INTRODUCTION

About Arducam
Arducam has been a professional designer and manufacturer of SPI, MIPI, DVP, and USB cameras since 2012. We also offer customized turnkey design and manufacturing solution services for customers who want their products to be unique.
About Pivariety Camera
Arducam Pivariety is a Raspberry Pi camera solution to take the advantage of using its hardware ISP functions. Using Arducam Pivariety camera modules, users can get better performance and a wider variety of camera, lens options. For a long time, Raspberry Pi users are limited to using the closed-source official supported camera driver and camera modules (V1/V2/HQ).
Now Arducam made it possible to provide well-tuned ISP for Pivariety camera modules with Auto Exposure, Auto White Balance, Auto Gain Control, Lens Shading Correction,etc. This series of cameras use the libcamera framework, they can’t be supported by Raspistill, and the way to access the camera is libcamera SDK(for C++)/libcamera-still/ libcamera-vid/Gstreamer.

SOFTWARE

1. Driver Installation

wget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam- Pivariety- V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh

chmod +x install_pivariety_pkgs.sh
./install_pivariety_pkgs.sh -p kernel_driver

press y to reboot

NOTE: The kernel driver installation only supported by the latest version 5.10. For other kernel versions,please go to our Doc page: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to- install-kernel-driver-for-pivarietycamera/#2-how-to-build-raspberry-pi-kernel- driverfor-arducam-pivariety-camera
You can also visit this doc page to refer to the hardware connection: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/16mp- imx298pivariety-motorized-focus-camera-module/
2. Test the Driver and Camera
After you’ve finished the hardware assembly and driver installation, you can test whether the camera is detected and working.

View the Status of Driver and Camera
dmesg | grep arducam
It will display arducam-variety if the driver is installed successfully and firmware version if the camera can be detected.
The display should be probe failed if the camera can’t be detected, you might have to check the ribbon connection, then reboot the Raspberry Pi.
View the Video Node
The Pivariety camera modules are emulated as the standard video device under /dev/video* node, so you can use the ls command for listing the contents in the /dev folder.
*ls /dev/video -l
Since the camera module is V4L2 compliant, you can use the V4l2 controls to list the supported color space, resolutions, and frame rates.
v4l2-ctl –list-formats-ext
NOTE:** Although the V4L2 interface is supported, only RAW format images can be obtained, without ISP support.

3. Official Libcamera App Installation
./install_pivariety_pkgs.sh -p libcamera_dev
./install_pivariety_pkgs.sh -p libcamera_apps
4. Capture Image and Record Video

Capture image
For example, preview for 5s and save the image named test.jpg
libcamera-still -t 5000 -o test.jpg
Record video
For example, record an H.264 10s video with the frame size 1920W × 1080H
libcamera-vid -t 10000 –width 1920 –height 1080 -o test.h264
NOTE: H.264 format only supports 1920×1080 and below resolution.
Plugin gstreamer installation
Install gstreamer
sudo apt update
sudo apt install -y gstreamer1.0-tools
Preview
gst-launch-1.0 libcamerasrc ! ‘video/xraw,width=1920,height=1080’!videoconvert !autovideosink

5. Control the Focusing Manually

Control via v4l2 -ctl
v4l2-ctl -c focus_absolute =300
Control via script
git clone https://github.com/ArduCAM/ArducamPivariety-V4L2-Driver.git
cd Arducam-Pivariety-V4L2-Driver/focus
python3 FocuserExample.py
Now you can use the up and down on the keyboard to control the focus position

6. Automatically Control the Focusing

Focus once
libcamera-still -t 0 –autofocus
libcamera-vid -t 0 –autofocus
Enable autofocus using F
libcamera-still -t 0 –keypress
press f to trigger autofocus
NOTE: Note: Please install the Arducam latest version of libcamera-dev and libcamera-apps, and update the firmware of Pivariety(contacting Arducam: support@arducam.com) if the camera can not autofocus.
