troubleshooting steps:

• Kamera Tidak Dikesan:
  • Ensure the ribbon cable is correctly and securely inserted into both the camera module and the Raspberry Pi's CSI-2 connector.
  • Verify that the camera interface is enabled in your Raspberry Pi OS (sudo raspi-config -> Interface Options -> Camera).
  • Check if your Raspberry Pi OS is up to date.
• Kualiti Imej/Video Lemah:
  • Pastikan kanta bersih dan bebas daripada habuk atau kotoran.
  • Provide adequate lighting for your scene. Low light conditions can affect image quality.
  • If using manual focus (where applicable), ensure the focus is correctly set for your subject distance.
• Autofokus Tidak Berfungsi:
  • Ensure there is sufficient light and contrast in the scene for the autofocus system to detect edges.
  • Check for any software settings that might disable or interfere with autofocus.
• Modul Terlalu Panas:
  • Ensure adequate ventilation around the Raspberry Pi and camera module, especially during prolonged use or high-resolution video recording.

7. Petua Pengguna

Based on common user experiences and inquiries, here are some tips for getting the most out of your ArduCam 64MP module:

• For best results with 64MP resolution, ensure you are using a compatible Raspberry Pi platform like the Raspberry Pi 4B or Compute Module 4. Older models may be limited to 16MP superpixel resolution.
• Always use the recommended Raspberry Pi OS Bullseye (32/64bit) to ensure compatibility with the latest camera drivers and features.
• Experiment with different output formats (JPEG, YUV, RGB, RAW10) to find the best balance between file size, processing speed, and image quality for your specific application. RAW10 offers the most post-processing flexibility.
• When integrating into custom enclosures, ensure the lens is unobstructed and has enough clearance for autofocus movement.

8. Soalan Lazim (FAQ)

Q: Is this camera compatible with all Raspberry Pi models?

A: The camera is physically compatible with most Raspberry Pi models that have a CSI-2 connector. However, full 64MP resolution is only supported on Raspberry Pi 4B and Compute Module 4. Other models like Pi 2, 3, Zero W, and Zero 2 W will operate at 16MP superpixel resolution.
