Arducam 12MP IMX708 Autofocus Camera Module 3 w/ HDR & PDAF for Raspberry Pi

Connect the camera's flexible flat cable (FFC) to the Raspberry Pi's CSI (Camera Serial Interface) port, typically located between the Ethernet and HDMI ports. Ensure the cable's conductive pins face away from the Ethernet port. You may need to enable the camera interface in the Raspberry Pi OS via 'sudo raspi-config' under 'Interface Options'. The module is powered directly through the CSI connector, requiring no external power supply.

Use the standard Raspberry Pi Camera software libraries. For Python, the 'picamera2' library is recommended for modern OS versions. You can install it via 'sudo apt update && sudo apt install -y python3-picamera2'. For C/C++ or other languages, you can utilize the underlying libcamera framework. Arducam may also provide specific examples or tuning files for the IMX708 sensor on their official GitHub repository or documentation website.

The Phase Detection Autofocus (PDAF) functionality is hardware-based, but you must use software libraries that support autofocus control. In your application code (e.g., using picamera2), you can set the focus mode to 'auto' or trigger a focus sweep. The camera will automatically adjust the lens position. For fixed-focus applications, you can also lock the focus at a specific distance through the API.

Yes, the module supports video recording. At its full 12MP resolution, the frame rate will be limited. For smoother video, you can use lower resolutions like 1080p (1920x1080) or 720p (1280x720), which support higher frame rates (e.g., 30 fps or 60 fps). The exact supported modes depend on the Raspberry Pi model and the software library's implementation of the IMX708 sensor driver.

HDR (High Dynamic Range) mode is beneficial in scenes with extreme contrast between bright and dark areas, such as a room with a sunny window. It captures multiple exposures and combines them to preserve detail in both shadows and highlights, preventing blown-out skies or pitch-black interiors. Enable HDR via the camera software API when your scene has challenging lighting that a single exposure cannot properly capture.
