• Photography and Videography: Take high-quality photos and record 1080p videos.
• Robotics: Enable vision-based navigation and obstacle detection.
• Time-Lapse Photography: Create stunning time-lapse videos with ease.

The Raspberry Pi Camera Module 3 is available in multiple variants, including standard and wide-angle lenses, as well as visible light and infrared (NoIR) versions. Below are the key technical details:

• Sensor: Sony IMX708
• Resolution: 12 megapixels
• Video Recording: Up to 1080p at 50fps
• Autofocus: Yes
• Field of View (FoV):
  • Standard: 66° horizontal
  • Wide-angle: 102° horizontal
• Connectivity: 22-pin MIPI CSI-2 interface
• Power Supply: 3.3V (via Raspberry Pi)
• Dimensions: 25mm × 24mm × 11.5mm (excluding cable)

The Raspberry Pi Camera Module 3 connects to the Raspberry Pi via the Camera Serial Interface (CSI) port using a 22-pin ribbon cable. Below is the pin configuration for the CSI interface:

1. Connect the Camera Module:

   • Power off your Raspberry Pi.
   • Locate the CSI port on the Raspberry Pi board.
   • Insert the ribbon cable from the camera module into the CSI port, ensuring the metal contacts face the correct direction.
   • Secure the cable by locking the CSI port's connector.

2. Enable the Camera Interface:

   • Boot up your Raspberry Pi.
   • Open a terminal and run the following command to access the Raspberry Pi configuration tool:

     sudo raspi-config
     

   • Navigate to Interface Options > Camera and enable the camera interface.
   • Reboot your Raspberry Pi to apply the changes.

3. Capture Images and Videos:

   • Install the libcamera tools if not already installed:

     sudo apt update
     sudo apt install libcamera-apps
     

   • Use the following commands to capture images or record videos:
     • Capture an image:

       libcamera-still -o image.jpg
       

     • Record a video:

       libcamera-vid -o video.h264 -t 10000
       

       (The -t option specifies the duration in milliseconds.)

• Autofocus Usage: Ensure the subject is within the autofocus range for sharp images.
• Lighting Conditions: Use adequate lighting for better image quality, especially in low-light environments.
• Cable Handling: Avoid bending or damaging the ribbon cable during installation.
• Compatibility: Ensure your Raspberry Pi board supports the Camera Module 3 (e.g., Raspberry Pi 4, 3, or Zero 2 W).

Below is an example Python script to capture an image using the Raspberry Pi Camera Module 3:

from picamera2 import Picamera2

picam2 = Picamera2()

picam2.configure(picam2.create_still_configuration())

picam2.start()

picam2.capture_file("photo.jpg")

picam2.stop()

print("Image captured and saved as 'photo.jpg'")

1. Camera Not Detected:

   • Ensure the ribbon cable is securely connected to the CSI port.
   • Verify that the camera interface is enabled in raspi-config.
   • Check for software updates:

     sudo apt update && sudo apt upgrade
     

2. Poor Image Quality:

   • Ensure the lens is clean and free of dust or smudges.
   • Use proper lighting to improve image clarity.
   • Verify that the autofocus is functioning correctly.

3. Error: "No data received from sensor":

   • Confirm that the camera module is compatible with your Raspberry Pi model.
   • Recheck the ribbon cable connection for proper alignment.

4. Autofocus Not Working:

   • Ensure the subject is within the autofocus range (minimum distance: ~10cm).
   • Update the camera firmware if autofocus issues persist.

• Q: Can I use the Camera Module 3 with older Raspberry Pi models?
  A: The Camera Module 3 is compatible with Raspberry Pi boards that have a CSI port, but performance may vary on older models.

• Q: Does the Camera Module 3 support night vision?
  A: The NoIR version of the Camera Module 3 is designed for low-light and night vision applications.

• Q: What is the maximum video resolution and frame rate?
  A: The Camera Module 3 supports up to 1080p resolution at 50 frames per second.

• Q: Can I use multiple camera modules on a single Raspberry Pi?
  A: Yes, with the appropriate hardware (e.g., a multi-camera adapter), you can connect multiple camera modules.

This concludes the documentation for the Raspberry Pi Camera Module 3.
