5. Parentah Setup

This section guides you through connecting and configuring your Arducam 12MP IMX477 HQ Camera with your Raspberry Pi.

5.1 Panyambung Hardware

1. Power Off Raspberry Pi: Ensure your Raspberry Pi is completely powered off and disconnected from its power source before proceeding.
2. Locate Camera Port: Identify the CSI (Camera Serial Interface) port on your Raspberry Pi board. This is typically a long, narrow connector.
3. Sambungkeun Kabel Pita: Gently lift the plastic clip on the CSI connector. Insert the flexible ribbon cable from the camera module into the connector, ensuring the silver contacts on the cable face the silver contacts in the connector. Push the plastic clip back down to secure the cable.
4. Secure Camera Module: Position the camera module as desired, ensuring the ribbon cable is not bent sharply or under tension.

5.2 Software Configuration (Raspberry Pi OS Bullseye and later)

The Arducam IMX477 camera module supports the latest Raspberry Pi OS Bullseye (released Jan 28th, 2022) and libcamera applications. It is not compatible with previous Pi OS (Legacy) versions.

1. Édit config.txt: Buka na config.txt file for editing. You can do this via the terminal:

   sudo nano /boot/config.txt

2. Add Camera Overlay: Tambahkeun garis di handap ieu kana config.txt file:

   dtoverlay=imx477

3. Disable Automatic Camera Detection (Bullseye users): To override automatic camera detection, Bullseye users must also delete or change the camera_auto_detect entry to 0. Find the line:

   camera_auto_detect=1

   And change it to:

   camera_auto_detect=0

4. Enable Glamor Acceleration (for Pi Zero-3 Bullseye users): If you are using a Raspberry Pi Zero, Pi 1, Pi 2, or Pi 3 with Bullseye OS, you may need to enable Glamor acceleration for optimal performance.

   sudo raspi-config

   Arahkeun ka Pilihan canggih → Glamor → Diaktipkeun.
5. Simpen sareng Pareuman deui: Save the changes to config.txt (Ctrl+O, then Enter, then Ctrl+X in nano) and reboot your Raspberry Pi:

   sudo reboot

6. Parentah Operasi

After successful setup, you can use the libcamera tools to capture images and videos with your Arducam HQ Camera.

6.1 Basic Image Capture

To capture a still image, use the libcamera-still paréntah:

libcamera-still -o image.jpg

This command will capture an image and save it as image.jpg in your current directory.

6.2 Basic Video Recording

To record a video, use the libcamera-vid command. For example, to record a 10-second video:

libcamera-vid -t 10000 -o video.h264

This command records video for 10 seconds (10000 milliseconds) and saves it as video.h264.

6.3 Further libcamera Pamakéan

The libcamera suite offers many options for resolution, frame rate, exposure, white balance, and more. For advanced usage and a full list of commands and parameters, refer to the official Raspberry Pi documentation for libcamera parabot.

• libcamera-still --help: Displays options for still image capture.
• libcamera-vid --help: Displays options for video recording.
• libcamera-raw --help: Displays options for raw image capture.
• libcamera-hello --help: Displays options for a preview jandela.

7. Pangropéa

Proper maintenance ensures the longevity and optimal performance of your Arducam HQ Camera.

• Ngabersihan lensa: Use a soft, lint-free microfiber cloth specifically designed for optics to clean the lens. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth (not directly to the lens). Avoid abrasive materials or harsh chemicals.
• Ngaleungitkeun lebu: Use a blower brush or compressed air (designed for electronics) to remove dust from the sensor and board. Do not touch the sensor directly.
• Penanganan: Always handle the camera module by its edges to avoid touching the lens or the sensitive electronic components on the board.
• Panyimpenan: When not in use, store the camera in a clean, dry, and anti-static environment, preferably in its original packaging or a protective case.
• Kaayaan Lingkungan: Avoid exposing the camera to extreme temperatures, high humidity, or direct sunlight for extended periods.

8. Cara ngungkulan

If you encounter issues with your Arducam HQ Camera, refer to the following common problems and solutions.

8.1 Camera Not Detected

• Pariksa sambungan kabel: Ensure the ribbon cable is securely inserted into both the camera module and the Raspberry Pi's CSI port, with the silver contacts facing correctly. The plastic clip on the CSI connector should be fully closed.
• Verify Software Configuration: Double-check that you have correctly added dtoverlay=imx477 ka /boot/config.txt jeung set camera_auto_detect=0 (for Bullseye). Reboot the Raspberry Pi after making changes.
• Kasaluyuan Sistem Operasi: Confirm you are running Raspberry Pi OS Bullseye or a later version. This camera is not compatible with older (Legacy) OS versions.
• Sasayogian tanaga: Ensure your Raspberry Pi has an adequate power supply. Insufficient power can sometimes lead to peripheral detection issues.

8.2 Poor Image Quality / Focus Issues

• Saluyukeun fokus: The M12 lens is interchangeable and may require manual focusing. Gently rotate the lens barrel to achieve sharp focus. Use a test pattern or a known object at a specific distance to aid focusing.
• Lensa bersih: Ensure the lens surface is clean and free from dust, smudges, or fingerprints. Refer to the Maintenance section for cleaning instructions.
• Kaayaan Pencahayaan: While the IMX477 has improved low-light performance, extremely dark environments will still result in noisy images. Ensure adequate lighting for best results.
• Setélan parangkat lunak: Ékspérimén kalawan libcamera parameters such as exposure, gain, and white balance to optimize image quality for your specific environment.

8.3 Performance Issues (Lag, Low Frame Rate)

• Glamor Acceleration: For Pi Zero-3 users, ensure Glamor acceleration is enabled in raspi-config sakumaha anu dijelaskeun dina bagian Setelan.
• Raspberry Pi Model: Older Raspberry Pi models (e.g., Pi Zero, Pi 1, Pi 2) may have limited processing power compared to newer models (Pi 4, Pi 5), which can affect frame rates at higher resolutions.
• Software Load: Close unnecessary applications running on your Raspberry Pi to free up system resources.
• Resolution and Frame Rate Settings: Reduce the capture resolution or frame rate in your libcamera commands if you are experiencing lag.
